Provisioning the ISDN BRI Line for Cisco 700 Series Routers

This appendix describes how to order and configure the Integrated Service Digital Network (ISDN) Basic Rate Interface (BRI) line to operate with the Cisco 700 series routers.

Both the BRI line configuration and the router configuration are dependent on the BRI switch type being used for the BRI line. BRI switches that comply with the NI-1 standard provide the best performance with the Cisco 700 series routers voice priority feature. If possible, order this type of switch from your ISDN BRI service provider.

This chapter contains the following sections:

Data and Voice Application over ISDN BRI

The Cisco 753, Cisco 765, and Cisco 766 support data and voice applications. The voice applications on these three router models are implemented with ISDN BRI and through the analog telephone port on the router.

Note This appendix describes how to provision the ISDN line for both data and voice applications. Some ISDN service providers might charge a lower rate for an ISDN line that supports only data applications. If you do not require voice capability on your ISDN line, provision the line for data application support only.

The BRI line supports the following data and voice applications on the Cisco 753, Cisco 765, and Cisco 766:

The BRI line supports the following voice-only applications for these models:

Note There might be an additional charge for configuring the BRI line to support some of these features. Check with your service provider.

Table B-1 describes the data and voice application features supported by the ISDN BRI line.

Table B-1 : ISDN BRI Data and Voice Applications---Description

Feature Description

Caller ID, calling party identification Identifies the remote system that originated the call.

Subaddressing Provides locally address terminals within a specific ISDN access area.

Speech/3.1 kHz audio bearer capability Enables use of terminal equipment that supports voice applications. Examples of this type of equipment are ISDN telephones and terminal adapters, and the Cisco 753, Cisco 765, and Cisco 766.

Multiple subscriber numbers Enables the use of multiple directory numbers on the same ISDN BRI line. Each piece of terminal equipment on the same BRI line can then be assigned its own directory number.

Call hold and retrieve Enables a call in progress to be put on hold and then retrieved.

Call waiting, also known as additional call offering (ACO) Enables the presentation of more calls than the number of ISDN BRI channels supported by the terminal equipment. The router can be configured to either ignore the additional calls or to disconnect a call in progress to accept the additional call.

U.S. ISDN BRI Switch Types

The following section describes the BRI switch types that are compatible with the Cisco 700 series routers.

Note In the United States, telephone companies primarily provide BRI service with AT&T or Northern Telecom switches.

National ISDN-1

National ISDN-1 (NI-1) BRI switches comply with established National ISDN standards. This type of line is supported by AT&T, Northern Telecom, and other manufacturers' switches.

Note Switches that comply with the NI-1 standard provide the best performance with the Cisco 700 series voice priority feature. If possible, order this type of BRI line from your service provider.

AT&T 5ESS Custom

AT&T 5ESS switches can run in custom mode in addition to NI-1 mode.

Custom mode allows the switch to be configured to operate in either a point-to-point or a multipoint configuration. Point-to-point configuration supports one piece of terminal equipment on the BRI line and does not require Service Profile Identifiers (SPIDs). Multipoint configuration supports multiple pieces of terminal equipment on the same BRI line and requires SPIDs.

Note When ordering an AT&T 5ESS ISDN line to support multiple voice calls, provision the line for call appearances 1 and 2.

Northern Telecom DMS-100

Northern Telecom DMS-100 switches primarily follows the NI-1 specifications. This switch also supports a custom mode that is primarily used with older terminal equipment.

Note The NI-1 and DMS switch settings on the Cisco 700 series routers are equivalent.

National ISDN Capability Packages

The National ISDN User's Forum (NIUF) and Bellcore have established NI-1 capability packages for ISDN BRI line ordering. A capability package is a set of standardized BRI line features that can be ordered together in order to simplify the process of configuring an ISDN line. The capability package ordering codes described in this section apply on to NI-1 ISDN lines.

Not all service providers offer NI-1 capability packages. However, if the service provider in your area offers them, this section describes which package to order for your Cisco 700 series routers.

Note The Cisco 765 and the Cisco 766 require two SPIDs in order for the analog telephone ports to operate correctly.

Capability Package M

The preferred NI-1 capability package for the Cisco 751, Cisco 752, Cisco 761, and Cisco 762 is package M. This package provides alternate voice and circuit-switched data on both B channels. The data and voice capabilities include calling number identification.

Capability Package K

The preferred NI-1 capability package for the Cisco 753, Cisco 765, and Cisco 766 is package K. This package provides alternate voice and circuit-switched data on the first B channel and circuit-switched data only on the second B channel. Data capabilities include calling number identification.

Package K supports the Cisco 753, Cisco 765, and Cisco 766 routers' voice priority feature. Voice priority enables the user to prioritize analog phone calls when using one B channel for data/voice. Because only one directory number can be used for voice calls, voice priority must be configured on the data/voice B channel.

Package K provides the following non-EKTS voice features:

Flexible calling
Additional call offering
Calling number identification

If your service provider does not offer NI-1 capability packages or if you are not using an NI-1 ISDN line, you must order your ISDN line configured as described in the appropriate section in this appendix.

ISDN BRI Switch Provisioning Summaries

The following section contains provisioning summaries to use when you order your ISDN BRI line. Each summary is a list of codes used by the BRI service provider when installing and configuring your line. When you order your BRI line, photocopy the appropriate summary for your BRI switch type and attach it to your order form. This will help ensure that your BRI line is ordered correctly.

Note The term provisioning refers to the features that can be ordered and configured on the ISDN BRI line before terminal equipment, such as the router, can use the features.

We recommend using the BRI switch provisions listed in the following section to support voice priority on one BRI B channel.

Table B-2 lists the definitions of terms used when indicating line provisioning.

International ISDN BRI Line Provisioning

The Cisco 700 series routers support most international ISDN BRI lines.

International ISDN BRI lines generally use one of the following switch types:

EURO-ISDN (also known as NET3)
1TR6
TPH
Nippon Telegraph and Telephone (NTT)

Note International ISDN BRI lines are not assigned SPIDs. The optional argument <spid> that is offered in some of the software commands should be ignored or omitted if you are using one of the switch types listed.

International Data and Voice Application Terminology

The data and voice applications described in the section "Data and Voice Application over ISDN BRI" earlier in this chapter might be referred to by different names depending on the service provider. The terms can differ even within the country. Some international service providers might use codes instead of names to refer to the data and voice applications.

Table B-12 lists the names and codes that might be used outside of the United States to refer to the data and voice applications described in the section "Data and Voice Application over ISDN BRI" earlier in this appendix.

EURO-ISDN ISDN BRI Switch Type

The EURO-ISDN switch type, also known as NET3, is used in Europe, including the United Kingdom, France, and Germany.

Use the show version command to verify that the software loaded on your Cisco 700 series routers is ISDN Stack Revision NET3 2.10. If the correct software is not loaded on your router, contact your customer service representative.

1TR6 ISDN BRI Switch Type

The 1TR6 switch type is used in Germany.

Use the show version command to verify that the software loaded on your Cisco 700 series router is ISDN Stack Revision 1TR6 2.10. If the correct software is not loaded on your router, contact your customer service representative.

Multiple Subscriber Numbers with 1TR6

The 1TR6 lines can be configured for multiple subscriber numbers, usually referred to as "extended addressing" in Germany. The line is usually assigned a group of eight sequential directory numbers that can be used for the different pieces of terminal equipment used on the BRI line. These numbers are also used for allocation to the analog telephone port and for call routing.
