Loop Telecom Multiservice Access TDMoE IP6704A / Loop-IP6704A-S-PPM-E75-E120-X21-RS232-ISD48-ISD48-G

SKU: 4261 Category:



The Loop-IP6704A device allows operators to transport E1 ,T1*, E&M, X.21, or RS232 data stream with timing information over PSN (Packet Switched Network) via Pseudowire Protocol SAToP/CESoPSN/MEF8*.


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 E1/FE1, T1/FT1, E&M, X.21, RS232, QFXSA or QFXO data stream with timing information over PSN (Packet Switched Network) via Pseudowire Protocol – SAToP/CESoPSN/MEF8*. Another IP6704A converts the received packet stream back to original E1/FE1, T1/FT1, E&M, X.21, RS232, QFXSA or QFXO data stream with original timing information. This allows cost-effective migration from existing legacy TDM networks to existing PSN.


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