Laurel Introduces New ST200 Service Edge Router Interface Cards; 12-port Clear Channel and Channelized DS-3/E3 Cards Further Expand ST200 Flexibility.Business Editors PITTSBURGH--(BUSINESS WIRE)--March 16, 2004 Laurel Networks, Inc., the first provider of high-performance service edge routers, today announced the availability of 12-port channelized Refers to an architecture that transmits data in channels. It often refers to the 64 Kbps channels in T1 lines, which were originally developed to handle digitized voice streams (TDM). See TDM. and clear channel DS-3/E3 electrical physical interface (PHY) cards for the ST200(TM) Service Edge Router. The new PHYs are ideal for carriers requiring electrical-based dedicated access connections, and complement ST200 optical interfaces supporting speeds from 64 Kbps to OC-192. The 12-port channelized DS-3 card provides physical DS-3 connectivity and supports a combination of up to 1,024 NxDS-0, 336 T1 and 12 DS-3 channels. The 12-port clear channel DS-3/E3 card supports 12 clear channel DS-3 or E3 ports. ST200 Electrical PHYs Provide AnyService on AnyPort @ AnySpeed(TM) Both new cards feature Laurel's industry-leading QoS (quality of service) capabilities and the flexibility to configure AnyService on each channel including Point-to-Point Protocol (PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using ), High-level Data Link Control (networking) High-level Data Link Control - (HDLC) A general-purpose data link control protocol defined by ISO for use on both point-to-point and multipoint (multidrop) data links. It supports full-duplex, transparent-mode operation. (HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. ), Frame Relay, Asynchronous Transfer Mode See ATM. (communications) Asynchronous Transfer Mode - (ATM, or "fast packet") A method for the dynamic allocation of bandwidth using a fixed-size packet (called a cell). See also ATM Forum, Wideband ATM.

(ATM), Multilink PPP (RFC 1990), Multilink Frame Relay (FRF FRF The ISO 4217 currency code for the French Franc. .16), Inverse Multiplexing over ATM (IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting ), Bridging Control Protocol (BCP) and broadband (PPPoX). This flexibility reduces sparing costs, eliminates stranded ports and enables interface reuse as access network technologies change and bandwidth demands increase. "With the introduction of electrical DS-3 interfaces, we continue to expand the capability of our ST200 Service Edge Router," said Steve Vogelsang, VP of marketing and co-founder of Laurel Networks. "Like our other multi-service cards, the DS-3 cards leverage the flexible ST200 architecture to deliver AnyService on AnyPort @ AnySpeed, resulting in reduced initial and ongoing costs for service providers." Availability ST200 12-port clear channel and channelized DS-3/E3 cards are available in Q2, 2004. About Laurel Networks Laurel Networks is leading the creation of The New Service Delivery Architecture to enable profitable delivery of data and IP services at the edge of carrier IP/MPLS IP/MPLS Internet Protocol/Multi-Protocol Label Switching networks. Laurel's service edge routers and service management software are evolving carrier architectures from multiple data networks to a single packet-switched architecture with minimal capital investment. Combining carrier-class routing, data switching, advanced QoS and high availability, Laurel service edge routers support both routed and switched services. This unmatched service agility allows carriers to evolve their service portfolio to meet changing market requirements. Laurel Networks was founded in 1999 and is headquartered in Pittsburgh, Pennsylvania. For more information, visit www.laurelnetworks.com. |
