Single/Dual/Quad/Octal TDM-over-Packet Chip

General Description

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. The high level of
integration available with the DS34S10x devices
minimizes cost, board space, and time to market.
Applications

TDM Circuit Extension Over PSN Leased-Line Services Over PSN TDM Over GPON/EPON TDM Over Cable TDM Over Wireless
Cellular Backhaul Over PSN
Multiservice Over Unified PSN
HDLC-Based Traffic Transport Over PSN
