If your router has not been preconfigured, usually you can configure your router by filling out the forms provided in the Cisco 700 Quick Reference Guide and following the instructions in the Cisco Fast Step Setup application. The Cisco Fast Step Setup application takes advantage of the Cisco 700 series router's ability to detect the switch type and SPID information. However, there might be cases where you need detailed information to complete the configuration.
This appendix provides detailed information to help you order and configure the Integrated Service Digital Network (ISDN) Basic Rate Interface (BRI) line to operate with your Cisco 700 series router.
Both the ISDN line configuration and the router configuration are dependent on the switch type used. Switches that comply with the NI1 standard provide the best performance with Cisco 700 series routers.
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.
Table C-1 describes the data and voice application features.
| Feature | Description |
|---|---|
Provides locally addressed terminals within a specific ISDN access area. | |
Enables use of terminal equipment that supports voice applications. Examples of this type of equipment are ISDN telephones and terminal adapters. | |
Enables the use of multiple directory numbers on the same ISDN line. Each piece of terminal equipment on the same ISDN line can then be assigned its own directory number. | |
Enables a call in progress to be put on hold and then retrieved. | |
During a voice call, enables the call waiting tone to be generated when a second voice call is received. | |
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 switch types commonly found inside North America that are compatible with Cisco 700 series routers.
National ISDN-1 (NI1) switches comply with established National ISDN standards. This type of line is supported by AT&T, Lucent, Northern Telecom, and other manufacturers' switches.
Lucent 5ESS switches can run in custom mode, in addition to NI1 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 ISDN line and does not require Service Profile Identifiers (SPIDs). Multipoint configuration supports multiple pieces of terminal equipment on the same ISDN line and requires SPIDs.
Northern Telecom DMS-100 switches support a custom mode used with older terminal equipment.
Cisco 700 series routers support most international switch types. International ISDN lines generally use one of the following switch types:
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 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 ISDN line. These numbers are also used for allocation to the analog telephone port and for call routing.
The data and voice applications described in the section "Data and Voice" earlier in this appendix might be referred to by different names, depending on the service provider and your location. 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 C-2 lists the names and codes that might be used outside North America to refer to data and voice applications.
| North AmericaName | Other Names | Code |
|---|---|---|
Call hold and retrieve | Call hold | CH HOLD |
Call waiting | Anklopfen1 | CW |
SDA MSN |
| 1Germany only. 2France only. |
A capability package is a set of standardized features that simplifies the process of configuring an ISDN line. The capability package ordering codes described in this section apply to NI1.
Package EZ-1 (also referred to as Capability Package U) provides alternate voice and circuit-switched data with all the features and capabilities of the router enabled. Package EZ-1 is the preferred NI1 capability package for the Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers. The features include flexible calling (conference calling, call transfer, call hold and retrieve), ACO (call waiting), and Call Forward Busy (CFB).
If you have any problems with your NI1 provisioning, contact Cisco ISDN Support Services (United States 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.
We recommend using the switch provisions listed in the following section to support voice priority on one B channel.
Table C-3 lists the definitions of terms used when indicating line provisioning.
| Term | Definition |
|---|---|
CSD | Circuit-switched data---Number of B channels that can be simultaneously connected for circuit-switched data calls. |
CSD CHL | Circuit-switched data channel---B channel(s) used for data calls. |
CSD LIMIT | Circuit-switched data limit---Number of data calls that can be made simultaneously. |
CSV | Circuit-switched voice---Number of B channels that can be simultaneously connected for voice calls. |
CSV ACO | Circuit-switched voice additional call offering---Indicates an additional call when the B channel is being used. |
CSV CHL | Circuit-switched voice channel---B channel(s) that will be used for voice calls. |
CSV LIMIT | Circuit-switched voice limit---Number of voice calls that can be made simultaneously. |
CSV NBLIMIT | Circuit-switched voice notification busy limit---Number of additional voice calls allowed. |
EKTS | Key system option---Whether or not a key system is being used. (A key system is a system in which multiple telephone numbers are shared across terminals.) |
MAXB CHL | Maximum B channels---Number of B channels that can be used simultaneously. |
MTERM | Maximum terminals---Number of terminals active on the ISDN line. |
TERMTYP | Terminal type---Terminal type used on the ISDN line. Valid types for NI1 switches are Type A and Type C. |

This section is a list of configuration requirements for Cisco 700 series routers when using specific switch types. After your ISDN line is ordered and installed, if your router does not automatically detect the switch type, you can use the configuration information in this section to configure your Cisco 700 series router.
