High Density T1/E1 Framer, VT/TU Mapper & M13 Mux with

Integrated SONET/SDH Framers

PRODUCT OVERVIEW

The PM8310 TEMUX 336 is a high density T1/E1, DS3/E3 framer, VT/TU

mapper, and M13 multiplexer with integrated SONET/SDH framers for

OC-12/STM-4 and 4xOC-3/STM-1 applications. Feature integration and

scalability make the TEMUX 336 ideal for use in ATCA/AMC line cards,

voice and media gateways, routers, and multi-service and edge aggre-

gation switches.

The TEMUX 336 device’s unique Extended Serial SONET/SDH Interface

(ESSI) enables:

•

A low pin-count interconnect to additional TEMUX 336 devices for

equipment protection applications

•

Higher-rate SONET/SDH framers such as the PM5336 ARROW 2488

for channelized OC-48/STM-16 designs

•

SONET/SDH cross-connects in transport applications

•

Ethernet over SONET/SDH mappers such as the PM4390

ARROW M8xFE

Additionally, the device’s Scalable Bandwidth Interconnect (SBI) bus

enables a simple interconnect to PMC-Sierra Layer 2 solutions such as

the FREEDM (HDLC processor), S/UNI IMA (ATM inverse multiplexer)

and AAL1gator (ATM-based CES processor) families.

BENEFITS

•

Complete SONET/SDH front end with T1/E1, DS3/E3

framers/mappers/ multiplexers on a single chip that meets

ATCA/AMC space and power constraints

•

Integrated SBI bus simplifies interconnection to layer 2 processors

•

Meets timing requirements for wireless backhaul, critical for CES-

based PWE3 applications, by enabling independent timing for all

336/252 T1/E1s across the SBI using the V4 byte

•

Extended Serial SONET/SDH Interface (ESSI) can aggregate up to 4x

OC-3/STM-1 on a single 4-wire interface, enabling equipment

protection in ACTA/AMC systems

•

Supports linear 1+1 protection on the same device or to a

companion TEMUX 336 device

•

Enables a scalable architecture from T1/E1 up to OC-12/STM-4

•

Supports T1/E1 mapping directly into SONET/SDH using VT1.5/TU-11

or VT2/TU-12 or multiplexed in DS3s using M13 or G.747

•

Supports advanced test features including programmable pattern

generation and detection for up to 64 byte sequences

•

Fully integrated, monolithic IC ensures reliability
