							INTRUSION (BARGE-IN)
Description
Intrusion permits an extension user to break into another extension user’s established call.  This sets up a three-
way conversation between the intruding extension and the two parties on the initial call.  With Intrusion, an ex-
tension user can get a message through to a busy co-worker right away.
In addition to Intrusion, the following features also allow three-party calls:
•Conference
•Meet-Me-Conference
•Privacy Release Groups
•Tandem Calls
CAUTION:
Unauthorized intrusion on calls using this feature may be interpreted as an invasion of privacy.
Conditions 
The system supports eight simultaneous Conferences (three-party conversations).  Under certain conditions, this
may prevent an Intrusion.
Default Configuration
Intrusion disabled in all Classes of Service.

							LAST NUMBER REDIAL
Description
Last Number Redial allows an extension user to quickly redial the last number dialed.  For example, a keyset
user may recall a busy or unanswered number without manually dialing the digits.
Last Number Redial saves in system memory the last 24 digits a user dials.  The number can be any combina-
tion of digits 0-9, # or *.  The system remembers the digits regardless of whether the call was answered, unan-
swered or busy.  Normally, the system uses the same trunk (or rotary) for Last Number Redial as the user
selected for the initial call.  The keyset user can, however, select a different trunk before implementing Last
Number Redial.
Conditions 
(A.) A power failure or system reset erases all stored Last Number Redial numbers.
(B.) If a user waits more than six seconds between digits while dialing, Last Number Redial remembers only
the digits after the pause.
(C.) When a telephone number is manually dialed the DTMF on tones = 250 mS.  When the system redials
the DTMF on tones = 135 mS.
Default Configuration
Last Number Redial always enabled.

Other Programming

Allow or prevent the system from outdialing a # if dialed as part of the initial call. [Y=deny #, N=allow #]

Automatic Route Selection
Unless the user preselects a trunk, the system enforces ARS for Last Number Redial calls.
Central Office Calls, Placing
This feature gives extension users convenient options to dialing manually.
Line (Trunk) Queuing
If an extension user implements this feature and hears busy tone, they can queue for a trunk.  The call di-
als automatically when the user answers the Callback ring.
Save
Last Number Redial simplifies recalling a busy or unanswered call.
Speed Dial
Last Number Redial can redial Speed Dial numbers.
Toll Restriction
The system applies Toll Restriction to all Last Number Redial calls.  If you don’t dial enough digits (as
determined by your Toll Restriction programming), Last Number Redial will not retain your last call.
Walking Class of Service
If an extension user implements Walking Class of Service to place a call, Last Number Redial can redial
it.

							LINE (TRUNK) QUEUING
Description
Trunk Queuing (Callback) permits an extension user to queue (wait in line) for a busy trunk or trunk group to be-
come free.  The system recalls the queued extension as soon as a trunk is available. The user does not have to
manually retry their call later. Trunk Queuing lets the caller know when the call can go through.
Any number of extensions may simultaneously queue for the same trunk or trunk group.  When a trunk becomes
free, the system recalls the extensions in the order that the queues were left. If the extension does not answer the
Callback ring, the system:
•Rings the next extension in queue
•Removes an unanswered extension from the queue and cancels its Callback
OR
Skips a busy extension and retries it later on
Selected extensions can have Callback priority, set in the extension’s Class of Service.  When multiple exten-
sions queue for a trunk, those with priority receive Callback first.
Conditions 
A power failure or system reset cancels all Trunk Queuing requests.
Default Configuration
Callback enabled.

							LINE (TRUNK) ROTARIES (HYBRID ONLY)
Description
A trunk rotary is a programmed group of trunks used for outgoing calls.  The system allows up to nine trunk ro-
taries, numbered 90-98.  The rotaries should consist of trunks of the same type (e.g., WATS band 5 or WATS
band 3).  Users can select trunk rotaries when placing outside calls.  To select a rotary, the user dials the trunk
(rotary) group code.  The system then selects the first available trunk from the group.
The system administrator can use rotaries to help control the cost of outside calls.  By restricting access to cer-
tain rotaries, the administrator can force users to select lower cost lines when placing calls.
If your system has trunk rotaries, the FCC classifies it as a hybrid.  You must use FCC registration number
BJ286G-10094-MF-E. If your system doesn’t use trunk rotaries, the FCC classifies it as a key system.  Use FCC
registration number BJ286G-16856-KF-E.
Conditions 
None
Default Configuration
No trunk rotaries configured.
Programming
Required Programming
➣E- Extensions, E8- Line Access Options, Access To Groups 90-95
Allow/deny access to each of the first 6 trunk groups (90-95). You cannot program this option for trunk
groups 96-98. [Y=allow, N=deny]
➣E- Trunks, E4- Next Trunk in Outbound Rotary (Hybrid Only)
This determines the selection sequence for trunks within the rotary.  Make sure the last trunk in the rotary
is terminated to that trunk’s operator (e.g., 300).
➣E- Trunks, EA- Trunk Group Assign. (First Trunk in Group), Hybrid
Group trunks together by assigning each one the same First Trunk in Group number.
➣QF- Line Grp Access (First Trunk in Group), Hybrid Only
Correlate the first trunk in a trunk rotary (e.g., 801) to one of nine trunk rotary numbers (90-98).  The sys-
tem requires this correlation when setting up trunk rotaries.  Use the trunk access code (e.g., 801) that
corresponds to the EA- First Trunk in Group entry.
Other Programming
➣E- Extensions, ED- Trunk Control, Access Control / ED- Trunk Control, Call-Out Control
To use a rotary, an extension must have access and call-out for the trunks in the rotary.

Call Forwarding
An extension user should not forward calls off-premise using a trunk group (codes 9 or 90-98).
Central Office Calls, Placing
The system does not search a rotary for an idle trunk when the user dials a trunk access code (e.g., 801).
Direct Inward Line (DIL)
A DIL can be a member of a trunk rotary (for placing calls). While busy on an outgoing call, the DIL is
unavailable for incoming calls.
Line (Trunk) Queuing
The user can queue for an available trunk if all trunks in the group are busy.
Loop Keys
Loop keys use the programmed trunk rotaries.
PBX/Centrex Compatibility
Place PBX lines in their own trunk rotaries.
Speed Dial
Speed Dial bins can use trunk groups instead of specific trunks.
System Reports, Diagnostics and Maintenance Utilities
The HC- System Queues report displays the trunk rotary queues. The HE/HF- Traffic Management Sum-
mary option summarizes the trunk group call activity.

							LOOP KEYS
Description
Loop keys are programmable keys that simplify the way extension users place and answer outside calls.  There
are two types of loop keys: fixed loop keys and switched loop keys.  Fixed loop keys give the user single key ac-
cess to a specific trunk group.  Switched loop keys give the user simplified access to any trunk group.  Switched
loop keys are primarily used by extensions that answer a large amount of calls.
Loop keys are also important for answering calls.  An incoming call not assigned to a key rings the first avail-
able loop key. This ensures a key appearance for any call ringing an extension. For this reason, each extension
should have at least one loop key.  On key systems, loop keys are for incoming calls only. Only switched loop
keys are available.
Conditions 
An incoming call without an assigned key rings the first available loop key.  The system searches the keys in the
following order looking for a loop key: 1-15, 21-24 then 16-20.
Default Configuration
No loop keys programmed.
