nNon-DID calls route to the night destination that you specify for the trunk 
group or for the individual trunk. If you do not specify a night destination, 
the calls route to the DID-LDN night extension.
You can assign a unique extension as the night destination for each incoming 
central-office, foreign-exchange, or 800-Service trunk group. Both the extension 
assigned as a trunk group’s night destination and the DID-LDN night extension 
can be phones or answering groups (such as DDC group, UCD group, or TEG).
Trunk Answer from Any Station
Trunk Answer from Any Station (TAAS) allows phone users to answer all 
incoming calls to the attendant when the attendant is not on duty and when other 
phones have not been designated to answer the calls. The incoming call activates a 
gong, bell, or chime and a phone user dials an access code to answer the call.
Users can activate TAAS if each of the following conditions is met:
nThe attendant has pressed the Night button on the primary console or a user 
(if the switch has no attendant) pressed the Night Service button on the 
designated Night Service phone.
nA night console is not assigned or is not operational.
nNight Station Service is not active.
Trunk Group Night Service
Trunk Group Night Service allows an attendant or a designated Night Service 
phone user to assign one or all trunk groups to Night Service mode. When a user 
activates Night Service, trunk groups that are assigned a Trunk Group Night 
Service termination change to Individual Trunk Night Service mode so that calls 
coming into the trunk group are redirected to the group’s designated Night Service 
extension (NSE). Incoming calls on trunk groups that are not assigned to Trunk 
Group Night Service are queued in the attendant queue. If the call remains 
unanswered during the Night Service Disconnect Timer interval, the incoming 
trunk disconnects.
In addition, a user can assign all the trunk groups to the night service mode at the 
same time. Then all the trunk groups are in the System Night Service mode. Any 
incoming calls made on the trunk groups are redirected to their designated NSE. 
To assign all the trunk groups to System Night Service, the user presses the 
System Night Service button on the principal attendant console or the Night 
Service button on a designated phone. You can assign a Night Service button to 
only one phone.

You can activate Night Service for specific trunk groups (Trunk Group Night 
Service) by pressing the individual Trunk Night Service buttons on the attendant 
console or on a phone. You can assign Trunk Night Service buttons on more than 
one phone.
Considerations
Considerations for Hunt Group Night Service
nBoth Hunt Group Night Service and Trunk Group Night Service can be 
active at the same time. An incoming trunk call is redirected to the trunk 
group’s designated NSE. If this NSE is a hunt group or split that is in Hunt 
Group Night Service mode, the call is redirected to the Hunt Group NSE.
nCalls in progress (such as talking, on hold, or waiting in queue) on the hunt 
group or split are not affected when the hunt group or split is put in Hunt 
Group Night Service mode.
nWhen a hunt-group queue becomes empty, all idle members are placed in a 
busy condition.
nIf Night Service is activated for a hunt group or split and a power failure 
occurs, the hunt group or split automatically returns to the Night Service 
mode.
Considerations for Night Console Service
nThe night console must be identical to and have the same features as the 
primary console. A daytime console can double as the night console.
nNight Console Service calls to the attendant group are still handled by an 
attendant, even though the primary and daytime attendant consoles are out 
of service.
nOnly one night console is allowed in the system. The night console can be 
activated only when the primary and daytime consoles have been 
deactivated.
nIf Night Console Service is active and a power failure occurs, the system 
automatically returns to Night Console Service mode when it is 
powered up.

20
Considerations for Night Station Service
nWhen Night Station Service is active but you have not established Night 
Station extensions, a user can activate Trunk Answer from Any Station 
(TAAS).
nYou can assign a Night-Serv button to either an attendant extension or a 
phone extension. An individual trunk group or hunt group can be put into 
night service by either an attendant extension or a phone extension with the 
necessary button. When a user presses this button to activate Night Station 
Service, all calls to that particular trunk group or hunt group are routed to 
the Night Service extension assigned to that group.
nIf a trunk without disconnect supervision goes to Night Service, the system 
drops the trunk after a period of time to avoid locking up the trunk. The call 
is not routed to the DID-LDN night extension.
Considerations for TAAS
nIf Night Service is active and a power failure occurs, the system, when 
brought back up, automatically returns to Night Service mode.
Considerations for Trunk Group Night Service
nAll incoming calls on Night Service trunk groups go to the trunk group’s 
NSE unless the trunk group member has its own Trunk Group Member 
Night Destination, in which case the calls are redirected to that destination 
instead of the trunk group’s NSE.
nCalls already in progress on a trunk group (such as talking, on hold, or 
waiting in queue), are not affected when the individual Trunk Group Night 
Service or System Night Service is activated.
nTrunk Group Night Service and System Night Service work independently 
of one another.
— When a user activates System Night Service, any trunks that are 
controlled by individual Trunk Group Night Service buttons remain 
in day service. Trunk groups that are not currently assigned to Trunk 
Group Night Service are assigned to System Night Service.
— Trunks with individual Trunk Group Night Service can be removed 
from Night Service even though the rest of the system remains in 
Night Service.
— When a user deactivates System Night Service, any trunks that have 
individual Trunk Group Night Service still active remain in night 
service.
— Trunks with individual Trunk Group Night Service can be placed 
into Night Service even though the rest of the system remains in day 
service.

nIf a trunk is added to a trunk group while that trunk group is in Trunk 
Group Night Service, the trunk is brought up in night service.
nIndividual Trunk Group Night Service does not apply to DID trunk groups.
nIf Night Service is activated for a trunk group, and a power failure occurs, 
the trunk group automatically returns to the Night Service mode.
nIf for some reason, a phone with a trunk-ns button remains out-of-service 
after a system reboot and later comes back in service, the trunk-ns lamp 
shows the trunk status within 10 seconds of coming back in service. For 
example, a phone with a trunk-ns button may be unplugged when the 
system is rebooted. If the phone is plugged back in later, the trunk status is 
shown on the trunk-ns button within 10 seconds.
Interactions
Interactions for Hunt Group Night Service
nACD 
When Hunt Group Night Service is active for a split and the night-service 
destination is a hunt group, the caller hears the first forced announcement 
for the original split. The system then redirects the call to the Night Service 
destination hunt group. When an agent in the Night Service hunt group 
becomes available, the call goes to that agent. If all agents in the hunt group 
are busy, the caller hears the following: forced or delayed first 
announcement, ringback, music-on-hold or silence, and a second 
announcement.
nCall Coverage
Coverage takes precedence over Night Service. When Hunt Group Night 
Service is active, the NSE’s normal coverage criteria and path apply. If the 
coverage path destination is AUDIX, AUDIX answers with the mail of the 
original hunt group. If the NSE is a hunt group or split of any type, the hunt 
group or split’s call coverage criteria and coverage path apply. The 
coverage criteria and path can be different from that assigned to the phones 
that are members of that hunt group or split.
If a coverage point is a hunt group or split in Night Service, the system 
considers the point to be unavailable and does not forward the call to the 
coverage point’s NSE.
nCall Forwarding All Calls
If a hunt group or split is in Hunt Group Night Service mode and the hunt 
group or split’s NSE has Call Forwarding — All Calls active, the system 
forwards night-service calls terminating to that NSE to its designated 
call-forward extension.
If the forwarded-to destination is a hunt group or split in Night Service 
mode, the system terminates the call at the forwarding extension.

Interactions for Night Console Service
nTrunk Group Night Service
Activation of Night Console Service for the attendant consoles also puts 
trunk groups into night service, except those trunk groups for which you 
administered a Trunk Group Night Service button.
Interactions for Night Station Service
nCall Coverage
Calls routed to the night extension via Night Station Service follow the 
coverage path of the night extension under all coverage criteria except 
Send All Calls.
If a night extension has a coverage path in which Cover All Calls is 
administered, all attendant-seeking calls redirect to coverage. Changes to 
the protocol for handling DID-LDN calls (that is, forwarding 
attendant-seeking calls on or off premise from the night extension) do not 
work.
nCall Forwarding All Calls
Calls redirected to the attendant via Call Forwarding All Calls do not route 
to the DID-LDN extension.
nInward Restriction
Inward-restricted phones can be administered for Night Station Service. 
Night Service features override Inward Restriction.
nNight Console Service
Do not provide Night Console Service with this Night Station Service.
nRemote Access
A Remote Access extension can be specified as the Night Station extension 
on an incoming, non-DID, trunk group.
nTenant Partitioning
Each tenant may have a designated night-service station. The system 
directs calls to an attendant group in night service to the night-service 
station of the appropriate tenant (when a night attendant is not available). 
When someone places an attendant group into night service, all trunk 
groups and hunt groups that belong to tenants served by that attendant 
group go into night service. In this case, the system routes incoming calls to 
the night-service destination of the appropriate tenant. 
Each tenant can have its own listed directory number (LDN) night 
destination, trunk answer on any station (TAAS) port, or night attendant.

nTimed Reminder
Timed Reminder calls returning to a console that has been placed in Night 
Service and has an assigned DID-LDN night extension are not redirected to 
the DID-LDN night extension. Rather, they are dropped.
nTrunk Answer from Any Station
TAAS and Night Station Service can both be assigned within the same 
system, but cannot be assigned to the same trunk group.
Interactions for TAAS
nCall Coverage
If Night Station Service is active, calls that are redirected to the attendant 
via Call Coverage can be answered via TAAS.
nCall Forwarding All Calls
If Night Station Service is active, calls that are redirected to the attendant 
via Call Forwarding All Calls can be answered via TAAS.
nInward Restriction
Inward-restricted phones can activate TAAS for incoming trunk calls. 
Night Service features override Inward Restriction.
nNight Console Service
Do not provide a Night Console Service with TAAS.
nNight Station Service
TAAS and Night Station Service can both be assigned within the same 
system, but cannot be assigned to the same trunk group. Activating Night 
Station Service also activates Night Service — Trunk Group for any trunk 
group without an individual trunk-group Night Service button.
nTenant Partitioning
Each tenant can have its own listed directory number (LDN) night 
destination, trunk answer on any station (TAAS) port, or night attendant.

Interactions for Trunk Group Night Service
nCall Forwarding All Calls
If the individual Trunk Group Night Service mode and the trunk group’s 
NSE have Call Forwarding All Calls activated, the night service calls 
terminating to that NSE are forwarded to the designated extension.
nForced First Announcements
An interaction occurs with System Night Service and Forced First 
Announcement. For example, if hunt group A has a forced first 
announcement, assign the incoming CO trunk to terminate at hunt group A. 
Assign the incoming trunk’s night-service destination to be another hunt 
group (hunt group B). Assign a Night Service button to the attendant.
With night service active on the attendant, the incoming CO call routes to 
the night-service destination hunt group B and does not play the Forced 
First Announcement of the incoming destination’s hunt group A.
nListed Directory Number
In System Night Service mode, all incoming LDN calls (except those using 
DID trunks) which have activated night service are redirected to their 
corresponding trunk group’s NSE. Incoming LDN calls using DID trunks 
are directed to the Night Console Service, Night Station Service, or Trunk 
Answer From Any Station, respectively, whichever applies first. Non-LDN 
DID trunk calls terminate at the dialed extension.

1465 Off-Premises Station 
20
Off-Premises Station
Off-Premises Station allows a phone located outside the building where the switch 
is located to be connected to the system. If central office (CO) trunk circuits are 
used, the voice terminal must be analog and must be FCC-registered or, outside 
the US, registered by the appropriate governmental agency. 
Digital communications protocol (DCP) sets can be used as off-premises 
terminals with the addition of the DEFINITY extender. Off-premises stations are 
useful when it is necessary to have a voice terminal located away from the main 
location. The maximum loop distance for off-premises stations is 20,000 feet 
(6093.34 meters) without repeaters. For cabling distance information for the 
various voice terminal types, refer to the DEFINITY ECS System Description.
Detailed description
Off-Premises Station requires cross-connecting capabilities and one port on a 
Analog Line or DS1 Tie Trunk circuit pack for each interface to be provided. Not 
all analog lines can support an off-premises station. For information about analog 
lines, refer to the DEFINITY ECS System Description.
NOTE:
The use of a message waiting indicator lamp on an off-premises station is 
not supported.
Interactions
The Distinctive Ringing feature might function improperly at an off-premises 
station due to the distance. However, the Distinctive Ringing feature can be 
disabled when the Off-Premises Station field is administered. If the Distinctive 
Ringing feature is not used with an off-premises station, the terminal receives 
1-burst ringing for all calls.

1466 PC Interface 
20
PC Interface
The personal computer (PC) Interface consists of the PC/ISDN Platform product 
family. These products are used with DEFINITY ECS to provide users of 
IBM-compatible PCs fully-integrated voice and data workstation capabilities.
Detailed description
Two groups of different configurations are available for PC Interface: group 1 
uses Digital Communications Protocol (DCP) and group 2 uses the ISDN-BRI 
(Basic Rate Interface) protocol.
The group 1 configurations consist of DCP configurations that use a PC/PBX 
Interface card (formerly DCP expansion card) in the PC to link to the switch. 
Group 1 (shown in Figure 57
) uses the following connections:
nThe PC Interface card plugs into an expansion slot on the PC. The card has 
2 standard 8-pin modular jacks (line and phone).
nThe digital phone plugs into the phone jack on the PC Interface card.
nThe line jack on the card provides a digital port connection to DEFINITY 
ECS.
nThe distance between the PC Interface card and the PBX should be no 
more than 1524m for 24-gauge wire or 1219m for 26-gauge wire.
