Wiring to the Channels
LED Error Display
If a critical error occurs during reset or power-up of a Universal or Tone/Local DCC, its
front panel ERROR LED illuminates. Certain other LEDs flash to indicate which error
. The channel card is disabled as long as the error is active.
Try resetting the channel card to clear the error. If the error persists, it indicates a hardware
failure, which requires factory service.

Wiring to the Channels
The radio channel interface is performed by the DCC. Each DCC has terminations for two
transmit/receive channels known as “Channel A” and “Channel B”. A number refers to all
48 channels in the system, channels 1-48. The channel numbers that a DCC controls are
determined by the card slot into which the channel card is plugged. The connections
between the DCC and the radio base stations are made through the 50-conductor male
plugs on the back of the channel cardcage. The connections for a pair of DCCs (four
channels) are carried by one of these 50-conductor plugs. An AUX I/O in a slot will output
its 12 relays to the 50-conductor plug.
