Product Description

The Loop-IP6702A device allows operators to transport Unframed/Framed 1 E1/FE1 (1 Unframed/Framed T1/FE1) data stream with timing information over PSN (Packet Switched Network) via Pseudowire Protocol – SAToP or CESoPSN . Another IP6702A converts the received packet stream back to original E1/FE1 or T1/FE1 data stream with original timing information. This allows cost-effective migration from existing legacy TDM networks to Packet Switched Network.
