High-Density 32-Channel T1/E1/J1 Framer with Integrated
VT/TU Mapper & M13 Multiplexer
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.
PRODUCT HIGHLIGHTS
This monolithic device integrates:
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.
Flexible line-side and system-side interface support:
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 system-
side 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.
