Product Description

The Loop-IP6704A TDMoEthernet is an ideal solution for service providers to build their network and achieve a fast return on investment. Currently providers need to transport both TDM and Packet traffic. These can be achieved using the E1/FE1,T1/FT1 and Gigabit Ethernet tributary ports of the IP6704A.

The Loop-IP6704A device allows operators to transport E 1 /FE1 T1 /FT1 , E&M, X.21, RS232 V.35 ,EIA530 ,QFXSA or QFXO , G.703, C37.94 data stream with timing in formation over PSN (Packet Switched Network)via Pseudowire Protocol SAToP/CESoPSN/MEF8. Another IP6704 A converts the received packet stream back to original E1 /FE1 , T1 /FT1 , E&M, X.21, RS232 V.35, EIA530, QFXSA or QFXO , G.703, C37.94 data stream with o riginal timing information. This allows cost effective migration from existing legacy TDM networksto existing PSN.

For transport of TDM signals, the Jitter and Wander adheres to G.823/G.824 Traffic Interface.
