We currently have an SDSL which we would like to use as a failover once we get our T-1 line. The modem which is currently being used for this sdsl is a NETOPIA.
There is another modem which is a dedicated PRI T1 for voice but is currently not providing data. It it connected to a modem with ports which read WAN-T1, DSX-1, DBU. The WAN-T1 and DSX-1 are connected but the DBU is not.
How do I implement a failover? I've never done it.
