Features and technical reference 
1137 Administered Connections 
20
nBusy Verification of Stations and Trunks
This feature does not apply to access endpoints because they are used only 
for data.
nCall Detail Recording
For an AC that uses a trunk when CDR is active, the origination extension 
is the originator of the call.
CDR is not available for access endpoints.
nClass of Restriction
Reserve a COR for AC endpoints and SDDN trunks. This restricts 
endpoints that are not involved in AC from connecting to SDDN trunks or 
endpoints involved in AC.
nClass of Service/Call Forwarding
Assign to an AC endpoint a COS that blocks Call Forwarding activation at 
the endpoint.
nData Call Setup
Do not assign a default dialing destination to a data module when it is used 
in an AC.
nData Hotline
Do not assign a hotline destination to a data module that is used in an AC.
nDigital Multiplexed Interface (DMI)
Use DMI endpoints as the destination in an AC. DMI endpoints do not 
have associated extensions, so do not use them as the originator in an AC.
nFacility Test Calls
The feature does not apply to access endpoints because an access endpoint 
acts as an endpoint rather than as a trunk.
nHunting
Do not use a hunt-group extension as the origination extension of an AC.
nModem Pooling
If you require a modem in an AC, one is inserted automatically. If no 
modem is available, the connection drops.
nNon-Facility Associated Signaling (NFAS) and D-Channel Backup
Auto restoration for an AC that initially is routed over an NFAS facility 
may fail if the only backup route is over the facility on which the backup 
D-channel is administered. The backup D-channel may not come into 
service in time to handle the restoration attempt.

nSet Time Command
When you change the system time via the set time
 command, all scheduled 
AC are examined. If the time change causes an active AC to be outside its 
scheduled period, the AC drops. If the time change causes an inactive AC 
to be within its scheduled period, the switch attempts to establish the AC.
If any AC (scheduled or continuous) is in retry mode and the system time 
changes, the switch attempts to establish the AC.
nSystem Measurements
Access endpoints are not measured. All other trunks in an AC are measured 
as usual.
nTerminal Dialing
Turn off terminal dialing for data modules involved in an AC. This prevents 
display of call-processing messages (INCOMING CALL,...) on the 
terminal.
nTrunk Groups
To invoke auto restoration, route an AC over SDDN trunks. Because a 
successful restoration depends on a SDDN path, keep some SDDN trunks 
idle.
Administrable Language Displays
You can display messages in English, French, Italian, Spanish, or a user-defined 
language on attendant consoles and phones that have 40-character displays.
Detailed description
You can select a language for messages that appear on phones and attendant 
consoles that have 40-character displays. You can choose one of five languages: 
English, French, Italian, Spanish, or “user-defined.” The meanings of the 
messages do not change, only the language.
If your company uses 32-character display phones, you cannot choose a display 
language. These phones, including the hybrid MERLIN 7315H and 7317H 
phones, default to English.

1140 Alternate facility restriction levels 
20
Alternate facility restriction levels
Alternate Facility Restriction Levels (AFRL) allows a second set of facility 
restriction levels within a route pattern or for lines or trunks. Attendants and 
system administrators can activate the alternate FRLs and change users’ access to 
lines and trunks. For example, a company can use AFRL to disable long-distance 
calling at night to prevent unauthorized staff from making long-distance calls.
AFRL alters the route patterns for originating phones, originating trunks, and 
dialed authorization codes. If AFRL is active, Travelling Class Mark (TCM) is 
also set to a new FRL value and the TCM information recorded in the billing data 
(CDR) is the AFRL value, not the original TCM.
!CAUTION:
AFRL impacts Automatic Alternate Routing (AAR) and Automatic Route 
Selection (ARS) call routing because it may change routing preferences. 
Using AFRL on tandem and tie-trunk applications affects entire networks. 
Calls that are part of a cross-country private network and may have to be 
routed further may be blocked.
Detailed description
You can administer an 
ALT-FRL button to any attendant console or any station to 
activate and deactivate the AFRL. Pressing the 
ALT-FRL button may affect the status 
of other buttons.
When AFRL is active, the user may notice a change in calling privileges. Consider 
notifying users of the changes, and prepare your telecommunications department 
to handle inquiries.
Authorization codes
Authorization codes prevent unauthorized access to various facilities. When a user 
dials an authorization code, your system checks the code. If it is not valid, the call 
is intercepted. If the code is valid, the system determines an associated COR and 
FRL. If AFRL is activated, the AFRL level is used.
For example, a user whose FRL is 1 attempts a long-distance call. AFRL is active 
and maps to AFRL 3. The desired trunk has an FRL of 7, and the call is blocked. 
In the example below, an Authorization Code set to1234567 has a COR of 3 with 
an FRL 5, which is still not high enough to access the desired trunk. However, 
AFRL is active and FRL 5 maps to FRL 7. The call is allowed.

1141 Answer detection 
20
Example of authorization codes with AFRLs
Answer detection
For proper call detail recording and accurate billing, you need to know when your 
outgoing calls are answered. Answer detection means the method a switch uses to 
determine whether an outgoing call has been answered.
Brief description
DEFINITY ECS provides 3 ways to determine whether the called party has 
answered a call.
Call classification
A call-classifier circuit pack detects tones and voice-frequency signals on the line 
to determine whether a call has been answered. This method is fairly accurate: 
calls that are answered normally are usually classified correctly. But there are 
exceptions:
nMiscellaneous tones, such as confirmation tones, may be classified as 
answers.
nLoud background noise may activate answer detection, causing a call to be 
classified as answered even if the call is not connected.

1142 Answer detection 
20
nSome calls that are answered may be incorrectly classified as fast busy 
signals.
nCall classifier circuit packs also don’t recognize Special Information Tones 
(SIT) as answers.
Of course, the system generates a call record for any call that is classified as 
answered whether the classification is correct or not. If Call Classification 
incorrectly classifies a call as answered, and then the call is subsequently 
answered, the call duration reported by CDR includes the both time between the 
incorrect classification and the actual answer and the remaining duration of the 
call.
If you want to use call classification, on the System Parameter Customer-Options 
screen verify the Answer Supervision by Call Classifier field is 
y. If not, contact 
your Lucent representative. You also must have a call classifier circuit pack of the 
correct type. To find out what circuit packs you need, refer to DEFINITY ECS 
System Description.
Network answer supervision
The central office sends a signal to the originating switch to indicate that the far 
end has answered. If a call traveled over a private network before reaching the 
central office, the signal is transmitted back over the private network to the 
originating switch. This method is extremely accurate, but it is not available over 
most loop-start trunks (for example, CO, FX and WATS trunks in the US).
Network answer supervision does not override answer supervision by timeout.
Answer supervision by timeout
You set a timer for each trunk group, using the Answer Supervision Timeout field 
on the Trunk Group screen. Or you set a circuit pack timer for the ports on that 
circuit pack, using the Outgoing End of Dial (sec) field on the Trunk Group 
screen. If the caller is off-hook when the timer expires, the system assumes that 
the outgoing call has been answered. This is the least accurate method. Calls that 
are shorter than the timer duration do not generate call records, and calls that ring 
for a long time produce call records whether they are answered. 
If network answer supervision is received, it overrides answer supervision by 
timeout.
Interactions
nCall Detail Recording
Answer Detection provides more accurate call records where tone 
detection is possible and Network Answer Supervision is not received.

1144 Attendant Features 
20
Attendant Call Waiting
Attendant Call Waiting allows an attendant-originated or attendant-extended call 
to a busy single-line telephone to wait at the called telephone so that the attendant 
can handle other calls.
If you want the attendant to be able to send calls to busy single-line phones, set the 
Att. Call Waiting Indication field to Y on the Station
 screen for each single-line 
phone. 
When the single-line phone receives a waiting call, the phone user hears a 
call-waiting signal. You can administer the number of bursts (1, 2, or 3) in the 
call-waiting signal by changing the Attendant Originated Calls field on the 
Feature-Related System Parameters
 screen.
If the attendant activates Attendant Call Waiting, and the Timed Reminder on 
Hold interval or the Return Call Timeout interval expires without the call being 
answered, the call returns to the console. You can modify these intervals on the 
Console Parameters
 screen.
Interactions
nAutomatic Callback
Activating Automatic Callback at the called telephone denies Attendant 
Call Waiting.
nCall Coverage
Attendant Call Waiting calls redirect to coverage if the called phone has 
Data Privacy or Data Restriction activated. If one of these conditions exists, 
and you assign call coverage to a telephone, and the user activates Send All 
Calls or coverage criteria is met, the call redirects to coverage.
— The Coverage Don’t Answer interval specifies how long a call 
remains directed to the called telephone before redirecting to 
coverage. Attendant Call Waiting if applicable on the call, is active 
for the duration of the Don’t Answer interval only. At the end of this 
interval, the call redirects to coverage.
— If the Return Call Timeout (Timed Reminder) interval expires before 
the Don’t Answer interval expires, the call does not go to coverage, 
but returns to an attendant console. If the Don’t Answer interval 
expires first, the call redirects to coverage, but can still return to the 
console if a coverage point does not answer the call before the 
Return Call Timeout.
— If the Station Hunting field is assigned and the called telephone is 
busy, the call redirects to the Hunt To Station Assignment.

nData Privacy, Data Restriction
Activating Data Privacy or Data Restriction at the called telephone denies 
Attendant Call Waiting.
nDDC and UCD
Calls to a DDC or UCD group do not wait. However, they can enter the 
group queue, if provided.
nLoudspeaker Paging Access
Activating Loudspeaker Paging Access at the called telephone denies 
Attendant Call Waiting.
nMusic-on-Hold Access
The calling party hears music if the call is a trunk-transferred call 
administered to receive Music-on-Hold. Otherwise, the calling party hears 
ringing.
nRecorded Telephone Dictation Access
Activating Recorded Telephone Dictation Access at the called telephone 
denies Attendant Call Waiting.
Attendant Control of Trunk Group Access
Attendant Control of Trunk Group Access allows the attendant to control trunk 
groups, and prevents telephone users from directly accessing a controlled trunk 
group. The attendant gains direct access to an outgoing trunk group by pressing 
the button assigned to that trunk group.
Each attendant console has 12 designated Trunk Hundreds Select buttons that can 
be administered for Attendant Control of Trunk Group Access. You can also 
administer each console with up to 12 feature buttons for Trunk Hundreds Select 
buttons, which gives you up to a total of 24 buttons.
Each Trunk Hundreds Select button has busy lamps that light when all the 
members of the associated trunk group are busy. If you administer one of the 
2-lamp feature buttons on a basic console as a Trunk Hundreds Select button, use 
the bottom lamp as the busy lamp. These buttons have 2 additional lamps for 
Attendant Control of Trunk Group Access. The 2 lamps are:
nWarn (warning) lamp
Lights when the administered number of trunks are busy in the associated 
trunk group. You administer the Busy Threshold field on the associated 
Trunk Group
 screen to determine when to light this warning lamp.

nCont (control) lamp
Lights when the attendant activates Attendant Control of Trunk Group 
Access for the associated trunk group. Assign act-tr-grp and deact-tr-g 
buttons on the Attendant Console
 screen to allow the attendant to activate 
and deactivate control of the trunk group access.
Interactions
nAuthorization Codes
Authorization codes do not collect when a trunk group has an incoming 
destination set to the attendant.
nAutomatic Route Selection and Automatic Alternate Routing (ARS/AAR)
Activating Attendant Control of Trunk Group Access removes the 
controlled trunk groups from the ARS and AAR patterns. Deactivating the 
feature reinserts the groups into the patterns. ARS calls do not route to the 
attendant.
nQSIG
QSIG trunks do not support Attendant Control of Trunk Group Access.
nUniform Dial Plan 
Activating Attendant Control of Trunk Group Access removes the 
controlled trunk groups from preferences. Deactivating the feature enables 
the UDP to access the trunk groups.
Attendant Direct Extension Selection
Attendant Direct Extension Selection (DXS) with busy lamp field allows the 
attendant to track extension status (idle or busy) and to place or extend calls to 
extension numbers without having to dial the extension. 
Standard DXS Tracking
The basic selector console has 8 Hundreds Select buttons and 100 DXS buttons. 
The enhanced selector console has 20 Hundreds Select buttons and 100 DXS 
buttons. You can assign 12 additional Hundreds Select buttons to feature buttons 
on the attendant console.
However, as you assign these feature buttons, note that the total number of 
Hundreds Select buttons per attendant (including both attendant-console feature 
buttons and selector-console buttons) cannot exceed 20.
