VSC9125 (HOVCAT48e™) Enhanced 2.5 Gbps Multiservice SONET/SDH VC Mapper
VSC9128 (HOVCAT192e™) Enhanced 10 Gbps Multiservice SONET/SDH VC Mapper
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.
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.
