Isdn in a sentence

Another alternative ISDN configuration can be used in which the B channels of an ISDN BRI line are bonded to provide a total duplex bandwidth of 128 kbit/s.

Before B-ISDN, the original ISDN attempted to substitute the analog telephone system with a digital system which was appropriate for both voice and non-voice traffic.

Reference points A set of reference points are defined in the ISDN standard to refer to certain points between the telco and the end user ISDN equipment.

There are devices on the market that combine the functions of an ISDN TA with those of a classical modem (with an ISDN line interface).

This was intended to allow several terminals to share a single network connection, in the same way that two Integrated Services Digital Network (ISDN) phones can share a single basic rate ISDN connection.

After the middle of the 20th century, fax and data became important secondary users of the network created to carry voices, and late in the century, parts of the network were upgraded with ISDN and DSL to improve handling of such traffic.

All ISDN messages are tagged with an ID number relative to the switch that started the call (local/remote).

Almost all live sports broadcasts on radio are backhauled to their main studios via ISDN connections.

Annex B provides information on network identification, service parameters, calling/connected line identity, dialing procedures, and addressing for Geographic-based ISDN calls.

A T-interface or T reference point is used for basic rate access in an Integrated Services Digital Network (ISDN) environment.

Basic Rate Interface main The entry level interface to ISDN is the Basic Rate Interface (BRI), a 128 kbit/s service delivered over a pair of standard telephone copper wires.

BBC Radio 3 commonly makes use of three ISDN BRIs to carry 320 kbit/s audio stream for live outside broadcasts.

Because of different ISDN standards, a video bridge via Boston was used to achieve the link, which also featured interactive dancing.

BRI-ISDN is very popular in Europe but is much less common in North America.

Channel bonding can achieve a greater data rate; typically the ISDN B-channels of three or four BRIs (six to eight 64 kbit/s channels) are bonded.

Competing phone companies often offered ISDN only and no analog lines.

Due to the success of ISDN, the number of installed analog lines was decreasing.

Even though many network professionals use the term "ISDN" to refer to the lower-bandwidth BRI circuit, in North America BRI is relatively uncommon whilst PRI circuits serving PBXs are commonplace.

In common use, ISDN is often limited to usage to Q.931 and related protocols, which are a set of signaling protocols establishing and breaking circuit-switched connections, and for advanced calling features for the user.

In many countries, such as the UK and Australia, ISDN has displaced the older technology of equalised analogue landlines, with these circuits being phased out by telecommunications providers.
