1.3.120 TRMT
• Major, Service affecting
A TRANSMIT alarm occurs when there is a transmit failure on the DS-1 card because of an internal
hardware failure. The card must be replaced.
Procedure: Clear the TRMT Alarm on the DS-1 Card
Step 1 Replace the DS-1 card reporting the failure.
Note When you replace a card with an identical type of card, you do not need to make any changes
to the database.
Step 2 Call the Technical Assistance Center (TAC) at 1-877-323-7368 to discuss the failed card and possibly
open a returned materials authorization (RMA).
1.3.121 TRMT-MISS
• Major, Service affecting
A Transmit Missing 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 DS-1 port or the
backplane does not match the inserted card; for example, an SMB connector or a BNC connector
connects to a DS-1 card instead of a DS-3 card.
Note DS-1s are four-wire circuits and need a positive and negative connection for both transmit and
receive.
Procedure: Clear the TRMT-MISS Alarm
Step 1 Check that the device attached to the DS-1 port is operational.
Step 2 Verify that the cabling is securely connected.
Step 3 Verify that the pinouts are correct.
