VSC9128

VSC9128 (HOVCAT192e) is a 10 Gbps, multiservice, SONET/SDH data mapping device that supports both contiguously concatenated as well as virtually concatenated transport channels. A maximum of 64 data channels can be mapped into transport channels. The Link Capacity Adjustment Scheme (LCAS) protocol is supported. 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 a 16-bit OIF SPI-4 Phase 2 system/packet interface. HOVCAT192e supports both a backplane interface and a line interface. Fully programmable SONET/SDH Section, Line, and Path termination and generation is supported. External ports provide access to Section/Line and Path overhead.
