GM2s
Data Path
The data path (roundtrip) in an RLB test is shown schematically in
below.
This section describes the loopback tests for an LDx00 network using GM2s for connecting
access units.
RLB Test
Purpose
The RLB test is used to determine whether the local LDx00, WDM cabling connected to it, and
remote LDx00’s
WDM interface and GM2 access interface are OK.

Preparation
Local LDx00
1. Insert the GM2 in the
local
LDx00.
2. At the management station, invoke the CLI command:
set-transponder-lb [arg #0] [arg #1] opt.[arg #2] opt.[arg
#3]
where,
[arg #0] =
Slot number of the local GM2
[arg #1] =
1
(for GM2 access port 1) or
2
(for GM2 access port 2)
opt.[arg #2] = rlb
(RLB mode)
opt.[arg #3] = n
(enable normal mode)
Remote LDx00
1. Insert the GM2 in the
remote
LDx00
2. Ensure that the
remote
GM2 is connected to the
local
GM2 with intra- and inter-LDx00
cabling.

GM2 is model EM2009-GM2 or TM-GM2.
