High Speed Data: Performance improvement (speed and accuracy) and connectivity is
becoming a major factor in ISDN data related applications. For example, computer database
interface works well on ISDN lines for large capacity file transfer, high resolution graphics
transfer, online transaction processing, and information retrieval applications. ISDN provides
better performance for these applications which require faster call setup and network response
times than older, more restrictive analog networks can provide. ISDN also provides higher
data accuracy than today's analog network.
Video Conferencing: Color video transmission requires greater bandwidth and flexibility for
video conferencing and related applications. Video conferencing systems integrate cameras,
displays, CODEC, and control unit. The CODEC can set up various transmission rates
between 64 kbps and 1.5 Mbps, as required.
High Speed Fax: G4 Facsimile via ISDN offers high speed and high image quality. G4 Fax
machines do not have to be isolated within a stand-alone system. Many G4 Fax machines can
also communicate with G3 Fax machines because the connection with existing networks is
handled by the ISDN side.
Telecommuting: The idea of employees working at home is a much more effective and
practical option with ISDN services. ISDN can provide employees working at home access to
office technology necessary to make them work almost as effectively at home as in the office.
PRI Static Integrated Network Access: Designed to eliminate the cost of maintaining separate
access lines for private-line services and switched services. The traffic over the two types of
access lines can be combined over the same access line.
Resource Sharing: ISDN lines can support local network functions such as printer sharing and
modem sharing by connecting these devices through terminal adapters. This enables users to
share equipment regardless of location. It also eliminates the need for dedicated connections,
since all network resources are available on a dial-up basis.
Carrier Gateway: This is the general "catch all" category that would be used to connect
anything to anything over the public network. Using ISDN for this purpose provides speed,
accuracy, and connectivity advantages for applications like Internet connection, e-mail, Telex,
Voice Mail, and Fax forwarding.
Benefits
Enables faster call setup times because a separate modem-type communication with the public
network is used. Calls using analog connections or T1 digital connections can take several seconds
longer before the connection is made because of DTMF tones.
Provides immediate Caller ID because it is transmitted with each call setup message. This makes
Caller ID information immediate rather than waiting for this information to be sent after starting
the ringing process as with analog lines.
Enables shared use of lines for voice, data, fax, and video on each channel for multiple purposes
based upon the setup request. Lines can be used for many services without the need for modems or
other devices, saving you money in monthly service charges.
Provides higher speed digital data connections for higher data accuracy. ISDN provides better
performance for applications that require faster call setup and network response times than older,
more restrictive analog networks can provide.
Enables DID-type functionality for direct incoming calls to route and ring at designated telephones
according to the number dialed. This provides DID functionality over ISDN lines without the
additional expense of purchasing a block of numbers from the telephone company and subscribing
to DID service.
