DS34T101/DS34T102/DS34T104/DS34T108
Single/Dual/Quad/Octal TDM-Over-Packet Chip
General Description
Features
The IETF PWE3 SAToP/CESoPSN/TDMoIP/HDLC
draft-compliant DS34T108 allows up to eight T1/E1
links or frame-based serial HDLC links to be
transported transparently through a switched IP or
MPLS packet network. Jitter and wander of
recovered clocks conform to G.823/G.824, G.8261,
and TDM specifications. This eliminates the need for
remote timing sources in cabinets and pedestals.

Full-Featured T1/E1/J1 LIU/Framer/TDM-Over-
Packet
Supports Adaptive Clock Recovery, Common
Clock (Using RTP), External Clock, and
Loopback Timing Modes

Selectable 32-Bit or 16-Bit Processor Bus
Clock Rate Adapter for T1/E1 Master Clock
10/100 Ethernet MAC That Supports
MII/RMII/SSMII
The Ethernet side of the DS34T108 provides high
QoS capabilities to its MII/RMII/SSMII port, while the
WAN side supports full-featured T1/E1 framers and
LIUs. This takes the solution all the way through
analog, while preserving options to make use of TDM
streams at key intermediate points. The high level of
integration that the DS34T108 brings minimizes cost,
board space, and time to market.
