PM8310 TEMUX 336
High Density T1/E1 Framer, VT/TU Mapper & M13 Mux with
Integrated SONET/SDH Framers
Preliminary
Product Brief
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
•
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
equipment protection applications
•
Higher-rate SONET/SDH framers such as the PM5336 ARROW 2488
generation and detection for up to 64 byte sequences
•
Fully integrated, monolithic IC ensures reliability
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.
