Interactions for called-party and calling-party restrictions
nNight Service
Night Service and Night Station — Trunk Answer From Any Station 
override Inward, Manual Terminating Line, and Public Restrictions.
nTie-Trunk Access
Incoming dial-repeating tie-trunk calls can be completed directly to an 
inward-restricted or public-restricted extension but cannot be extended by 
an attendant to an inward-restricted telephone.
nTransfer
Incoming trunk calls cannot be transferred to an inward-restricted 
extension when a 3-way COR check is made.
Incoming trunk calls can be transferred from an unrestricted extension to 
an inward-restricted or public-restricted extension if the 3-way COR check 
on Conference is overridden.
Interactions for fully restricted service restrictions
nCentralized Attendant Service
Since COR information is not passed over Release Link Trunks (RLT), 
fully restricted service allows all CAS calls. Therefore, CAS allows a 
public network call to complete to a fully-restricted station.
nDistributed Communications System
Fully Restricted Service allows all DCS calls because COR information is 
not transparent for DCS. DCS can allow a public network call to be 
completed to a Fully Restricted station.
nPower Failure Transfer
All authorization features are bypassed when the switch is in Emergency 
Transfer Mode. 
nHunt Group
The COR assigned to the Hunt Group is checked on calls redirected by the 
DDC or UCD of the hunt group. Extensions in the hunt group that have 
Fully Restricted Service can receive calls from the public network (via the 
hunt group) if the COR of the Hunt Group does not have Fully Restricted 
Service.
nPersonal Central Office Line
Do not assign fully restricted service to users who have a personal CO line. 
If you do, you will be paying for a CO line that no one can use!

nRemote Access
If a barrier code is entered during connection to remote access, the code’s 
associated COR is used for authorization checks. If remote access does not 
require a barrier code, then the default barrier code’s COR is used. Remote 
Access can require an authorization code instead of or in addition to the 
barrier code. If an authorization code is required, the authorization code’s 
associated COR overrides the barrier code’s COR.
Do not assign fully restricted service to a station with the following features or 
conditions:
nAbbreviated Dialing
nBridged Call Appearance
nAttendant stations
nNight Service stations
nStations that are Call Coverage or Send All Calls points
nStations that are Call Forward destinations
nStations that are Call Pickup points
Interactions for miscellaneous terminal and trunk restrictions
nAAR/ARS
AAR or ARS access to a trunk group overrides miscellaneous trunk 
restrictions.
nAbbreviated Dialing Privileged Group Number List
A telephone user with authorization to access an Abbreviated Dialing 
Privileged Group Number List can place calls to any number on that list. 
COR assignments are not checked.
nPrivileged System Number List
A telephone user with authorization to access a Privileged System Number 
List can place calls to any number on that list. COR assignments are not 
checked.

1319 Conference 
20
Conference
The Conference button allows multiappearance telephone users to make up to six 
party conference calls without attendant assistance. This button also allows 
single-line telephone users to make up to three party conference calls without 
attendant assistance.
Considerations
nA single-line telephone can have up to 6 parties on a conference call, if 
each conferee adds another conferee. For example, one user can add a 
party, who then adds a third party, and so on.
nIf you do not allow trunk-to-trunk connections and a telephone releases 
from a conference call (where all of the other parties were connected to the 
conference via trunks), then all parties are disconnected.
nIf an analog single-line set has Call Wait active and creates a conference 
call, Call Wait is rendered inactive as long as the single-line set is on the 
call. For example, caller A on an analog set talks to caller B, flashes to talk 
to caller C, and flashes to conference B and C. Then, if caller D calls caller 
A, Call Wait is denied.
nUsers of DCP, Hybrid, and wireless phones can conference a call on hold. 
If there is only one call on hold, no active call appearances, and an 
available call appearance for the conference, a user can initiate the 
conference process without taking the call out of hold. When the 
Conference button is pressed, DEFINITY ECS assumes the conference is 
for the call on hold, and the conference feature works as usual.
If there is more than one call on hold, the user must make a call active in 
order to include it in a conference. If the user presses the Conference button 
with two or more calls on hold, DEFINITY ECS will ignore the conference 
attempt since it will not know which call the user wants to conference. If 
there are calls on hold and an active call, pressing the Conference button 
will start the conference process for the active call.
nYou can allow users to abort a conference operation that is in progress by 
hanging up the phone. You set this parameter with the Abort Conference on 
Hang-Up field on the Feature-Related System Parameters
 screen. When a 
user hangs up the phone while trying to conference a call, the existing call 
is placed on hold, and the conference operation is aborted.

1320 Conference 
20
Interactions
nBridged Call Appearance
A bridged call appearance can be used to make conference calls. A bridged 
appearance can bridge onto a conference call only if there were never 6 
parties on the conference. 
nCall Vectoring
A call to a VDN can be included as a party in a conference call only after 
vector processing terminates for that call (for example, after a successful 
route-to command).
nClass of Restriction
If the Restriction Override field is set to 
all, the COR of the party being 
added is always checked against the COR of the party controlling the 
add-on, but the new party’s COR is not checked against any other 
conferee’s CORs.
nTrunk-to-Trunk Transfer
When a multifunction telephone (BRI/Digital/Hybrid) dials sufficient 
digits to route a call, but could route differently if additional digits were 
dialed, the telephone does not recognize the Conference or Transfer 
buttons. The user must delay dialing for 3 seconds or dial # to indicate that 
the call can be routed based on the digits already dialed. The Conference or 
Transfer buttons are then recognized and the switch completes the call.
nVDN in a Coverage Path
Calls in an established conference will not cover to a VDN.
Once a call covers to a VDN, a conference cannot be established until the 
call is delivered to an extension and vector processing ends.

1321 Restriction — Controlled 
20
Restriction — Controlled
Controlled Restrictions allow a telephone user with console permission to activate 
or deactivate specific restrictions.
Detailed description
Use Controlled Restriction to administer the following restrictions:
nOutward — The telephone cannot place calls to the public network.
nTotal — The telephone cannot place or receive calls. (Allowed calls 
include calls to a remote-access extension, terminating-trunk transmission 
tests, and Emergency Access to Attendant calls.)
Direct Inward Dialing (DID) calls are routed to the attendant or a recorded 
announcement. All other calls receive intercept tone.
nTermination — The telephone cannot receive any calls. Incoming calls are 
routed to the attendant, are redirected via Call Coverage, or receive 
intercept treatment.
nStation-to-Station — The telephone cannot place or receive 
station-to-station calls.
nToll — The telephone cannot place toll calls but can place free local calls.
NOTE:
Toll Restriction may be substituted for either the outward or 
station-to-station restrictions. Administer this option on the 
‘‘
Feature-Related System Parameters’’ on page 646.
To activate Controlled Restriction:
1. Dial the group or extension feature access code.
2. Dial the number for the type of restriction desired:
— 1 for outward/toll
— 2 for total
— 3 for termination
— 4 for station-to-station/toll
3. Dial the extension (Attendant Control — Extension) or the Class of 
Restriction (COR) for a group of telephones (Attendant Control — COR).

20
Interactions
nCall Coverage
Controlled Restrictions are not checked for covering users.
nCall Forwarding
Controlled Restrictions for the forwarded-to extension are checked when 
Call Forwarding All Calls is active.
nClass of Restriction
All telephones with the same COR are affected by a group restriction. 
When a call is placed, both individual and group restrictions are checked.
nPriority Call
If a a station user or a Station-to-Station Restricted user activates priority 
calling before they dial another station, they receive intercept tone. They 
receive this tone whether you set Controlled Station to Station Restriction 
on the Feature-Related System Parameters form to 
y or to n.
nUniform Call Distribution
Calls dialed through the UDP are not restricted by Outward Restriction.
Crisis Alert
Crisis Alert notifies designated extensions when an emergency call is made, and 
indicates the origin of the emergency call. This information allows the attendant 
or other user to direct emergency-service response to the caller.
When a user places an emergency call, the system notifies the designated 
extensions with audible and visual alerting. Audible alerting sounds like an 
ambulance siren. Visual alerting consists of flashing of the 
CRSS-ALERT button 
lamp and display of the caller name and extension.
When crisis alerting is active at the attendant console, the console is in 
position-busy mode so that no other incoming calls interfere with the emergency 
call. The console can still originate calls. The attendant must press the 
POSITION-BUSY button to unbusy the console and then the CRSS-ALERT button to 
deactivate audible and visual alerting.

1323 Crisis Alert 
20
Multiple emergency calls
If an emergency call is made while another crisis alert is still active, the call will 
be placed in queue. If you have administered the system so that all users must 
respond, then every user must respond to every call. The calls may not necessarily 
queue in the order in which they were made. 
If you have administered the system so that only one user must respond, the first 
crisis alert remains active at the phone where it was acknowledged. Any 
subsequent calls are queued to the next available station in the order in which they 
were made.
Alerting a digital pager
Crisis Alert to a Digital Pager allows users to receive crisis alert messages on a 
pager. When a crisis alert call is originated in an emergency situation, a message 
of 7 to 22 digits is sent to the pager and displays a crisis alert code, an extension or 
room number, and a main number (if one is entered) so the pagee knows the 
location from which the emergency call originated.  At the same time, an 
emergency call connects over a CAMA trunk.  
To receive a crisis alert message, you need to administer at least one attendant or 
digital set with a 
CRSS-ALRT button. With the Alert Pager field set to y, any station 
with a 
CRSS-ALRT button and a pager receives the correct alert.
NOTE:
The crisis alert call uses 2-4 trunks; 1 trunk for the actual call and 1-3 
trunks to notify the pager(s) depending on the number of 
administered pagers.
Information about the alert can be viewed on the history report printed at the 
journal printer and the emergency log.
Considerations
nOnly one crss-alert button is allowed per attendant console or digital 
station.
nConsoles without a crss-alert button do not receive emergency notification.
nIf a user attempts to make an emergency call, but all trunks are busy, this 
call will not generate an alert. If Outgoing Trunk Queuing is enabled for a 
trunk group, the call will queue, but will not generate an alert.

nCentralized Attendant Service
If CAS is enabled, the alert still goes to the local attendant.
nTenant Partitioning
If tenant partitioning is active, attendants only receive emergency 
notification from callers within their partition. If there is no attendant 
assigned to a partition from which an emergency call originates, the switch 
still sends a record of the call to the journal printer. 
nTerminal Self Administration 
Those users who have the ability to administer their own phones do not 
have the ability to disable a crisis alert button.

1325 Dial Plan 
20
Dial Plan
This is the system’s guide to digit translation. When the system receives dialed 
digits, it must know what to expect next based on the digits received so far. For 
example, if a user dials 4, the system must know how many more digits to expect 
before the call is processed.
All feature access codes, extensions and trunk access codes must be consistent 
with the dial plan.
Detailed description
The dial plan provides information to the switch on what to do with dialed digits. 
Tables define the intended use of a code beginning with a specific first digit or 
pair of digits. These digits tell the system how many digits to collect before 
processing the full digit string.
For example, a digit string beginning with 8 may tell the system to wait for 4 more 
digits because this is the first digit of a 5-digit internal extension. The choices of a 
first digit are 0– 9, *, and #. Permissible codes and the allowable number of digits 
are listed below.
You can also administer a Uniform Dial Plan (UDP) as part of the dial plan to be 
shared among a group of switches. If you establish a UDP, make all extensions the 
same length (4 or 5 digits). So that calls route to the desired switch, a UDP 
requires the following information:
nA PBX code, which represents the first 1 to 5 digits of a 4-digit or 5-digit 
extension and can range from 0 to 9xxxx with a maximum of 50,000 PBX 
codes on G3r or 20,000 PBX codes on G3si/csi.
nAn RNX, which is associated with the PBX code and is used to select an 
AAR pattern for the call. This information is required for each PBX code. 
The 3-digit RNX can be an AAR location code or, for ENP calls, an ENP 
code.
nA PBX ID (1 to 63), which represents a specific switch (optional).
nWhether or not the PBX code is local to this system (optional).
Considerations
nYou cannot assign prefixed extensions longer than five digits (including 
prefix) to intercom lists.
nA trunk access code (TAC) and an extension can share a first digit only if 
the extension is shorter than the TAC.

1326 Dial Plan 
20
nAlthough extensions with the same first digit can have different lengths, 
data-channel extensions must have the maximum number of digits to avoid 
timeout problems for data calls that the switch automatically sets up, for 
example, the Call Detail Recording (CDR) link.
nAn extension and a Feature Access Code (FAC) can share the same first 
digit only if the extension is longer as long as they are not used for 
Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) 
faxes. These extensions work only within the switch; they do not work as 
remote uniform dialing plan (UDP) extensions.
Interactions
All dial-access features and services provided by the system require the dial plan.
nAttendant Display and Telephone (Voice Terminal) Display
Prefixed extensions display without the prefix. The return call button 
causes the prefix to dial, even though it does not display.
nISDN-BRI
When an ISDN-BRI station dials sufficient digits to route a call, but the 
call could route differently if additional digits were dialed, the station does 
not recognize the Conference or Transfer buttons. The user must delay 
dialing for 3 seconds or dial # to indicate that the call can be routed based 
on the digits already dialed. The Conference or Transfer buttons then are 
recognized and the switch completes the operation.
nMF Signaling
Flexible numbering is supported in countries using R2-MFC trunk 
signaling without Group II tones. Different-length extensions can exist as 
long as the extensions have different first digits.
nProperty Management System (PMS)
Remove prefixes before messages containing the extension are sent to the 
PMS. Five-digit extensions do not exchange with PMS until modifications 
are made to the PMS interface. 
nUniform Dial Plan
The following limitations apply to a distributed communications system 
(DCS) environment:
— Extensions that differ in length from the UDP do not distribute to 
other switches.
— If the first two digits of an extension correspond to the floor number, 
floors cannot be serviced by more than one switch.
