Avaya Solution & Interoperability Test Lab Application Notes for Configuring Avaya Communication Manager T1 and FXO/FXS Analog Private Lines over a Lucent Technologies Metropolis DMXtend SONET Ring Issue 1.0 Abstract These Application Notes describe the procedures for configuring Avaya Communication Manager T1 and FXO/FXS analog private lines transported over a SONET ring composed of Lucent Technologies Metropolis DMXtend Access Multiplexers. The DMXtend Access Multiplexer is a SONET multiplexer that enables the transmission of traditional voice/tdm and private line services, and data services over SONET. In the compliance tested configuration, a T1 private line connects two Avaya Communication Manager systems located in two different sites, and a FXO/FXS private line connects analog telephones in a remote site back to Avaya Communication Manager in a main site. During compliance testing, telephone calls traversing the T1 and FXO/FXS private lines were successfully completed and also maintained after UPSR protection switching occurred in the ring. Information in these Application Notes has been obtained through compliance testing and additional technical discussions. Testing was conducted via the DeveloperConnection Program at the Avaya Solution and Interoperability Test Lab. 1 of 28

1. Introduction These Application Notes describe a compliance-tested configuration comprised of Avaya Media Servers, Avaya Media Gateways, and Lucent Technologies Metropolis DMXtend Access Multiplexers. The DMXtend Access Multiplexer is a SONET multiplexer that enables the transmission of traditional voice/tdm and private line services, and data services over SONET. These Application Notes focus on the configuration of T1 (ISDN PRI and E&M Wink Start) and FXO/FXS private lines that are connected to Avaya Communication Manager systems and transported over a SONET ring formed by DMXtend Access Multiplexers. Figure 1 illustrates a sample configuration consisting of: an Avaya S8500 Media Server, an Avaya G650 Media Gateway, an Avaya S8300 Media Server residing in an Avaya G350 Media Gateway, Avaya IP Telephones, Avaya Digital Telephones, and analog telephones, Lucent Technologies DMXtend Access Multiplexers, and Adtran Atlas 550 Integrated Access Devices (IADs). Avaya Communication Manager runs on the S8500 Media Server and S8300 Media Server, though the solution described herein is also extensible to other Avaya Media Servers and Media Gateways. The Avaya S3400 Modular Messaging servers and the Extreme Networks Alpine 3808 Switch in Figure 1 are not the focus of these Application Notes, and are not described here. The network illustrated in Figure 1 is divided into three sites that are interconnected by a SONET ring. Site A and Site B contain independent Avaya Communication Manager systems, each with their own dial plans and extensions. A T1 line connects the S8500 Media Server in Site A and the S8300 Media Server in Site B, and is transported over the SONET ring. Site C contains analog telephones that are remoted stations of Avaya Communication Manager in Site A. The remoted analog telephones connect to the FXS interface ports of the Atlas 550, which in turn multiplexes the FXS interface ports onto DS0 channels in a T1 line. The T1 line is transported over the SONET ring between Site A and Site C. The Atlas 550 in Site A demultiplexes the DS0 channels onto FXO interface ports, which in turn connect to analog ports on the G650 Media Gateway. In this document, the T1 line between Site A and Site C is referred to as an FXO/FXS line to differentiate it from the T1 ISDN-PRI and E&M Wink Start lines between Site A and Site B. 2 of 28

6. Interoperability Compliance Testing The interoperability compliance testing focused on verifying site-to-site connectivity and interface compatibility. 6.1. General Test Approach The general approach was to place calls between sites over the T1 and FXO/FXS lines transported over the SONET ring. The main objectives were to verify that: Calls between Site A and Site B, between Site A and C, and between Site B and Site C are successfully completed and maintained. Calls between each site and the PSTN are successfully completed and maintained. When Unidirectional Path Switched Ring (UPSR) protection switching occurs on the SONET ring, active calls between sites are maintained. Calls between sites are successfully completed and maintained after recovering from failures such as T1 cable disconnects, busyouts/releases and resets of the DS1 circuit packs on the G650 and G350 Media Gateways, and resets of the DS1 circuit packs on the DMXtend Access Multiplexers. A remoted analog telephone user in Site C successfully retrieves voice mail from the Avaya Modular Messaging servers in Site A.
