WAN Card User Screens and Settings WAN Card
LB ADDR
The Loopback Address setting, in conjunction with the Channel Loopback setting, specifies
which channel is to be looped back. Only one channel may be looped back at any one time for
each E1 link. The valid selections for E1 lines are 1-31. Do not loop time slot 16 unless the E1
interface is in no signaling (nos) mode.
LB GEN
The Loopback Generate setting generates out-band diagnostic codes that are sent to the remote
equipment. These codes are compatible with DDS networks and allow you to command a
latching loopback at remote DDS equipment. The options are off, llb (Line Loopback), plb
(Payload Loopback) and nlb (Network Loopback).
Selecting off generates a loopback deactivate command corresponding to the last activation
command generated. e.g. if you send a plb command and then send an off command, the off
command would be payload deactivate. Note that the actual transmission of the command
happens after you press ‘s’ for Save. If you have already sent one of the loopback activation
commands, it is recommended that you send an off command before sending another loopback
activation command. e.g. this set of selections plb, off, llb, off transmits the following
commands: payload activate, payload deactivate, line activate, and line deactivate.
COM/NMS RP
The Communications/Network Management System Report setting tells the system where to
send TCP/IP packets from the NMS configuration selected on the Interface card. The options
are none (no NMS), c-sa4 (use SA4 channel for NMS information), c-b7r (send NMS
information to a B7R card on time slot 31), and e-sa4 (send NMS information in a proprietary
ESF format via the SA4 channel to a NTU).
EER THRHD
The Excessive Error Rate Threshold selects the error rate, which an alarm is declared. This
setting interacts with the EER setting in the Alarm Filters of your system. The options are
10e-4 through 10e-9, or none.
RDNT RULES
The selection of Redundancy Rules will define the method of determining what event will
trigger a WAN port to switch to its redundant mate. The options are none, OOS, or CGA. See
Chapter 3-C for more information on redundant WAN card operations. If there is no redundant
WAN card in the appropriate slot, the only option that will appear is n/a.
