Private Networking Features 
111 QSIG 
DCS Over ISDN-PRI D-channel
Enhances DCS by allowing access to the public network for DCS connections between 
DCS switch nodes. With this feature (also known as DCS+), DCS features are no longer 
restricted to private facilities. The ISDN-PRI B-channel is used for voice communications, 
and the ISDN-PRI D-channel is used to transport DCS control information.
QSIG
QSIG provides compliance to the International Organization for Standardization (ISO) 
ISDN-PRI private-networking specifications. QSIG is defined by ISO as the worldwide 
standard for private networks. QSIG features are supported on BRI trunks.
QSIG is the generic name for a family of signaling protocols. The Q-reference point or 
interface is the logical point where signaling is passed between 2 peer entities in a private 
network. QSIG signaling can provide feature transparency in a single-vendor or 
multi-vendor environment.
QSIG provides call-related Supplementary Services. These are services that go beyond 
voice or data connectivity and number transport and display. Examples of Supplementary 
Services include Name Identification, Call Forwarding (Diversion), and Call Transfer.
Call Completion
Call Completion utilizes the QSIG Platform enhancement Call Independent Signaling 
Connections and is functionally equivalent to the Distributed Communications System 
(DCS) feature: AutoCallback. 
Call Independent Signaling Connections 
(CISC)
Call Independent Signaling Connections (CISC) are used to pass QSIG Supplementary 
Service information that is independent of an active call between two QSIG compliant 
nodes. Implementation is based on the ISO standard for CISC.  It is possible to determine 
the status of a QSIG TSC by using the status Signaling group command on the SAT.

Overview  555-233-002  Issue 1

Manufacturer-Specific Information (MSI)
QSIG handles non-standardized information that is specific to a particular PBX or 
network. This information is known as Manufacturer Specific Information (MSI). A 
manufacturer can define manufacturer-specific supplementary services operations after it 
has:
nApplied to a sponsoring and issuing organization (ECMA or European Computer 
Manufacturers Association in this case)
nBeen assigned an organization identifier. This organization identifier is used as the 
root of the manufacturer-specific service-operation value. 
All MSI operation values should be unique to that manufacturer. 
Manufacturer-specific supplementary services can be created using specific operations 
encoded with the manufacturer’s identifier. DEFINITY ECS supports non-QSIG 
applications that transport information across QSIG networks in MSI. Applications now 
have the same functionality over QSIG networks that they have over non-QSIG networks. 
Applications that use MSI include Centralized Attendant Service, Transfer to Audix, Best 
Service Routing, and QSIG VALU.
Path Replacement
With this feature, a call’s connections between switches in a private network can be 
replaced with new connections while the call is active. This feature is invoked when a call 
is transferred and improvements may be made in costs. For example, after a call is 
transferred, the two parties on the transferred call can be connected directly and the 
unnecessary trunks are dropped off the call. The routing administered at the endpoints 
may allow for a more cost-effective connection.
Call Forwarding (Diversion)
QSIG Call Forwarding (Diversion) is based on the DEFINITY ECS Call Forwarding 
feature. It extends the feature transparency aspects of Call Forwarding over a QSIG 
trunk:
nIf QSIG Call Forwarding is activated, all calls are diverted immediately.
nIf QSIG Call Forwarding with Busy/Don’t Answer is activated and a station is busy, 
a call is diverted immediately.

Private Networking Features 
113 QSIG 
nIf QSIG Call Forwarding with Busy/Don’t Answer is activated and a station is idle 
but the call is not answered, a call is diverted after a specified number of rings.
These features are activated either by dialing a Feature Access Code (FAC) or by 
pressing a button. See Call Forwarding for detailed descriptions of how to use these 
features.
Call Transfer
QSIG Call Transfer differs from the standard DEFINITY ECS Transfer feature in that 
additional call information is available for the connected parties after the transfer 
completes. However, the information is only sent for QSIG trunks. If one call is local to the 
transferring switch, that user receives the name of the party at the far end.
Name and Number Identification
Allows a switch to send and receive the calling number, calling name, connected number, 
and connected name. Additional parameters that control the display of the connected 
name and number are administered on the Feature-Related System-Parameters form. 
QSIG Name and Number Identification displays up to 15 characters for the calling and 
connected name and up to 15 digits for the calling and connected number across 
ISDN-PRI interfaces.
Called NAME ID
The QSIG Called Name feature presents the called party’s name on the calling party’s 
display while the call is ringing. It then reverts to “connected name” when answered.
Call Offer
This feature, on request from the calling-user (or on that user’s behalf), enables a call to:
nBe offered to a busy called-user 
nWait for a busy called-user to accept the call when the necessary resources have 
become available

QSIG Centralized Attendant Service (CAS)
Provides you with the capability to have all your Attendants in one location, serving users 
in multiple locations. QSIG CAS does not utilize separate Release Link Trunks (RLT). 
This feature will not restrict calls from going out over non-QSIG trunks; however, the full 
functionality of the QSIG CAS will not be available. 
RLT Emulation via a PRI
ISDN QSIG trunks will route calls from the branch PBX to the main PBX. You no longer 
have to specify a dedicated RLT network. The QSIG Path replacement takes care of the 
trunk optimization. You have the flexibility to route calls to the main PBX.
Attendant Display of Class of Restriction (COR)
While on a call, the Attendant can press a COR display button to see the Class of 
Restriction of the user.  The Attendant will not block the transfer of the restricted line to 
the user.  This feature is used for informational purposes only.
Attendant Return Call
If a call that is transferred by the Attendant goes unanswered for a specified period of 
time, the call is returned to the Attendant. Preferably the call will transfer back to the 
Attendant who transferred the call.
Priority Queue
QSIG MSI will pass more information to the main PBX.  This information enables calls 
coming in from a QSIG CAS branch to be placed in the appropriate place in the queue, as 
if the call originated on the main PBX.
QSIG VALU
Distinctive Alerting
Provides distinctive ringing, internal and external, to the remote called party when the call 
is routed over the QSIG network. 
Call Coverage
Provides similar call coverage as DCS Call Coverage and Call Coverage Remote Off Net 
or C-CRON. Call will come back if covered over QSIG.  The functionality will only be 
complete when all the switches are DEFINITY ECS and using QSIG VALU.  The 
Covered-to party can still receive Distinct Alerting.

Call Coverage and CAS
When a trunk has both CAS and VALU Call Coverage activated, the coverage display 
information is provided on calls that cover from a branch PBX to the main PBX. Path 
replacement will be attempted after coverage.
QSIG Voice Mail Capabilities
QSIG voice mail allows users on a remote switch to cover to a voice mail system on 
another switch, provided the voice mail system uses a QSIG interface. Users receive a 
message-waiting indication (message lamp or stutter dial tone) and have access to most 
functions of the voice mail system. When the DEFINITY ECS and a voice mail system are 
connected via QSIG, users can transfer directly into a mailbox on the voice mail system. 
Transfer to voice mail is activated by a feature access code and requires QSIG MSI

DEFINITY AUDIX
While many voice messaging systems require separate equipment and connections, the 
DEFINITY AUDIX System easily installs directly into your DEFINITY ECS cabinet to 
support advanced voice messaging capabilities without the need for an adjunct 
processor.
Each DEFINITY AUDIX system supports up to 2000 mailboxes and stores up to 100 
hours of recorded messages. It can be configured with 2 to16 ports (in two-port 
increments).
Whenever you call the DEFINITY AUDIX system, you interact with it by entering 
commands through your telephone’s touch-tone keypad. You simply specify the desired 
activity, and follow the voice prompts for the desired task.
Special voice-processing features include Voice Mail, Call Answering, Outcalling, 
Multi-Level Automated Attendant, and Bulletin Board. The following is a summary of 
DEFINITY AUDIX capabilities:
nShared Extensions provide personal mailboxes for each person sharing a phone
nMultiple Personal Greetings allows you to prepare a pool of up to nine personal 
greetings to save time and provide more personal customer service. Separate 
messages can indicate you are on the phone, away from the desk, on vacation, etc. 
You can assign different messages to internal, external, or after-hours calls
nPriority Messaging places important messages ahead of others.  Internal and 
External callers can mark the message as priority.
nOutcalling automatically dials a prearranged phone number or pager when you 
have messages in your voice mailbox
nPriority Outcalling automatically dials a prearranged phone number or pager when 
you have 
priority messages in your voice mailbox

INTUITY AUDIX
INTUITY Messaging Solutions essentially offers the same user features as the DEFINITY 
AUDIX System, plus the following features:
nFax Messaging allows you to handle faxes as easily as you handle voice mail. You 
can send, receive, store, scan, delete, skip, or forward faxes. This feature is fully 
integrated with voice messaging, so you can attach faxes to voice messages, for 
example. You can also create special mailboxes for each of your fax machines. 
These mailboxes accept fax telephone calls when the fax machine is busy and then 
deliver the fax to the fax machine when the fax machine is available
nTurn off AUDIX Call Answering allows you to turn off Call Answering in order to 
conserve system resources. You can create a message that tells callers they 
cannot leave a message, giving them another number to call, for example
nPre-Addressing allows you to address a message before recording it
nIntegrated Messaging allows you access and manage incoming voice, fax, and 
e-mail messages and file attachments from your personal computer or your 
telephone. A voice message will thus appear in your e-mail mailbox, for example, 
and vice versa. You can also set options to have just the message headers appear 
in the alternate mailbox. You can also create a voice or fax message by telephone 
and send it to an e-mail recipient
nText-to-Speech allows you listen to a voice rendering of text messages sent from a 
supported e-mail system and/or INTUITY Message Manager
nPrint Text allows you to print messages sent from a supported e-mail system 
and/or INTUITY Message Manager
nEnhanced Addressing allows you to send a message to up to 1500 recipients
nTransfer Restrictions allow you to control toll fraud by restricting transfers going 
through the voice messaging system
nInternet Messaging allows you to exchange messages (voice and text) with any 
e-mail address via the World Wide Web.
nLucent Voice Director allows you to address messages via spoken name, in 
addition to using touchtones to enter extensions or names. It also supports 
transferring to AUDIX subscribers, including those in other locations, by speaking a 
name.

Mode Code Interface
DEFINITY ECS supports an analog Mode Code interface for communications with 
I
NTUITY AUDIX and other voice mail systems using the same interface. This interface 
employs DTMF tones, line signals, and feature access codes, and allows I
NTUITY AUDIX 
to exchange data with the DEFINITY ECS without using a data link. Other adjunct 
vendors can engineer their products to use this interface.
Dual DCP I-Channels
Support the use of dual DCP I-channels for AUDIX networking. In this case, networking 
refers to the ability to send data files between AUDIX systems, not to communications 
with the switch.
INTUITY Lodging
Lucent Technologies INTUITY Lodging is a messaging system designed especially for 
lodging establishments such as hotels or other lodging providers such as hospitals or 
colleges. The system supplies guests with electronic mailboxes that store voice or fax 
messages. I
NTUITY Lodging serves as a private answering machine for each extension.
Hotel guests can leave messages for each other without going through the Attendant. For 
incoming calls, an Attendant transfers the call to the appropriate room. If the guest does 
not answer the call or if the line is busy, the call is automatically transferred to the guest’s 
voice mailbox, where the caller can leave a voice message.
A message-waiting indicator on the guest’s phone notifies the guest that the voice 
mailbox contains messages. Guests are assigned a password for accessing messages 
remotely. They can retrieve and save messages from any telephone, on or off premises.
INTUITY Conversant
The INTUITY CONVERSANT Voice Information System is an interactive voice-response 
system that automates phone-call transactions from simple tasks ,like routing to the right 
department, to complex tasks, such as registering college students or providing bank 
balances. It communicates with customers in natural-sounding, digitally recorded speech. 
And it performs — 24 hours a day and without the services of an operator.
The system can handle single or multiple voice-response applications simultaneously, 
and can serve up to 48 callers at once. It can operate by itself to dispense information or 
collect data, or it can work with a host computer to access a large database such as bank 
account records. With its speech-recognition capability, even rotary telephone users can
