13 January 2004 Palo Alto, CA Lightwave--Agilent Technologies today announced support for SONET/SDH link capacity adjustment scheme (LCAS) at both high- and low-order virtual concatenation levels for its OmniBER OTN J7232A 2.5-Gbit/sec analyzer. The J7232A now gives designers and verification engineers of SONET/SDH multi-service provisioning platform (MSPP) equipment the ability to fully check design conformance to industry standards, thereby ensuring full interoperability of next-generation data services across vendor platforms. LCAS is a key enabler of flexibility in next-generation SONET/SDH data services by providing dynamically variable transport bandwidth to end-users.
In addition, the new OmniBER OTN J7230B product is the first to offer the complete next-generation SONET/SDH test portfolio (including data mappings, GFP encapsulation, high- and low-order virtual concatenation and LCAS) at the 10-Gbit/sec rates of OC-192 and STM-64. Equipment manufacturers and service providers are driving the introduction of next-generation SONET/SDH capability at 10 Gbits/sec in support of flexible Gigabit Ethernet and high-speed fibre channel data applications (including storage area networks). The J7230B also offers support for ITU-T G.709 Optical Channel and all legacy SONET/SDH standards.
Next-generation SONET/SDH is the term applied to recent enhancements and additions to SONET/SDH standards and equipment that enable data services to be carried more efficiently and flexibly. Three new technologies are key to next-generation SONET/SDH:
• GFP encapsulation adapts Ethernet, fibre channel and other data traffic for suitability to a constant bit-rate carrier.
• Virtual concatenation enables SONET/SDH transport pipes to be filled more efficiently with data services by grouping individual SONET/SDH containers into a virtual high-bandwidth link, matched to the required service bandwidth. High-order virtual concatenation containers (55 Mbits/sec and 155 Mbits/sec) are grouped when transporting high-speed data services such as Gigabit Ethernet and fiber channel. Low-order containers (1.5 Mbits/sec or 2 Mbits/sec) are used for low-speed data services such as 10-Mbit/sec or 100-Mbit/sec Ethernet.
• LCAS further enhances the flexibility of SONET/SDH virtual concatenation transport by enabling the addition and removal of virtual link containers in response to an identified change in service bandwidth requirement, or in response to a fault condition in an existing container.
"LCAS is the latest significant building block in the provisioning of next-generation data services by SONET/SDH," said Richard Deboer, chief executive of Galazar Networks, a fabless semiconductor company that delivers carrier-grade, multi-service, Ethernet and data service framers for highly channelized service applications. "LCAS is the most complex, in terms of the protocol 'hand-shaking' between source and destination equipment, therefore stringent interoperability testing was required before our customer could be selected as preferred supplier for next-generation networks. With the ability to fully emulate the operation of a SONET/SDH LCAS terminal, the OmniBER OTN provides an independent validation of MSPP design conformance to industry standards, highlighting at an early development stage any possible interoperability issues."
