That one jack on the control unit be dedicated to the ASA features
At startup, jack number 18 is automatically designated as the ASA jack.
An Auto Access cord that you plug into this jack is connected to the memory
module which houses the VSP. If you want to change this jack assignment,
follow the simple administration procedure discussed under
"Automatic System Access" earlier in this section.
Its own incoming line group.
The feature's operation includes only calls coming in on lines assigned to the
DXD incoming line group. Calls coming in on lines not in the DXD
incoming line group arc not answered by the DXD feature. At startup, no
lines are assigned to the DXD incoming line group. There's a simple
procedure (discussed under "Administration") for changing the makeup of
the DXD incoming line group.
CF and DXD are mutually exclusive modes: the system cannot be in both modes
at the same time.
Direct Extension Dialing cannot be used with the MERLIN Attendant.
There can be more than one CF/DXD button in the system, but there can be only
one CF/DXD button on a voice terminal. If two or more users have a CF/DXD
button programmed on their voice terminals, each of them can turn the features
on and off. For example, if one of these users activates the Direct Extension
Dialing feature, the green light goes on next to the CF/DXD buttons on all the
voice terminals that have a button for the feature. When the person deactivates
the feature by touching the CF/DXD button, the light goes off next to the button
at all the voice terminals that have programmed the CF/DXD features.
You should consider having a Transfer Return Interval if you plan to use DXD.
(See "Transfer Return lnterval.") Depending on the incoming call traffic, you
may also want to designate an alternate attendant position to handle all returning
ASA calls, (See "Alternate Attendant.")
When a caller responds to the voice prompt by entering an intercom number,
the control unit uses the system's transfer feature to transfer the call to the voice
terminal with that intercom number. If the call goes unanswered at the
destination voice terminal and there is an administered Transfer Return Interval,
the call is transferred to the administrator/attendant or the alternate attendant
console when the interval expires.
If the system is administered for no return of transferred calls, the call continues
to ring at the destination voice terminal until the caller hangs up.
If a compatible audio-source is available, Music-On-Hold is recommended for
DXD, so that the caller can hear music while waiting. See "Music-On-Hold"
under "Accessory Equipment" later in this section.
If the system is in both DXD and Remote Line Access modes and the lines
overlap, DXD takes precedence.
