Glossary

V.25bis: An ITU-T standard for synchronous communications between a mainframe or host and a modem using HDLC or other character-

oriented protocol.

V.54: The ITU-T standard for local and remote loopback tests in modems, DCEs and DTEs. The four basic tests are:

• local digital loopback (tests DTE send and receive circuits),

• local analog loopback (tests local modem operation),

• remote analog loopback (tests comm link to the remote modem), and

• remote digital loopback (tests remote modem operation).

Virtual Circuit: A logical connection. Used in packet switching wherein a logical connection is established between two devices at the start

of transmission. All information packets follow the same route and arrive in sequence (but do not necessarily carry a complete address).
