LB - Loopback Test on Port
Format: LB,mm,pp,[options]
This command runs a loopback test on the port specified by card mm port
pp.
Options:
i Do internal loopback tests within the ACC interface
card on this port.
e Do e xternal loopback tests. These tests require a
loopback connector to be connected to the breakout
panel on the specified port.
For serial cards the external loopback is performed using RS-232 or V.35
signaling depending on the type of panel attached. For T1/E1 cards E1
mode is set and all 31 available timeslots are used. If no options are
specified, the assumed default is “i”.
For any type of ACC card, all terminals on the port must be disabled
before the test is run.
NOTE For the Z7200A, Z7350A, and Z7400A ACC cards, the test can only be
run if the following two conditions are met:
1. The PORTTEST protocol has been included in the download file.
2. A PORTTEST terminal has been defined for this port
The following is an example of a non-E1/T1 P ORTTEST Term entry for
port 3 of ACC card 1:
TERM 500 1:3 PORTTEST 0000h 0000h 99,0,0,0,0 ”For Loopback Testing”
For E1/T 1 ACC cards there is no special configuration required t o run
the port test. Also there is no need to select a signalling type
(ie. option “2”). The loopback t est is performed using all available
timeslots that use the E1 standard.
