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 operational E1 equipments without any re-configuration making easy migration to Ethernet technology and thus
accelerating ROI by lowering operational expenses (in months).
