Call Waiting
Call Waiting alerts you to a second incoming call during an active call. This feature is available
as a service through your ISDN line (referred to as “ISDN Call Waiting”) and also from the
DIVAT/A modem itself (referred to as “DIVAT/A Call Waiting”).
The DIVAT/A’s internal Call Waiting uses the second B-channel (if available) to receive a
second incoming call and offer it to you. However, if both B-channels are in use, DIVAT/A Call
Waiting cannot offer you a call, and the second caller will hear a busy signal. ISDN Call
Waiting is handled by your provider and does not need an available B-channel.
Enabling ISDN Call Waiting
ISDN Call Waiting can only be enabled by your ISDN service provider. If you are unsure if your
ISDN line has this feature, check with your provide r.
