• ISDN programming
Welcome to ISDN
Integrated Services Digital Network (ISDN) technology provides a fast, accurate
and reliable means of sending and receiving voice, data, images, text, and other
information through the telecom network.
ISDN uses existing analog telephone wires and divides it into separate digital
channels which increases bandwidth.
ISDN uses a single transport to carry multiple information types. What once
required separate networks for voice, data, images, or video conferencing is now
combined onto one common high-speed transport.
Nortel endeavours to test all variations of ISDN PRI on Enterprise Edge; however,
due to the number of variations, this is not always possible.
Analog versus ISDN
ISDN offers significantly higher bandwidth and speed than analog transmission
because of its end-to-end digital connectivity on all transmission circuits. Being
digital allows ISDN lines to provide better quality signaling than analog POTS
lines, and ISDN out-of band data channel signaling offers faster call set up and tear
down.
While an analog line carries only a single transmission at a time, an ISDN line can
carry one or more voice, data, fax, and video transmissions simultaneously.
An analog modem operating at 14.4 K takes about 4.5 minutes to transfer a 1MB
data file and a 28.8K modem takes about half that time. Using one channel of an
ISDN line, the transfer time is reduced to only 1 minute and if two ISDN channels
are used, transfer time is just 30 seconds.
When transmitting data, the connect time for an average ISDN call is about 3
seconds per call, compared to about 21 seconds for the average analog modem call.
