AMI
Digital information carried by two B-channels for better
performance and quality; the bit rate is twice that of one
B-channel used alone.
See ISDN 7500B Data Module
Code used to associate incoming and outgoing calls with
corresponding accounts, employees, projects, and clients.
AT&T's switched digital service for 56-kbps, 64-kbps
restricted, and 64-kbps clear circuit-switched data calls.
Coded representation of the destination of data or of the
data's originating terminal, such as the dialed extension
number assigned to the data terminal. Multiple terminals on
one communications line each must have a unique
address.
Automated Document Delivery System . Computer-based
application that stores documents in a database and
automatically faxes them on request.
Optional equipment used with the communications system,
such as an alerting device or modem that connects to a
multiline telephone or to an extension jack.
Automatic Line Selection . Programmed order in which the
system makes outside lines available to a user.
Numbering of extension ranges, remote access codes, or
other system components that causes conflicts in network
operations. These numbers can be unique and still be
ambiguous. For example, Extension 441 is different from
Extension 4410; for UDP routing purposes, however, the
two numbers are ambiguous and a call intended for
Extension 4410 would be misrouted, on the first three digits
sent, to Extension 441. See also
Alternate Mark Inversion . Line coding format in which a
binary one is represented by a positive or negative pulse, a
binary zero is represented by no line signal, and
subsequent binary ones must alternate in polarity;
otherwise, a bipolar violation occurs. AMI is used in the
DS1 interface.
