Using The Hex Number To Identify Output Ports - Symmetricom SSU-2000 User Manual

To enable the squelching feature, you must provision a "threshold" PQL value using
the OUTPUT command (for ICS mode) or the SET-PRMTR-CLKOUT command (for
TL1 mode). A threshold PQL value of zero disables the squelch function. Threshold
PQL values above zero enable the squelch function; when the system PQL is
greater than the threshold PQL, the output is squelched.
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
(disabled) and ports 6 through 20 continue to generate outputs. The response from
the Output Status command appears as shown below:

When the System PQL transitions to a PQL that crosses the user-defined Output-
Squelching PQL threshold, the SSU generates an alarm. The alarm message for
Alarm #14, 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 RS-422 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
