DS34T101, DS34T102, DS34T104, DS34T108
Single/Dual/Quad/Octal TDM-over-Packet Chip
General Description
Features
♦
♦
♦
Full-Featured IC Includes E1/T1 LIUs and
Framers, TDMoP Engine, and 10/100 MAC
These IETF PWE3 SAToP/CESoPSN/TDMoIP/HDLC
compliant devices allow up to eight E1, T1 or serial
streams or one high-speed E3, T3, STS-1 or serial
stream to be transported transparently over IP, MPLS
or Ethernet networks. Jitter and wander of recovered
clocks conform to G.823/G.824, G.8261, and TDM
specifications. TDM data is transported in up to 64
individually configurable bundles. All standards-
based TDM-over-packet mapping methods are
supported except AAL2. Frame-based serial HDLC
data flows are also supported. With built-in full-
featured E1/T1 framers and LIUs. These ICs
encapsulate the TDM-over-packet solution from
analog E1/T1 signal to Ethernet MII while preserving
options to make use of TDM streams at key
intermediate points. The high level of integration
available with the DS34T10x devices minimizes cost,
board space, and time to market.
