The control carrier AUX connector outputs include the following:
■ Alarm monitoring for the auxiliary cabinet
■ Seven -48VDC power sources for emergency transfer units
■ Three -48VDC power sources for remotely powering three attendant
consoles or telephone adjuncts.
■ The INADS (remote system management terminal interface) trunk

■ Access to a relay contact is available to actuate a light, bell, or similar
type customer-provided alarm device. The relay can be administered to
make contact when a major, minor or warning alarm condition occurs in
the switch. 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 100 volts at 3/4 amps. The pinouts for an external alarm are
shown in Table 9-6 on page 9-11.
A connector labeled

is provided on the back of the control carrier. Connect
a 25-pair cable from this connector to a connecting block of the trunk/auxiliary
