Hayes Microcomputer Products DIVA T/A ISDN manual Data Over Voice

The following parameters can be configured:

Parameter Description

Enable DOV

(Data Over Voice)

(North America only)

Enable DBA

(Dynamic Bandwidth Allocation)

Specifies Data Over Voice Bearer Capability as the outgoing call type.

If voice calls are less expensive than data calls in your tariff area, you can select this option. DOV calls are data calls made over a BRI line using Voice Bearer Capability.

For DOV to work, the remote device to which you are connecting must support incoming DOV calls.

Note: Only applicable if your ISDN connection protocol is Multilink PPP.

Note: Only available on models equipped with analog device ports.

When activated this function lets you initiate or receive telephone calls on your regular (non-ISDN) telephone without interrupting your current connection. It releases one B-channel, as required for analog device calls, without interrupting the data link. After the phone call is completed and you hang up the B-channel is automatically brought back up for your current connection.

Default: DBA disabled.
