NMS Connections

The NMS ports are used to connect the chas-

sis into the 8100A Site Controller. Within the

chassis, each unit is physically connected to

the next unit in a daisy chain. Two 6-pin

modular connectors are provided for both the

A and B sides.

All units in the

chain must use

the same NMS

bit rate, how-

ever, each unit

in the NMS

chain must

have a unique

address.

Network and DTE

Connections

The T1 DTE

and T1 NET

ports are 8-

pin modular

jacks. The

maximum

suggested

cable lengths

for chassis

connection

to the net-

work are listed in the following table. These

distances are based on a temperature of 70°F,

0.083 µF/mile capacitance, a 27 dB loss, and

a 100 Ω, non-loaded, twisted pair cable.

Alarm Connections

Alarm conditions from all modules in the

chassis are bused together in parallel and are

presented on a single set of alarm relay con-

tacts (TB1, pins 3 and 4) allowing connection

to a remote indicating device. All modules in

a common chassis must operate in the nor-

mally open (NO) mode.

Connections to the contacts should use 20-

gauge stranded wire (or similar). The contacts

are rated at 120 mA (AC or DC).

External Clock

Connections

TB1 provides the contacts allowing connec-

tion to an external timing source (pins 1

and 2).

High-Speed DTE

Connections

The high-speed port connections use a

female 25-pin subminiature DB-25 connec-

tor. The pin interface comparisons are de-

tailed in the table on the right.

If the unit is connected to an EIA-530 DTE

type device, only a one-to-one DB-25 cable

is required.

If the unit is connected to an RS-449 com-

patible interface, an adapter cable must be

used to match the 37-pin RS-449 standard.

The V.35 option also requires an appropriate

adapter cable to connect to devices that use

the standard 34-pin V.35 interface.
