2.2 The ASD-4's Ports

There are five modular ports and a power input port on the rear panel of the
ASD-4, as shown in Figure 2-1:
LINE-IN
You connect telephone equipment to the modular ports on the ASD-4 as
follows:
Plug the incoming line from the telephone company into the LINE-IN port.
Plug your Telephone Answering Device (TAD, answering machine or
integrated phone/answering machine) into the TAD port. The ASD-4 will
route a call to the TAD and PHONE ports if it answers the call and does not
detect routing tones. (The TAD and PHONE ports are internally connected
and ring simultaneously.)
Connect a single phone line to the PHONE port, regardless of whether
you're using one phone, multiple phones, or a KSU/PBX system. The ASD-4
will route a call to the TAD and PHONE ports if it answers the call and does
not detect routing tones.
Plug your fax machine into the FAX port. For the ASD-4 to automatically
transfer any fax call with a CalliNG (CNG) tone to your fax machine, the fax
machine must be plugged into this port. You can connect a modem or
fax/modem to this port in lieu of a fax machine.
You can plug any type of telephone device to the MODEM port. If you are
connecting a modem to the ASD-4, we recommend that you plug the modem
into this port.
