| NETWORK PRODUCTS VSC9115 2.5 Gb/s Multi-Service SONET/SDH Mapper Device with Virtual Concatenation BENEFITS: Allocated bandwidth for each data channel can be dynamically changed, without interrupting the traffic, utilizing the Link Capacity Adjustment Scheme (LCAS) to signal bandwidth changes to the receiving end. This makes the VSC9115 well suited for carrying multiple varying data flows from different customers with excellent bandwidth allocation granularity and efficiency. Available data channels or payloads can be shared among any number of the possible maximum 48 transport channels by utilizing contiguous concatenation and/or Virtual Concatenation at AU-4/TU-3/VC-3, STS-1/VC-3, or STS-3c/VC-4 levels. F E AT U R E S : 48 STS-1/VC-3, 48 TU-3/VC-3, or 16 STS-3c/VC-4 Virtual Concatenation Groups Link Capacity Adjustment Scheme (LCAS) with Hitless Adds and Removes, and Fault Isolation External DDR 64 bit SDRAM for Diverse Routing Applications with Differential Delays of up to 108 ms Flexible Payload Processing for Generic Framing Procedure (GFP) with Support for Several Interfacing Formats including Ethernet Frames Supports HDLC-Like Framing: PoS - RFC2615, LAPS - X.85, and X.86 System Packet Interface Level 4 (SPI-4), Phase 2, 16-Bit Interface Dual 2.5 Gb/s Serial, STS-48/STM-16-like Backplane Interfaces or Dual 4 x 622 Serial STS-12/STM-4-like Backplane Interfaces with Performance Monitoring for Connection to Working and Protection TSIs Two-Level Pointer Generation and Interpretation for SDH Mapping of TU-3/VC-3 into AU-4 Channelized Payload Mapping into AU-4/TU-3/VC-3, STS-1/VC-3, STS-3c/VC-4, STS-12c/VC-4-4c, STS-48c/VC-4-16c, or Virtual Groups Composed of AU-4/TU-3/VC-3s, STS-1/VC-3s, or STS-3c/VC-4s Extensive Performance Monitoring Features A P P L I C AT I O N S : Point-to-Point Linear Configurations Such as a Multi-Service Router/ Switch or Point-to-Point Transport SONET/SDH ADM and TSI Switching Systems Gigabit Ethernet Transport Applications Utilizing LAPS or GFP Frame Encapsulations Point-to-point Packet-over-SONET (PoS) Router Applications Data Channels or Payloads Can be Shared Among up to 48 Transport Channels by Using Contiguous Concatenation and/or Virtual Concatenation S TA N D A R D S : ANSI T1.105, Telcordia GR-253-CORE, and ITU-T G.707 Compliant HDLC-Like Framing: PoS - RFC2615, LAPS - X.85, and X.86 OIF-SPI4-02.0 (OC-192) SPI-4.2 16-Bit Packet Interface PB-VSC9115-001 VSC9115 2.5 Gb/s Multi-Service SONET/SDH Mapper Device with Virtual Concatenation GENERAL DESCRIPTION: The VSC9115 is a 2.5 Gb/s multi-service SONET/SDH data mapping device that supports both contiguously concatenated and virtually concatenated transport channels. The AU-3/TU-3/VC-3, STS-1/VC-3, and STS-3c/VC-4 transport channels may be virtually concatenated to support larger custom transport channels. Up to 48 packet streams can be mapped into these transport channels (up to 16 for STS-3c/VC-4). Virtual concatenation of AU-3/TU-3/VC-3, STS-1/VC-3, or STS-3c/VC-4 transport channels into Virtual Groups is supported through SONET/SDH. Path Overhead H4 byte is processed for payload identifiers, types, and sequencing. Non-contiguous transport channels can be tagged and linked through these overhead bytes to form larger, custom transport channels. (LCAS) protocol is supported by processing the H4 byte control packets and reporting back member status. Flexible Payload Processing for (GFP) is supported for several interfacing formats including Ethernet Frames. It also supports HDLC-like framing: PoS - RFC2615, LAPS - X.85, and X.86 APPLICATION DIAGRAM: S P E C I F I C AT I O N S : Backplane Interface Speed: Dual 4 x 622 Mb/s Serial Packet Interface Speed Out: 830 Mb/s or 622 Mb/s (16 bits), SPI-4 Phase 2 (or 700 Mb/s w / ext ref.) Packet Interface Speed in: up to 830 Mb/s (16 bits), SPI-4 Phase 2 Virtual Concatenation Groups: Up to 48 (up to 16 for STS-3c/AU-4) CPU Asynchronous Interface: MotorolaTM and IntelTM CPU Synchronous Interface: PowerPCTM and IntelTM StrongARMTM Diagnostic Interface: IEEE 1149.1 JTAG Physical Package Configuration: 728-Pin TBGA Maximum Power Dissipation: 11 W Supply Voltages: +1.8 V and +2.5 V Temperature Range: 0 C to +85 C Ambient Your Partner for Success.
