NOTE: This feature currently has some issues - an incoming PSTN call will generate a loud BUZZ if you are on the TBB line.
You can connect an active POTS LINE to the DVG LINE port to enable you to use the POTS line from your single line telephones connected to the DVG ATA - which normally use the Primus TBB service - on port "1".
•Incoming POTS calls will ring on the POTS telephones as well as all devices connected to the DVG "1" port. When you answer with a TBB connected telephone, as you normally would, this now effectively "disconnects" the Primus TBB service from the DVG ATA until you end the POTS call. During this time, any TBB incoming calls are handled as defined in TBB Web Portal Concierge for a DVG Out Of Service.
•Outgoing calls will always be routed through the Primus TBB line unless you use the DVG's ACR Feature.
If your TBB line goes Out Of Service (OOS):
[due to Power Outage, Internet (ISP) connection OOS, Primus TBB servers OOS...]
•Incoming calls on your TBB service will be handled as configured by the account's settings in TBB Web Portal Concierge.
•All outgoing calls will be connected to the LINE port; thus providing an automatic outgoing backup service. Remember that these calls will be handled by your POTS line provider, and you need to take into account any different dialling sequences required, or unexpected Toll charges that may be applicable - based on your particular situation.
