The CIP-2E1T1 carry TDM E1 or T1 or fractional d’E1 fractional E1/T1 of n TS encapsulated via Ethernet or IP pipe. A bundle of one full E1/T1 or n TS is carried in a « Pseudowire Emulation End to End » (PW3E) over a Packet Switched Network (PSN) means IP or Ethernet or MPLS network.

This transport emulate the full E1/T1 service and both end equipments like PBX or PDH muxes get the E links as direct connection like strait cable or E1/T1 over fiber or E1/T1 over DSL connection.

Telco use CIP-2E1T1 to carry E1/T1 to distribute voice and data over Ethernet cloud to the subscribers. With the OCXO option the PseudoWire equipment (PW) is enable to regenerate the synchronization clock in the customer premises.

The CIP-2E1T1 carry the E1/FE1 or T1/FT1 in point to point or point to multi-points. One bundle can be set per full E1 or T1 (G703) or fractional FE1 G704 or FT1. In case of channelized E1/T1, when the group of TS are transported to multi-points, we set a bundle per direction and group of TS. The CIP-2E1T1 is grooming the n64Kbps circuit from several distant sites using CIP-2E1T1 or other PW RFC compliant equipments.

A CIP-2E1T1 box owns 2 E1/T1 TDM interfaces and can support up to 64 bundles or directions. Each bundle can be routed to 64 different distant sites. Each bundle can use any of CESoPSN, SAToP or AAL1 (TDMoverIP) protocol. Two bundles will be used as protection in addition to the WAN protection.
