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.
