General

Changes or modifications not expressly approved by Motorola could void the user’s authority to

operate the system.

NOTE: This system has achieved Type Approval in various countries around the world. This means

that the system has been tested against various local technical regulations and found to comply. The

frequency band in which the system operates is ‘unlicensed’ (except from the 4.9 Ghz product) and

the system can be used provided it does not cause interference. Further, it is not guaranteed

protection against interference from other products and installations.

1

The system has basically been shown to comply with the limits for emitted spurious radiation for a

1

Class B digital device

, pursuant to Part 15 of the FCC Rules in the USA as well as comparable

regulations in other countries. This equipment generates uses and can radiate radio frequency energy

and, if not installed and used in accordance with the instructions, may cause harmful interference to

radio communications. However, there is no guarantee that interference will not occur in a particular

installation.

If this equipment does cause harmful interference to other equipment, which can be determined by

turning the equipment off and on, the user is encouraged to try to correct the interference by one or

more of the following measures:

• Reorient or relocate the Outdoor Unit (ODU).

• Increase the separation between the equipment and ODU.

• Connect the equipment into a power outlet on a circuit different from that to which the

receiver is connected.

Consult your installer or supplier for help.

Deployment and Operation

The Radio Regulations of various countries’ limits constrain the operation of radio products generally.

In particular the local regulator may limit the amount of conducted or radiated transmitter power and

may require registration of the radio link.

The power transmitted by the PTP 400 Series is controlled by the use of Region-specific License

Keys.

The following examples show how the regulatory limits apply in some specific countries at the current

time. Operators should note that regulations are subject to change.

Contact your supplier/installer to ensure that your product is set for the correct License Key for your

Country/Region and to ensure that you have fulfilled all the local regulatory requirements, especially if

you are intending to use a link with external antennas. Footnotes to the table below indicate countries

where registration of the link is currently mandatory.

2 Avoiding Hazards

2.1 Preventing Overexposure to RF Energy

Caution To protect from overexposure to RF energy, install the radios for the PTP 400 family

of wireless solutions so as to provide and maintain the minimum separation distances from all

persons as shown in

When the system is operational, avoid standing directly in front of the antenna. Strong RF

fields are present when the transmitter is on. The Outdoor Unit (ODU) must not be deployed

in a location where it is possible for people to stand or walk inadvertently in front of the

antenna.

At these and greater separation distances, the power density from the RF field is below

generally accepted limits for the general population.

2.1.1 Calculations for Separation Distances and Power Compliance Margins

Note: These are conservative distances that include compliance margins. In the case of the

reflector, the distance is even more conservative because the equation used models the

reflector as a point source and ignores its physical dimensions.

Limits and guidelines for RF exposure come from:

• US FCC limits for the general population. See the FCC web site at

and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal

Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC

Table 3.

http://www.fcc.gov,

OET Bulletin 65.

• Health Canada limits for the general population. See the Health Canada web site at

http://www.hc-sc.gc.ca/rpb and Safety Code 6.

• ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for

the general public. See the ICNIRP web site at

Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.

3.3 Product Description

This User Manual is specifically written for the PTP 400 Series of point-to-point broadband

wireless solutions. The PTP 400 Series Bridge has been developed to provide Point-to-Point

data connectivity via a 4.9 GHz, 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at

broadband data rates. The PTP 400 Series Bridge is aimed at a wide range of applications.

An example application is an enterprise that has a requirement to connect together the Local

Area Network (LAN) of two or more buildings as shown in

Figure 1.

Figure 1 - Typical PTP 400 Series Bridge Deployment

The PTP 400 Series Bridge offers true non-line-of-sight (NLOS) operation by using a

combination of Orthogonal Frequency Division Multiplex (OFDM) modulation and Multiple-In

Multiple-Out (MIMO) techniques. These technologies enable the PTP 400 Series Bridge to

drive through foliage and around buildings to such an extent that almost universal coverage

can be expected at short range.

A PTP 400 Series Bridge system consists of a pair of identical devices that are deployed one

at each end of the link. At installation, the user sets up one unit as the Master and the other

as the Slave. Either unit can be configured as master or slave.

26

Each end of the link consists of:

• An integrated outdoor transceiver unit containing all the radio and networking electronics

hereafter referred to as the Outdoor Unit (ODU).

• An indoor connection box containing a mains power supply, status indicators and network

connection. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus).

• Units will normally be supplied pre-configured as a link.

Power is fed into the PIDU Plus from the mains via a standard “figure of eight” mains plug.

The network connection is presented to the user at the PIDU Plus via an RJ45 socket.

Connection between the ODU and PIDU Plus is made using standard shielded CAT5 UV

resistant cable. The spare twisted pairs of the cable are used to feed power from the PIDU

Plus to the ODU.

27

3.3.1 The Outdoor Unit (ODU)

The ODU (

Also shown in

single CAT 5 cable feeds the unit. Power is fed to the unit via the brown/brown white pair

connected to pins 7 and 8 and the blue/blue white pair connected to pins 4 and 5 of the RJ45

plugs and sockets employed. It should be noted that this powering arrangement is not

standard Power over Ethernet (PoE). The ODU for the PTP 400 Series Bridge should only be

deployed using the supplied PTP 400 Series Bridge Power Indoor Unit (PIDU Plus).

WARNING: All four power conductors MUST be connected.

Figure 2) is a self-contained unit. It houses both radio and networking electronics.

Figure 2 is a Lightning protection unit, see Section 11 “Lightning Protection”. A

Figure 2 - PTP 400 Series Bridge Outdoor Unit (ODU)

28

3.3.2 The Power Indoor Unit - PIDU Plus

The PTP 400 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the

mains supply. The PIDU Plus also houses a status indicator driven from the ODU.

Figure 3 - Power Indoor Unit (PIDU Plus) – PTP 400 Series

The front panel contains indicators showing the status of the power and Ethernet

connections. The power indicator is illuminated when the PIDU Plus is receiving mains power.

The Ethernet indicator normally illuminates when the Ethernet link is working, flashing when

there is Ethernet activity. The fact that it lights also indicates that the ODU is powered. At

power up the LED will flash 10 times to indicate that a correct start up sequence has

occurred. See Section

9 for further fault finding information.

The bottom of the PIDU Plus houses the Ethernet connection via RJ-45 socket, an entry point

for the PIDU Plus/ODU cabling and the Recovery Switch.

so care should be taken to account for voltage drop over the ODU to PIDU Plus cable.

WARNING: When using alternate DC supplies the supply MUST comply with the following

requirements:

• The voltage and polarity is correct and is applied to the correct terminals in the PTP 400

Series Bridge PIDU Plus

• The power source is rated as SELV

• The power source is rated to supply at least 1A continuously, and

• The power source cannot provide more than the Energy Hazard Limit as defined by

IEC/EN/UL6090, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA)

Also on the left hand side of the PTP 400 Series Bridge PIDU Plus connects and jumpers can

be found that allow the remote connection of power LED, Ethernet LED and Recovery switch.

The connection instructions can be found in Section

3.3.4 Remote LEDs and Recovery Switch

The PTP 400 Series Bridge PIDU Plus provides a facility to connect remote LEDs and

Recovery switch allowing the PIDU Plus to be mounted inside an enclosure. At the left end of

the PIDU Plus under the ODU connection cover can be found three jumpers and a PCB

header. Jumpers J906 and J907 should be removed and connection to the remote LEDs and

Recovery switch made to J908 as shown in

Figure 9 - Remote LED and Recovery Switch Wiring

Figure 9.

3.3.5 Cables and Connectors

The cable used to connect the PTP 400 Series PIDU Plus to the ODU can be any standard

CAT 5 type provided that it is suitable for outdoor deployment. Motorola recommends that

cables to the specification below be used.

NEC/CEC: CMR (ETL) C (ETL) 75C SUN RES OIL RES II

Failure to use the recommended (or equivalent) standard of cable may invalidate the

system’s safety certification.

The PIDU Plus/ODU cable may be unscreened (UTP) or screened (STP). However,

unscreened cables reduce the system’s ability to cope with nearby lightning strikes. If

lightning activity is common in the area of deployment, the use of screened cable is highly

recommended. See Section

11 “Lightning Protection”.

33

The connection between the PTP 400 Series Bridge PIDU Plus and the user’s equipment can

be made using any standard CAT5 patch cable. The RJ45 Ethernet connection is presented

as a piece of network equipment. However as automatic MDI/MDI-X sensing and pair

swapping is employed a crossed or straight through Ethernet patch cable can be used for

connection to another piece of networking equipment or directly to end user equipment.

It should be noted that the PIDU Plus provides continuity between the screen on the ODU to

PIDU Plus cable and screen on the PIDU Plus-User equipment cable. If continuity of the

screening is desired from the ODU to the PIDU Plus to the user’s equipment, CAT5 STP

cable and connectors should be used for the latter connection. CAT5 STP cable between the

PIDU Plus and the user’s equipment will provide additional protection against surges induced

on the Ethernet connections.

3.3.6 Surge Arrestor

The PTP 400 Series Bridge PIDU Plus does not provide lightning or surge suppression.

Should lightning or surge suppression be required a separate Ethernet surge suppressor

should be used and appropriately earthed. Suitable surge suppressors can be sourced from

your Motorola Point-to-Point Distributor or Solutions Provider. The ODU is protected by built-

in surge suppression as standard. See

3.3.7 Mounting Brackets

The PTP 400 Series Bridge is supplied with a mounting bracket suitable for mounting the

ODU to a pole of 25mm (1”) to 75mm (3”) in diameter. For more details on mounting, see

section

7 “Installation”.

The bracket allows for adjustment in both azimuth and elevation.

The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the

cables dressed to a cable channel. Remember to leave space for access to the recovery

button. See section

11 “Lightning Protection”.

7.7.6.

34

3.3.8 Configuration and Management

Configuration and Management of the PTP 400 Series Bridge is implemented using an inbuilt

web server hosting a number of Configuration and Management web pages. This approach

allows Configuration and Management to be carried out on any standard web browsing

technology. The PTP 400 Series Bridge can also be managed remotely using the SNMP

management protocol. Connection to the bridge is via the Ethernet connection carrying the

bridge network traffic. Connection to the unit is via a preset IP address. This address can be

changed via the Network Interface Configuration web page. A full explanation of the available

web pages and their use can be found in section

3.4 Warranty

4 Product Architecture

The PTP 400 Series Bridge consists of an identical pair of unit’s deployed one at each end of

the link. The radio link operates on a single frequency channel in each direction using Time

Division Duplex (TDD). One unit is deployed as a master and the other as a slave. The

master unit takes responsibility for controlling the link in both directions.

The non-line-of-sight (NLOS) aspects of the product are provided by Multiple-Input Multiple-

Output (MIMO), coupled with Orthogonal Frequency Division Multiplexing (OFDM)

modulation.

The PTP 400 Series Bridge has been developed to operate within a selection of frequency

bands.

The current product range supports:

• USA 4.9 GHz National Public Safety Band (4.940-4.990 GHz) - 49400

• ETSI 5.4 GHz license exempt band B (5.470-5.725 GHz) - 54400

• ETSI 5.8 GHz license exempt band C (5.725-5.850 GHz) and the USA 5 GHz ISM band

(5.725-5.850 GHz) - 58400

The PTP 400 Series Bridge has been designed to coexist with other users of the band in an

optimal fashion using a combination of Transmit Power Control (TPC), Planned Frequency

Allocation or Dynamic Frequency Selection (DFS) and antenna beam shape.

In order to maintain link availability, the product employs adaptive modulation techniques that

dynamically reduce the data rate in severe or adverse conditions. To the data network the

PTP 400 Series Bridge is implemented as a learning bridge. A learning bridge builds up a

picture of which addresses are connected to which port. This means that it will not bridge a

packet if it knows that the destination address is connected to the same port on which the

bridge saw the packet.

Figure 10 illustrates the PTP 400 Series Bridge layer diagram.

36

Figure 10 - PTP 400 Series Bridge Layer Diagram

The PTP 400 Series Bridge functionality has been extended to encompass the specification

IEEE 802.1p. IEEE 802.1p uses Ethernet packets extended by 4 bytes, as specified in IEEE

802.1q for VLAN tagging, to prioritize packets over the wireless interface. The PTP 400

Series Bridge will forward all VLAN tagged packets regardless of the VLAN ID value.

Each unit in the link is manageable through an IP connection. Standard IP protocols are

utilized for all management functions e.g. HTTP, SNMP, etc.

The PTP 400 Series Bridge is fully software upgradeable. New software images are first

downloaded from the Motorola website

http://www.motorola.com/ptp to a convenient

computer. The image is then uploaded to the ODU via the web management page described

in Section

8.3.7 “Software Upgrade”. Once the image transfer has completed successfully the

image is written to memory. On completion of this process the unit can be rebooted to use the

newly uploaded image. Should this process fail the unit will revert to a protected image

installed during manufacturing to allow the unit to be recovered.

5 General Considerations

5.1 Spectrum Planning

The PTP 400 Series Bridge has three frequency variants in its product range.

Band Definition Frequency

Coverage

4.9 GHz USA National Public Safety Band 4940-4990 MHz 10 MHz 5 MHz

5.4 GHz ETSI 5 GHz band B, USA UNII Band 5470-5725 MHz 11 MHz 12 MHz

5.8 GHz USA ISM Band / ETSI 5 GHz band C 5725-5850 MHz 11 MHz 6 MHz

Table 6 - PTP 400 Series Bridge Frequency Variants

There are two distinct approaches to spectrum planning:

• First, an operator can utilize the default spectrum management mode i-DFS

(intelligent Dynamic Frequency Selection). This mode uses the PTP 400 Series

Bridge’s ability to measure the interference levels in all channels to build up a picture

of the interference / noise levels in all channels. The PTP 400 Series Bridge uses

statistical techniques to select the most appropriate transmit and receive channels.

i-DFS can be influenced in its channel decision process by selectively barring

Channel

Channel

Raster

channels from use. The use of this functionality is described in detail in section

Spectrum Management”.

“

• Second, when detailed control of the spectrum allocation is required it is

recommended that the fixed frequency mode is used to statically allocate transmit

and receive channels.

Table 7 - PTP 400 Series Bridge Region Code Definitions

When shipped from the factory, units are configured as follows:

• 4.9 GHz PTP 400 Series Bridge – Region Code 14

• 5.4 GHz PTP 400 Series Bridge – Region Code 9

6

• 5.8 GHz PTP 400 Series Bridge – Region Code 1

WARNING To meet the regulatory requirements of your region you should set the correct

Region Code by obtaining a new License Key from your reseller or distributor.

5.3 Operational Restrictions

5.3.1 Radar Avoidance

Radar Avoidance requires that equipment used in the region:

• Detects interference from other systems and avoids co-channel operation with these

systems, notably radar systems.

• Provide on aggregate a uniform loading of the spectrum across all devices.

To address the primary aims the Spectrum Management algorithm implements a radar

detection function which looks for impulsive interference on the active channel only. If

impulsive interference is detected Spectrum Management will mark the current active channel

as having detected radar and initiate a channel hop to an available channel. The previous

active channel will remain in the radar detected state for thirty minutes after the last impulsive

interference pulse was detected. After the thirty minutes have expired the channel will be

returned to the available channel pool.

6

Note that the Quickstart Guide also contains the license keys for region 10. This bars operation in

the Band 5600 – 5650 MHz and MUST be used for equipment depoyed in Canada and Australia.

40

The radar detection algorithm will always scan the active channel for 60 seconds for radar

interference before using the channel. This compulsory channel scan will mean that there is a

60-seconds service outage every time radar is detected and that the installation time is

extended by 60 seconds even if there is found to be no radar on the channel.

NOTE: On system installation or start-up this extends the initial scan time of the Master unit

by 60 seconds.

To address the “provide aggregate uniform loading of the spectrum across all devices”

requirement, the channel selection algorithm will choose a channel at random from a list of

available channels. The channel selection algorithm is initiated at link initialization and when

radar interference is detected.

5.3.2 RTTT Avoidance and Other Channel Use Restrictions

Where regulatory restrictions apply to certain channels these channels are barred. The user

should note that the number of channels barred is dependant on the channel raster selected.

For example see the effect of the UK RTTT channel restrictions in

Figure 11. Barred channels

are indicated by a “No Entry” symbols displayed on the “Spectrum Management” web page,

see section

8.3.10 “Spectrum Management Control - With Operational Restrictions ”.

5.4 4.9 GHz Specific Frequency Planning Considerations

The current 4.9 GHz variant does not require the operator to adjust the lower center

frequency to achieve full band coverage. The channels are set as shown in

Figure 12 - 4.9 GHz Spectrum Settings

5.4.1 Raster Considerations

The 4.9 GHz variant operates on a fixed 5 MHz channel raster that is set to odd center

frequencies. See

5.5.7 Transmit Power Reduction at the Band Edges

Operation at or near the 5.8 GHz band edges can result in a lower maximum transmit power.

In some configurations the PTP 400 Series Bridge reduces the power when operating at the

edge channels. The amount of reduction if any is dependant on the local regulator authority of

the region of operation. These currently only affect systems configured with Region Code 1.

The power reduction in the edge channels is presented in

Figure 15 - 5.8 GHz Band Edge TX Power Reduction (Region Code 1 Only)

5.6 Distance

Figure 15.

The PTP 400 Series Bridge will operate at ranges from 100 m (330 feet) to 200 km (124

miles), within four modes 0-5km, 0-40km, 0-100km and 0-200km. Operation of the system will

depend on obstacles in the path between the units. Operation at 40 km (25 miles) or above

will require a near line-of-sight path. Operation at 100m (330 feet) could be achieved with one

unit totally obscured from the other unit, but with the penalty of transmitting at higher power in

a non-optimal direction, thereby increasing interference in the band. This subject is covered in

more detail in section

6.1.3 “Path Loss Considerations“.

5.7 Networking Information

The PTP 400 Series Bridge operates as a transparent Ethernet bridge. Each unit requires an

IP address. This IP address is for management purposes only and it plays no part in the

operation of the system. IP addresses are assigned during initial configuration as described in

section

7.2 “Installation Procedure”.

45

5.8 Lightning Protection

The amount of lightning protection is dependent on regulatory requirements and the end user

requirements. The standard ODU for the PTP 400 Series Bridge is fitted with surge limiting

circuits and other features to minimize the risk of damage due to nearby lightning strikes.

These standard features may require some additional equipment to be configured as part of

the system installation to be fully effective. Motorola recommends the use of screened cable

and surge arrestor to protect connected equipment from nearby strikes.

The PTP 400 Series Bridge is not designed to survive direct lightning strikes. For this reason

the unit should not be installed as the highest point in a localized area, unless specific

precautions are taken. See section

5.9 Electrical Requirements

The PTP 400 Series Bridge is supplied with a variable input voltage (90-264V, 47-63Hz AC)

inline power supply unit which is incorporated into the PTP 400 Series Power Indoor Unit

(PIDU Plus). The PTP 400 Series Bridge requires one mains supply outlet at each end of the

link.

Alternately, the PTP 400 Series Bridge may be powered by a DC supply (45-55V) though the

terminals provided under the left cover on the PIDU Plus.

11 “Lightning Protection”.

6 Site Planning

6.1 Site Selection Criteria

The following are guidelines for selecting the installation location of the ODU and PIDU Plus

for the PTP 400 Series Bridge.

6.1.1 ODU

6.1.2 PTP 400 Series Bridge PIDU Plus

Site Selection

When selecting a site for the ODU the following should be taken into consideration:

• That it is not possible for people to stand or walk inadvertently in front of the antenna.

• Height and location to achieve the best radio path

• Height in relation to other objects with regard to lightning strikes

• Protection from the weather

• Aesthetics and planning permission issues

• Distance from the PIDU Plus and connected equipment (Maximum cable run ODU to

connected equipment is 100m [330 feet])

• Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to the

ODU is 100m [330 feet] minus the length of the cable from the PIDU Plus to the

connected equipment)

When selecting a site for the PIDU Plus the following should be taken into consideration:

• Availability of a mains electricity supply

• Accessibility for viewing status indicators and pressing reset switch (See section

Site Selection

3.3.2

“The Power Indoor Unit (PIDU Plus)” and section

47

9 “Fault Finding”

+

6.1.3 Path Loss Considerations

The path loss is the amount of attenuation the radio signal undergoes between the two ends

of the link. The path loss is the sum of the attenuation of the path if there were no obstacles in

the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss)

and a margin to allow for possible fading of the radio signal (Fade Margin).

6.1.4 Aggregate Ethernet throughput rate versus maximum link loss

The equipment capability is given in

Table 8 and Table 9. It gives the Ethernet throughput

rate versus link loss for the PTP 400 Series Bridge in both modes. Adaptive modulation will

ensure that the highest throughput that can be achieved instantaneously will be obtained

taking account of propagation and interference. The calculation of

performed to judge whether a particular link can be installed. When the link has been installed

web pages provide information about the link loss currently measured by the equipment both

Equation 1 needs to be

instantaneously and averaged. The averaged value will require maximum seasonal fading to

be added and then the radio reliability of the link can be computed.

The full calculation is relatively complicated and thus Motorola has supplied a PTP Link

Estimator that calculates the radio propagation and reliability of NLOS links using the PTP

400 Series Bridge equipment.

7.5 Legal Disclaimer

IN NO EVENT SHALL MOTOROLA, INC. BE LIABLE FOR ANY INJURY TO ANY PERSONS

OR ANY DAMAGE CAUSED DURING THE INSTALLATION OF THE MOTOROLA PTP 400

SERIES PRODUCT.

7.6 Mounting the ODUs

The ODU mounting bracket is designed to ease installation by fixing the bracket to the pole

and then bringing the ODU into position using a single bolt fixing. The ODU should be

mounted using the following steps ensuring that the cable entry is at the bottom:

The ODU mounting bracket is designed to work with poles with diameters in the range 50mm

(2”) to 75mm (3”).

16.

Step 1: Mount the bracket to the pole. Step 2: Mate the unit to the bracket and

tighten the nut and bolt.

Pole diameters of 25mm (1”) to 50mm (2”) can be accommodated by inverting the back of the

bracket as shown in

Figure 16.

52

Figure 16 - Mounting to pole diameters 25mm (1”) to 50mm (2”)

When adjustment is complete tighten all bolts to 14Nm (11 lb ft).

Warning: Do not over tighten the bolts as bracket failure may occur.

The enclosure and mounting brackets of the PTP 400 Series Bridge are capable of

withstanding wind speeds up to 150mph (242kph). The installer should ensure that the

structure to which the bridge is fixed is also capable of withstanding the prevalent wind

speeds and loads. See Section

The integral safety loop should be used both for hoisting the ODU up a mast or building and

into position, and also as a fixing point to secure a permanent safety lanyard from the

tower/building to the ODU in case of mounting failure.

12 “Wind Loading”.

Figure 17 - Integral Safety Loop

53

The length of the safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard

should be made from a material that does not degrade in an outdoor environment.

The safety lanyard must be fixed to a separate fixing point that is not part of the direct

mounting system for the ODU.

7.7 Connecting Up

7.7.1 Preparing The Cable — RJ45 connections

Cables should be prepared using the following instructions along with the cable and

connector supplier’s instructions:

Step 1: Assemble gland Step on cable as

shown

Step 3: Arrange conductors as shown in

Figure 19 and cut to length

Step 2: Strip the outer insulation

Step 4: Insert conductors and crimp

54

Figure 18 - Completed ODU connector

Both ends of the ODU cable are terminated in the same way. The above procedure should be

repeated for the PIDU Plus end of the cable when the cable routing process is complete.

Note: The PIDU Plus end of the cable does not employ a cable gland.

Figure 19 - RJ45 Pin Connection

55

7.7.2 Making the Connection at the ODU

The following procedure describes how connection is made at the ODU. It is often easier to

carry out this procedure on the ground or a suitable surface prior to mounting the ODU.

Ensure no power is connected to the PIDU Plus or present on the cable before connecting

the ODU.

Step 1: Assemble the cable as described in

5.7.1 above

Step 2: Insert the RJ45 connector making

sure that the locking tab snaps home

Step 3: Screw in the body of the weather

proofing gland and tighten

Step 4: Screw on the clamping nut and

tighten

Figure 20 - Connections at the ODU

56

Should it be necessary to disconnect the PIDU Plus to ODU cable at the ODU this can be

achieved by removing the weather proofing gland and depressing the RJ45 locking tab with a

small screwdriver as shown below:

Figure 21 - Disconnecting the ODU

Warning: Ensure that power is removed from the system at the PIDU Plus to prevent damage

to the ODU while making or breaking the connection.

7.7.3 Routing the Cable

After connecting the cable to the ODU it can be routed and secured using standard cable

routing and securing techniques. When the cable is in place it can then be cut to the desired

length at the PIDU Plus prior to connection to the PIDU Plus.

7.7.4 Fitting a Surge Arrestor

If you have opted to fit a Surge Arrestor, this should be installed by following the

manufacturer’s instructions. For recommended types see Section

11 “Lightning Protection”

57

7.7.5 Grounding the Installation

The Outdoor Unit (ODU) for the PTP 400 Series Bridge must be properly grounded to protect

against power surges. It is the user’s responsibility to install the equipment in accordance with

Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the

Canadian Electrical Code or the National Electrical Code in the country of installation. These

codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in

wire and discharge unit, size of grounding conductors and connection requirements for

grounding electrodes. It is recommended that installation of the outdoor unit be contracted to

a professional installer. See Section

11 “Lightning Protection” for recommended grounding

kits. Failure to follow these Lightning Protection recommendations will invalidate your

warranty if damage to the system is found to be caused by lightning.

7.7.6 Making the ODU Connection at the PTP 400 Series Bridge PIDU Plus

The ODU is connected to the PIDU Plus by means of a concealed RJ45 connector. The RJ45

connection has been placed inside the PIDU Plus hinged cover to prevent the user

inadvertently plugging other equipment into the ODU RJ45 socket.

Warning: Plugging other equipment into the ODU RJ45 socket may damage the equipment

due to the non-standard techniques employed to inject DC power into the 100BaseT

connection between the PIDU Plus and ODU. Plugging the ODU into other equipment may

damage the ODU and/or the other equipment.

Step 1: Undo the retaining screw and hinge

back the cover.

Step 2: Plug in the ODU to PIDU Plus Cable

ensuring that it snaps home

58

Step 3: Replace the cover and secure with the retaining screw

7.7.7 Making the Network Connection at the PIDU Plus – PTP 400 Series

The Network connection is made by connecting the user’s Network Equipment directly to the

PIDU Plus LAN port as shown in

Figure 22 - Making the Network Connection at the PTP 400 Series Bridge PIDU Plus

Figure 22.

59

7.7.8 Mounting the PTP 400 Series Bridge PIDU Plus

Motorola recommends that you mount the PIDU Plus on a wall or other suitable mounting

surface. This prevents the unit from being knocked or kicked and can help maintain link

availability. Ensure that the reset switch can be accessed when mounting the unit.

Step 1: Fix the PIDU Plus to the wall using the lugs provided.

Step 2: Make connections as per Section

7.7.6

WARNING: The PIDU Plus is not waterproof and should be mounted away from sources of

moisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure,

preferably ventilated.

It is also recommended that you fit a drip loop on the PIDU Plus to ODU cable to ensure that

any moisture that runs down the cable into the cabinet or enclosure cannot enter the PIDU

Plus. As shown in

Figure 23. The network connection and mains cable should be treated in

the same way if there is a risk that they can carry moisture to the PIDU Plus.

60

Figure 23 - PTP 400 Series Bridge PIDU Plus Drip Loop Configuration

WARNING: It is possible for moisture to enter the cable due to damage to the outer protective

layer. This moisture can track down the inside of the cable, filling up the drip loop and

eventually finding its way into the PIDU Plus. To protect against this the outer protective layer

of the cable can be opened up at the bottom of the drip loop to allow this moisture to escape.

WARNING: Some network operators employ gel filled cables to get around the problem of

moisture ingress and transmission. The PTP 400 Series Bridge has NOT been tested using

these cables. Use of gel filled cables may affect the performance of PTP 400 Series Bridges.

The PTP 400 Series Bridge is supplied as a pair of matched Master/Slave units. The Master

unit to be configured can now be powered up and accessed using the default URL

http://169.254.1.2/ ; the Slave unit can be accessed using http://169.254.1.1/

Prior to powering up the PTP 400 Series Bridge, a computer with web browsing capabilities

should be configured with an IP address of 169.254.n.n and subnet mask of 255.255.0.0

where n is any value between 1 and 254 but excluding 1.1 or 1.2. If the default addresses of

the unit 169.254.1.1/2 clashes with an address you are already using on your LAN, or you are

not sure, you should set up an isolated LAN. As the LAN connection presented at the PIDU

Plus has a default configuration as a hub/switch (and auto-sensing MDI/MDIX cross over is

employed) connection can be made directly to the computer using a standard CAT 5 patch

cable.

Before physical installation takes place the units to be installed should be set up as described

in the section

address to one that is in the desired address range and set each unit up with the MAC

address of its peer unit ready to establish a radio link. It is recommended that this procedure

be carried out on the bench before physical installation commences. Providing it is safe to do

so the installer should take the process to the point where a radio link is established before

proceeding to the installation site.

NOTE: It is possible that some units may not be accessed using the above default URL. This

is because these units may have been previously configured with IP addresses 10.10.10.10

(Slave) and 10.10.10.11 (Master). Therefore, users must use the URL

and/or URL

browsing capabilities is configured with an IP address of 10.10.10.n, where n is any value

between 2 and 254 but excluding 10 and 11, to configure these units.

8.3.5. This process will give the installer the opportunity to set the unit’s IP

http://10.10.10.10/

http://10.10.10.11/ to configure the units. Please ensure that a computer with web

7.7.10 Aligning the PTP 400 Series ODUs

The following is a description of the steps taken to establish a radio link between the two

units forming the bridge and align the units for the best signal strength.

The PTP 400 Series Bridge uses audible tones during installation to assist the installer with

alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation

14

until highest pitch tone is achieved

. The tones and their meanings are as follows:

State Name Tone Description State Description Pitch Indication

(Higher pitch = higher
power)

Band Scan Regular beep Executing band scan N/A

Scanning Slow broken tone Not demodulating the

Rx Power

wanted signal

Synchronized Fast broken tone Demodulating the wanted

Rx Power

signal

Registered Solid tone Both Master and Slave

Rx Power
units exchanging Radio
layer MAC management
messages

Table 10 - Audio indications from the ODU

The term ‘wanted signal’ refers to that of the peer unit being installed.

In each of the states detailed above the unit should be aligned to give the highest pitch tone.

It should be noted that if, when in the Synchronized or Registered state the tone varies wildly,

you may be suffering from interference or a fast fading link. Installing in this situation may not

give a reliable link. The cause of the problem should be investigated.

For the ease of alignment both Master and Slave units use the install tones in the same way

but with some small behavioral differences. This allows the installer to install the Slave unit

first and carry out the initial alignment with the Master unit if desired. However due to the

Behavioral differences of Master and Slave units it is recommended that the Master unit is

installed first and the initial alignment carried out at the Slave unit.

The following behavior should be noted:

14

The pitch of the alignment tone is proportional to the power of the received wireless signals. The

best results are usually achieved by making small incremental movement in angular alignment.

63

When first started up and from time to time the Master unit will carry out a band scan to

determine which channels are not in use. During this time, between 10 and 15 seconds, the

Master unit will not transmit and as a consequence of this neither will the Slave unit. During

this time the installation tone on the master unit will drop back to the band scan state and the

Slave unit will drop back to Scanning state with the pitch of the tone set be the background

noise level. Alignment of the unit should cease during this time.

The master unit can take between 30 seconds in 0-5km (0-3 miles) mode to 300 seconds in

15

0-200km (0-124 miles) mode to determine the range of the link being installed

. The Master

unit will remain in the Scanning state until the range of the link has been established. The

Master unit will only move to the Synchronized state when the range of the link has been

established.

If at the end of the ranging period the ‘Registered’ state is not achieved due to interference or

other reasons, the Master unit will retry twice more on the same channel before moving to

another available channel. Should this occur it might take a number of minutes to establish a

link in the ‘Registered’ state.

The Slave unit does not have a ranging process. The slave unit will change to the

Synchronized state as soon as the wanted signal is demodulated.

When the alignment process is complete the installer MUST REMEMBER TO DISARM BOTH

UNITS in the link as described in section

8.3.5. This is necessary for the following:

• Turn off audible alignment aid.

• Enable Adaptive Modulation

• Fully enable Dynamic Frequency Selection

• Clear unwanted installation information from the various systems statistics

• Store the link range for fast link acquisition on link drop

• Enable Higher Data Rates

The units will automatically disarm after 24 hours.

15

If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging

behavior for the 400 Series Bridge may be affected. The Master has to monitor the initially chosen

channel for 60 seconds to make sure it is clear of radar signals before transmitting. If radar is

detected during any of the installation phases a further compulsory 60 seconds channel scan will take

place as the master unit attempts to locate a new channel that is free of radar interference.

8 Web Page Reference

The web user interface has three main sections. The home page presents to the operator a

high level summary of the PTP 400 Series Bridge point-to-point wireless link. The status page

presents a more detailed set of system parameters describing the performance of the

wireless link together with other key system performance metrics. The final section is the

system administrator section. This section is password protected and allows the system

administrator to perform all the day-to-day administrative procedures, e.g. software upgrades

and configuration changes.

The following subsections give a detailed usage guide for all the web user interfaces.

automatically display all sub options.

8.1 Home Page – PTP 400 Series Bridge

The home page for the PTP 400 Series Bridge has been designed to display a high level

summary of the status of the wireless link and associated equipment. The home page (

) normally displays four key system attributes:

25

Wireless Link Status: The Wireless Link Status attribute as the name suggests displays the

current status of the wireless link. A state of ‘Up’ on a green background indicates that a

point-to-point link is established. A state of ‘Down’ on a red background indicates that the

wireless link is not established. If the link is down for an unknown reason the system

administrator should first consult the status web page for a more detailed summary of up to

date system diagnostics.

Link Name: The link name attribute is a name and/or handle allocated by the system

administrator to aid the identification of the unit, network or building.

Figure

Figure 25 - PTP 400 Series Bridge Home Page

Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in days,

hours, minutes and seconds since the last system restart. The system can restart for several

reasons, e.g. commanded reboot from the system reboot webpage, or a power cycle of the

equipment.

System Clock: If the SNTP (Simple Network Time Protocol) (see section

system clock attribute is displayed giving the date and time of the last page refresh. If SNTP

is disabled then the system clock attribute is not displayed on the home page.

8.1.1 Home Page Alarm Display

The home page is also used to display all outstanding major system alarms. Whenever

system alarms are asserted, a yellow warning triangle is displayed on the web page

navigation bar. The warning triangle will be visible from all web pages. Clicking the warning

triangle will cause the web page to jump back to the system home page.

sample alarm screen.

Figure 26 shows a

Figure 26 - Alarm Warning Triangle

The following major system alarms are defined:

Install Arm State: The Install Arm State alarm is displayed. This alarm warns when a

wireless unit is in installation mode. After installation the wireless unit should be disarmed.

This will increase the wireless link’s data-carrying capacity and stop the installation tone

generator. The wireless link is disarmed from the ‘Installation Wizard’ see section

8.3.5.

67

Install Status: If any errors are detected during the installation process, the unit will

automatically raise an audible alarm. The install status alarm will be raised with an

appropriate reason code, e.g. the alarm will be raised if an incorrect target MAC address is

specified for the peer PTP 400 Series Bridge wireless unit.

ARQ Is Not Configured: ARQ must be enabled on both ends of the Point-to-Point link. This

error message is generated if there is a mismatch in the ARQ settings between both ends of

the link.

Encryption Is Not Configured On Both Units: Encryption must be enabled on both ends of

the Point-to-Point link before the over-the-air packets can be successfully decrypted. This

error message is generated if encryption is not configured on both units.

Ethernet Link Status: If there are any problems with the Ethernet interface this alarm will be

asserted. This alarm will most likely be seen if the unit has not got an Ethernet cable plugged

into its Ethernet socket.

Master And Slave Have Incompatible Region Codes: The PTP 400 Series Bridge uses

region codes to comply with local regulatory requirements governing the transmission of

wireless signals. Region codes can only be changed by obtaining a new PTP 400 Series

Bridge license key. If this alarm is encountered the appropriate license keys from the country

of operation should be obtained from your distributor. Applying license keys containing the

same region codes to both ends of the link will remove the alarm.

Spectrum Management Channel Warning: The alarm warns a user when the intelligent

spectrum management feature can't find a suitable wireless channel. This alarm occurs when

the signal assessment features of the PTP 400 Series Bridge can’t find a channel to operate

on.

Ethernet Configuration Mismatch: The detection of Ethernet fragments (runt packets) when

the link is in full duplex is an indication of an auto-negotiation or forced configuration

mismatch.

Wireless Link Disabled Warning: Wireless traffic has been disabled via the SNMP

ifAdminStatus attribute.

SNTP No Sync Warning: This warning indicates that SNTP has been enabled but that the

unit is unable to synchronize with the specified SNTP server. Section

8.3.13 explains how to

configure SNTP.

68

8.2 System Status Page

The status page has been designed to give the system administrator a detailed view of the

operation of the PTP 400 Series Bridge from both the wireless and network perspectives.

The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet.

The ‘Equipment’ section contains the entire unit’s inventory and identification information. The

“Wireless” section presents the key wireless metrics displayed as a series of measurements

and histograms. The ‘Ethernet/Internet’ section describes the unit’s network identity and

connectivity.

The status page can be configured to refresh itself at an operator defined rate (if the user is

logged in as system administrator). The refresh period defaults to 3600 seconds and can

easily be changed to refresh at any period between 2 seconds and 3600 seconds. Pressing

the ‘Update Page Refresh Period’ button causes a new page refresh period to be adopted by

the system. The page refresh mechanism uses a HTML Meta refresh command. Therefore

the refresh is always initiated by the local browser and not by the PTP 400 Series Bridge at

this interval.

Figure 27 - Status Page

The two PTP 400 Series Bridges are arranged in a master and slave relationship. The roles

of the units in this relationship are displayed in the page title. The master unit will always have

the title ‘- Master’, and the slave will always have the ‘- Slave’ appended to the ‘Systems

Status’ page title.

69

The following section details all the attributes displayed on the status page:

Link Name: The link name is allocated by the system administrator and is used to identify the

equipment on the network. The link name attribute is to a maximum size of 63 ASCII

characters.

Link Location: The link location is allocated by the system administrator and can be used as

a generic scratch pad to describe the location of the equipment or any other equipment

related notes. The link location attribute is limited to a maximum size of 63 ASCII characters.

Software Version: The attribute describes the version of software installed on the

equipment. The format of the attributes is FFPP-XX-YY where FF is the frequency variant
(4.9, 5.8 or 5.4 GHz), PP is the product variant, XX is the major release version and YY is the

minor release version.

Hardware Version: The hardware version attribute contains all the combined hardware
version information. The attribute is formatted as DX.-RYY-Z where DXX contain the version
of the digital card, RYY contains the version of the RF (radio frequency) card and Z describes

the antenna type which can be I (integrated) or C (connectorized).

Region Code: The region code is used by the system to constrain the wireless to operate

within the regulatory regime of the particular country. The region code is encoded in the

product license key. If the operator wishes to change the region code, a new license key must

be obtained from Motorola or the local distributor / system integrator.

Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in years,

days, hours, minutes and seconds since the last system restart. The system can restart for

several reasons, e.g. commanded reboot from the system reboot web page, or a power cycle

of the equipment.

Ethernet Link Status: Current status of the Ethernet link. A state of ‘Up’ with a green

background indicates that an Ethernet link is established. A state of ‘Down’ with a red

background indicates that the Ethernet link is not established.

Ethernet Speed: The negotiated speed of the Ethernet interface specified in Mbps.
Ethernet Duplex: The negotiated duplex of the Ethernet interface.
Full Duplex: Full Duplex data transmission means that data can be transmitted in both

directions on a signal carrier at the same time. For example, on a local area network with a

technology that has full duplex transmission; one workstation can be sending data on the line

while another workstation is receiving data.

70

Half Duplex: Half Duplex data transmission means that data can be transmitted in both

directions on a signal carrier, but not at the same time. For example, on a local area network

using a technology that has half duplex transmission, one workstation can send data on the

line and then immediately receive data on the line from the same direction in which data was

just transmitted.

MAC Address: The Medium Access Control Layer (MAC) address is used to uniquely

identify the equipment on an Ethernet network.

IP Address: Internet Protocol (IP) address. This address is used by the family of Internet

protocols to uniquely this identify the unit on a network

Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated

based on a network configuration. By organizing hosts into logical groups, subnetting can

improve network security and performance.

Gateway IP Address: The IP address of a computer on the current network that acts as a

gateway. A gateway acts as an entrance / exit to packets from / to other networks.

Wireless Link Status: As the attribute name suggests, this displays the current status of the

wireless link. A state of ‘Up’ on a green background indicates that a Point-to-Point link is

established. A state of ‘Down’ on a red background indicates that the wireless link is not

established. If the link is down for an unknown reason the system administrator should first

consult the status webpage for a more detailed summary of the prevailing system diagnostics.

Target Receive Modulation Mode: The target modulation mode is used by the wireless

subsystem to control the adaptive modulation algorithm. The mode is used by the PTP 400

Series Bridge as an upper limit. The system will not move to a high rate modulation mode

even if the signal / interference environment will support high rate modes.

Maximum Transmit Power: The maximum Transmit Power the local wireless unit is

permitted to use to sustain a link.

Remote Transmit Maximum Power: The maximum transmit power the remote wireless unit

is permitted to use to sustain a link.

71

Transmit Power: Transmit power histogram

17

is expressed in dBm and presented as: max,

mean, min, and latest.

Receive Power: Receive power histogram is expressed in dBm and presented as: max,

mean, min, and latest.

Vector Error: The vector error measurement compares the received signal’s In phase /

Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite error

vector magnitude. The results are stored in a histogram and expressed in dB and presented

as: max, mean, min and latest. The expected range for Vector Error would be approximately

0dB (NLOS link operating at sensitivity limit on BPSK ½) to –29dB (short LOS link running

64QAM 7/8).

Link Loss: The link loss is the total attenuation of the wireless signal between the two

point-to-point units.

17

All histograms are calculated over a one hour period. If the equipment has been running for

less than one hour then the histograms are calculated over the current elapsed time.

The data used to compute the histogram statistics can be downloaded in an ASCII comma

separated value (CSV) format via the diagnostics CSV Download page, see section 8.3.14

Receive Modulation Mode: The modulation mode currently being used on the receive

channel. The number in brackets after the modulation mode and coding rate string is the

effective data rate available to all MAC layer protocols.

Transmit Modulation Mode: The modulation mode currently being used on the transmit

channel. The number in brackets after the modulation mode and coding rate string is the

effective data rate available to all MAC layer protocols.

Receive Modulation Mode Detail: The receive modulation mode detail presents to the user

the reason why the wireless link is not operating at the maximum capacity (modulation mode).

Values that can be presented in this field are:

73

• Running at maximum receive mode:

The wireless link is operating at its receive maximum capacity. To confirm that the

wireless link is operating at its maximum transmit capacity either look at the 'Transmit

Modulation Mode' on this page or look at the peer wireless units 'Receive Modulation

Mode Detail' attribute.

• Running at user-configured Target Modulation Mode:

This indicates that the wireless link could operate at a higher capacity but has been

limited in modulation mode by the user from the configuration page.

• Restricted because Installation is armed:

During installation the wireless link is restricted to operate in a low order modulation

mode (BPSK ½ ). Disarming the wireless units after installation will allow the wireless link

to adaptively select its own operational modulation mode.

• Restricted because of byte errors on the wireless link:

During normal operation the wireless link monitors its performance. If byte errors are

detected during normal data transmission / reception the wireless unit automatically

changes the active modulation mode to a more robust mode in order to reduce the

number of errors.

• Restricted because a DFS channel change is in progress:

During Spectrum Management (DFS) channel changes the wireless unit temporarily

reduces the modulation mode to BPSK ½.

• Restricted due to the low Ethernet link speed:

If the Ethernet link speed is less that the instantaneous wireless link capacity then the

modulation mode is optimized so that the Ethernet link speed is satisfied using the most

robust modulation mode.

• Limited by the wireless conditions:

The wireless link capacity is limited by the current wireless conditions e.g. interference,

excess path loss, etc…

admin password is not set. Simply click the login button to access the system administration

features. Once the password has been set using the ‘Change Password’ menu item, the

system administration pages will only be available after the user has entered the correct

password.

75

8.3.1 System Configuration Page

The configuration page (

400 Series Bridge.

Figure 29) is used by the system administrator to configure the PTP

Figure 29 - Configuration Page

While the majority of the system configuration is entered during installation and should never

require changing, this page offers the system administrator the ability to change the basic

system parameters for link, modulation and physical components.

Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used to describe the location of the equipment or any other

equipment related notes (max 63 characters).

Master Slave Mode: The Master unit is the controlling unit with respect to the point-to-point

link and its maintenance. The master transmits until the link is made, while the Slave listens

for its peer and only transmits when the peer has been identified.

76

Link Mode Optimization: By default, Link Mode Optimization of a point-to-point link is set to

‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by

automatically adapting the active modulation mode based on instantaneous vector error

measurements and the presence of codeword errors. This mode of operation is

recommended for connection oriented IP traffic protocols where packet loss is perceived by

the protocols as an indication of network congestion. It is recommended that when using this

mode of operation the ARQ state is set to ‘enabled’. The ‘TDM Traffic’ mode is recommended

for E1 / T1 applications and connectionless oriented protocols. In this mode the wireless link

is optimized for minimum transmission latency and preservation of data throughput by

allowing the link to maintain a higher modulation mode in the presence of a limited number of

codeword errors. It is recommended that when operating the link in TDM mode that the ARQ

state is set to disabled and that the Spectrum Management controls are used to fix the

wireless link to a single frequency. This can be achieved by using the installation wizard to

configure single frequency operation. In either case, a system reboot will be required.

Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate

(1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving

is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link

Master will spend twice as long transmitting as receiving. It should be noted that the data rate

available to the end users might not follow these ratios exactly. The exact data rates will be

dependant on the prevailing modulation modes.

Throughput Optimization: Throughput Optimization has two distinct modes:

• Data Throughput configures the wireless link for maximum data throughput.

• Low Latency configures the wireless link to minimize packet latency during transmission

over the wireless link. When Low Latency mode is selected, the Link Symmetry is

automatically reconfigured to a symmetric link. Link asymmetry is not supported in Low

Latency mode.

Note: The “Throughput Optimization" option is not available on 4.9GHz variants.
ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to

transmission errors over the wireless link are retransmitted rapidly. The retransmission helps

to prevent TCP congestion mechanisms from inadvertently interpreting intermittent packet

loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it

to function.

77

Target Receive Modulation Mode: This is the maximum mode the unit will use as its

adaptive modulation. The modulation modes available are:

• BPSK 1 / 2

• QPSK 1 / 2

• QPSK 2 / 3

• 16QAM 1 / 2

• 16QAM 3 / 4

• 64QAM 2 / 3

• 64QAM 3 / 4

• 64QAM 7 / 8

By default the Target Receive Modulation Mode is 64QAM 7/8. The value in brackets shows

the maximum unidirectional data for the current modulation / ranging mode combination.

Maximum Transmit Power: This specifies the maximum transmit power in dBm of the

system, it is country dependent and although the user can change this it will be limited to that

country’s regulations.

Ethernet Compression: When Ethernet compression is enabled all compressible Ethernet

packets are transmitted over the wireless link using a compressed data format. This will have

the net effect of increasing wireless link traffic throughput. Because the compression

techniques used in the PTP 400 Series Bridge are CPU intensive, compression is only

applied to modulation modes BPSK 1/2, QPSK 1/2 and QPSK 2/3. The net effect of

compression is solely dependant on the individual packet compressibility (entropy). Random

data will not produce good packet compression; however ASCII text and other non-random

data sources will produce an acceptable level of compressibility.

All the above attributes are non-volatile. Once set they will be used by the unit even after a

power-on reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP

Address will require a reboot before they are used. If any of these attributes are changed a

reboot screen appears asking the user to verify the reboot. (See

Figure 30)

Figure 30 - Configuration Reboot Page

78

Note: At this point you will lose connection to the unit. If you have just changed the IP

Address you now have to reconnect to the unit using the address just set.

8.3.2 LAN Configuration Page

The LAN Configuration page (

Figure 31) is used by the system administrator to configure the

network parameters for the PTP 400 Series Bridge.

Figure 31 - LAN Configuration Page

IP Address: Internet protocol (IP) address. This address is used by the family of Internet

protocols to uniquely identify this unit on a network.

Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated

based on a network configuration. By organizing hosts into logical groups, subnetting can

improve network security and performance.

Gateway IP Address: The IP address of a computer / router on the current network that acts

as a gateway. A gateway acts as an entrance / exit to packets from / to other networks.

VLAN High Priority Traffic Threshold: If enabled, this sets the 802.1p VLAN user priority

threshold at which bridged traffic will be treated as high-priority.

79

Use VLAN for Management Interfaces: If enabled, this allows the use of VLAN for

Management Interfaces. Selecting this option presents the user with extra fields in which to

enter the management VLAN ID, Priority and whether to validate the VLAN ID. The following

warning message window is displayed when this option is enabled:

Figure 32 - VLAN Warning Window

After clicking on OK, the following VLAN options are added to the LAN Configuration window:

Figure 33 - Additional VLAN options

80

These parameters control whether the management interfaces (HTTP/SNMP/SMTP/SNTP)

use a VLAN. Selecting this option presents the user with extra fields in which to enter the

Management VLAN ID, Priority and whether to validate the VLAN ID.

If communication with the unit is lost due to mis-configuration or the user forgot the VID that

has been set. The unit can be recovered by resetting the unit to factory defaults as described

in Section

Note: The internal Ethernet stack used to manage a unit does not support double VLAN

tagged packets. Double VLAN tagged packets will be discarded.

Note: If you lose contact with your unit due to mis-configuration you will need to reset your

unit to factory default as described in Section

3.3.2 “The Power Indoor Unit - PIDU Plus”

Ethernet Configuration: This enables the Ethernet configuration to be forced rather than

auto negotiated. The configuration should only be forced if you are having problems with auto

negotiation. You must ensure that you configure both this unit and the Ethernet port to which

it is connected identically. If you force a fixed Ethernet Configuration on the PTP 400 Series

Bridge, then you MUST also force the same fixed configuration on the equipment to which it

is connected. If you fail to force the configuration of the connected equipment, its automatic

configuration mechanisms will normally cause a duplex mismatch, and you will receive greatly

reduced throughput!

Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface

(MDI)/Medium Dependent Interface Crossover (MDIX) capability.

Drop Ethernet Link On Wireless Link Down: When enabled, this causes the Ethernet link

to be dropped briefly when the Wireless link drops. This is so that spanning tree algorithms

can quickly detect that there is a problem

Local Packet Filtering: When Local Packet Filtering is Enabled, the bridge learns the source

MAC addresses of devices transmitting Ethernet packets on the local Ethernet network, and

only bridges packets to the remote unit if the destination MAC address has not been learned

as a 'local' device. When Local Packet Filtering is Disabled the bridge does not learn the

source MAC addresses of devices transmitting Ethernet packets on the local Ethernet

network, and bridges ALL Ethernet packets received to the remote unit. Local Packet Filtering

should be enabled when no external switching/routing hardware is present.

81

8.3.3 Save and Restore Menu

The save and restore feature of a PTP 400 Series bridge allows the system administrator to

backup the operation configuration of the wireless unit. It is recommended that this facility is

used immediately after a successful PTP 400 Series bridge installation or prior to any

software upgrade. In the unlikely event that a unit has to be replaced in the field, the

replacement unit can be reconfigured by simply playing back the saved configuration file.

To save the configuration file click on the ‘Save Configuration File’ button (

Figure 34 and

Figure 35) and save the configuration file (.cfg) to the hard drive of your computer20, 21.

WARNING: The configuration file is currently restricted to a single software version and can

only be restored into a wireless unit operating the software version indicated in the

configuration file header.

The configuration file can also be used when swapping out a faulty wireless unit. If one of the

wireless units is replaced on a wireless link a configuration file captured from the faulty unit

can be replaced into the new unit to speed up replacement. It should be noted that when

placing a configuration file into a wireless unit with a different MAC Address the license key

will not be restored and may need to be entered. This can be obtained either from the Quick

Install guide supplied with replacement wireless unit or directly from Motorola. Please note

that the target MAC address at the other end will also need to change.

84

The restoration of configuration files can be performed using the Restore configuration tool.

Using the browser button to locate the configuration file you wish to restore then click the

‘Restore Configuration File and Reboot’ button (

confirm the action (

Figure 38 - Reset Configuration and Reboot Confirmation Pop-up

On confirmation the PTP 400 Series bridge will:

o Upload the configuration file
o Perform data integrity checking
o Erase previous configuration
o Apply the new configuration
o Restart

After the unit has restarted the entire configuration from the configuration file will now be

active. Note: The IP address of the unit may have also been changed. The user can check

the new IP address by reading the header of the configuration file,

Wireless Good Tx Packets: Total number of good packets the bridge has sent for

22

transmission by the wireless interface

.

Wireless Good Rx Packets: Total number of good packets the bridge has received from the

wireless interface (see note

22).

Packets To Internal Stack: This displays the total number of good packets the bridge has

transmitted to the internal stack (e.g. ARP requests, PING requests, HTTP requests). See

22.

note

Packets From Internal Stack: This displays the total number of good packets the bridge has

received from the internal stack (e.g. ARP responses, PING replies, HTTP responses). See

22.

note

Ethernet Rx Fragments: Total number of short frames (<64 bytes, sometimes called runts)

received from the local Ethernet interface. On a half-duplex link, these packets are the result

of collisions and are to be expected. If you have forced the Ethernet configuration to full-

duplex and are getting such packets then you probably have a duplex mismatch (the device

you have connected is running in half-duplex). See note

22.

L2 Source Mac Address Conflicts: The number of times a packet received over the

wireless link had the Layer 2 (Ethernet) Source MAC Addresses of a device that had

previously been transmitting on the 'local' Ethernet network. This could indicate the presence

of a traffic loop or of L2 MAC Address spoofing on the network. See note

22.

ARQ Retransmitted Rx Packets: Total number of ARQ retransmitted packets that have

been received. See note

22.

Transmit Data Rate: The data rate in the transmit direction, expressed in Mbps and

presented as: max, mean, min, and latest histogram format. (See note

17)

The histogram is calculated over a one hour period. If the equipment has been running for

less than one hour then the histogram is calculated over the current elapsed time.

Receive Data Rate: The data rate in the receive direction, expressed in Mbps and presented

as: max, mean, min, and latest histogram format. See note

22.

Aggregate Data Rate: The aggregate data rate, expressed in Mbps and presented as: max,

mean, min, and latest histogram format. See note

Transmit Modulation Mode: Current active transmit modulation mode.
Receive Modulation Mode: Current active receive modulation mode.
Signal Strength Ratio: The Signal Strength Ratio, is the ratio of the power received by the

Vertical / Horizontal receivers.

Wireless Link Availability: Expresses the link availability as a percentage of time since the

first successful registration after a system restart. It is expressed as a percentage to four

decimal places.

Code Word Error Ratio: The ratio of detected codeword errors to the total number of

codewords since the last system counter reset.

PHY Code Word Error Counter: The wireless link uses error correction techniques to enable

reconstruction of packets where there is a certain level of data corruption. This counter

displays the total number of packets that were so badly corrupted that they could not be

reconstructed. See note

22.

Elapsed Time Indicator: Elapsed Time Indicator is the time in days, hours, minutes and

seconds since the wireless unit was last rebooted.

Statistics Page Refresh Period: The statistics page refreshes automatically according to the

setting entered here (in seconds).

The two buttons described below are also displayed:

8.3.5 Install Wizard Pages

These pages are used during system installation. There follows a description of the install

pages along with their use during the installation configuration process. The actual installation

process is described in section

7.7.10 “Aligning the ODUs”.

All wireless links are shipped as paired units. They are pre-configured at the factory so that

they can be installed without the user supplying any configuration. Each wireless link is

shipped with a Quick Start Guide. Attached to the Quick Start Guide is a summary of the

default configuration data.

Table 11 shows a sample link configuration. The values highlighted

have been committed to the wireless units non-volatile storage.

Example PTP 400 Series Bridge Configuration Data

Table 11 - PTP 400 Series Bridge Factory Configuration Values

The factory default configuration is written to the ‘semi-permanent’ configuration bank.

WARNING: The factory default configuration is limited in range to 40 Km (25 miles). If you

wish to install a wireless link, with a range of > 40 Km (> 25 miles) and < 200 Km (< 124

miles), you must follow the ‘

Manually Configuring the Wireless Units’ in section 8.3.5.1.

93

8.3.5.1 Manually Configuring the Wireless Units

If the installer / system administrator wishes, they may modify the default installation

configuration. If only the IP addresses are incorrect it is recommended that the values are

changed via the configuration menu (Section

modification then it is recommended that the system administrator use the Installation Wizard.

The operational software for the PTP 400 Series Bridge requires a license key to enable the

wireless bridging capability and program region code specific parameters in to the unit.

Please refer to Section

8.3.18 for more information on how to enter and validate a license key

into the unit.

8.3.5.2 Internet Protocol Configuration

Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP)

configuration.

8.3.1). If any other parameters require

Figure 41 - Installation Wizard Internet Protocol Configuration.

94

IP Address: Internet protocol (IP) address. This address is used by the family of Internet

protocols to uniquely identify this unit on a network.

Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated

based on a network configuration. By organizing hosts into logical groups, subnetting can

improve network security and performance.

Gateway IP Address: The IP address of a computer / router on the current network that acts

as a gateway. A gateway acts as an entrance / exit to packets from / to other networks.

Use VLAN Management Interface: This controls whether the management interfaces

(HTTP/SNMP/SMTP/SNTP) use a VLAN. Selecting this option first presents the user with the

warning box shown in

Figure 42, then presents the user with extra fields in which to enter the

Management VLAN ID, Priority and whether to validate the VLAN ID, as shown in

Figure 42 - VLAN Warning

Figure 43.

95

Figure 43 - Additional VLAN Management Options

Once complete click the ‘Submit Internet Protocol Configuration’ button or the ‘Next’ link.

Note: The internal Ethernet stack used to manage a unit does not support double VLAN

tagged packets. Double VLAN tagged packets will be discarded.

Note: If you lose contact with your unit due to mis-configuration you will need to reset your

unit to factory default as described in Section

3.3.2 “The Power Indoor Unit - PIDU Plus”

96

8.3.5.3 Wireless Configuration

A discussion of the wireless configuration and its relationship to the band of operations is

contained in section

5 “General Considerations”. It is recommended that the installer reads

this section before commencing with the product installation.

Step 2 of the installation wizard requires the installer to enter the wireless configuration

parameters:

Figure 44 - Installation Wizard Wireless Configuration

Target MAC Address: This is the MAC Address of the peer unit that will be at the other end

of the wireless link. This is used by the system to ensure the unit establishes a wireless link to

the correct peer.

The MAC Address can be found embedded within the serial number of the unit. The last six

characters of the serial number are the last three bytes of the unit’s MAC address.

Note: A PTP 400 Series system is shipped as a pair of units with pre-loaded correct MAC

addresses. MAC addresses will only need to be entered if an existing unit has to be replaced

in the field or the units configuration has been erased.

97

Master Slave Mode: At this point it is necessary to decide which end will be designated as

Master. The Master unit is the controlling unit with respect to the point-to-point link and its

maintenance. The master transmits until the link is made, while the Slave listens for its peer

and only transmits when the peer has been identified.

Link Mode Optimization: By default Link Mode Optimization of a point-to-point link is set to

‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by

automatically adapting the active modulation mode based on instantaneous vector error

measurements and / or the presence of codeword errors. This mode of operation is

recommended for connection oriented IP traffic protocols where packet loss is perceived by

the protocols as an indication of network congestion. It is recommended that when using this

mode of operation that the ARQ state is set to enabled. The ‘TDM Traffic’ mode of link

optimization is recommended for T1 / E1 applications and non-connection oriented protocols.

In this mode the wireless link is optimized for minimum transmission latency and preservation

of data throughput by allowing the link to maintain a higher modulation mode in the presence

of a limited number of codeword errors. It is recommended that when operating the link in

TDM mode that both ARQ state is set to disabled and the Spectrum Management controls

are used to fix the wireless link to a single frequency. This can be achieved by using the

installation wizard to configure single frequency operation (system reboot will be required) or

by using the Spectrum Management channel barring (a system reboot will not be required).

Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate

(1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving

is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link

Master will spend twice as long transmitting as receiving. It should be noted that the data rate

available to the end users might not follow these ratios exactly. The exact data rates will be

dependant on the prevailing modulation. If the direction you want to install the link asymmetry

is not achievable in the current configuration then the master and slave modes of both PTP

400 Series Bridges will need to be reversed.

Throughput Optimization: Throughput Optimization has two distinct modes:

• Data Throughput configures the wireless link for maximum data throughput.

• Latency Optimized configures the wireless link to minimize packet latency during

transmission over the wireless link.

Note: The Throughput Optimization option is not available on 4.9GHz variants.
