A
Automatic Incoming Call Display
Displays information about an incoming call even if the telephone is already in
use.
Automatic Transmission Measurement System
Measures voice and data trunk facilities for satisfactory transmission
performance. The measurement report contains data on trunk signal loss, noise,
signaling return loss, and echo return loss. Acceptable performance, the
scheduling of tests, and report contents are administrable.
Barrier Codes
A security code used with Remote Access to prevent unauthorized access to your
system. To increase your system’s security, use a 7-digit barrier code with Remote
Access Barrier Code Aging. A barrier code automatically expires if an expiration
date or number of accesses has exceeded the limits you set. If both a time interval
and access limits are administered for a barrier code, the barrier code expires
when one of the conditions is satisfied.
NOTE:
Barrier codes are not tracked by Call Detail Recording (CDR). Barrier codes
are incoming access codes, whereas, authorization codes are primarily
outgoing access codes.
Bellcore Calling Name ID
Allows the system to accept calling name information from a local exchange
carrier (LEC) network that supports the Bellcore calling name specification. The
system can send calling name information in the format if Bellcore Calling Name
ID is administered. The following Caller ID protocols are supported.
■ Bellcore (default) - US protocol (Bellcore transmission protocol with 212
modem protocol)
■ V23-Bell - Bahrain protocol (Bellcore transmission protocol with V.23
modem protocol).
Block Collect Call
Blocks collect calls on class-of-restriction basis. This feature is available for any
switch that uses the Brazil country code. If enabled for a station, all trunk calls that
terminate to the station will send back a double answer to the CO. This double
answer tells the CO that this particular station cannot accept collect calls. The CO
then tears down the call if it is a collect call
.
