Modules : [ PSPE1S ] [ PSPX21M ] [ PSPLL ]
PSPE1S : Shared E1 over VLAN
This module allows multiples virtual E1 leased line creation
configurations are available :
Point to point (see PSPE1)
Point to multipoint
Multipoint to multipoint
Point to multipoint : E1 interconnection with VLAN line back-up
Main E1 channels (Tetra PBX in this case) are splitted between 4 remote sites.
Multipoint to multipoint : virtual
E1 channels are shared between all 5 sites opening virtual channels and givinf full interoperability between 5 sites.
- The need of physical lines is divided up to 50 %.
- Operationnal costs are tremendously decreased.

PSPE1S equipments are managed by a web browser.
It is possible to manage the entire
link (local and remote equipments).
is made :
- local & remotely trough an "in-band" connection on Ethernet network link
