2-2 Installation

1061 Multicast Card

T1 Multicast Port

The 50-pin female connector is used for the expanded out-

puts of either the A or B inputs per ANSI.T1 403-1988.

Alarm/Power

The Alarm/Power is a ten-pin connector used for supplying

power and providing alarm connections.

Alarm

The alarm connection operates in a normally closed mode

(NC - opens on alarm) on pins 6 and 9 or in a normally open

mode (NO - closes on alarm) on pins 6 and 10. The contacts

are rated at 1.0 amp AC or 1.0 amp DC over 18- to 20-

gauge wire (recommended).

External Alarm

These unpowered, isolated inputs indicate external alarms

on inputs A and B. External alarm A is connected on pin 1

(+) and pin 2 (-). External alarm B is connected on pin 3 (+)

and pin 4 (-). They are 10 mA current loops and must be

powered externally.

Power

The power connection requires a -48 VDC power source

capable of supplying 50 mA current. It supplies current to

the 1061 cards and generates a circuit alarm. The -48 VDC

lead is connected to pin 7 with the return lead connected to

pin 5. The chassis ground lead is connected to pin 8. When

connecting these pins, 18- to 20-gauge wire is recom-

mended.

Network Management

An NMS bus in the 1061 allows for network management

from an 8000 Element Manager or an 8100A Site Controller

as a remote or far end element via the SUPV port.
