LAN extension over PDH and SDH networks

CXR proposes simple and powerful solutions of Ethernet Extension between two LAN over a PDH network with n64K, 2Mbps (E1), 8Mbps (4 X E1), 8Mbps (E2), 34Mbps (E3), and 45Mbps (T3/DS3).

This equipment are converting an interface E1, E2 or E3 to bridge Ethernet, they are connecting directly LAN at LAN from two node of PDH network without parameter setting of LAN.

CV200-TTXconnects two part of LAN networks 10/100BaseT by a 2Mbps G703 E1 connection or a n 64kbps G703/G704 FE1. This full duplex solution is transparent to the VLAN.

The solution could be mixed with a DSL extension with CopperLAN and MD20E1 if the configuration need to extend the link far away from PDH switch towards the LAN.

The XM6440 is a solution which implements the aggregation from 2 to 4 E1. This equipment is giving a 7,680 Mbps effective bandwidth between 2 sites. This economic solution will make it possible to set up interconnections of LAN more significant flow than a single E1 access but economic remainder. This solution is full transparent to the VLAN frame.

The CV340FT and CV450FT are bridging solutions of high PDH flow making it possible to connect 2 sites at 34 or 45Mbps in all transparency of protocols LAN IP/IPX, VLAN, MPLS, ISL.

CXR proposes a significant offer of LAN interconnection transported by the SDH ADM STM1 multiplexer HX9100 who can distribute from a loop STM1 155Mbps, up to 12 Ethernet interface of n 2Mbps or n 34Mbps bandwith.
