telephone company should provide the appropriate
commands.
The 3C882 ISDN modem will announce a forwarded call by
producing a short ring on the telephone that is routed to the
forwarded number.
ISDN Call Waiting
ISDN Call Waiting allows you to place a voice call on hold
while you answer an incoming voice call.
By default, ISDN Call Waiting is disabled on analog port 2
(S76=1). To avoid potential call interruptions when sending or
receiving a fax transmission, you should therefore install your
fax machine on analog port 2.
Table 6-1 How to Use Call Waiting
How Do I Do This
Place the first call on hold and
answer the second?
When you hear the call waiting indicator, press and
immediately release the switch hook button.
Place the second call on hold
and then switch back to the first
call?
Press and release the flash hook. The second call is
then put on hold.
End the first call and then
answer the second call?
Hang up the telephone, wait for the telephone to ring,
and then answer the call.
What if the call on hold is
dropped?
If the call on hold hangs up at the far end, you will
receive no notice. If you press and release the switch
hook button, you will get a dial tone, indicating that
the call on hold was dropped. Press and release the
switch hook button again to return to the previously
active caller.
What if the active caller hangs
up?
If the active caller hangs up, the call on hold remains
on hold until you retrieve it by pressing and
immediately releasing the switch hook button. If you
hang up while a call is on hold, the telephone will ring
to indicate that there is a call on hold. If you do not
retrieve the call within 6 seconds, the call is dropped.
