GENERAL DESCRIPTION:
VSC9125 (HOVCAT48e) is a 2.488 Gbps,
multiservice, SONET/SDH data mapping device that supports both contiguously concatenated as well as virtually concatenated transport channels. A maximum of 48 data channels can be mapped into transport channels. Fully integrated Link Capacity Adjustment Scheme (LCAS) protocol is implemented. For route-diverse applications, external memory can accommodate differential delays up to 128 ms between tributaries. Frame-based Generic Framing Procedure (GFP-F), transparent Generic Framing Procedure (GFP-T), PPP/HDLC-like (PoS, LAPS) framing, and PPP/BCP (Bridge Control Protocol) are mapped into the SONET/SDH transport channels. The interface to these data channels is through SPI-4.2, system/packet interface. HOVCAT48e supports both a backplane interface and a line interface. The backplane interface can be configured as dual (working and protection) 2.5 Gbps serial STS-48/STM-16-like streams or quad (working and protection) 622 Mbps serial STS-12/STM-4-like streams for interfacing to STS-1 TSI switches. Fully programmable SONET/SDH Section, Line, and Path termination and generation is supported. External ports provide access to the entire Section/Line and Path overhead. VSC9125 BLOCK DIAGRAM:
