This appendix describes how to order and configure the Integrated Service Digital Network (ISDN) Basic Rate Interface (BRI) line to operate with Cisco 700 series routers.
Both the BRI line configuration and the router configuration are dependent on the BRI switch type used. BRI switches that comply with the NI-1 standard provide the best performance with 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:
The Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers support data and voice applications. The voice applications on these four router models are implemented with ISDN BRI and through the analog telephone port on the router.
The BRI line supports the following data and voice applications on the Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers:
The BRI line supports the following voice-only applications for these models:
Table A-1 describes the data and voice application features supported by the ISDN BRI line.
| Feature | Description |
|---|---|
| Caller ID, calling party identification | Identifies the remote system that originated the call. |
| Subaddressing | Provides locally addressed 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 765, Cisco 766, Cisco 775, and Cisco 776. |
| Multiple subscriber numbers (MSN) | 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 | During a voice call, enables the call waiting tone to be generated when a second voice call is received. |
| Call bumping | When two data calls are in progress and ACO is provisioned on the ISDN line, the router can be configured to either ignore a voice call or disconnect a data call to accept the voice call. (Also referred to as voice priority.) |
| Call transfer | Transfers an active call to another telephone number. |
| 3-way call conferencing | Adds a third party to an existing call. |
The following section describes the BRI switch types that are compatible with Cisco 700 series routers.
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.
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.
Northern Telecom DMS-100 switches support a custom mode used with older terminal equipment.
A capability package is a set of standardized BRI line features that simplify the process of configuring an ISDN line. The capability package ordering codes described in this section apply to NI-1 ISDN lines.
Package R provides circuit-switched data on both B channels (no voice capabilities). Data capabilities include Calling Number Identification. It is the preferred NI-1 capability package for Cisco 761, Cisco 762, Cisco 771, and Cisco 772 routers.
Package S provides alternate voice and circuit-switched data with no additional features. Package S is the preferred NI-1 capability package for Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers where a minimum feature set is needed.
Package EZ-1 provides alternate voice and circuit-switched data with all the features and capabilities of the router enabled. Package EZ-1 is the preferred NI-1 capability package for the Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers where a full feature set is needed. The features include flexible calling (conference calling, call transfer, hold and retrieve), ACO (call waiting), and Call Forward Busy (CFB).
If you are not using an NI-1 ISDN line, you must order your ISDN line configured as described in the "ISDN BRI Switch Provisioning Summaries" section of this appendix.
If you have any problems with your ISDN NI-1 provisioning, contact Cisco ISDN Support Services (U.S. only). To access this service or to obtain more information, call (800) 553-NETS (6387) and select the Customer Service option, or visit the Cisco ISDN web site at www.cisco.com/isdn.
The following section contains provisioning summaries to use when you order an ISDN BRI line other than NI-1. 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.
We recommend using the BRI switch provisions listed in the following section to support voice priority on one BRI B channel.
Table A-2 lists the definitions of terms used when indicating line provisioning.
Table A-3 lists the BRI provisioning summary for AT&T 5ESS Custom BRI switches.
| Line Provision | Configuration |

Cisco 700 series routers support most international ISDN BRI lines. International ISDN BRI lines generally use one of the following switch types:
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 a country. Some international service providers might use codes instead of names to refer to the data and voice applications.
Table A-11 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.
| U.S. Name | Other Names | Code |
|---|---|---|
| Caller ID, Calling party identification | Calling line identification presentation Identification d'appel1 | CLIP |
| Call hold and retrieve | Call hold | CH HOLD |
| Call waiting | Anklopfen2 | CW |
| Multiple subscriber numbers | Extended addressing Selection directe a l'arrive3 | SDA MSN |
The EURO-ISDN switch type, also known as NET3, is used in Europe and parts of Asia, including the United Kingdom, France, Germany, Singapore, and Taiwan.
Enter the show version command to verify that the software loaded on your Cisco 700 series router is ISDN Stack Revision NET3 2.10. If the correct software is not loaded on your router, contact your customer service representative.
The 1TR6 switch type is used in Germany.
Enter 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.
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.
