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/T1* and Gigabit Ethernet tributary ports of the IP6704A.

Teleprotection is an important technology for mission-critical communications in power grid networks. This technology monitors the health of the power grid, isolates faults and helps prevent serious risks, power disruption, and equpment damage. Teleprotection requires low delay, low jitter and low asymmetry The IP6704 delivers these requirements.

The Loop-IP6704A device supports many interfaces such as E1/FE1, T1/FT1, E&M, X.21, RS232, V.35, EIA530 and C37.94 plus an option DACS (DS0 Cross Connect) feature. IP6704A is an ideal and economical solution for establishing an effective teleprotection system.

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. Another IP6704A converts the received packet stream back to original E1, T1, E&M, X.21 or RS232 data stream with original timing information. This allows cost-effective migration from existing legacy TDM networks to existing PSN.

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