kbps (European data rates). It supports HDB3 line coding, which
meets the ones density without data corruption. This module
cannot be used for port connection to a channel bank.

Channel - An electronic communications path, usually of 4,000 Hz
(voice) bandwidth; physical or logical path allowing the
transmission of information. Generally, channel refers to an
individual DS0B Circuit with a DS0B bundle. Also see port.
Channel - Bank - Equipment used to connect to digital transmission
facilities. In the transmit direction, the channel bank performs
sampling, time-division multiplexing, compression, and encoding
in binary format. In the receive direction, the channel bank
performs decoding, expanding, and gating. The channel bank
must also detect and transmit signaling information for each
channel, transmit framing information to the receiving terminal so
that the time slots allocated to each channel can be identified, and
transmit alarm signals to the far terminal during a specified alarm
condition.
Channel - Capacity - The maximum information transmission rate
possible through a channel at a specified BER.
Channel - Time Slot - In time-division multiplexing, a time slot
starting at a particular phase in each primary frame and allocated
to a channel for transmitting pulse-coded voice or data signal. A
standard PCM system has 24 channel time slots.

Choke - Exchange - A telephone exchange which is assigned to
Radio and TV stations, Promoters, and other users which will be
receiving large numbers of simultaneous calls. The idea is to
group all of these users on a single exchange so when all routes
into that exchange are in use "normal" users (on other
exchanges) will not experience blocking of incoming or outgoing
calls. Trunks from other local exchanges into the choke exchange
are deliberately limited to just a few paths so callers will get an "all
trunks busy" instead of completely blocking their local exchange.
However, when one of the choke exchange users experiences a
large number of calls (as when your station runs a contest) the
other choke exchange users will be blocked because all trunks
into the choke exchange will be busy. See Blocking and
