NEC 2400 ICS Rel J 5.8 PBX with CallManager using 6608-E1 PRI EURO Gateway

Application Note

NEC 2400 ICS Rel J 5.8 PBX with CallManager using 6608-E1 PRI EURO Gateway

This application note illustrates connectivity for NEC 2400 ICS Rel J 5.8 PBX with CallManager using 6608-E1 PRI EURO Gateway.

Introduction

The network topology diagram presented in Figure 1 illustrates the test set-up for end-to-end interoperability with the Cisco CallManager connected to the PBX via 6608-E1 PRI link as the Gateway

Key test environment parameters:

•Connectivity is achieved by using the PRI EURO protocol type on the gateway and NEC/ETSI switch type on the NEC 2400 PBX. Though the NEC 2400 can be configured as either NETWORK (Master) or USER (Slave) side, this is not recommended and the NEC TAC center will not resolve a case presented with NEC set as NETWORK side.

•Calling Name delivery and presentation features are not supported by the NEC 2400 PBX.

•CCM does not send "Connected Number" information in the CONNECT message back to PBX.

Limitations

Calling Name and Number Feature

Calling Name delivery and presentation feature are not supported by the NEC 2400 ICS PBX.

When calling from Cisco 7960 IP phone to NEC digital phone, both phones display Calling Number after the call is answered as expected.

When calling from NEC digital phone to Cisco 7960 IP phone, the Cisco IP phone displays Connected Number after the call is answered. NEC phone however does NOT get updated when the call is answered. It displays the numbers being dialed instead (i.e. Access Code + extension number). It was verified using an ISDN protocol analyzer that the CCM was not sending "Connected Number" information in the CONNECT message back to PBX.

NEC 2400 ICS Configuration

The NEC requires a substantial amount of programming and circuit card switch settings to properly install E1 PRI. It is beyond the scope of this document to provide the entire configuration, therefore the NEC information below is mostly helpful for NEC techs. If further assistance is required, the entire configuration of our lab PBX can be found in EDCS document # EDCS-207455. The EDCS document provides the programs required for E1 ISDN circuit setup, all the switch settings for all cards on our Lab NEC and fairly complete configuration listings (List Ups).

Note: The switch settings and software references in the EDCS document assume a familiarity with the NEC 2400. It is highly recommended to have a NEC ISDN certified technician setup the NEC portion.

Configure in the following sequence:

1. Install circuit card.

2. Configure all software.

Route (ARTD) Configuration

Below are the Route settings found in ARTD. Route 12 is the B channel and Route 13 is the D channel. Please refer to EDCS document # EDCS-207455 for complete details for configuration.

Test Configuration

Test Topology

As shown in the diagram above, an NEC 2400 ICS PBX was connected via an ISDN E1 PRI link to a Cisco 6608-E1 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-E1 and the PBX.

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/6608-E1 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-E1 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-E1 Gateway with ISDN protocol type setting of PRI EURO supports both protocol sides by selecting "Network/User" in the Protocol Side field when configuring the Gateway via CCM. The NEC 2400 ICS PBX supports "USER" protocol side.

Test Results

Testing was performed by Test Engineer(s): Samir Batio and Bob Graves, March 11, 2002

Test Setup

Test configuration:

•PBX1 configured as ETSI, emulates User

•Cisco 6608-E1 Gateway configured as PRI EURO, emulates Network
