Ascend to unveil edge interfaces for ATM core switchinfoworld.com By Stephen Lawson InfoWorld Electric Posted at 4:09 PM PT, Feb 5, 1999 In a move that will begin to position its CBX 500 ATM core switch as an edge device for competitive service providers, Ascend on Monday will introduce channelized Frame Relay and IP interface modules for the platform. The interfaces -- which can provide T1 and DS-0 connectivity to enterprises -- are designed to let carriers and ISPs offer voice-over-IP service, low-speed frame relay, or T1 services that carry both data and voice. Also this week, at the IP Multicast Summit, in San Jose, Calif., Ascend will demonstrate IP Multicast for the first time on the CBX 500, GX 550, and B-STDX9000 ATM core switches. The switches will route IP Multicast traffic across an ATM infrastructure using the Multiprotocol Label Switching standard. The IP Multicast support will be available this summer, officials said. Ascend last month agreed to a merger with Lucent Technologies in a deal valued at approximately $20 billion. Lucent sought out Ascend in order to gain a share of data WANs, which are expected to begin carrying much of the voice traffic that currently runs over Lucent's traditional equipment. Ascend is a leading vendor of equipment for Internet service provider networks. The company's CBX 500 switch has been installed in the core of ISP networks and features interfaces ranging to as much as OC-12 (622Mbps). Officials said that service providers now upgrading their cores to the Ascend GX550 series -- which can accommodate OC-48 (2.4Gbps) interfaces -- can deploy the CBX 500 switches at the edge of the network. Each interface module will feature four T3 (45Mbps) ports, channelized into either T1 (1.5Mbps) or DS-0 (64Kbps) connections. This will allow for 1,568 T1s in a 14-slot rack. Also this week, Ascend will announce features designed to increase the reliability of the CBX 500. Most important is rapid upgrade capability, which will allow service providers to replace hardware or upgrade software on a switch without interrupting service to customers. Ascend officials said the feature may allow ISPs to offer new services more often and more quickly, because they will not have to schedule network downtime to activate the changes. The CBX 500 interface modules are priced at approximately $134,400 per module, or $164 per DS0 interface. The reliability features are available now with new models of the CBX 500.
