Digital E1 Backup Configuration - Davolink DV-332 User Manual

DV-332 Analog/Digital User Guide

8.1.2 Digital E1 backup configuration

1) 1+1 PSTN backup
If you use DV-332 digital E1 2 ports as 1+1 (PSTN) backup, port 0 will be connected to the internal
PBX and port 1 will be connected to PSTN E1 lines. If users cannot make VoIP calls because of errors
(such as "network problems" and "server not connected"), then it can be rerouted to backup PSTN
lines to make calls. The only difference between analog and digital PSTN backup configuration is an
interface that each uses. Digital PSTN backup uses E1 interfaces.

2) PBX backup
If you use DV-332 digital E1 1 or 2 ports to be connected to the PBX, you can send/receive VoIP calls
via DV-332 E1 port(s) in a normal service time. If errors (such as "Etnernet WAN Link down" or
"Server not connected") occur, you can block DV-332 E1 port physically or manually. In order to do
so, all you have to do is configuring following option (and you don't need to set up in
/CONFIG/REROUTE).
