PSPE1 : E1 over IP/VLAN

    This module allows E1 leased line creation : 

     - trough an Ethernet L3-IP network
     - trough an Ethernet L2-VLAN  network

The choice between the 2 modes is made by a simple mouse click trough the browser.

In IP mode, PSPE1 manage L3 layer conform to IPV4
In VLAN mode, PSPE1 manage L2 layer conform to 802.1Q and 802.1P

Case application : PBX E1 interconnection with VLAN line back-up

Benefits :    

PSPE1 allows to maintain operationnal E1 equipments without any re-configuration making easy migration to Ethernet technology and thus accelating ROI by lowering operationnal expenses.
