DTIC Not Up
The supervisor terminal is presented when you use the CONNECT command to connect to the DTIC. The
supervisor terminal may indicate that the DTIC is up or has not stayed up. This problem is likely caused
by the E1 trunk being down.
Once logged onto the DTIC, you can request the status of the trunk, the card in general, and any of the 30
ports (channels). An example of the status for a bad trunk follows. The trunk, card, and port 1 (channel 1)
status are shown in order.
To request the statusof the trunk, at the dtic> prompt, enter

-The TRANSMIT Traffic field showsDisabled, which indicates that the card will not transmit.
-The RECEIVE State field shows Loss of Signal (LOS), which indicates that the E1 trunk is not being
detected.
Because the main trunk is LOS, timeslot 16 will also have problems −its state is Out of Frame. The card
state or CM state is still on-line because itis operational but cannot complete calls because of trunk
problems. If the state is not On-line, the card also will not correctly complete calls. The following gives
basic information about the fields for the status of the trunk.
