Canopy T1/E1 Multiplexer
Action
Set E1 line code
NOTE: If the line code does not match the incoming E1 settings, then
Bipolar Violations (BPVs) will occur. The default code is HDB3.
Enter set line [1/2/3/4] code [HDB3/AMI]
where
[1/2/3/4] represents E1 ports 1 through 4.
[HDB3/AMI] represents the line coding scheme.
RESULT: The system responds
Line [1/2/3/4] code [HDB3/AMI]
Set timing mode
NOTE: Timing mode applies to all four E1 lines. Loopback mode loops the
T1/E1 Tx clock to the T1/E1 Rx. Recovered mode recovers the T1/E1 clock
from the incoming T1/E1 over Ethernet bit stream (recovers the clock from
the far end T1/E1). The default timing mode is Recovered.
For master clock timing mode, enter
set clock source loopback
RESULT: The system responds
Clock source is loopback
For slave clock timing mode, enter
set clock source recovered
RESULT: The system responds
Clock source is recovered
Set master clock
NOTE: This is the master clock reference for all four T1/E1 lines.
reference line
The default setting is T1/E1 Port 1.
Enter set master clock reference line [1/2/3/4]
where
[1/2/3/4] represents T1/E1 ports 1 through 4.
RESULT: The system responds
Clk ref line; [1,2,3,4]
