Output Module Reference Data
E1/2048 kHz Output Module
186 SSU-2000 User’s Guide 12713020-002-2 Revision D – April 2004
For example, you can provision output ports 1 through 5 for a threshold PQL of 3
and you can disable squelching for ports 6 through 20 (PQL is set to 0). In this
example, if the system PQL is 1, 2, or 3, ports 1 through 20 generate outputs. If the
system PQL changes to 4 or higher, outputs on ports 1 through 5 are squelched
(turned off) and ports 6 through 20 continue to generate outputs. The response from
the Output Status command appears as shown below:
SSU+>out 2a10

CRC, CAS, and SSM are enabled.
SSM are available in all 5-bit (4-8) positions.

Squelch:
P[ 1]= 3, P[ 2]= 3, P[ 3]= 3, P[ 4]= 3, P[ 5]= 3,
P[ 6]= 0, P[ 7]= 0, P[ 8]= 0, P[ 9]= 0, P[10]= 0,
P[11]= 0, P[12]= 0, P[13]= 0, P[14]= 0, P[15]= 0,
P[16]= 0, P[17]= 0, P[18]= 0, P[19]= 0, P[20]= 0,
When the System PQL transitions to a PQL that crosses the user-defined Output-
Squelching PQL threshold, the SSU generates a major alarm. The alarm message
for Squelch indicates which port(s) are in alarm due to the PQL threshold being
crossed. In the example Alarm message below, Port 20 of the E1/2048 kHz Output
module is in alarm.

A five-digit hexadecimal number (consisting of 20 bits) at the end of the alarm
message identifies the affected port(s). Each digit represents four of the 20 ports on
the module; the first digit represents ports 1 through 4, the second digit represents
ports 5 through 8, and so on, as shown in Figure 8-7.
