Uneq-P - Cisco ONS 15327 User Documentation

Alarm Procedures
A facility-termination equipment transmitter missing (TRMT-MISS) alarm occurs when the
facility-termination equipment detects an incorrect amount of impedance on its backplane connector.
This means transmit cable is missing on the XTC-14 port or the backplane does not match the inserted
card; for example, an SMB connector or a BNC connector connects to an XTC-14 card instead of an
XTC-28-3 card.
DS-1s are four-wire circuits and need a positive and negative connection for both transmit and receive.
Note
Procedure: Clear the TRMT-MISS Alarm
Check that the device attached to the XTC-14 port is operational.
Step 1
Verify that the cabling is securely connected.
Step 2
Verify that the pinouts are correct.
Step 3
If Steps 1 to 3 do not clear the alarm, replace the transmit cable.
Step 4

14.4.124 UNEQ-P

•
A signal label mismatch failure unequipped path ((UNEQ-P) alarm occurs when the path does not have
a valid sender. The UNEQ-P indicator is carried in the C2 signal path byte in the SONET overhead. The
source of the problem is the node that is transmitting the signal into the node reporting the UNEQ-P.
UNEQ-P occurs in the node that terminates a path. The path layer is the segment between the originating
equipment and the terminating equipment. This segment can encompass several consecutive line
segments. The originating equipment puts bits together into a SONET payload and the terminating
equipment breaks the bits apart again. SONET multiplexers, such as the ONS 15327, often perform the
origination and termination tasks of the SONET payload. A UNEQ-P error message on the ONS 15327
indicates that the node reporting the RFI-P is the terminating node on that path segment.
Deleting a circuit affects traffic.
Caution
Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband

cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Note If you have created a new circuit but it has no signal, an UNEQ-P alarm is reported on the OC-N cards
and an AIS-P alarm is reported on the terminating cards. These alarms clear when the circuit carries a
signal.
Procedure: Clear the UNEQ-P Alarm on the Line Card
