AUXILIARY CIRCUIT AND CONTROL CARRIER OUTPUTS (AUXILIARY) LABELS
The labels shown in Figures 3-37 and 3-38 are used to identify auxiliary circuit appearances
and control carrier AUXILIARY connector outputs. The top half of the labels are used for
custom identification of auxiliary circuit appearances and must be filled in manually. The
bottom half of the labels are used for the control carrier AUXILIARY connector outputs.
The control carrier AUXILIARY connector outputs include the following:

The Initialization and Administration System (INADS) trunk connection location.
For the System 75 XE, access to a relay contact is available for a customer-provided
alarm that can be used to connect a light, bell, or similar type device. The relay can
be administered so that it will make contact when a major, minor or warning alarm
condition exists on the system. The circuitry required for this feature must be
provided by the customer. The device connected to the alarm leads must not exceed a
rating of more than 100 volts at 3/4 amps.
