Explanation
Standby Maintenance software is testing the
standby circuit pack (the standby
Tone-Clock is providing tones).
Active TN2182 has lost all external references
and is in holdover mode.
Other green and yellow patterns Active Maintenance software is testing the active
circuit pack.
Random yellow Standby If the circuit pack is a TN2182, the yellow
LED may come on and off intermittently as
ETR-PTs on the board are used for tone
detection services.
1. For a Tone-Clock in the master port network, the external source is the primary or secondary DS1 source,
or a Stratum 3 clock. For a Tone-Clock in a slave port network, the external source is the Expansion
Interface circuit pack.
1. If the Tone-Clock circuit pack to be replaced is active, then switch to the other Tone-Clock
circuit pack by the following procedure:
a. set tone-clock location, where location is the physical address of the
standby Tone-Clock circuit pack.
Note:
a critical-reliability system (duplicated PNC), the system generally expects a
PN to have its “preferred” Tone-Clock circuit pack active. For the first PN in a
given cabinet, this is carrier A. For a second PN in the cabinet, this is carrier E.
b. If the interchange was not successful, the standby Tone-Clock circuit pack may be
defective. In particular, if the error message must use override is displayed, fix the
standby Tone-Clock circuit pack before attempting to replace the active one.
2. Pull out the defective Tone-Clock circuit pack. No calls should be affected. If this is a
TN2182 circuit pack, some ETR-PTs may be in use and removal of the pack will affect
some individual users. It may be less disruptive to busyout the standby TN2182 before
removing it.
3. Insert a new Tone-Clock circuit pack of the appropriate code in the same slot where the
defective Tone-Clock circuit pack was removed.
4. Test the new Tone-Clock circuit pack using test tone-clock location long to
make sure it is functioning properly. If the Tone-Clock circuit pack is being replaced due to
loss of clocks, the Clock Health Inquiry (#46) will still report a failure, proceed with the next
step.
