10BaseT Ethernet connection
The ATLAS 800 RJ-48C port that provides Ethernet LAN connection for TFTP, SNMP, and Telnet.
AMI
alternate mark inversion. A Layer 1 line code used in a T1 carrier. Zeros are transmitted as zero volts,
and ones are transmitted as pulses that alternate polarity. Although B8ZS is an enhancement to AMI,
B8ZS and AMI are normally referred to as mutually-exclusive options for a T1. (See also B8ZS.)
ANI
Automatic Number Identification. Service provided by a local phone company that provides incoming
Caller ID information.
Async-232 Module
One of the ATLAS 800 option modules. The Aysnc-232 provides sixteen asynchronous EIA-232 DTE
ports and serves as an interface between terminal servers and other DTE equipment.
ATLAS 810
PLUS
A bandwidth management system which functions as a central site multiplexer. (See also Integrated
Access System.)
B8ZS
bipolar eight zero substitution. In a T1 carrier system, a specific eight bit pattern containing two delib-
erate bipolar violations which replaces eight consecutive customer zero bits. (See also 10BaseT Ethernet
connection.)
B channel
bearer channel. Bearer channels of an ISDN service carry provide data transmission. Compare with
D channel.
bandwidth
The transmission capacity of a communications channel, stated in megabits per second (Mbps).
Basic Rate ISDN
See BRI.
bit
Bit is a contraction of the term binary digit. It is the smallest unit of information a computer can pro-
cess representing either high or low, yes or no, or 1 or 0. It is the basic unit in data communications. A
bit can have a value of zero (a mark) or one (a space).
