FlexWave EMS Overview

As shown in Figure 5-2, you access the embedded EMS through the Host, where RF signals are converted to optical signals for distribution to the local coverage area. The EMS is thus in a position to monitor both types of signals, and to report status, alarms, and RF signal levels through automatic, periodic updates and in response to user requests. User requests can include commands to set RF gain and propagation delay.

5.5 EMS ALARM INDICATIONS

Some EMS parameter values are associated with alarms. When a parameter enters an alarm state, an alarm status indicator is activated where the color of the indicates the alarm severity (Figure 5-5):

•• Red status indicator—major alarm

•• Yellow status indicator—minor alarm

•• Green status indicator—normal (okay) state

•• White status indicator—a device or component is not communicating, but is in the

EMS database

•• Grey status indicator—alarm is masked.

5.6 EMS SYSTEM REQUIREMENTS

The computer that you use to remotely access the EMS must meet the following minimum requirements:

•• Windows 2000 or Windows XP operating system

•• Internet Explorer version 6.0. When a direct connection is made, an internet

connection is not needed, but the user interface still displays in a Web browser.

•• Network Interface Card (NIC)

•• Ethernet cable with RJ-45 connectors.

The EMS database can also be accessed remotely using an SNMP manager. In this case, the user interface varies depending on the SNMP manager, but the underlying parameters, parameter values, and alarms are the same as in the standard EMS interface.

Configuring a Host DART provides information required for the DART to operate in RF transmission. Each DART is configured in hardware to operate within a specific RF band such as PCS or Cellular; the passband is a software-defined sub-band of the hardware-defined band. Forward and reverse path gain, diversity status, and operating mode may also be set when a Host DART is configured. The same settings are applied to the Remote DART when linked to the Host DART. The Host has eight slots for DART cards.

6.9 LINK THE HOST AND REMOTE DARTS.

If you are setting up a multi- host sys tem, go to “(Optional) Configuring Multi-Host

Systems for Manual Mode” on page 168.

“Linking” establishes an association in software between a particular Host DART and a particular Remote DART, enabling the two DARTs to act as an operational unit in providing one RF band. There are four pre-requisites to this procedure:

•• The Host DART and Remote DART must be connected through the optical fiber

and be communicating with each other.

•• The Host DART card must be configured as described in “Configure the Host

DARTs” on page 152.

•• The Host and Remote DARTs must be of the same type (such as, Cellular or PCS).

•• There must be a sufficient number of fiber timeslots available in order to

accommodate the requested passband (for example, PCS A band requires 3 timeslots).

In the Remote DART configuration page, all Host DARTs are listed that have the same band as the Remote DART. A link is established by selecting a Host DART to be paired with the Remote DART.

6.9.1 Use of Multi Fibers

The EMS provides the ability to install “multi fibers” between a Host and Remote. This means that, in addition to the minimum two fibers (RX and TX) in the Host to Remote connection, one or more additional fiber pairs are installed. This is done to increase the bandwidth between the Host and Remote. Each fiber pair can handle approximately 75 Mbps of RF bandwidth.

Each fiber is capable of supporting 12 TDM timeslots:

•• Classic DARTs or Single SuperDARTs support up to 35 MHz of RF

– Cellular

–SMR800

–SMR900

– PCS Narrowband

–AWS Narrowband

–EGSM900

•• Dual SuperDARTs support up to 75 MHz of RF

– GSM1800

–UMTS

–AWS Fullband

Alarm Summary of RF Groups

Module / Band N

Alarm Summary of RF Groups

When a Host DART is linked to a Remote DART in a multi-fibers configuration, the EMS uses the first fiber (in numerical order) on which the required number of timeslots is available for the passband being linked. The EMS will not divide up the timeslots between two fibers. So, for example, if the passband requires eight timeslots, and only six timeslots are available on the first fiber, the EMS will bypass the first fiber and assign all eight timeslots to the second fiber, leaving four timeslots unused on the second fiber.

DART Forward Delay

DART Reverse Delay

Apply

400 In the

box, set in microseconds the actual delay that will be applied to the RF forward path signal. The minimum delay required is calculated. The acceptable range of delays is 88us. If you attempt to set the delay to a value outside the allowed range, the DART uses either the minimum or maximum, dependant on whether the DART is exceeding the set delay (too high or low).

Be aware of simulcast links. Observe the minimum delay required for the longest link, and set the delay to the same value for all simulcast nodes in the same connection based on this value.

Here is an example:

•• Fiber has 8 usec per mile of fiber.

•• Remote 1 has 5 miles of fiber (40 usec of fiber delay).

•• Remote 2 has 10 miles of fiber (80 usec of fiber delay).

•• Remotes are set to Cellular A"/A Band which has 8 usec of system delay. The

delay ranges will therefore be:

– Remote 1 delay (48-136)

– Remote 2 delay (88-176)

The system calculates these delay values—this is a typical example based on the fiber lengths provided. You select a delay value that’s within the range calculated by the system.

Set the delays to the same values for all nodes in the network in order to:

•• Optimize simulcast

•• Make BTS datafill changes simple (same delay offsets for all nodes)

•• Simplify E-911 integration (same delay offsets for all nodes)

Delays cannot be shortened; they can only be lengthened. The recommended approach is to normalize all Remotes to the longer minimum delay. In this example the delay would therefore have to be 88 usec.

411 In the

box, set in microseconds the actual delay that will be applied to the RF reverse path signal. The actual delay of the RF path will be within 1 usec. For E-911 TDOA applications, the reverse path delay must be measured to achieve the +/- 50 nsec delay accuracy specified for DAS networks. The FWD and REV delay values are usually the same because the fiber path between the two is typically the same.

Multi-Host systems must be set to Manual linking mode so each side of the link (Host and Remote) can be established independently. The Network Administrator must also manually specify the fiber, timeslots, pass band, and diversity status for each end.

7.4 WORKING WITH PRISM SYSTEM NETWORK INTERFACES

You use the EMS to configure the Prism system for one of the two different modes listed below, which affects how you configure the network interface of the Network and Craft ports and how you access the system through the EMS. In each mode, the Host and its subtended Remotes require the same configuration. Both modes require a DHCP server, which assigns an IP address to the Host and its subtended Remotes.

•

mode—is the default mode. The Host and subtended Remotes are DHCP clients and expect IP addresses to be assigned by an external DHCP server through a network Ethernet connector. If there is no external DHCP server, the Host will not be able to communicate with any connected Remotes.

The Host Craft port has a DHCP server that you can use to communicate with the Host directly. The IP address for the Host Craft port is 192.168.0.1. You can access the EMS via the Craft port, but if the Network port is not connected to an external DHCP server, the Remotes will not be visible to you.

•

mode—

mode is best suited for when there is no network to connect to or if the Prism network does not have a DHCP server. In Built-In Network mode, the functionality of the Network port and the Craft port are swapped. You connect a laptop to the Host Network port, which is assigned a default fixed IP address of 10.0.0.1 and all subtended network interfaces obtain a DHCP address in this same subnet. Alternatively, in Built-In Network mode you can connect the Craft port to an external DHCP server from which the Craft port obtains its IP address.

Static Mode—You also hav e the option of giving the devices on your Prism system static IP addresses.

There are potential problems in switching between the External Network and Built- In Network modes. If addresses on a public network. Set the it.

The Remote network port obtains its IP address from the external DHCP server.

You can reach the Remote via telnet or ssh from the Host.

The Remote Network port is a LAN/WAN connection to the network to which the Host Network port is connected. The Remote Network port therefore obtains an IP address in the 10.0.0.x range from the DHCP server in the Host.

You can reach the Remote via telnet or ssh from the Host.

7.4.2 EMS Access Methods

The FlexWave EMS has four access methods that are listed below and as shown and numbered in Figure 7-3.

11 A laptop subtended to the Craft port on the Host provides direct access to the

EMS. In this scenario the Host and the Remote can be configured and monitored through the EMS. This is the default access scenario during initial configuration and commissioning as described in “Access the EMS” on page 144.

22 A personal computer with a Web browser connected through the internet or

intranet to the Network port on the Host. This method provides a remote user access to the EMS through a Local Area Network (LAN) or Wide Area Network (WAN). In this scenario the Host and subtended Remotes can be configured and monitored through the EMS. After initial system setup, this is the default access method.

7.4.2.1 Accessing the EMS Through the Remote Network Port

The Remote provides a Network port allowing communications with the internal processor and transfer of service data to the optical protocol allowing IP servicing between the Host and Remote(s). This port is customer accessible for monitoring the interface with the subtended Host and ENET subtended devices at the Remote. The Network port is 10/100/1000 BASE-T MDI and requires a minimum of CAT 5 cable.

Although the Netw ork port on the Remote is a GigE port, the available bandw idth is only 100Mbps (part

7.4.2.2 Accessing the EMS Through the Remote Craft Port

You can use the Craft port on the SeRF Module to access the FlexWave EMS to view system configuration and alarms. For example, if there is a problem communicating with the Remote and you have determined that fiber is not the issue, connecting to the Craft port helps you obtain beneficial troubleshooting information.

When you access the E MS through the Remote Craft port, the EMS GUI shows only the Remote in its Funct clear alarms.
