Telnet

A terminal access protocol for accessing remote devices over an IP-based
network. The protocol provides support for various types of terminals and is
typically found in IP- or UNIX-based environments.

To establish a Telnet connection, you need both a Telnet client and a Telnet
server. The Telnet client resides on the local device and connects to the Telnet
server on the remote device. Nortel Multiservice Switch nodes act as both a
Telnet server (for incoming Telnet connections) and a Telnet client (for
outgoing Telnet connections).

time-division multiple access

interpolation). TDMA is now used in cellular and other wireless
communications.

time-of-day accounting (TODA)

Time-of-day accounting allows for accounting records to be generated up to
24 times for each day. TODA entries must be a minimum of one hour apart and
a maximum of 12 hours apart. The DCS-managed table holding 24 entries
manages this accounting feature. When TODA is enabled the system is in
TODA mode. A TODA changeover occurs whenever the actual time of day
changes from one interval to another. See

timer-mode accounting (page 134)
