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

When the system PQL transitions to a PQL that crosses the user-defined Output-
Squelching PQL threshold, the SSU generates the assigned alarm level. 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 Japanese Sine
Wave 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 8-10. Using the Hex Number to Identify Output Ports
Table 8-9 lists the failed output port number(s) for each possible hex digit. In the
above alarm message, the hex number is 00001. To determine the port in alarm,
locate the second row (corresponding to Hex Value 1) in
column has an X, which corresponds to Port 20 (read across from Digit 5).
As another example, if the hex number is A501F, then the following ports are
squelched: 1 and 3 (corresponding to the A in Digit 1), 6 and 8 (corresponding to the
5 in Digit 2), 16 (corresponding to the 1 in Digit 4), and 17 through 20
(corresponding to the F in Digit 5).
