This document describes the Asynchronous Line Monitoring feature feature. It includes the following sections:
Feature Overview
The Asynchronous Line Monitoring feature feature removes previous restrictions on the number of dialed digits accepted as a valid telephone number in the Called Party number information element (IE) for the National or International numbering types.
Benefits
The Asynchronous Line Monitoring feature feature is a change to the Cisco IOS software that makes the ISDN dialing plan more flexible by allowing a range rather than a restricted number of digits to be accepted for dialing.
Restrictions
The Asynchronous Line Monitoring feature feature was developed for interfaces configured for network-side ISDN where the Called Party IE digits are of National or International numbering types.
Related Documents
Refer to the chapter “Configuring Network Side ISDN PRI Signaling, Trunking, and Switching” in the part “Signaling Configuration” in the Cisco IOS Dial Technologies Configuration Guide, Release 12.2, for more information about configuring network-side ISDN switches.
Supported Platforms
The Asynchronous Line Monitoring feature feature is supported on the following platforms:
Determining Platform Support Through Cisco Feature Navigator
Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.
Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.
To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:
Supported Standards, MIBs, and RFCs
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Configuration Tasks
No new commands are associated with the Asynchronous Line Monitoring feature feature. See the “Troubleshooting Tips” section for information about verifying numbering plans and switch types configured. See the “Configuration Examples” section for configuration examples.
Troubleshooting Tips
To learn and, if necessary, change the numbering plan and type currently configured on the ISDN interface, perform the following steps:
Step 1
To learn the numbering plan and type currently configured, use the debug isdn q931 command in EXEC mode:
The Called Party Number report lists the numbering plan and type.
Step 2 To change the numbering plan and type, use the isdn map command in interface configuration mode. Use the command line interface help feature to list the choices.
Step 3 To force the ISDN numbering plan and National type on the peer (calling number) side, use the isdn map command with the following keywords in interface configuration mode:
Monitoring and Maintaining Asynchronous Line Monitoring feature
To monitor and maintain the Asynchronous Line Monitoring feature feature, use the procedure in the “Troubleshooting Tips” section.
You may also find the following EXEC command useful for displaying an extensive report about the ISDN interfaces, including the switch type and the status of ISDN Layers 1 through 3:

Displays the status of all ISDN interfaces, or just the specified interface. |
Configuration Examples
This section provides the following configuration examples:
- Data Call Asynchronous Line Monitoring feature Example
- Voice Call Asynchronous Line Monitoring feature Example
Data Call Asynchronous Line Monitoring feature Example
The following example shows configurations for inserting telephone numbers with varying numbers of digits for data calls.
Figure 1 Data Call Asynchronous Line Monitoring
Voice Call Asynchronous Line Monitoring feature Example
The following example shows configurations for inserting both PBX and public telephone service telephone numbers with varying numbers of digits for voice calls. The PBX is is configured for National ISDN with numbering type National.
