13.3.1.1 XTC Front Panel

The XTC cards have an alarm cutoff (ACO) button, an RJ-45 LAN port, an EIA/TIA-232 TL1 (CRAFT)
interface port, and a LAMP TEST button. The XTC-28-3 front panel has 12 LEDs, and the XTC-14 front
panel has 11. The following list describes each LED:

13.3.1.2 Support for DS-1 and DS-3
The XTC cards contain the circuitry for connecting DS-1s. The XTC-28-3 also contains the circuitry for
connecting DS-3s. The XTC-28-3 supports 28 DS-1s and 3 DS-3s. The XTC-14 supports 14 DS-1s. The
DS-1 circuitry on the XTC cards maps each of the received DS-1 signals into VT1.5s and concatenates
these virtual tributaries (VTs) into one STS-1. Full VT1.5 grooming is supported.

The red FAIL LED indicates an XTC hardware problem. Replace the unit if the FAIL LED persists.
The ACT/STBY (Active/Standby) LED indicates whether the XTC is active and providing timing
reference and shelf control (green), or is in standby to the active XTC (yellow).
The green SYNC LED illuminates when the active XTC qualifies a timing reference from the optical
facility or an external BITS input.
The ACO LED indicates that the ACO function has been activated. To activate the ACO, press the
ACO button on the front panel.
The DS3 SF LED (XTC-28-3 only) indicates a signal fail/problem with one or more of the DS-3
interfaces.
The DS1 SF LED indicates a signal fail/problem with one or more of the DS-1 interfaces.
The green PWR A and PWR B LEDs illuminate when adequate power voltage is being received by
the PWR A and PWR B connections on the MIC cards.
The CRIT LED illuminates when a critical alarm is present.
The MAJ LED illuminates when a major alarm is present.
The MIN LED illuminates when a minor alarm is present.
The red REM LED illuminates when a remote alarm is present in one or several of the remote
terminals.
