Dual Trunk E1 Router

Multilink application

Multilink PPP (MLPPP) or Multilink Frame Relay (MLFR) bundles the two E1 ports to pass traffic at twice the speed of a single E1 link. The standard MLPPP per RFC1990 facilitates interoperability with routers from other router vendors.

Apair of Dual E1 Trunk Router can be deployed in a a back-to-back configuration offering a high- speed 4 Mbps point-to-point LAN extension.

Redundancy

With multilink, redundancy is performed at the link layer, if a link is down the traffic is still carried over the active link. If a failed link comes back up again it is automatically added to the bundle, and traffic resumes at twice the speed again.
