PSPX21M : X21 over IP/VLAN

 

    This module allows X21  leased line creation :

trough an Ethernet L3-IP networks.
trough an Ethernet L2-VLAN  networks

In IP mode, PSPX21 manage L3 layer conform to IPV4
In VLAN mode, PSPX21 manage L2 layer conform to 802.1Q and 802.1P

 

Case application : X21 interconnection with VLAN line back-up

Benefits :    

PSPX21 allows to maintain operationnal X21 equipments without any re-configuration making easy migration to Ethernet technology deploy inside company or operators new services.
