4.2.2 A
NSWERING
You can answer incoming calls at either an extension phone or a phone
device connected to the TAD or PHONE port. You can then conduct the call
normally, for as long as you like.
You can't answer a call that is actively ringing the TAD and PHONE ports
at a device on the FAX or MODEM port, even if that device has a phone
attachment.
4.2.2.A Answering Calls at a Phone on the TAD or PHONE Port (Including
Extensions When Exclusion Is Maintained)
If, after answering a call, you hear silence on the line, the call is probably
coming from a fax that does not produce a CNG signal. Simply transfer the
call to the FAX port by entering the FAX Access Code at your phone (factory-
preset to [1] [1] if it's a touch-tone phone or always just [3] if it's a
rotary/pulse-dialing phone). You can also use this procedure to route a call
when the caller verbally requests the fax machine.
If a caller verbally requests a device connected to the MODEM port, you
can route the call by entering the numbers of the MODEM Access Code at
your phone (factory-preset to [2] [2] if it's a tone phone or always just [4] if
it's a rotary/pulse phone).
See Sections 5.4.1 through 5.4.3 for more information on using and
changing the ASD-4's access codes.
4.2.2.B Answering Calls at an Extension Phone (Exclusion Not Maintained)
When exclusion is not maintained,all extension phones will ring once before
the ASD-4 answers the line. Don't answer the phone on this ring. Instead, wait
until four seconds after the ring stops (so the ASD-4 can try to route the call),
then pick up the receiver. (The ASD-4 will detect the extension and, if it's
been ringing the TAD and PHONE ports, will stop doing so.) If you hear fax
or modem tones, the call should have already been answered by the device on
the FAX or MODEM port; hang up quietly and the transmission shouldn't be
disrupted. If you hear silence on the line, the caller is probably a fax machine
that can't produce CNG tones; you will have to transfer the call to the FAX
port as described below.
During the entire call, the ASD-4 will listen for the touch-tone access codes
that tell it to transfer the call to its TAD and PHONE ports (always just [0]),
to its FAX port (factory-preset to [1] [1]), or its MODEM port (factory-preset
