Table 5-11. Diagnostics Parameters
Parameter Possible Value Description
Device Number Local
Remote
Identifies whether
parameters shown are for
the local or remote device.
Link Loop type No Loop
LLB
RLB
Identifies the type of loop
set on the uplink port:
• LLB – Loopback set on
local device
• RLB – Loopback set on
remote device.
Link LLB loop timeout 1 to 255 (test runs for the
specified number of
minutes)
Default: 5
The duration of the
loopback test, in minutes.
This value applies to both
uplinks and T1 loopback
tests.
A value of 0 can only be
set on the local device.
Channel's Loops Displays the T1 Loop
menu (see
Figure 5-11 ).
Clear all Channel's loops Clears all T1 loops
³ To run a loopback on an uplink:
1. Set Device Number to the device being configured (Local or Remote).
2. Set the uplink LLB loop timeout to the number of minutes the loopback must
run.
3. Set uplink Loop type to the type of loop to run on this device (LLB or RLB).
The loopback test begins running immediately after the loopback is set.
Setting the Uplink Local Loopback (LLB) in the remote Optimux-106 disconnects
the link, and as such, is irreversible. To remove this loopback, connect a terminal
to the remote unit or shut down the power to the remote unit. If you set the
Uplink LLB timeout on the remote Optimux-106, the loopback test will stop after
the specified timeout period.
Setting T1 Channel Loopbacks
The device being configured is set in the Diagnostics Menu ( Figure 5-10 ). The
loopback on each port is set via the following screen.
