1 IP Enabling Ericsson MD110 with Avaya Configuring a PRI Trunk Connection between an Avaya S8300 Media Server and an Avaya G700 Media Gateway running Avaya MultiVantage Software and an Ericsson MD110 (Release BC9) ABSTRACT Many multi-location enterprises have telecommunications equipment from vendors that do not provide a gentle migration path to IP converged platforms. Avaya s Enterprise Class IP Solutions (ECLIPS) enable a gradual adoption of IP technology for Third-party PBXs and enables the adoption of the valueadded capabilities of Avaya s MultiVantage Software while providing a platform to host future applications that will further enhance the enterprise s operations. Following the instructions in these Application Notes facilitate the Gentle- Migration of an Ericsson MD110 PBX to the Avaya ECLIPS platform running the Avaya MultiVantage Software for call processing. A minimal amount of new hardware is needed to complete the migration including the Avaya S8300 Media Server, the Avaya G700 Media Gateway, Avaya IP telephones and the new Avaya GUI administration tools. This solution s return on investment (ROI) is very high because it does not require a fork-lift removal of existing hardware, capitalizes on existing phone assets and the users knowledge of the existing user interface, and allows the enterprise to migrate only those users who can best utilize the productivity enhancing features of the Avaya MultiVantage Software. The platform can expand to accommodate the entire enterprise s organization over time at a pace the customer dictates. 1

2 1. Introduction The configuration shown in figure 1 illustrates an ISDN PRI Trunk Connection between an Avaya S8300 Media Server and an Avaya G700 Media Gateway (S8300/G700) running Avaya MultiVantage Software placed as an adjunct to an Ericsson MD110. The main Central Office connection for the solution is made through the MD110. Additional Central Office lines can be connected to the S8300/G700 in order to facilitate the use of Avaya Extension to Cellular (EC500) and other Avaya MultiVantage Software features. This document assumes the reader has a basic knowledge of programming Multivantage and MD110 platforms. Basic interoperability between S8300/G700 and MD110 and how it was accomplished is described within these application notes. It should be noted that the interoperability of the S8300/G700 and MD110 is established on basic network fundamentals, and more advanced areas of networking and call routing such as QSIG, AAR and ARS, while functional in this configuration, are not within the scope of this document.

SLP : This program unit deals with the following functions: - Operation and Maintenance functions. - Layer 3 protocol call control process. - Conversion of ISDN-messages into signals to the program unit TLP60. - Conversion of signals received from TLP60 into ISDN-messages. - Sending/Receiving signals to/from the TLU64, TLU76, TLU79 and VCU line interface. ADEP : This program unit supports SLP60 with decoding of IMPORTANT supplementary services according to ECMA/ETSI Generic Functional protocol. Hardware: Note: Check hardware compatibility with software version 1. TLU 76/1 PRI circuit pack. 2. ELU 76/1 digital line circuit pack. 4

5 4. Cable schematic Note: A length of 4-wire cable is needed to make the connection to each PRI circuit card. The Pin assignments for each are as follows: Ericsson MD110: 120 Quarter Connector on TLU76/1 Avaya S RJ48C TXD+ pin 1 RXD + pin 4 TXD - pin 2 RXD- pin 5 5

6 5. S8300/G700 Configurations The following pages are excerpts of an actual system administration session using the Avaya VisAbility Software Suite. DS1 Interface: ISDN maximizes the number of connections between the switches due to the fast processing of calls across that medium. ISDN also allows for Caller ID, Call Tracing, Call Return and many other features. Configure the DS1 form as described below. Select isdn-pri for the Signaling Mode, this allows for Facility and Non-facility Associated Signaling. Select hdb3 for the line coding which is required when running ISDN. Setting the Connect field to Network indicates that this connection is emulating a PSTN trunk. The Protocol field is set to etsi for Euro-ISDN protocol. display ds1 01v4 DS1 CIRCUIT PACK Location: 001V4 Bit Rate: Name: MD110 Line Coding: hdb3 Signaling Mode: isdn -pri Connect: network TN-C7 Long Timers? n Country Protocol: etsi Interworking Message: ALERTing Protocol Version: b Interface Companding: alaw CRC? n Idle Code: DCP/Analog Bearer Capabil ity: 3.1kHz Slip Detection? y Near -end CSU Type: other Figure 2. MM710 DS1 Media Module Administration Trunk Group: Create a Trunk Group and select isdn as the Group Type and a TAC number based on your switches dial-plan.

Trunk Group Administration Trunk Group Members: Assign trunk ports to the Trunk Group. Up to 255 ports can be assigned to each ISDN Trunk Group. The Sig Grp prompt will display the signaling group after you create and assign the Trunk Group to the Signaling Group. Signaling Group: Create a Signaling Group for the PRI D-channel. The Group Type default is isdn-pri ; this creates a channel to control the Bearer channels on the E1 card. Select the E1 port that will be used as the Primary D-channel and assign the Trunk Group for Channel Selection. All other prompts are default. display signaling - group 1 SIGNALING GROUP Page 1 of 5 Group Number: 1 Associated Signaling? y Max number of NCA TSC: 0 Primary D - Channel: 001V416 Max number of CA TSC: 0 Trunk Group for NCA TSC: Trunk Group for Channel Selection: 1 Supplementary Service Prot ocol: a Figure 4.

It is assumed that all features that are supported by these standards will work. 8. Conclusion This solution provides a means by which customers with traditional TDM based PBX communications networks, like the Ericsson MD110, can become IP Enabled without completely replacing their whole infrastructure. Enabling a gradual migration to a converged solution facilitates opportunities for enterprises using non-avaya solutions to get familiar with applications and administration of the new Avaya platforms gradually. Enhancements to the enterprise network and the addition of services for new employees can be added to the new Avaya platform as the business needs continue to spawn opportunities for incremental change.
