ECTION
For connections to other CPE-type equipment, such as an
ADTRAN TSU-100, a straight-through T1 cable is provided by
ADTRAN (part number 3127.004) and is included with the BBP.
VT-100 RS-232 I
A serial interface port using RS-232C signal levels is provided for
attaching a VT-100-compatible terminal. The connection is made
via a DB-25 connector on the rear panel. The data rate is configured
for 9600 bps, 8 data bits, no parity, and 1 stop bit.
A C
LARM ONTACTS
Two sets of alarm contacts are provided on the rear of the BBP:
major alarm and minor alarm. A major alarm indicates the radio
link is not operational. A minor alarm indicates that system
performance is degraded or that the T1 interfaces are experiencing
errors. Normally-open and Normally-closed contacts are provided
for both alarm types. Under normal operating conditions there is
no continuity between the Normally-open and Common contacts,
and, under an alarm condition, continuity between those contacts
exists. The Normally-closed and Common contacts normally have
continuity, while under alarm conditions, these contacts are open.
IF S
IGNAL
The N-type connector on the rear panel provides the interface
point between the BBP and the RFC. This connection provides
the data signal, power, and configuration information to the RFC.
A coaxial cable (ADTRAN part number 3125.001@A) is provided
for connecting the BBP to the RFC for the rack-mount model .
Cable for connecting the BBP to a mast-mount RFC must be
provided by the customer after the length of cable has been
determined.
