Feature Overview

The Basic Network Loopback Test for NCS/MGCP Endpoints feature in Release 4.4 provides a testing device with the capability to perform network loopback tests from any line side NCS/MGCP Residential Gateways or Media Termination Adapters (MTAs). These loopback tests are initiated from designated test endpoints (subscribers) controlled by the Cisco BTS 10200 Softswitch.

Restrictions

Although you can test this feature using the regular MTA as the testing device by configuring the endpoints as subscriber terminations in Cisco BTS 10200 Softswitch, you need special test equipment such as BRIX if voice quality testing needs to be done.

You should configure the testing and tested devices on the same Call Agent. The Cisco BTS 10200 Softswitch cannot perform network loopback test calls that originate from another switch and does not route calls from a testing device on H.323 or SIP interface.

Note You cannot perform the Network Loopback Test if the status of the subscriber to be tested is unequipped (UEQP) or operational-out-of-service (OOS).

Installing

There are no new, modified, or deleted requirements for installation procedures for the Cisco BTS 10200 Softswitch as a result of this feature. (Installation procedures include hardware installation, cabling, jumpstart, application installation, software upgrade, and hardware upgrade.)

Configuring

To configure the originating line (media gateway profile) for the testing device, use the following procedure:

Step 1 Configure the media gateway for the testing device as RGW (residential gateway): 

MGW-PROFILE::TYPE=RGW

Step 2 Associate the media gateway to the MGW-PROFILE specific to network loopback test origination: 

MGW-PROFILE::SPARE2-SUPP=Y

Step 3 Configure all test lines in the testing device as subscriber terminations.

Configuration Examples

The following example describes the steps required to configure the originating line (media gateway profile) to identify a network loopback call.

Note These tasks include examples of CLI commands that illustrate how to provision the specific feature. Most of these tables have additional tokens that are not included in the examples. For a complete list of all CLI tables and tokens, see the Cisco BTS 10200 Softswitch Command Line Interface Reference Guide.

 
Command or Action
Purpose

Step 1 

Configure the basic office database (such as Call-Agent; POP; Office).

 

Step 2  

Enter the following CLI commands:

add mgw-profile id=mta1; SPARE2-SUPP=Y;

add mgw id=brix; mgw-profile=mta1; tasp-addr=mta.abc.com; call-agent-id=CA146


Configures the MGW as a testing device.

Note "brix" is an example of a test equipment that can be used.

Step 3  

Enter the following CLI commands:

add termination prefix=aaln/s1/; port-start=1; port-end=2; type=LINE; mgw-id= brix;

add subscriber-profile id=dp5; dial-plan-id=dp1; pop-id=1;

add sub id=Abc; category=INDIVIDUAL; name=ABC; status=ACTIVE; billing-dn= 555-123-4567; ring-type-dn1= 1; term-id=aaln/S1/1; sub-profile-id=dp5; mgw-id=c2421;


Where:

•brix is an example of a test equipment

•555-123-4567 is an example of a subscriber number

Configures the test originating subscriber lines on the testing device.

Note If you want calls to terminate on the subscriber testing device, you must assign dn1 when the subscriber is provisioned, as shown in the following example:

dn1= <subscriber number>

Operating

This section describes how to use this feature.

Using/Operating the Network Loopback Test for NCS/MGCP Endpoints

To use this feature place a call from the testing device subscriber to any MGCP subscriber to be tested. For example, if the testing device is an MGCP telephone, dial the number of the subscriber to be tested.

Billing Fields

There are no new, modified, or deleted billing fields related to this feature.

For the test call, the CALLTYPE billing field will show TEST_CALL.

Note See the Cisco BTS 10200 Softswitch Billing Guide for detailed information regarding billing fields.
