| PM8312 TEMUX 32 High-Density 32-Channel T1/E1/J1 Framer with Integrated VT/TU Mapper & M13 Multiplexer Released Product Brief PRODUCT OVERVIEW The PM8312 TEMUX 32 device is a 64-Mbit/s multi-channel T1/E1 framer with an integrated VT/TU Mapper and M13 Multiplexer. * Flexible line-side and system-side interface support: * PRODUCT HIGHLIGHTS * This monolithic device integrates: * * * Supports a 19.44-MHz Scaleable Bandwidth Interconnect (SBITM) Interface for high-density line-side device interconnection to PMC-Sierra's T1/E1 line interface products, including the 8-port PM4323 OCTLIU LT and the 32-port PM4329 HDLIU. Provides a 19.44 or 77.76 MHz SONET/SDH Add/Drop Telecom bus interface for seamless connection with PMC-Sierra's SONET/SDH devices. Supports a byte-serial Scaleable Bandwidth Interconnect (SBI) interface at 19.44 MHz or 77.76 MHz for high-density systemside device interconnection to PMC-Sierra's link layer products. Supports 8 Mbit/s H-MVIP system interface for all T1 or E1 links, a separate 8 Mbit/s H-MVIP system interface for all T1/E1 CAS channels, and a separate 8 Mbit/s H-MVIP system interface for all T1 or E1 CCS and V5.1/V5.2 channels. Supports 28 T1 or 21 E1 links in DS3 mode and up to 32 T1 or E1 links when using the line-side SBI interface or SONET/SDH mode. Supports transparent virtual tributaries when the SBI interface is used with a SONET/SDH mapper. Supports insertion and extraction of arbitrary rate (e.g. fractional DS3) data streams to and from the SBI bus interface. * 32 T1 framers. 32 E1 framers. One SONET/SDH VT1.5/VT2/TU11/TU12 bit asynchronous or byte synchronous mapper. One full-featured M13 multiplexer with DS3 framer. One SONET/SDH DS3 mapper for terminating unchannelized DS-3 or DS3-multiplexed T1/E1 streams. * * * * * * Supports a wide range of T1, E1 and J1 framing formats. * Supports DS3 framing modes such as M23, C-bit parity, and ITU-T Recommendation G.747. * Stand-alone unchannelized E3 framer mode (ITU-T Rec. G.751 or * G.832) for access to the entire E3 payload. * BLOCK DIAGRAM 19.44 MHz Line-Side Scaleable Bandwidth Interconnect Bus or 19.44/77.76 MHz Telecom Bus Mapper and Telecom Bus I/F M13 Mux RJAT T1/E1 Framer PMON PRBS 32xT1 / 32xE1 on 11 H-MVIP buses Scaleable Bandwidth Interconnect Bus 19.44/77.76 MHz DS3/E3 Interface DS3/E3 Framer with PRBS TJAT T1/E1 Transmitter DS3/E3 Clock and Data PMC-2051525, Issue 2 (c) Copyright PMC-Sierra, Inc. 2006 All rights reserved.
