Personal Central Office Line (PCOL)
Feature Availability
This feature is available with all Generic 3 releases.
Description
Provides a d edicated trunk for direct access  to or from the public network for 
multiappearance voice terminal users.
Each PCOL can have ap pearance at multiple multiappearance voice terminals.  
Users assigned this feature press the PCOL feature button to answer and place 
calls — dial access is not provided.  The status lamp associated with the PCOL 
button indicates the busy or idle status of the trunk.
An incoming PCOL c all rings all voice terminals assigned the feature (ringing c an 
be either audible or silent, d epending on administration).  The PCOL b utton 
status lamp flashes even if all call appearances at the voice terminal are active.  
If a call appearance is idle, the status lamp associated with that appearance also 
flashes.
CO, FX, and WATS trunks can be assigned to this feature.
PCOLs are not assigned a COR.
Considerations
PCOLs are useful to users such as executives, dispatchers, or buyers with a high 
volume of calls going outside the system, and businesses with specialized 
incoming calls (such as a service department). 
Interactions
The following features interact with the PCOL feature.
nAbbreviated Dialing
Abbreviated Dialing can be used with the PCOL feature. However, the 
accessed lists are associated with the individual voice terminals.
nBrid ged Call Ap pearance
If a user is active on his or her primary extension number on a PCOL call, 
bridged call a p pearances of that  extension number cannot be used to 
bridge onto the call.  The call can only be brid ged onto if another voice 
terminal is a member of the same PCOL group and has a PCOL button.

nCall Coverage
AUDIX cannot be in the coverage path of a PCOL group.
nHold
When a user, active on a PCOL call, puts the c all on Hold, the status lamp 
associated with the PCOL b utton d oes not track the b usy/idle status of the 
PCOL.
nLW C  
LWC messages can be stored for a PCOL group.  The messages are

message is stored, the remote Automatic Message Waiting lamp assigned 
for the PCOL group lights. One remote Automatic Message Waiting lamp  
is allowed per group.
nCDR 
The CDR feature can be activated for PCOL calls, but the CDR record 
does not sp ecifically identify the call as PCOL. A PCOL call can, however, 
be i dentified by the trunk access code used on the call. The call is 
recorded to the extension numb er assigned to the voice terminal where 
the call was originate d or answered.
nSend All Calls
Send All Calls cannot be activated for a PCOL group.
nTemporary Bridged Appearance
When a PCOL is shared (assigned to a group), any group member can 
bridge onto a PCOL call through the Temporary Brid ged Appearance 
feature.  The Privacy — Manual Exclusion feature can be activated on 
such a call if the voice terminal is assigned an Exclusion button.

Personalized Ringing
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows users of certain voice terminals to uniquely identify their own calls.  Each 
user can choose one of a number of possible ringing patterns.
The eight ringing patterns are tone sequences consisting of different 
combinations of three tones.  The eight d ifferent comb inations are listed below.  
The tones are heard in the sequence given for each combination.
n750 Hz, 750 Hz, 750 Hz (normal ringing)
n1060 Hz, 1060 Hz, 1060 Hz
n530 Hz, 530 Hz, 530 Hz
n530 Hz, 1060 Hz, 1060 Hz
n1060 Hz, 1060 Hz, 530 Hz
n1060 Hz, 530 Hz, 530 Hz
n1060 Hz, 530 Hz, 1060 Hz
n530 Hz, 1060 Hz, 530 Hz
Each ringing pattern requires 0.6 second (0.2 second for each tone) in the 5.2 
seconds ringing cycle.  This 0.6 second of personalized ringing occurs at the 
given time during the ringing cycles of the following types of calls (times 
indicated are in seconds):
nInternal voice terminal, internal tie trunk, and remote access calls
0.6 on, 0.6 personalized ringing, 4.0 off
nAttendant extended, attendant originated, and incoming trunk calls, 
including external tie trunk calls
0.2 on, 0.4 off, 0.6 p ersonalized ringing, 4.0 off
nAutomatic Callback, Priority Calling, and Rin g back Queuing Callback calls
0.1 on, 0.1 off, 0.1 on, 0.3 off, 0.6 p ersonalized ringing, 4.0 off
nIntercom Calls (7404D and 7407D voice terminals only)
0.6 personalized ringing, 4.6 off
One of the eight ringing p atterns can be sp ecified for each  eligible voice 
terminal (7303S and 7305S) by the System Manager.  In a d dition, the 7404D, 
7406D, 7407D,  7410D, 7505D, 7506D, 7507D, 8503T,  and 7103A  
						

							Personalized Ringing
Issue  3   March 1996
3-961
programma ble  voice terminal users have the capability of setting their own 
ringing pattern.   The 7404D user can select the desired ringing pattern via the 
given menu options.   The 7406D or 7407D user can select the desired ringing 
pattern by using the Select Ring and PR (Personalized Ringing #) buttons. The 
7103A programmable voice terminal user can select one of four ringing patterns 
via a slide switch on the voice terminal.
Considerations
With Personalized  Ringing, users working closely in the same area can each 
specify a different ringing p attern.  This enables the users to d istinguish their own 
ringing voice terminal from other voice terminals in the same area.
Up to eight different ringing patterns are available.
Interactions
The normal ringing cycles are altered as described in the Description section of 
this feature. With Ad ministrable Distinctive Ringing (G3i-global, G3r, G3V2, and 
later releases) the association between the number of ring bursts and the call 
types is administrable.
Administration
Personalized Ringing is administered for the 7303S and 7305S voice terminals 
on a per-voice terminal basis by the System Manager.   Administration consists 
of assigning one of the eight ringing patterns to each eligible voice terminal.  
Also, a 7404D, 7406D, 7407D,  7410D, 7505D, 7506D, 7507D, 8503T,  or 7103A 
programma ble voice terminal user can specify his or her own ringing p attern. 
The user specified ringing pattern for a 7404D, 7406D, or 7407D,  however, is 
lost in the event of a p ower failure. The user specified ringing pattern for a 7410D 
is lost if the set loses auxiliary power.
Hardware and Software Requirement
No a d ditional hardware or software is required.

Power Failure Transfer
Feature Availability
This feature is available with all Generic 3 releases.
Description
Provides service to and from the local telephone company CO, including WATs, 
during a power failure.
Considerations
Power Failure Transfer provides certain voice terminals with the c a pability to 
access the local CO and to answer c ertain incoming calls d uring a power failure.  
These voice terminals can be used to make or answer important or emergency 
calls.
Each voice terminal can be connected to a separate CO trunk for the Power 
Failure Transfer feature. The Power Failure Transfer feature is available in 
multiples of five.
Local CO trunks (including incoming WATS lines) can be used for Power Failure 
Transfer.
The 500-typ e (rotary dial) or 2500-type (touch-tone or DTMF) voice terminals 
must be used for Power Failure Transfer.  Rotary dialing must b e used if the local 
CO accepts dial p ulses only. When a G3 system is not in the p ower failure mo de, 
power failure transfer terminals (500-type rotary dial) can be used as regular 
extensions.
Interactions
During the Power Failure Transfer mode, no other system features can be 
activated.
If Night Service is activated and a power failure occurs, the system, when 
brought back up, automatically returns to the Night Service mo de.
Administration
None required.

Hardware and Software Requirements
One emergency transfer panel is required for every five or six trunks assigned to 
Power Failure Transfer, de pending on the transfer panel used.  Two emergency 
transfer panels are available:
nZ1A Panel  — Each unit serves up to six power failure transfer terminals. A 
ground-start key is required at each preselected voice terminal when 
ground-start trunks are used.
nPorta-Systems Model 574-5 Panel — Each unit serves up to five failure 
transfer terminals.  The unit provides automatic ground start or loop start.
No a d ditional software is required.

Priority Calling
Feature Availability
This feature is available with all Generic 3 releases.
Description
Provides a special form of call alerting between internal voice terminal users.  
The called voice terminal user receives a distinctive, administrable alerting signal 
(default is a three-burst alerting signal).
An active single-line voice terminal user who receives a Priority Calling call hears 
a distinctive priority Call Waiting tone (the number of bursts is administrable; see 
‘‘Distinctive Ringing’’ for details).
A multi-appearance voice terminal user receives the Priority Calling call on an 
idle call a p pearance. If all call appearances, including the call appearance 
normally reserve d for call origination, are active, the caller receives a busy tone. 
If the call appearance normally reserved for call origination is the only idle call 
appearance, an incoming priority call rings at that call ap p earance.
A user activates priority calling by dialing a Priority Calling access code or 
pressing a Priority button, followed by the d esired extension number. DCS 
priority calling from the attendant station is 
not available.
Whether or not a user can activate Priority  Calling  is  determined by the user’s 
COS.
Considerations
With Priority Calling, a voice terminal user can ring another voice terminal with a 
distinctive signal that tells the called party the incoming call requires immediate 
attention. The called party can then handle the call accordingly. DCS priority 
calling from the attendant station is 
not available.
Call Coverage Consult calls and callback calls from Automatic Callback and 
Ringback Queuing Attendant Intrusion are Priority Calling calls.
Interactions
The following features interact with the Priority Calling feature. 
						

							Priority Calling
Issue  3   March 1996
3-965
nAbbreviated Dialing
If a priority call is to be made to a number in an ab breviated dial list, an 
Abbreviated Dial button must be used. The Ab breviated Dial Feature 
Access Code is not valid after priority calling has been activate d.
nAutomatic Callback and Ringback Queuing
Callback calls do not redirect, d o not forward , and cannot be picked up 
by a Call Pickup group member.
nBrid ged Call Ap pearance
A Bridg e d Call Appearance receives ringing on a priority call the same as 
the called primary extension.
nCall Coverage
Priority Calling c alls d o not redirect to coverage unless the c aller activates 
Go To Cover. If the call redirects, it remains a Priority Call, and the 
covering user receives a distinctive (d efault is three-burst) ringing signal.
nCall Forwarding All Calls
Priority Calling calls (except callback calls) are forwarded, and  the 
forward ed call remains a Priority Calling call.
nCall Waiting Termination
A Priority  Calling call waits on an active single-line voice terminal even if 
the  Call Waiting Termination feature is not assigned to the voice terminal. 
The active single-line voice terminal user receiving the call hears a 
distinctive (default is three-burst) priority Call Waiting tone.
nConsult
A Consult call acts as a priority call and waits at a single-line voice 
terminal, even if the single-line voice terminal does not have Call Waiting 
Indication assigned.
nDial Access to Attendant
A Priority  Calling call cannot be originated to the attendant. However, the 
attendant can originate Priority Calling calls.
nDCS 
On a DCS tandem call to a single-line voice terminal, the called p arty d oes 
not receive priority ringing if the calling party activates Priority Calling after 
he or she has already made the call.  The called party in this situation only 
receives priority ringing if the calling party activates Priority Calling p rior to 
dialing the extension. 
						

							Feature Descriptions
