AGILENT Technologies has announced support for SONET/SDH Link Capacity Adjustment Scheme (LCAS) at both high and low-order virtual concatenation levels for its OmniBER OTN J7232A 2.5Gb/s analyser.
Along with its Generic Framing Procedure (GFP) encapsulation support the J7232A gives designers and verification engineers of SONET/SDH multi-service provisioning platform (MSPP) equipment the ability to fully check design conformance to industry standards.
This helps to ensure full interoperability of next-generation data services across vendor platforms.
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 10Gb/s rates of OC-192 and STM-64.
Equipment manufacturers and service providers are driving the introduction of next-generation SONET/SDH capability at 10Gb/s 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 (55Mb/s and 155Mb/s) are grouped when transporting high-speed data services such as Gigabit Ethernet and fiber channel. Low-order containers (1.5Mb/s or 2Mb/s) are used for low-speed data services such as 10Mb/s or 100Mb/s 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.
