Considerations

Calling Name and Number Feature

Calling Name delivery and presentation features are supported by the Nortel PBX as of Release 25 for DMS-100 switch-type.

The Nortel Meridian Opt11C supports the USER side only when the switch type is set to DMS-100. Therefore, the Cisco 6608 Gateway should be configured to emulate the NETWORK side.

When calling from a Cisco 7960 IP phone to a Nortel digital phone, the Calling/Called Name and Number are displayed on both phones after the call is answered as expected.

When calling from a Nortel digital phone to a Cisco 7960 IP phone, the IP phone displays the Connected Name and Number after the call is answered. The Nortel phone, however, is not updated when the call is answered. It displays the numbers being dialed instead. (the access code and the extension number). It was verified using ISDN protocol analyzer that the CallManager was not sending the Connected Number information in the connect message back to PBX.

This section contains information about the setup used in testing the integration of the Nortel Meridian Opt11C Release 25 PBX and the Cisco 6608-T1 PRI DMS-100 Gateway.

Test Configuration

The following figure represents the various configurations used for testing.

Testbed Network Configuration

As shown in the figure above, a Nortel Meridian Opt 11C PBX was connected via an ISDN T1 PRI link to a Cisco 6608-T1 Gateway, which in turn, was connected to an Ethernet switch. The interoperability testing involved Layers 1, 2 and 3 on the ISDN PRI link between a Cisco 6608-T1 and the PBX.

Layer 1 (Physical Layer)

The Nortel configuration screen for the T1 trunk interface is reached using LD 17, setting the CEQU (Common Equipment parameters).

Layers 2 & 3 (Q.921 and Q.931)

Layer 2 and 3 packet exchanges were monitored using an Acacia Clarinet protocol analyzer, bridged across the PRI link in high impedance mode.

Layer 2 Q.921 packets were monitored to ensure that each PBX/2621 software configuration properly exchanged SABME/UA packets to initialize the ISDN link, and then RR packets were exchanged every 30 seconds.

Layer 3 Q.931 packets were monitored to ensure that the appropriate call setup/teardown packets were exchanged for each configuration, and that the SETUP packets contained the mandatory Information Elements with the necessary details, as well as optional IEs such as Calling Name and Number.

Telephone calls were made end-to-end in both directions through the Cisco 6608-T1 Gateway, and a check was made to ensure that there was an audio path in both directions for each call.

User/Network Settings

The Cisco 6608-T1 Gateway with ISDN protocol type setting of PRI DMS-100 supports both protocol sides by selecting "Network/User" in the protocol side field when configuring the Gateway via CallManager.

The Nortel Meridian Opt11C supports the USER side only when the switch type is set to DMS-100. Therefore, the Cisco 6608 Gateway should be configured to emulate the NETWORK side. This USER choice is set on the Nortel by using LD 17.

Test Results

Testing was performed by Test Engineer(s): Samir Batio, September 11, 2001

Test 1

In test 1:

•The PBX1 country-protocol is set to DMS-100 to emulate the Network.

•The Cisco 6608-T1 Gateway was configured as a PRI DMS-100 to emulate the User.

The results are shown in the following tables.
