About the GE MDS Intrepid-HC HP OCBs

GE MDS Intrepid-HC HP RFUs and OCBs (Outdoor Circulator Blocks) can be chained in different ways for different configurations.

Two types of OCBs can be used:

Type1 OCB Type2 OCB

The main difference between the tw o types are the cir culator directions. Depending on the configur ation, OCB Type 1 or Type 2 are used together with waveguide shorts, waveguide loads, U Bends, C Bends, or couplers.

Each OCB has four waveguide access points: two in the front, and two at the rear. The diversity access point is optional.

If the system is not configured f or diversity, all the relevant access points on the OCB must be terminated using waveguide shorts

Chapter 2: Initial System Setup

General

After the system is installe d and tested, and antenna alignment is performed, the next step is initial IDU setup and configuration.

Initial setup proce dures are performed on a craft terminal via a serial port connection.

Note:

Configuration proc edures are generally performed using the NMS software supplied with MDS Intrepid-HC HP. A description of the NMS and how to use it is provided in the NMS User Guide. The craft terminal should be used only to perform the initial setup procedures describe d in this chapter. Once the

system is up and running, use NMS to maintain and operate the system on a regular basis.

Initial Setup Steps

The initial MDS Intrepid-HC HP setup proce dure includes the following steps:

Procedures Performed using a Craft Terminal:

- Connecting to the IDU via the terminal port

- Defining IP addresses

- Setup Options

Procedur es Perfo r m ed using th e N M S:

- Connecting to the Ethernet port

- Installing the software

- Setting the local TX frequency channe l

- Specifying system information

- Configuring the local/rem ote transport

- Configuring trap forwarding

MDS Intrepid-HC HP Installation and Operation 2-1

- Setting up external alarms

Connecting the Line Interfaces

Initial Setup using the Craft Terminal

The following procedures a re performed after the RFU and antenna are installed.

Con necting to the ID U via Serial Port

Turn the IDU power switch ON.

On the front panel of the IDU, the DRWR LED should be lit green. To set up the HyperTerminal connection:

1. Connect the RS-232 port of your computer to the RS-232 (9-pin) port on the IDU front panel. This port is labeled “Termina l”.

2. Select Start, Prog rams, Accesso ries , Co m m unica ti on, HyperTer minal.

3. Double-click the HyperTerminal application icon.

4. For Conne ctio n Description , type Terminal, and click OK.

5. In the Connect Using field (Pho n e Number), select Direct t o Com 1, and click OK.

6. In the Port Settings tab (Com 1 Properties), specify the following settings: Bits per second - 19,200

Data bits - 8 Parity - None Stop bits - 1 Flow control - Hardware

7. Click OK.

8. After you connect to the terminal, to enter the terminal setup program, press Enter.

9. For password, use admin.

2-2 MDS Intrepid-HC HP Installation and Operation

Defining IP Addresses

Before you can configure the MDS Intrepid-HC HP system, you need to define IP addresse s using the craft terminal.

The MDS Intrepid-HC HP includes two IP interfaces: an Ethernet interface, and a serial interface. Each interface has its own IP address and IP mask.

The IP address is a four digit number separa ted by decimal points. Each IP address is a pair netid,hostid, where netid identifies a ne twork, and hostid identifies a host on the network. The IP mask separates between the netid and hostid.

For example, if the IP address is 192. 114.35.12 (11000000 01110010 00100011 00001100), and the IP mask is

255.255.255.0 (11111111 11111111 11111111 00000000), the netid is 192.114.35, and the hostid is 12.

An IP interface can only communicate with hosts that are on the same net (have the same netid). In the example above, the interface ca n communicate only with hosts that have netid 192.114.35 (for 1 to 255).

If The transceiver ha s a frame to send to a host that is not on the Etherne t IP netid or the ser ial IP netid, the frame should be sent to an intelligent de vice (usually a gateway) on the network. Such a device, known as a "default router", will know how to send the frame over the internet. The default gateway should be a host on one of the Transceiver inter face netids.

The following figure shows how the tra nsceiver is integrated in the local network.

GE MDS Intrepid-HC HP Installation Guide 2-3

To define IP Addresses:

1. In the main terminal program menu, select Configuration.

2. Select IDC.

3. Select Basic.

4. Select IP and define the addresses as described above.

Important

After you set up IP addresses, restart the IDU to activate the m.

Setup Options in the Terminal Pr ogr am

The main menu in the terminal setup program includes the following options: Configuration (1) - the main setup section in whic h you can configure the IDC, the right and left drawers,

protection, SNMP management, in- band routing, and other such parameters.

System Stat us (2) - used to obtain information about the different software versions currently used in the system. Maintenance (3) - used to perform software upload, download, and reset. Diagnostics (4) - used to perf orm loopbacks a nd obtain system information. Logs (5) - used to view alarm and configuration log reports.

2-4 MDS Intrepid-HC HP Installation and Operation

Additional Setup Using the NMS

Some of the initial setup proce dures require the use of The NMS.

Once initial setup is complete , use The NMS to run the system on a daily basis.

Connecting to the Ethernet Port

1. Connect a crossed Ethernet cable from your PC to the Ethernet Port. If the connection is to a LAN (wall

connection) use the standa rd Ethernet cable.

2. Make sure the IP address on your PC is on the same sub-net as you defined in the MDS Intrepid-HC HP indoor unit (in most cases, the first three numbers of the IP address must be identical, depending on the sub-net mask).

NMS PC Requirements

Before you install the NMS software, verify that your PC has the following minimum requirements:

For Windows

Processor: Pentium 4, 2.8 GHz (minimum) Memory (RAM): 256 MB minimum Operating System: Windows 2000 or above Serial Port: RS-232 (Hyper-Terminal)

For UNIX

2. Select System configuration.

3. Select Cluster configuration.

Specify the number of sub-racks in the system . 1 f or stand alone, or 2 for cascading mode. Specify either 1 or 2 for the sub-rack number. The protecte d carrier will be in sub-rack 1.

2-14 MDS Intrepid-HC HP Installation and Operation

Defining IP Addresses

Before you can configure the Intr epid-HC HP/T system, you need to define four IP addresses using the craft terminal.

The Intrepid-HC HP/T includes thr ee levels of two IP interfaces: an Ethernet interface, and a serial interface. Each interface has its own IP addre ss and IP mask.

You must configure an IP address for each of the three IDCs - a unique shelf number for each she lf in the cluster. In addition, you must define same base IP address for every Intrepid-HC HP/T IDC. The address is a four digit

number separated by decimal points. Each IP address is a pair netid-hostid, where netid identifies a network, and hostid identifies a host on the ne twork. The IP mask separates between the netid and hostid.

For example, if the IP address is 192. 114.35.12 (11000000 01110010 00100011 00001100), and the IP mask is

255.255.255.0 (11111111 11111111 11111111 00000000), the netid is 192.114.35, and the hostid is 12.

If Intrepid-HC HP/T has a frame to send to a host that is not on the Ethernet IP netid or the serial IP netid, the frame should be sent to an intelligent de vice (usually a gateway) on the network. Such a device, known as a "default router", will know how to send the frame over the internet. The default gateway should be a host on one of the Intrepid-HC HP/T interface netids.

The Intrepid-HC HP/T cluster is manage d as a single Network Element (NE) by the EMS.

GE MDS Intrepid-HC HP Installation Guide 2-15

The following figure illustr ates an Intrepid-HC HP/T management model from an EMS/NMS point of view.

Each IDC calculates its own IP address, considering cascade shelf# and floor#: where:

##*3 floorshelfIPbaseIP ++=

IPbase is dividable by 8 (i.e. = IPbase & 0xfffffff8), shelf# = 0, which is the cascade master (the one with the pr otected carrier), or 1 for cascade slave, floor# = 1, 2, or 3 (the number of the floor within the Intrepid-HC HP/T shelf).

In-band Management

In-band management of the Intrepid-HC HP/T link chain must be configured carefully due to a large number of public IP address alloc ations. In addition, it should be noted that in-band mana gement becomes a limiting factor for chain length when only the Class C DCN is used.

The figure below illustrate s the largest Class C in-band subnet (with CIDR = 26 bits, i.e. subnet mask

255.255.255.192).

The DCN shown in the figure makes use of the 192.168.1.64 in-band subnet. This subnet allows 62 nodes

192.168.1.65 - 192.168.1.126, and has a broadcast address of 192.168.1.127.

It is assumed that the Intrepid-H C HP/T at site A has a single GNE 1 assigned to one of the IDCs.

All three IDCs at site A have direct out-of - band IP connectivity with remote management applications (NMS, SNMP Agent, Telnet). The remaining Intrepid-HC HP/T chain IP addresses are accessed via the GNE IDC.

2-16 MDS Intrepid-HC HP Installation and Operation

Note that the Inband bytes run through the uppe r level of the cluster.

The Ethernet interfa ce of every Ne twork Element (NE) is assigned the CIDR=/29 subnet, i.e. subnet mask

255.255.255.248. This allows 6 elements to be communicated over the interface. These addresse s can be fully utilized when two Intre pid-HC HP/T shelves are cascaded for 7+1 group protection.

The figure above shows “back-to-back” connected Intrepid-HC HP/T shelves at the same sites: B, C, and D, for East/West chaining. Two NE IDCs (NE 2 and NE 3), at the same site, are connected over a PPPoE link.

This scheme allows four links of up to 7+1 (eight Intrepid-HC HP/T shelves, as shown, or sixteen shelves cascade d in pairs) chaine d through the same NMS/SNMP Agent management, when IP addresses are allocated as described above.

Notes:

1. The CIDR=/29 subnet allows externa l element communication (such as a laptop connected to the site B LAN) only if there are less than six IDCs opera ting on two cascade d Intrepid-HC HP/T sufficient for three Intr epid-HC HP/T

cascading shelves. Three cascaded shelves require CIDR=/28 nodes

shelves. The subnet is not

(subnet mask 255.255.255.240). This reduces the available number of chained links to 50%.

GE MDS Intrepid-HC HP Installation Guide 2-17

2. High protocol timing constraints (SNMP/TFTP) are expected in Intrepid-HC HP/T link chains due to the large number of hops (each East/West site adds two in-band routing hops), and a large number of managed IDC nodes.

The following slight optimiz ation may be useful for a chain topology (but not for a ring): One of the in-band NE management channels is configure d as a Default GNE Direction, assuming the channel

leads to the nearest GNE under normal conditions. Then, in-band routing chooses this channel as a first prior ity for every “in-band packet” generated internally, or received fr om the Ethernet interface.

To define IP Addresses:

1. In the main terminal program menu, select Configuration.

2. Select System configuration.

3. Select IDC configuration.

4. Select IDC Basic configuration.

5. Select IP.

4. Select Protectio n E na bl ed .

5. Select Switch On Earl y Warning if you want the switch to occur when the system reaches an MSE of -28.

6. For Revertive Link, select the carrier that will be connected to the +1 modem. Your selection will be used in cases where a switch occurs and then the system re turns to normal operation.

Examples Revertive = Extra Traffic

If a major alarm occurs at site A, a request is sent to site B to transmit through the Extra Traffic channel. The switch that is performe d is Hitless (up to 10 ms), a nd the Extra Traffic channel will no longer exist on both sides by definition (gene rally, the system can protect up to two faults at different sides). The moment the alarm is cleared, the +1 (Extra Traff ic) modem will refer to the input from the +1 MUX.

Revertive = None

Each carrier MUX will receive two inputs: its own modem, and the +1 modem. The Extra Traffic channel will not exist. Data to the MUX (for each of the defined carriers) will be received from its own modem until the

GE MDS Intrepid-HC HP Installation Guide 2-25

first hitless fault. When the fault is cleared, the MUX will receive data from two sources: the +1 modem, and its own modem, meaning the next fault in this channel will be errorless (if other carriers will fail, the da ta will be hitless).

Revertive = Carrier#X

MUX number X will always receive two sources: the +1, and its own, unless there is a fault in another carrier. If MUX number X receives two sources, and a fault occurs, the switch is errorle ss. I n all the other cases, the switch is hitless.

7. For Revertive Switch Timeout, specify the period (in seconds) after which the revertive mode will be

activated.

8. For High Pri ori ty Thr es hol d , click the drop-down list and select the criteria upon which the system will

perform a switch to the channel you chose as high priority. The options include: Base band Loss of Frame, Baseband Excessive BER, Baseband Signal Degrade, and Early

Warning

9. In the priority table, designate the high priority channel(s) . A high priority channel will be switched first when the criteria chose n for the threshold is met, even if a major fault occurs in a different channel.

The Priority Level options include :

Normal - regular operation acc ording to the N+1 mechanism High Priority Not Protected – stand-a lone channel without protection

Site Acceptance Checklist Notes

The following notes provide im portant additional information about the Site Acceptance Checklist.

1. Antenna Mounting

Mounting pole is of sufficient he ight to clear local obstructions, such as parapets, window cleaning

gantries, and lift housings.

Mounting Pole is of sufficie nt height, and is safely positioned, so as not to cause a safety hazard. No

person should be able to walk in front of, or look directly into the path of the microwave radio beam. Where possible, the pole should be away from the edge of the building.

Mounting pole is secure and perpe ndicular. A pole that is not perpendicular may cause problems during

antenna alignment.

Mounting pole is grounded as per site spec ifications. All operators and site owners have specif ic

requirements re garding the grounding of installations. As a minimum, typica l requirements are such that any metal structure must be connected to the existing lightning protection ground of the building. Where it extends beyond the 45-degre e cone of protection of existing lightning conductors, additional lightning protectors should be insta lled.

All steelwork is Galvaniz ed or Stainless Steel, as appropriate to prevent corrosion.

MDS Intrepid-HC HP Installation and Operation

3-5

2. Antenna

Antenna is grounded as per site spec ifications. See the third point in the Antenna Mounting section above. Antenna sway braces are fitted and insta lled correctly, where applicable . Typic ally, for an antenna of 1.2

m or larger, an extra sway brace is fitted to the mounting fr ame of the ante nna. This sway brace should not be mounted to the same pole as the antenna, but should be installed dir ectly back to the tower or an alternative point.

Antenna Water Drain Plugs are fitted a nd removed, where appropr iate. Some antennas have moisture

drain plugs installed at va rious points around the antenna. The purpose of these plugs is to allow any moisture that forms on the inside of the a ntenna or radome to drip out and prevent a pool within the antenna. Only the plugs at the bottom of the antenna, after installation, should be remove d. All othe r plugs should be left in position.

3. RFU (RF Unit)

The RFU is grounded as per installation instruc tions. See the third point in the Antenna Mounting section

above.

The RFU Polarization is as per link requir ements and matches the polarization of the antenna.

4. Indoor Unit

The main traffic connections a re correctly terminated and crimped as per cable and connector

manufacturer instruc tions. All fiber optic patch leads should be routed carefully and efficiently, using conduits to prevent damage to the cables.

All other user termina tions are secure and correctly terminated.

All labeling is complete as per site requirements. Labeling is specific to each customer. At a site with

only one installation, labeling may be unnecessary. However, at sites with multiple insta llations, correct and adequate labeling is e ssential for future maintenance operations.

Typical labeling re quirements include: Antenna labels - for link identity and be aring

RFU labels - for link identity, frequency, and polarization Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint IDU labels - for link identity

Interoperability Verification

Connect the customer end equipme nt to the line interfaces and verify correct operation. Further interoperability tests should be performed in accordanc e with the specif ic requirements of the

connected end equipment.

Management Verificat ion

Install networ k management software on the PC and launch the program. Verify that you can manage the link and that you are able to perform changes to the link configuration

(frequency channel, TX power, system name, time & date, etc.) via the NMS.

Verify that the NMS reports the correc t parame ters when performing the above. Verify that there are no active alarms on the link. If the management station is loca te d a t a remote site (Network Operation Center), verify that the

management station can manage the link and receive traps.

2+0 XPIC Commissioning Procedure

Scope

This section describe s the recomme nded commissioning tests for a GE MDS Intrepid-HC HP radio link in a 2+0 XPIC Co-Channel-Dual-P o lariz ation configuration.

The purpose of the commissioning tests is to verif y correct and proper operation of the product. Important! Since operation of the XPIC system depends on correct installation, make sure the guideline s for

XPIC system installation provided be low are followed correctly.

XPIC Installa tion Gu idelines

Antenna and RFU Installation

1. Install the dual polar ization antenna and point it in the direction of the other site.

2. Install the two RFUs on a dual polarization a ntenna using the appropriate mounting kit, and mark the RFUs with V and H respectively.

IDU-RFU Cable Installation

1. Install two cables be tween the RFUs and the drawer s (IDMs). Note that cable length difference should not exceed 10 meters.

2. Mark the cables with V and H respectively, and make sure V is connected to the right drawer and H is connected to the left drawer.

3. Mark the drawers respectively.

Antenna Alignment

1. Power up drawer V on both ends of the link and configure it to the desired fre quency channel and maximum power.

2. Align the antennas, one at a time, until expe cted RSL is achieved. Make sure the achieved RSL is no more than +/-4 dB from the expected level.

Polarization Alignment

Polarization a lignment is required to verify that the antenna feeds are adjusted, to ensure that the antenna XPD (Cross Polari zation Discrimination) is achieved.

Polarization a djustment should be done on one antenna only.

3-12 MDS Intrepid-HC HP Installation and Operation

1. Power up drawer V on both ends of the link and record the RSL reading on one end.

2. Power off drawer V on that end and power on drawer H.

3. Check the RSL obtained on this RFU on H pol, and compare it to the RSL obtained by the RFU installed on the V pol.

4. Verify that XPI (Cross Polar ization Interference) is at least 25 dB where:



sites.both at usedon polarizati same with theRSLLink RSL

sites.both at used onspolarizati orthogonal with RSLLink RSL

5. If XPI is less than 25 dB, adjust the feed polarization by opening the polarization screw and gently r ota ting the feed to minimize the RSL

XPOL

Note that polariza tion alignment is not always possible since the RSL

may fall below the sensitivity

XPOL

threshold of the RFU. It is also recommended to try to maximize the XPI as much as possible, by aligning the polar ization.

XPIC Commi s si oning Tests

Individual Link Verification

Before operating in XPIC configur ation, each of the links (V and H) should be commissioned individually in order to verify its prope r operation.

1 Power up only drawer V at both ends and verify its frequency channel and TX power configuration. 2 Verify that the RSL is no more than +/-4 dB from the expected level. 3 Run BER stability test on the link for at least 15 minutes to ensure error-free operation. 4 Power up only drawer H at both ends and verify its frequency channel and TX power configuration. 5 Verify that the RSL is no more than +/-4 dB from the expected level. 6 Run BER stability test on the link for at least 15 minutes to ensure error-free operation.

XPIC Configuration Verification

1 Using the XPIC cable, connect the two RFUs at each end to the TNC connectors. Make sure the

cable is no longer than 3 meters.

2 Configure the drawers to work in XPIC mode. 3 Verify that the RSL at all four RFUs is no more than +/-4 dB from the expected level. 4 Verify that no alarms exist (if a 155 Mbps line is connected). 5 Run BER stability test on each of the 155 Mbps links for at least 1 hour to ensure error-free

operation.

Note: In a 2+2 configuration, repeat each step above for each of the four coupled RFU combinations.

XPIC Recovery Verification

In order to verify XPIC operation, simulate the faults described below.

1 Disconnect the IDU-RFU cable for each of the drawers (one at a time), and verify that the othe r

link is operating. 2 Disconnect the XPIC cable and check that the relevant alarms are generated. 3 Power down each of the drawers and verify that the other link is operating. 4 Swap the V and H cables and check that the relevant alarm is generated. 5 Mute and then un-mute one RFU at a time and verify that the other link is operating.

Note: In a 2+2 configuration, repeat each step above for each of the four coupled RFUs connected to the two standby IDUs.

2+2 Verification

Perform the tests spec ified in Switching Tests in the 1+1 Commissioning Proce dure section earlier in this guide.

In this case, the switch will be from a main IDU connected to the main V and main H RFUs, to the secondary IDU connected to the coupled V and coupled H RFUs.
