Intercom Hunt List
The programmer can group up to eight intercom numbers together at an individual telephone to form an
intercom hunt list. The eight numbers can include one personal intercom number and seven group
intercom numbers or eight group intercom numbers.
When someone calls a telephone and it is busy, the call will go to the first idle number in that telephone’s
hunt list and then ring every telephone that has access to that number. An outside line call to a busy
telephone will always go to the hunt list; however, an intercom call will not. To make an intercom call
route to the hunt list, the programmer must include the personal intercom number of that telephone in the
hunt list. The system will not allow you to assign a group intercom number to more than one hunt list at a
time.
When a user has set his or her telephone to forward just prime line and personal intercom calls, those calls
will forward while any other calls to that telephone will go to the hunt list. When a user has set his or her
telephone to forward all calls, then all calls forward and none go to the hunt list.

Intercom Time-out
Should the user select the intercom for use and then perform no dialing or other action, the intercom will
time-out after 10 seconds (at default) and return the telephone to an idle state.
Intercom Call Progress Tones
Internal call progress is marked by the following special tones: Dial tone sounds steady; ring back tone
sounds one second on and three seconds off; tone signaled internal call sounds a two-tone burst every four
seconds at a called station and returns to the caller as ring back; voice signaled internal call sounds a
single tone burst at a called station and returns to the caller as two tone bursts; busy tone sounds one-half
second on and one-half second off at the calling station, and do not disturb tone sounds a fast busy tone
when the called station is in the do not disturb mode. (The system only supplies OPX ports with the
regular busy tone since fast busy tones could interfere with the operation of some accessories that can be
connected to these ports).
Intercom Inter-Digit Dialing
A timer begins timing out after the dialing of each number during intercom number dialing. It also begins
a time-out whenever the station user accesses the intercom number path and does not dial any digits.
When the timer times out, the system returns the station to an idle state.

Key/Hybrid Configuration
Either key system or hybrid configuration is available with the DXP Plus digital communications system.
Whenever the programmer assigns outside lines into line groups and gives individual stations access to
those line groups, the system automatically places itself into the hybrid configuration mode. The installer
does not have to make any physical adjustment to the equipment to achieve the hybrid configuration
mode. The Federal Communications Commission rules and regulations, Part 68, designate a fully
protected hybrid configuration as an MF equipment type category and a key system configuration as a KF
equipment type category. The installer must report the appropriate category registration number to the
telephone company. Operationally, the hybrid configuration enables a PBX feature that may incur a
higher monthly tariff to the telephone company.
