This chapter provides you with some background information about ISDN and also includes information about:. 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 them into separate digital channels, which dramatically increases the 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.
However, due to the number of variations, this is not always possible. Check with your service provider about compatibility. ISDN offers significantly higher bandwidth and speed than analog transmission because of its end-to-end digital connectivity on all transmission circuits. 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 Using one channel of an ISDN line, the transfer time is reduced to only one minute.
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 three seconds per call, compared to about 21 seconds for the average analog modem call.
B channels are the bearer channel and are used to carry voice or data information and have speeds of 64 kbps. The standard signaling protocol is transmitted over a dedicated data channel called the D-channel. The D-channel carries call setup and feature activation information to the destination and has speeds of 16 kbps. Data information consists of control and signal information and packet-switched data such as credit card verification. The layers include both physical connections, such as wiring and logical connections, which are programmed in computer software.
When equipment is designed to the ISDN standard for one of the layers, it works with equipment for the layers above and below it. To support ISDN service, all three layers must be working properly.
Norstar has two of these connections for each BRI line, one for each of the logical lines. Without Layer 2, call processing is not possible and there is no dial tone. This controls which central office services are available to the connection.
For example, a network connection can be programmed to carry data calls. The system of layers is important when you are installing, maintaining, and troubleshooting an ISDN system.
See Problems with BRI service on page for more information about working with the layers. Bearer capability describes the transmission standard used by the BRI line so that it can work within a larger ISDN hardware and software network. This allows you to add applications, such as point-of-sale terminals, without additional network connections. Any analog or digital network connections can be shared by all Norstar telephones, peripherals and applications, and ISDN terminal equipment TE.
However, terminal equipment which supports sub-addressing is not commonly available in North America. Contact your ISDN service provider for more information about these services and features. When your phone rings, this feature allows you to see the name of the person who is calling you. This call information is only available from the public network and must be activated on the public network side of the switch. For information about system programming of this feature, see. The user must invoke the feature code without hanging up, and within 30 seconds time varies on different networks after the caller hangs up.
NCD redirects calls using the same line on which they arrive. Call forward is efficient since there is no need for additional outside lines. This allows you to customize your arrangement of lines, voice terminals, data terminals and other ISDN equipment. This section describes some basic hardware configurations for network and terminal connections for each loop type. For detailed wiring information about BRI network and terminal connections see Installation on page Each loop can be individually programmed to provide one of the following:.
Each loop can be individually programmed as one of the following:. The loops must be on the same physical card. For example, if the network connection is a loop found on the BRI Card in Slot 1, the terminal connection must be a loop found on the same card.
To deliver D-packet service, a network connection T loop is programmed to work with a terminal connection S loop. Clocking synchronization is supported by a Services Cartridge. U-NT and T reference points loops. Systems synchronize clocking to the first available, functional, network connection.
If there are excessive errors on the reference network connection, or the loop fails, the next available, functional, network connection is used for clock synchronization. When you configure the network connections to the Compact ICS, you should take into account the system preferences for selecting loops for synchronization:.
Systems with only U-LT and S loops act as timing masters for the attached terminal equipment TE , and are not synchronized to the network. The NT1 network termination type 1 connects an S interface four-wire to a U interface two-wire. The NT1 converts and reformats data so it can be transmitted to and from the S or T connection.
In the U. Contact your service provider for more information about the capability packages it offers. If you want to transmit both voice and data, and support D-channel packet service, order package P.
However, Compact ICS does not support the flexible calling for voice and additional call offering features that are included in package P. Multi-Line Hunt may be ordered with your package.
When a telephone number the Network DN in the group of numbers assigned by your service providers is busy, the Multi-Line Hunt feature connects the call to another telephone number in the group. Norstar supports the feature only on point-to-point, network connections T loop or U-NT loop.
Check with your service provider for more information about Multi-Line Hunt. More detailed information is included under the individual headings and settings in the Programming and Maintenance sections. For complete card and cartridge installation instructions and safety precautions, see Installation on page Collect the information supplied by your service provider to support your ISDN package. If you are supporting a point-of-sale terminal adapter, you also need one or more terminal endpoint identifiers TEIs.
Disable each card under Maintenance. Select the type for each loop in Hardware :. Re-enable the card in Maintenance. If required, the card goes through a firmware download process, which takes five to six minutes.
Provision the loops and lines, as appropriate, in Maintenance programming. Replacement Notel desk phones at great prices.
