!CAUTION:
The p ower sup p ly c an be used  only with telec ommunic ations equip ment, 
indoors, and  in a c ontrolled  environment.
The power supply has a single output of -48 VDC, 0.4 Amps, and can operate 
from either a 120 VAC 60 Hz power source (105 to 129 VAC) or a 220/230/240 
VAC 50 Hz power source (198 to 264 VAC)....

BRI Terminating Resistor
The resistors balance the cable plant between the receiver and the transmitter on 
the interface. When using the TN2198 ISDN-BRI 2-Wire U Interface circuit pack, 
an NT1 is required. A terminating resistor is always required near the terminal 
when the BRI S-type interface circuit pack (TN556...

Closet Mounted (110RA1-12)
The 110RA1-12 terminating resistor block is designed to mount in the 
telecommunications wire closet. It consists of twelve 2-pair circuits and provides 
the 100 Ohm termination used for ISDN-BRI circuits.

For point-to-point wiring, the top row connects to the blue station field. The pair 
connects from the 110RA1-12 to the standard 4-pair circuit. Pair 1 from the 
110RA1-12 connects to Pair 1 of the station field, and Pair 2 connects to Pair 3...

Multi-point Adapters
Multi-point Adapters are used to provide signal fanout of the T-interface. Fanout 
can be performed at the work station by the BR851-B or the 367A. These 
adapters support more than one ISDN terminal per horizontal 4-pair D-inside wire 
(DIW). To support multiple horizontal runs, perform fanout in the...

367A Adapter
The 367A adapter provides fanout. See Figure 5-30. It can provide inputs to up to 
7 terminals. The 367A is an 8-conductor adapter and can be is used at the work 
location for bridging 3 to 7 terminals.

Add Circuit Packs
When installing additional features or equipment, it may be necessary to install 
additional port circuit packs. See Table 5-19
 for a list of circuit packs. This is a 
general procedure to use when adding features or equipment that require adding 
circuit packs.
