Release 7.0 Enhancements (April 1999)
Release 7.0 Enhancements (April 1999)
Release 7.0 includes all Release 6.1 functionality, plus the
enhancements listed below.
■ MLS and Enhanced Tip/Ring (ETR) Telephone
Support
One of the most important new capabilities of MERLIN
LEGEND Release 7.0 is its support for MLS and ETR
telephones, allowing existing customers with either telephones
the ability to migrate to a MERLIN LEGEND Communications
System. The MLS telephones include the MLS-6
®
MLS-12D
include the ETR-6, ETR-18, ETR-18D, and ETR-34D. The
Business Cordless 905 telephone and the TransTalk™ 9000
, MLS-18D®, and MLS-34D®. The ETR telephones
Digital Wireless System are also supported.
The MLS, ETR, and Business Cordless 905 telephones, as well
as the TransTalk 9000 Digital Wireless System, require ET R
station ports. To provide support for these telephones and for
the TransTalk 9000 system, two new modules have been
designed:
— 412 LS-ID-ETR Module. The 412 LS-ID-ETR module is not
available. To connect ETR and MLS telephones to a MERLIN
LEGEND Communications System, use the 016 ETR
module.
station ports, including 6 with T/R functionality and 4 TTRs.
On the 016 ETR module, the first 10 ports are ETR ports
only—these ports do not have T/R functionality. The
remaining 6 ports (ports 11 through 16) can be programmed
to support either T/R or ETR, but not both simultaneously.
■ Expanded Digital Endpoint Connectivity
Release 7.0 increases the maximum number of digital
telephones supported from 127 to 200 by introducing a new 016
MLX module. In addition, each of the 200 ports can support an
MFM adjunct which increases the current 255 station endpoints
to 400.
— 016 MLX Module. Each 016 MLX module provides 16 digital
station ports and has an additional 32K of dual port RAM.
— Processor Module. The 016 MLX module can only be
utilized with the CKE4 or later processor module with
upgrade to R7.0 software. The CKE4 processor module
provides the lead to access the additional 32K of RAM on the
016 MLX module.
■ Voice Announce on Idle Only Option on MLX Telephones
Prior to Release 7.0, no options were available for disabling
intercom voice announcements at an MLX telephone when
busy. In Release 7.0, a new option—Voice Announce on IDLE
ONLY—is available with the existing Voice Announce feature.
This new option allows a user to receive intercom voice
announcements only when they are not active on another call.

Release 7.0 Enhancements (April 1999)
■ Priority Call Queuing
Priority call queuing provides the ability to:
— Place some callers ahead of others who are waiting for the
same agent group.
— Give key clients priority over others.
— Automatically increase the number of agents answering calls
during busy times, while continuing to offer callers the choice
to leave a message instead of waiting.
— Keep costs down by handling toll free calls (calls arriving on
800 and 888 lines) before processing calls on local lines.
Priority call queuing is accomplished in Release 7.0 by allowing
you to define a supportive relationship between calling groups.
Calls that arrive in one calling group can be processed by
another calling group when no one from the first calling group is
available to answer the call. Through system programming, a
calling group can be assigned a priority level between 1
(highest priority) and 32 (lowest priority) and then designated as
a support group for another group.
■ Calling Party Name on Caller ID
Release 7.0 continues to support Calling Party Number and
adds a new functionality for Calling Party Name. By
programming a button on the telephone or with a feature code
through centralized programming, users are able to toggle
between displaying the caller’s telephone number or the caller’s
name. In order to use this feature, users must subscribe to
caller identification from their local exchange carrier (LEC).
Calling Party Name can be 15 characters in length for MLX
telephones as well as for ETR and MLS telephones. Calling
Party Name is not recorded on SMDR reports. In addition,
neither Calling Party Name nor Calling Party Number are
displayed on analog multilin e telep hon es.
This feature requires loop-start (LS) trunks. The existing LS-ID
delay feature must be programmed for each line, as well. This
prevents Calling Party Number and Name information from
being lost when a call is answered too quickly.
Release 7.0 software also supports the Caller ID capability of
the 408 GS/LS-ID-MLX module. Although previously orderable,
the Caller ID capability of this module could not be used until
Release 7.0 software became available.

Release 7.0 Enhancements (April 1999)
■ MLX Headset Operation
Headset operation in Release 7.0 has been enhanced so that
MLX headset operation more closely mimics the handset
operation in the following ways:
— When a person is on a call using a headset and the headset
auto-answer is turned on, the user hears a short ring when
another call is coming in. In previous releases, this ring was
not provided.
— When a person receives a voice-announced call and handles
the call by using a headset and turning off the speakerphone,
the associated LEDs (the DSS button and the inside Auto
Dial button) for that extension at other telephones are lit. In
previous releases, the LEDs for that extension did not light at
the other telephones.
— When a reliable disconnect occurs on a headset-handled
call, the associated LEDs (the DSS button and the inside
Auto Dial button) for that extension at other telephones are
turned off. In previous releases, the LEDs for that extension
remained lit at the other telephones unless the user pressed
the Headset Hangup button.
■ Touch-Tone or Rotary Signaling
Beginning in Release 7.0, you can program tip/ring ports to use
rotary signaling. You can program any tip/ring port on an
individual basis (including ports on the 412 LS-ID-ETR and 016
ETR modules that are programmed for tip/ring operation). The
factory setting is that rotary signaling is disabled.
Whenever the system receives a rotary digit on a port, it
determines if the port is programmed as rotary-enabled. If the
port is rotary-enabled, the system processes the digit. If the port
is not rotary-enabled, the digit is rejected. Touch-tone digits are
always accepted by the port, regardless if it is rotary-enabled or
not.
■ Abandoned Call Information Reported to
MERLIN LEGEND Reporter
For abandoned calls, you are now able to identify the queue or
the agent where the call was aband one d. Th e MER LIN
LEGEND Release 7.0 software has been modified so that either
of the following occurs:
— If the caller hangs up while the call is in queue, the Auto
Login/Logout Group ID is entered into the Station Message
Detail Recording (SMDR) record.
— If the caller hangs up while the call is ringing at a group
member’s extension, that group member’s extension number
is entered into the SMDR record.

Release 6.1 Enhancements (August 1998)
Release 6.1 includes all Release 6.0 functionality plus the
enhancements listed below.
■ Private Networking
Release 6.1 enhances the functioning of the networked
MERLIN LEGEND Communications System in a number of
ways:
— Centralized Voice Messaging
— Group Calling Enhancements
— Transfer Redirect
— Direct Station Selector
— Call Forwarding
— SMDR
— Decrease in Call Set-Up Time
— PRI Switch Type Test
■ Centralized Voice Messaging
One or more MERLIN LEGEND Systems (Release 6.1 or later)
can share the voice messaging system (VMS) of another
MERLIN LEGEND System, provided the systems are directly
connected to the system with the VMS. In this configuration, the
system containing the VMS is known as the
the VMS is called
Voice Messaging includes the functions of voice mail,
Automated Attendant, and fax messaging. See the
Reference
Centralized Voice Messaging
for detailed information about Centralized Voice
Messaging.
Centralized Voice Messaging offers the following benefits:
— Private-networked MERLIN LEGEND Systems do not need a
local VMS. Having systems use a centralized VMS instead of
separate VMSs is more economical .
— Users who travel between sites can dial the same digits
anywhere in the privat e network to access the voice
messaging system. For example, a salesperson
headquartered in Cincinnati can dial the same four digits at
the company’s Los Angeles office to retrieve voice
messages.
— Productivity is enhanced because messages can be
forwarded and broadcast to all personnel within the private
network.
— Calling groups on networked systems can send overflow
coverage to a shared VMS, so that an incoming caller can
leave a message instead of waiting in a queue.
— The VMS can light the Message Waiting lights on multiple
MERLIN LEGEND Systems in a private network. This
greater ef fi ci ency saves time bec ause a us er on ly ha s to look

extensions, includi ng:
— Night Service. Night Service coverage can be provided
across a private network to a centralized Automated
Attendant, a non-local calling group, a QCC queue, a DLC,
or any individual extension on the remote system, such as a
night bell.
— Group Coverage. Group Coverage can be provided across
a private network to a VMS, a non-local calling group, a QCC
queue, a DLC, or any individual extension on the remote
system.
— Calling Group Overflow Coverage. Calling group overflow
coverage can be provided by a centralized VMS, a non-local
calling group, a QCC queue, a DLC, or any individual
extension on the remote system.
— Calls Directed to Another System. Lines connected to
remote systems can be answered by any extension
programmed to answer the call, such as a centralized
Automated Attendant or a system operator (QCC or DLC).
■ Transfer Redirect
When an Automated Attendant transfers a call to a non-local
extension, the transferring MERLIN LEGEND System monitors
the call to ensure that it is answered. If the non-local extension
is not available, or the call is not answered within the transfer
redirect timeout period (fixed at 32 seconds), the call stops
ringing at the non-local destination and is redirected to the
extension on the same system as the Automated Attendant that
is programmed to receive redirected calls. This redirect
extension can be a QCC queue, a calling group, or an individual
extension.
■ Direct Station Se lector
Now users can press a Direct Station Selector (DSS) button for
a non-local extension to make or transfer calls to that extension.
No busy indication, however, is displayed by the DSS for nonlocal extensions.
■ Call Forwarding
The Forward feature now can be used to send calls to non-local
extensions across the private network.

Release 6.1 Enhancements (August 1998)
■ SMDR
In addition to SMDR options for non-network calls placed to and
from the local system, system managers now can program
SMDR to log incoming and outgoing UDP calls, or they can
choose to log no UDP calls. The factory setting is to record all
UDP calls.
Customers who use a call accounting system may not want to
fill the database with calls coming and going across the private
network. These customers may choose not to log UDP calls.
■ Decrease in Call Setup Time
The setup time for a call across a private network has been
reduced by programming the number of UDP digits expected.
■ PRI Switch Type Test
A new maintenance test, the PRI Switch Type Test, has been
created to allow Lucent T e chnologies technicians or authorized
dealers to automatically determine if each end of the PRI
tandem trunks has been programmed correctly. The test works
for directly connected MERLIN LEGEND Systems, not for
DEFINITY
®
systems.
For a PRI tandem trunk to operate correctly between two
MERLIN LEGEND Systems, one system must have the PRI
Switch Type set to Network, and the other system must have
the PRI Switch Type set to PBX. If both ends of the PRI tand em
trunk are programmed the same, problems occur in the
communications between the two systems.
■ Service Observing
Service Observing allows one extension to listen in on
(observe) a call at another extension. A typical application of
this feature is that of a Customer Service supervisor ob serving
how a Customer Service representative handles calls.
The Service Observing group can listen to anywhere from one
extension to all extensions in the system, including other
Service Observers. Up to 16 Service Observing groups can be
programmed. The Service Observer and the observed
extension must be on the same system.
The observer activates Service Observing either by pressing a
Service Observing button and then dialing an extension
number, or by pressing a DSS or Auto Intercom button. The
Service Observer must use an MLX telephone to observe an
extension; the telephone at the observed extension can be of
any type.
A warning tone that alerts the observer, the observed extension,
and the caller that Service Observing is occurring can be set to
on or off through System Programming. The factory setting is
on.

■ Private Networks
In Hybrid/PBX mode systems only, MERLIN LEGEND
Communications Systems can be networked with one another
or with DEFINITY Enterprise Communications Server (ECS)
and ProLogix™ Communications Systems in private networks.
In previous releases, this functionality is available using tie
lines, but users handle calls between networked switches as
outside calls. In this release, dialing the pool access code is not
necessary for a call going from one networked switch to
another. Also, delay-start tie trunks or T1 trunks administered as
PRI can act as
Available for Hybrid/PBX mode systems, the private network
features of the MERLIN LEGEND Communications System
Release 6.0 provide the following advantages for
geographically dispersed organizational sites:
— Intersystem Calling. In a private network, users on one
local system can call extensions on other systems in the
network. Release 6.0 can support 2-, 3-, 4-, or 5-digit dial
plans. They dial these extensions as inside calls. To
implement this function, the system manager programs the
extension ranges of remote networked switches to create a
non-local dial plan. This programming does not actually
affect numbering on the remote system. To correctly set up
systems for transparent calling among non-local dial plan
extensions, the system manager assigns networking tie and/
or PRI tandem trunks to pools. Then he or she programs up
to 20 patterns, associated routes, Facility Restriction Levels
(FRLs), digit absorption, and digit prepending. This allows
ARS-like routing of non-local dial plan calls. In addition,
system managers can control whether calling name, calling
number, or both are shown at MLX display telephones for
incoming calls across PRI tandem trunks.

Release 6.0 Enhancements (February 1998)
— Toll Savings. Private networked trunks may allow you to
realize significant cost savings on long-distance and toll calls
by performing tandem switching in the following two ways:
— Callers on a local system, or individuals dialing in to
remote access at a local system, can reach the public
switched telephone network (PSTN) via outside trunks
connected to other systems in a private network, avoiding
toll charges or decreasing the cost of toll calls. No special
dialing is required. For example, an organization might
have a main office in Boston and a subsidiary office in
New Jersey connected by networked private tandem
trunks between two systems. A user in the New Jersey
office who wishes to make an outside call to the 617 area
code (Bost o n) ca n d o so t hr o ugh a l i ne /t r un k co nn ec te d t o
the system in Boston. For example, he or she might dial,
916175551211. The local ARS tables would route this
call over the private networked trunks and use the ARS
tables of the remote system in Boston to route this call.
The system managers at each end of a private network set
up ARS and Remote Access features to implement this
functionality.
— In addition, local organizations or incoming DID calls use
private networked trunks to make intersystem calls
between networked systems, which may be
geographically distant from one another, also resulting in
toll savings.
— Service Cost Savings. In addition to toll call savings, there
are two ways that organizations can save on service costs
incurred from telecommunications providers that provide
public switched telephone network access:
— Y ou order a point to point T1 facility from a service
provider, then use system programming to set it up for PRI
signalling. As necessary, a service provider can provide
amplification on the T1 facility, but does not supply
switching services.
— You can tailor your use of PRI B-channels with drop-and-
insert equipment that allows fractional use of B-channels
for dedicated data/video communications between
systems at speeds greater than 64 kbps per channel or
128 kbps for 2B data, while keeping the remaining Bchannels available for PRI voice traffic. The PRI
D-channel must remain active.
— Y ou can tailor use of T1 channels to support both T1-
emulated tandem tie service and T1 Switched 56 service
for data communications at 56 kbps per channel, allowing
2B data transfers at 112 kbps. You can also use drop-andinsert equipment to provide fractional T1 use.
— Voice Mail and Auto Attendant. Networked systems (prior
to Release 6.1) should have their own local voice mail and/or
auto attendant applications as well as their own external
alerts and Music-On-Hold sources. A single Auto Attendant,
however, can transfer calls throughout the network. It can
answer only those calls that arrive on the PSTN facilities of
the system where it is connected.

Release 6.0 Enhancements (February 1998)
Although many features are available using tie trunks for
network connectivity, PRI tandem trunks provide greatly
enhanced features and faster call setup. For this reason, PRI is
recommended over tie functionality in private networks.
■ Group Calling Enhancements
Release 6.0 and later systems include Group Calling features
that enhance group calling operations.
■ Queue Control
The system manager can control the maximum number of calls
allowed in the primary calling group queue for calls that arrive
on certain facilities often assigned to calling groups. When the
number of the calls in queue reaches the programmed
maximum, subsequent callers receive a busy signal.
Queue control applies to calls received on the following types of
facilities:
— Direct Inward Dialing (DID)
— PRI facilities programmed for dial-plan routing
— All calls transferred from a voice messaging interface (VMI)
port
— Dial-in Tie
Queue control also applies to internal calls to a calling group
and calls to a calling group through the Queued Call Console
(QCC).
Internal calls that dial #0 or #800 and are directed to a calling
group administered as P osition-Busy Backup are eligible for
queue control. Calls that come in on a trunk assigned to the
QCC are not eligible for queue control if the call is directed to a
calling group designated as Position-Busy Backup.
Remote-access calls to a calling group, coverage calls directed
to a calling group, calls directed to a calling group through QCC
Position-Busy Backup, and all other outside calls are not eligible
for queue control.
■ Prompt-Based Overflow
System managers can activate the Prompt-Based Overflow
option. This option allows callers waiting in queue and listening
to a delay announcement to press the # key in order to reach
the overflow receiver for the group, which may be the QCC
queue or another calling group (including a calling group
assigned for a voice mail system).
All three overflow distribution options—based on the number of
calls, the time a caller has waited, and according to the caller’s
prompt—may be used at one time. In this case, time-based and
number-of-calls based options take precedence over overflow
distribution based on the caller’s prompt.
When prompt-based overflow distribution is used, an extra TTR
must be provided for each delay announcement device
assigned to the associated calling group. The delay
announcement informs the caller of the # key option to exit the
queue and leave rather than waiting for an agent. If no TTR is
available when a calling group call arrives, the call is not sent to
a delay announcement extension.

■ Centrex Transfer via Remote Call Forwarding
Centrex Transfer via Remote Call Forwarding can be used in all
system modes of operation to send outside calls to a remote
telephone number or another Centr ex station. In this context,
the term
outside calls
refers to calls from outside the
communications system, which may originate at extensions in
the Centrex system that are not connected to the local MERLIN
LEGEND Communications System.
An outside call that uses this feature is defined as a call that
arrives on an analog Centrex loop-start line at the MERLI N
LEGEND Communications System. It may arrive directly or be
transferred without consultation or without transfer supervision
(in the case of an automated attendant). The forwarding call to
the outside number is made on the same line/trunk on which the
call arrived, conserving system facilities. The following
considerations and rules apply:
— Only outside Centrex calls are forwarded using this feature.
— The system must be equipped with analog loop-start Centrex
lines and
facilities. Loop-start lines do not have to provide reliable
all
loop-start lines in the system must be Centrex
disconnect for use by the Centrex Transfer via the Remote
Call Forwarding feature.
— T o transfer calls outside the Centrex system, the organization
must subscribe to a Centrex trunk-to-trunk transfer feature.
Activating Centrex Transfer via Remote Call Forwarding is just
like activating regular Remote Call Forwarding and requires that
Remote Call Forwarding be enabled for the extension.
However, the user dials * instead of a dial-out code, and a
Pause character may be required after the *. The Centrex
service provider determines whether the Pause is needed.
Pause cannot be originated from a single-line telephone or a
remote access user. A multiline telephone user in the local
system must enter an authorization code to activate the feature.
A remote access user may activate the feature without using an
authorization code. Barrier code requirements, however, do
apply.
■ Authorization Cod es an d
Remote CallForwarding
In Release 6.0 and later Key or Hybrid/PBX mode systems,
forwarding features (including Centrex Transfer via Remote Call
Forwarding, but excluding Follow Me) can be activated or
deactivated at a multiline telephone by entering the
authorization code for the extension from which calls are to be
forwarded. The user enters the authorization code, then
activates or deactivates the forwarding feature in the normal
fashion. Th is i s e spec iall y us ef ul fo r a s ing le- lin e te leph one use r
who must include a Pause character in a Centrex Transfer via
Remote Call Forwarding dialing sequence, because the
character cannot be dialed at a single-line telephone. It is also
useful when activating Call Forwarding or Remote Call
Forwarding at phantom stations or via remote access (for
example, from another switch in the network). No other features
can be used by entering an authorization code in this fashion.

Pocket Reference
555-670-116
Release 5.0 Enhancements (June 1997)
Release 5.0 Enhancements (June 1997)
Release 5.0 includes all Release 4.2 functionality, plus the
enhancements listed below.
■ Computer Telephony Integration (CTI)
Beginning with Release 5.0, a PassageWay
Services CTI link from the MERLIN LEGEND Communications
System to a LAN server running Novell
allows Lucent Technologies-certified telephony applications to
control and monitor MLX and analog multiline telephone (BIS
only) operations. The physical connection for the CTI link is an
MLX port on a 008 MLX or 408 MLX module on the MERLIN
LEGEND Communications System control unit and an ISDN
link interface card plugged into the customer’s server. The
feature is available for Hybrid/PBX mode systems only.
NOTES:
•The NetWare server software version must be 3.12, 4.1,
or 4.11.
•The 008 MLX and 408 MLX modules must have a
firmware vintage other than 29. If the module has
firmware 29, programming a CTI link on the module is
prevented. An earlier or later vintage firmware is
supported.
■ Basic Call Control
A CTI link application on a user’s computer can assume basic
call control of the user’s analog multiline or MLX telephone’s SA
buttons. Basic call control includes:
— Answering calls arriving on an SAbutton.
— Making calls from an SAbutton.
— Hanging up calls.
— Holding and retrieving a call on hold at the user’s extension.
NOTE:
Transfer and three-way conference, when handled through a
CTI link application, provide the original caller’s calling
number information or other information to the transfer
receiver or new conference participant, if the user has screen
pop capability.
■ Screen Pop
Screen pop occurs when the calling number, called number, or
other user-defined identifier (such as an account code that a
voice-response unit prompts the caller to dial) is used to display
a screen associated with the far-end party. For example, Caller
ID services can be used to support screen pop on a system that
includes a CTI link; using the calling party number as a
database key code, information about a caller automatically
appears on the user’s computer screen when the call arrives at
the extension. Depending on the application, screen pop may
be available for calls that arrive on line buttons other than SA
buttons and/or calls that are answered manually at the
telephone rather than by the application.
Screen pop can occur on incoming calls from the following
sources:

MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Release 5.0 Enhancements (June 1997)
— Calling gr oup distribution.
— ISDN PRI Routing by Dial Plan.
— An extension on the MERLIN LEGEND Communications
System.
— Remote access.
NOTE:
In the case of remote access calls, the only information
that the application can collect about the caller is the
remote telephone number.
— A transfer of a call that was answered by a voice response
unit.
— A transfer, redirection, or conference of a call that was
answered at a Direct-Line Console (DLC) or at a Queued
Call Console (QCC).
NOTES:
•DLCs may use CTI applications. If they do, they perform
the same way as other extensions. A DLC assigned to
use a CTI link application is a monitored DLC. When a
DLC is used as a regular operator console and is not
using a CTI link extension, it is non-monitored.
•Calls to a QCC or a DLC not using a CTI application do
not initia te screen pop at the operator position.
However, when an operator directs a call to an
extension using a CTI application, caller information
does initiate screen pop. If the DLC is non-monitored,
screen pops can occur after the DLC releases the call.
•Calls transferred from Cover buttons on non-monitored
DLCs do not initiate screen pop at the destination
extension.
■ HotLine Feature
The Release 5.0 HotLine feature is designed for retail sales,
catalogue sales, and other types of businesses and
organizations, and is available in all three modes of system
operation. It allows a system manager to program a single-line
telephone extension c onnected to an 008 OPT, 012, or 016
module as a HotLine. When a user lif ts the handset at the
HotLine extension, the telephone automatically dials the inside
extension or outside telephone number programmed as the first
Personal Speed Dial number (code #01) for the extension. The
system does not permit calls to be transferred, put on hold, or
conferenced. (A user can press the telephone’s Hold button, if it
has one, to put a call on local hold, but the call cannot be
redirected in any way. Switchhook flashes are ignored.)
Personal Speed Dial codes can be programmed from the
extension prior to HotLine assignment (a system programming
function). Alternatively, a Personal Speed Dial code can be
programmed from the single-line telephone after HotLine
operation is assigned. However, because of security
considerations, this is a one-time opportunity. Once the
Personal Speed Dial number is programmed, any changes to it
or any other extension programming must be performed using
centralized telephone programming.

MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Release 5.0 Enhancements (June 1997)
Any type of inside or outside line that is norm ally available to a
single-li ne telephone can be assigned to a HotLine extension.
Generally, the HotLine telephone does not receive calls, and its
lines should be set to No Ring.
SECURITY ALERT:
!
If a HotLine extension accesses a loop-start line, that line
should provide reliable disconnect and be programmed for
reliable disconnect. Otherwise, a user at the extension may
be able to stay on the line after a call is completed and then
make a toll call.
■ Group Calling Enhancements
Release 5.0 and later systems include Group Calling features
that enhance group calling operations.
■ Most Idle Hunt Type
In addition to the Circular (factory setting) and Linear hunt types
supported in earlier releases, a third hunt type distributes calling
group calls in an order based on which agent has waited the
longest since transferring or hanging up on an incoming calling
group call. For some appl ications, this hunt type is more
efficient than the circular type because it takes into account the
varying duration of calls. The system distributes calls based on
when an agent last completed a call, not on when he or she last
received one. This hunting method ignores non-calling group
calls. For example, if an agent transfers a call that arrived on a
line not assigned to the calling group, the calling group
member’s most-idle status is unaffected.
■ Delay Announcement Devices
The system manager can designate as many as ten primary
delay announcement devices per group, rather than the single
device for each group that is available in Rel ease 4.2 and
earlier systems. Furthermore, an additional secondary delay
announcement device can be specified, for a total of ten
primary device extensions and one secondary device extension
per group.
A primary delay announcement device operates in the same
fashion as a single delay announcement device, playing once,
as soon as it is available, for the caller who has waited the
longest for a calling group agent and has not heard a primary
delay announcement. If a secondary announcement device is
used, it can use the factory setting, which plays the
announcement once, or it can be set to repeat the
announcement after a certain amount of time. The system
manager programs the ti me (0–900 seconds) between
announcements. This setting controls both the interval between
primary and secondary announcements and the interval
between repetitions of the secondary announcement, if it is set
to repeat. (See “Calling Group Options” in Chapter 4 of
for guidelines on setting the delay.)

Release 5.0 Enhancements (June 1997)
The primary and secondary announcement options, when used
together, allow an initial message to play for callers, followed by
a repeating announcement that, for example, urges callers to
stay on the line and wait for a calling group member.
Two or more groups may share an announcement device.
A primary delay announcement device can be programmed as
a secondary delay announcement device.
■ Enhanced Calls-in-Queue Alarm Thresholds
Three Calls-in-Queue Alarm thresholds can be set to more
clearly indicate the real-time status of the calls waiting in the
queue according to the behavior of programmed Calls-in-Queue
Alarm buttons. In earlier releases, only one Calls-in-Queue
Alarm Threshold setting is available to activate the LEDs at
programmed Calls-in-Queue Alarm buttons for a calling group.
Using all three levels, the system manager sets Threshold 3 to
the highest value, Threshold 2 to a middle value, and Threshold
1 to the lowest value. A Calls-in-Queue Alarm button indicates
the severity of the alarm conditions in the following ways:
— If the number of waiting calls is less than the value
programmed for Threshold 1 or drops below that level, the
LED is unlit.
— If the number of waiting calls is greater than or equal to the
Threshold 1 value but less than the Threshold 2 value, the
LED flashes.
— If the number of waiting calls is greater than or equal to the
Threshold 2 value but less than the value for Threshold 3, the
LED winks.
— If the number of waiting calls is greater than or equal to the
highest value, Threshold 3, the LED ligh ts stead ily.
NOTE:
A Direct Station Selector (DSS) button that is used as a
Calls-in-Queue Alarm button can only indicate two threshold
levels, either by flashing or by lighting steadily. If a calling
group must use this type of Calls-in-Queue Alarm button, only
two threshold levels should be pr ogrammed.
If all three thresholds are set to the same value, the result is one
threshold only with LED state either off or on (steady). If two
values are the same, then the result is two alarm levels (flash,
steady). The factory setting is one call for all three thresholds,
with LED states of off and steady.
An external alert signals only when the number of calls in the
queue meets or exceeds the program m ed Threshold 3 value.
■ MLX-5 and MLX-5D Telephones
The MLX-5 nondisplay and MLX-5D display telephones are
compatible with all system releases. The display telephone
includes a 2-line by 24-character display, and both telephones
come with five line buttons. In systems prior to Release 5.0, the
MLX-5 and MLX-5D telephones are treated as MLX-10 and
MLX-10D telephones, respectively. As of Release 5.0, the
system recognizes the MLX-5 and MLX-5D telephones as 5button telephones.

Release 4.2 includes all Release 4.1 functionality, plus the
enhancements listed below. There are no hardware changes for
Release 4.2.
■ Additional Network Switch and Services Options
for ISDN Primary Rate Interface (PRI)
Release 4.2 of the system supports connectivity to MCI
local exchange carrier (LEC) PRI services and to the following
central office switch types (in addition to the 4ESS™ and

MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Release 4.2 Enhancements (June 1997)
■ Improvements to Station Message Detail
Recording (SMDR) and Support for
MERLIN LEGEND Reporter Application
The SMDR feature is enhanced to provide more details about
calling group agent activities and to help system managers
assess the effectiveness of call centers in terms of both agent
performance and the adequacy of facilities to handle inbound
calls. These improvements apply to calling groups that are
programmed as Auto Login or Auto Logout type. The SMDR
and MERLIN L EGEND Reporter features listed are
administrable:
— TALK Field. For Auto Login and Auto Logout calling groups,
the TALK field records the amount of time a calling group
agent spends on a call.
— DUR. (DURATION) Field. For Auto Login and Auto Logout
calling groups, call timing begins when a call arrives at the
MERLIN LEGEND Communications
preset number of seconds. Call timing ends when the call is
System and not after a
disconnected; either the caller or the agent hangs up. This
allows the system manager to determine how long a caller
waited for an agent’s attention.
— Coding of Calls on Reports. An asterisk (*) appears in the
call record when:
— A call is not answered by an Auto Login or Auto Logout
calling group agent and is abandoned while waiting for an
agent.
— The call is answered by someone not a member of an
Auto Login or Auto Logout calling group.
An exclamation point (!) signals that an Auto Login or Auto
Logout agent handled a call that was answered by
someone who was not a member of that Auto Login or
Auto Logout with Overflow group. An ampersand (&) in the
call record indicates that the group’s overflow receiver
answered the call.
■ MERLIN LEGEND Reporter
MERLIN LEGEND Reporter provides basic call accounting
system reports for all incoming calls to Auto Login or Auto
Logout type calling groups. MERLIN LEGEND Reporter assists
in determining the effectiveness of calling group agents,
assessing the level of service provided to callers, and
ascertaining whether adequate incoming telephone lines and
agents are available to handle peak-call load. The SMDR Talk
Time option sets up special call records used by MERLIN
LEGEND Reporter. The default is off, in which case the Release
4.0 SMDR reports are available. If the option is set to on, the
following new reports are provid ed:

■ Maintenance Enhancements
■ Change to Permanent Error Alarm
Beginning with Release 4.2, the most recent permanent error
alarm is not shown on the System Error Log menu screen but is
available as an option from that screen. For details, refer to the
maintenance section of the technician guide,
Programming, and Maintenance.
■ Enhanced Exten sion Information Report
Beginning with Release 4.2, the Extension Information Report
includes the Extension Status and supervisory mode of each
Installation,
extension.
Release 4.1 Enhancements (June 1997)
Release 4.1 includes all Release 4.0 functionality, plus the
enhancements listed below. There are no hardware changes in
Release 4.1.
■ Coverage Timers Programmed for
Individual Extensions
Beginning with Release 4.1, coverage timers, which control the
duration of the delay before calls are sent to each level of
coverage, are changed as follows:
— The Group Coverage Ring Delay (1–9 rings) is programmed
on individual extensions and replaces the Coverage Delay
Interval programmed systemwide in previous releases.
— The Primary Cover Ring D elay (1–6 rings) and Se condary
Cover Ring Delay (1–6 rings), prog ra mm ed on in divi d ual
extensions, replace the Delay Ring Interval programmed
systemwide in previous releases.
These enhancements allow the system manager to customize
coverage call delivery to match individual extensions’ callhandling requirements.
■ Night Service with Coverage Control
Beginning with Release 4.1, a system manager can enable the
Night Service Coverage Control option to automatically control
the status of telephones programmed with Coverage VMS
(voice messaging system) Off buttons, according to Night
Service status.
When Coverage Control is enabled and the MERLIN LEGEND
Communications System is put into Night Service, all
programmed Coverage VMS Off buttons are automatically
turned off (LED is unlit) and all eligible outside calls are sent to
the assigned voice messaging system calling group with normal
ringing delay. When Night Service is deactivated during the day,
all programmed Coverage VMS Off buttons are automatically
turned on (LED is lit) and voice mail coverage is disabled for
outside calls.

Release 4.0 Enhancements (March 1996)
Users can override the Coverage VMS Off button status at any
time by pressing the programmed Coverage VMS Off button to
turn the LED on or off.
■ Night Service Group Line Assignment
Beginning with Release 4.1, a system manager can assign lines
to Night Service groups to control handling of after-hours calls
received on individual lines. This capability replaces the
automatic assignment to Night Service groups of only those
lines that ring on the Night Service operator console. An outside
line must be assigned to a Night Service group to receive Night
Service treatment.
With this enhancement, Night Service can be activated and
deactivated on lines that do not appear on operator consoles
(for example, personal lines), and lines appearing at operator
positions can be excluded from Night Service.
■ Forward on Busy
Beginning with Release 4.1, the Forward, Follow Me, and
Remote Call Forward features are enhanced to remove the
requirement that a call be ringing at an extension before it can
be forwarded. With the Forward on Busy enhancement, a call to
an extension with no available SA or ICOM buttons is forwarded
immediately to the programmed destination, preventing the
caller from hearing a busy sign al from the intended call
recipient’s extension.
■ Maintenance Testing for BRI Facilities that Are
Part of Multiline Hunt Groups (MLHGs)
Beginning with Release 4.1, the NI-1 BRI (National Integrated
Services Digital Network-1 Basic Rate Interface) Provisioning
Test Tool is enhanced to include testing for BRI facilities that are
part of Multiline Hunt Groups (MLHGs).
The NI-1 BRI Provisioning Test To ol is used by Lucent
Technologies maintenance personnel on MERLIN LEGEND
Communications Systems that include an
800 NI-BRI module. Technicians use the tool during system
installation and maintenance to test the functionality of the BRI
lines and to report analyzed results.

An expanded dial plan supports up to 200 tip/ring devices.
■ Support for National ISDN BRI Service
This service (Hybrid/PBX and Key modes) provides an
alternative to loop-start and ground-start lines/trunks for voice
and digital data connectivity to the central office. Each of the
two B-channels (
voice and one data call at any given time. The data speeds on a

■ New Control Unit Modules
Release 4.0 supports a new NI-BRI line/trunk module and a
higher-capacity tip/r ing mod ule.
■ 800 NI-BRI Module
This new module connects NI-BRI trunks to the MERLIN
LEGEND System for voice, high-speed data, and video
transmission.
■ 016 Tip/Ring Module
This new module supports a 200-extension dial plan by
providing 16 ports for tip/ring devices. Applications that use a
tip/ring interface can connect to this board. All 16 ports can ring
simultaneously. Four touch-tone receivers (TTRs) are included
on the module as well. The module’s ringing frequency (default
20 Hz) can be changed, through programming, to 25 Hz for
those locations that require it.
■ Downloadable Firmware for the
016 (T/R) and NI-BRI Modules
The Personal Compute r Memory Card Int ernat ional Assoc iatio n
(PCMCIA) technology, introduced in Release 3.0, continues to
support these two modules for installation and upgrade in
Release 4.0. A Release 3.0 or later processor is required for
PCMCIA technology.
■ Support for 2B Data Applications
A Lucent Technologies-certified group and desktop video
application can use two B-channels to make video/data calls
when connected to a sing le MLX extension jack programmed
for 2B data. The 2B data devices must be equipped with
ISDN-BRI interfaces. NI-1 BRI, PRI, or T1 Switched 56 facilities
support 2B data communications at 112 kbps (using two
56-kbps channels) or 128 kbps (using two 64-kbps B-channels).
This feature is available for Hybrid/PBX and Key modes only.
■ Support for T1 Switched 56
Digital Da ta Transmission
For Hybrid/PBX and Key mode systems, Release 4.0 expands
support of T1 functionality by providing access to digital data
over the public switched 56-kbps network, as well as to digital
data tie-trunk services. Users who have T1 facilities for voice
services can now use them for video or data calls at rates of 56
kbps per channel (112 kbps for video calls using 2B data). The
Release 4.0 offering also includes point-to-point connectivity
over T1 tie trunks, allowing customers to connect two MERLIN
LEGEND Communications Systems or a MERLIN LEGEND
Communications System with a Lucent Technologies DEFINITY
G1.1 Communications System or DEFINITY Enterprise
Communications Server. The two communications systems can
be co-located or can be at different sites.

MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Release 4.0 Enhancements (March 1996)
■ Forwarding Delay Option
Each user can program a Forwarding Delay setting for the
Forward, Remote Call Forwarding, or Follow Me features. The
forwarding delay is the number of times that a call rings at the
forwarding extension before the call is sent to the receiver. The
delay period gives the original call recipient time to answer or to
screen calls by checking the displayed calling number (if
available). The delay can be set from 0 to 9 rings. The factory
setting for the forwarding delay is 0 rings (no delay).
■ Voice Announce on Queued Call Console
The system manager can enable the fifth Call button on a QCC
console (Hybrid/PBX mode only) to announce a call on another
user’s speakerphone (providing the destination telephone has a
voice announce-capable SA button available). A QCC cannot
receive voice-announced calls; they are received as ringing
calls. The factory-set status for the fifth Call button is voice
announce disabled.
■ Time-Based Option for
Overflow on Calling Group
time
Release 4.0 has added a
to the previous
number of calls
limit for calls in queue in addition
limit. If the Overflow Threshold
Time option is set to a valid number between 1 and 900
seconds, calls that remain in the calling group queue for the set
time are sent to the overflow receiver. If the overflow threshold
time is set to 0, overflow by time is turned off. The factory-set
time limit is 0 seconds (off).
■ Single-Line Telephone Enhancements
The following changes enhance the performance of single-line
telephones:
— Disable Transfer. Through centralized telephone
programming, the system manager can disable transfer by
removing all but one SA or ICOM button from the extension.
— No Transfer Return. When a handset bounces in its cradle,
the system interprets this as a switchhook flash and attempts
to transfer a call. When the transfer attempt period expires,
the user’s telephone rings. Release 4.0 eliminates this
unintended ringing by disconnecting the call in situations
where a switchhook flash is followed by an on-hook state and
a dial tone is present.
— Forward Disconnect. All ports on 008 OPT, 012, and 016
modules now send forward disconnect to all devices
connected to them when forward disconnect is received from
the central office. This enhancement prevents the
trunk/line from being kept active when one end disconnects
from the call. If an answering machine is connected to the
port, it does not record silence, busy tones, or oth er usele ss
messages. This operation is not programmable.

MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Release 3.1 Enhancements (March 1996)
■ Seven-Digit Pas sword for SPM
Release 4.0 has increased system security by requiring a 7-digit
password for system managers or technicians who use System
Programming and Maintenance (SPM) to perform programming
or the Trunk Test procedure. This password is for use in
addition to a remote access barrier code.
Release 3.1 Enhancements (March 1996)
Release 3.1 includes all Release 3.0 functionality, plus the
enhancements listed below.
■ Call Restriction Checking for Star Codes
Beginning with Release 3.1, a system manager can add star (*)
codes to Allowed and Disallowed Lists to help prevent toll fraud.
Star codes, typically dialed before an outgoing call, enable
telephone users to obtain special services provided by the
central office. For example, in many areas, a telephone user
can dial *67 before a telephone number to disable central
office-supplied caller identification at the receiving party’s
telephone. You must contract with your telephone service
provider to have these codes activated.
When users dial star codes, the system’s calling restrictions
determine whether the codes are allowed. If they are allowed,
the system’s calling restrictions are reset, and the remaining
digits that the users dial are checked against the calling
restrictions.
■ Trunk-to-Trunk Transfer Set for Each Extension
This enhancement to the Transfer feature enables the system
manager to allow or disallow trunk-to-trunk transfer on a per extension basis. In Release 3.1 and later systems, the default
setting for all extensions is restricted.
■ Programmable Second Di al Tone Timer
The system manager can assign a second dial tone timer to
lines/trunks, in order to help prevent toll fraud (for example,
when star codes are used). After receiving certain digits dialed
by a user, the central office may provide a second dial tone,
prompting the user to enter more digits. If this second dial tone
is delayed, and the user dials digits before the central office
provides the second dial tone, there is a risk of toll fraud or
misrouting the call. The second dial tone timer enables the
system manager to make sure that the central office is ready to
receive more digits from the caller.
■ Security Enhancements
The sections below outline security measures that are
implemented in Release 3.1 and later systems.

Release 3.1 Enhancements (March 1996)
■ Disallowed List Including Numbers Often
Associated with Toll Fraud
A factory-set Disallowed List 7 contains default entries, which
are numbers frequently associated with toll fraud. By default,
Disallowed List 7 is automatically assigned to both generic and
integrated voice messaging interface (VMI) ports used by voice
messaging systems. The system manager can manually assign
this list to other extensions.
■ Default Pool Dial-Out Code
Restriction for All Extensions
The default setting for the pool dial-out code restriction (Hybrid/
PBX mode only) is restricted. No extension or remote access
user with a barrier code has access to pools until the restriction
is removed by the system manager.
■ Default Outward Restrictions for VMI Ports
Ports assigned for use by voice messaging systems (generic or
integrated VMI ports) are now assigned outward restrictions by
default. If a voice messaging system must be allowed to call out
(for example, to send calls to a user’s home office), the system
manager must remove these restrictions.
SECURITY ALERT:
!
Before removing restrictions, it is strongly recommended that
you read Appendix A, ‘‘Customer Support Information,” in
System Programming.
■ Default Facility Restriction
Level (FRL) for VMI Ports
The default Au tomat ic Rout e Se lect io n (AR S) F RL f or VMI p ort s
is 0, restricting all outcalling.
■ Default for the Default Lo cal Table
The default Automatic Route Selection (Hybrid/PBX mode onl y)
FRL has changed to 2 for the Default Local table. System
managers can easily change an extension’s default FRL of 3 to
2 or lower to restrict calling. No adjustment to the route FRL is
required.
■ New Maintenance Procedure for Testing
Outgoing Trunks
Technicians must enter a password in order to perform trunk
tests.

Release 3.0 Enhancements (August 1994)
— Inspection of Lines/Trunks displays only those lines and
trunks configured on system rather than all 80 facilities.
— Extensions and facilities in Maintenance Busy (both manual
and automatic) can be identified by the maintenance monitor.
■ User Features
— Security. The Remote Access feature allows people at
remote locations to enter the system by dialing the number of
a line or trunk designated for remote access. The system can
be programmed to require the remote user to dial a barrier
code (a type of password) after reaching the system. In
earlier versions, the systemwide barrier code length is fixed
at four digits. Release 3.0 allows a systemwide barrier code
length ranging from a minimum of four digits to a maximum of
11 digits, with a factory setting of seven digits. SMDR records
are enhanced to provide information for remote access calls.
If the remote access call is received on a facility providing
Caller ID information (see below), the SMDR report can help
trace the call.
— Caller ID. Caller information (telephone number) is furnished
to MLX display telephones by an 800 GS/LS-ID module
using the LS (loop-start) option. This allows customers to
screen calls before answering the telephone, as well as
providing calling party information for use with various
applications. This function is available only when the
customer subscribes to caller identification service from the
telephone company, if the telephone company supports that
service.
— Shared System Access (SSA). A telephone may have up to
27 Shared SA buttons to expand extension coverage.
— Authorization Codes. The Authorization Code feature
allows you to make calls using your calling privileges when
you are dialing from an extension other than your own. When
you enter your authorization code (ranging from 2 to 11
characters and unique across the system), the privileges and
restricti ons assigned to your home extension override the
current restrictions at the host extension. This includes toll
restriction, outward restriction, Facility Restriction Level
(FRL), Allowed Lists, Disallowed Lists, Night Service
Exclusion List, and Dial Access to Pools. All other functions
on the telephone are those of the local telephone, not the
home extension.
Authorization codes can also be used for the purpose of call
accounting through the SMDR printout. The SMDR account
code field can hold either the authorization code extension
number or the authorization code itself.
— Direct Voice Mail. If your company has voice mail, this
feature allows you to dial a co-worker’s voice mailbox directly
without ringing that person’s extension. Direct Voice Mail is
especially useful for transferring calls when a co-worker is
not available.

applications), AT&T Set (extension programming interface),
and Log Viewer (call log application). PassageWay Direct
Connection Solution (Release 2.0) is the version supported
on MERLIN LEGEND Communications System Release 3.0.
— PagePal™. PagePal connects several paging systems to the
MERLIN LEGEND Communications System. No other
system adapter is necessary for loudspeaker paging.
— Fax Attendant 2.1.1. Fax Attendant Release 2.1.1, which
co-resides with AUDIX Voice Power on the IS III Release 1.2
platform, provides the same functionality as earlier versions,
plus the following enhancements:
— Personal Fax Messaging. Inbound faxes can be stored
until the subscriber asks that they be printed, at any fax
machine he or she specifies, on company premises or
offsite (when the subscriber retrieves fax messages
remotely).
— Fax Mail. Allows subscribers to send fax messages, get
fax messages, record personal greetings, and program
outcalling.
— Fax Broadcast. Provides a simple way to send one fax to
as many as 1000 fax numbers.

plus the enhancements listed below.
■ Operational
System operational enhancements include the following:
— When a call is forwarded to a multiline telephone that has an
Auto Dial or DSS button programmed for the forwarding
telephone, the green light next to the Auto Dial or DSS button
for the forwarding telephone does not flash.
— People answering calls received on Cover bu ttons are
allowed to generate touch tones if their telephones are not
outward- or toll-restricted.
— Calls received on personal lines with Do Not Disturb on go
immediately to coverage instead of waiting for the coverage
delay interval.
— A call put on hold at a Cover button can be added to a
conference by someone who has a personal line for the call.
— A call put on hold at a Cover button can be picked up by any
person who has a personal line for the call.
— Calls that have been put on hold at a Cover, SA, Shared SA,
or Pool button can be picked up by a person who has a
personal line button for the call.
— An inside call on hold at an SA button can be pick ed up and
transferred by any person with a Shared SA button
corresponding to the button with the held call.
— Calls that are on hold awaiting transfer can be picked up by
any user who has a personal line for the call.
— Beginning with Integrated Solution III Version 1.2, the
automatic reconciliation program that was run automatically
at 3:00 a.m. is disabled and can be invoked manually from
the User Maintenance menu.
— If an extension is programmed for Forced Account Code
Entry, account codes do not have to be entered when using a
programmed Loudspeaker Paging button. In addition, an
SMDR recor d is not generated for calls made to paging
ports.
— When an MLX telephone, other than an MLX-20L, is plugged
into an MLX port and the Personal Directory does not contain
any entries, the allocation of the Personal Directory resource
is released. If there are any entries in the Personal Directory,
the Personal Directory allocation and the entries in the
Personal Directory are saved in the MLX port.
— SMDR call records for calls made on PRI facilities are more
accurate than SMDR call records for calls made on non-PRI
facilities. Outgoing calls made on PRI facilities receive
“answer supervision.” Consequently, SMDR timing for calls
made on PRI facilities begins when the call is answered.
Timing for calls made on non-PRI facilities begins when
dialing is completed. Therefore, an SMDR call record is not
generated when a call made on a PRI facility is not answered
at the far end.

SMDR report are changed for both the Basic and ISDN
report formats.
— An 012 port that is programmed as a generic voice
messaging interface (VMI) port can transfer an outside call to
an outside number.
— In a system where the transfer audible option is programmed
for Music-On-Hold and a music source is provided, outside
callers who are transferred to a calling group and are waiting
in the queue or who are parked or camped-on, hear music
while they are waiting. Internal callers never hear music on
hold while waiting in the calling group queue or when they
are parked, camped-on, or being transferred to another
extension.

— The control unit covers for the MERLIN LEGEND
Communications System are the same easy-to-use covers
as those for the MERLIN II Communications System.
— A new 012 (tip/ring) module [apparatus code 517G13 (28) or
higher letter] contains a built-in ring generator. The maximum
ring equivalency number (REN) supported is 2.2, and the
module will ring four ports at one time. Bridging of single-line
telephones is not supported because of poor transmission
quality.
— A new 008 OPT module (labeled “with RING GEN.”) contains
a built-in ring generator. It rings four ports at a time.

Release 2.0 Enhancements (October 1992)
Refer to
Release 2.0 Notes
enhancements. Release 2.0 includes all Release 1.1 functionality
plus the enhancements listed below.
■ Programming
Programming enhancements include the following:
— Extension Copy is a feature that reduces programming time
by allowing the use of any extension as a template for
programming another extension or block of extensions
through ce ntralized telephone programming.
— Integrate d Administration provides a single interface through
Integrated Solution III (IS III) for programming entries
common to the MERLIN LEGEND Communications System
and AUDIX™ Voice Power.
— Any SPM Version 2.xx (where xx is replaced by numbers)
provides a Convert function for use in upgrading the system
from Release 1.0 or 1.1. This function converts a backup file
from a Release 1.0 or 1.1 system to Release 2.0 and later
format, allowing reuse of existing system programming on
the upgraded system.
— Forced idle reductions keep system interruptions at a
minimum. In general, the smallest necessary component is
forced idle during programming activities. For example,
renumbering a single extension idles only one extension.
Only a few systemwide programming activities, such as
setting the system mode and system renumbering, idle the
entire system.
■ Operational
— System operational enhancements include the following:
— Coverage VMS Off is a feature that prevents incoming
outside calls from going to voice mail. (All other coverage
remains active as programmed.) The feature is programmed
extension by extension, either through extension
programming or through centralized telephone programming.
— A Night Service group can be programmed to include either
extensions or a calling group as members. You should not
program both individual extensions and a calling group into
the Night Service group, however, because individuals will
not have a chance to answer before calling group members
do.
— When AUDIX Voice Power sends a Leave Message
notification to an extension, the system identifies the voice
mail system as the sender of the message. When the voice
mail subscriber uses the Return Call feature, the call goes to
any available voice mail port, not just to the specific port that
generated the message. This reduces the chance of getting
a busy port.
— Coverage receivers can call coverage senders and have the
call receive coverage treatment. If a receiver calls a sender
for whom he o r she is covering, and the sender is busy or
unavailable, the call proceeds to other points of coverage. It
does not come back to the receiver who originated the call.

other multiline telephones, a Posted Message button must
be programmed for the Do Not Disturb message to be posted
automatically) when a user activates the Do Not Disturb
feature, and confirmation messages when a user activates
Hold, Privacy, Saved Number Dial, and Transfer.
— Direct Inward Dialing (DID) trunk emulation on a T1 facility
provides up to 24 DID channels on a single DS1 interface,
instead of requiring 24 separate physical trunks.
— A telephone user can send a timed flash (switchhook flash)
on a loop-start trunk call on a System Access (SA) button.
■ Fax Attendant Syste m ™
Fax Attendant is an application for s ending and receiving fa x
messages; its interface is similar to the voice mail interface
provided by AUDIX Voice Power. Fax Attendant System, which
co-resides with AUDIX Voice Power on the IS III platform,
provides the following services:
— Fax Call Coverage. Receives and holds messages for
subscribers whose fax machines are busy or out of paper.
This service also allows a subscriber to have a personal fax
number without having a fax machine.
— Fax Mail.Allows subscribers to create and use fax
distribution lists, send and receive fax messages, and record
personal greetings for incoming fax calls.

Design Benefits
■ SPM
SPM enhancements include operation in English, French, or
Spanish, faster backup and restore, and automatic onscreen
display of reports as they are created, with a Browse capability
for reading the reports.
■ Equipment
Additional equipment includes the 8102 and 8110 analog
telephones, four headsets, two headset amplifiers, and a
transparent protective cover for the MLX-10 and MLX-10D
telephones. The 8102 and 8110 telephones are also compatible
with Release 1.0.
■ PF Registration
PF registration number AS5USA-65646-PF-E is assigned by
the FCC for operating the MERLIN LEGEND Communications
System in Hybrid/PBX mode in the United States. (The PF
registration is also applicable to Release 1.0 systems.)
Design Benefits
Modular component s allow easy, cost-effective growth in both size
and function. For upgrades from the MERLIN LEGEND
Communications System, all wiring and analog MERLIN System
telephones can be reused. For upgrades from the MERLIN II
Communications System, certain trunk and extension modules can
also be reused. The modules are 800, 400 (LS), 400EM, 012 T/R,
008, and 408.
Menu-driven system programming maintains the customer’s
command of business operations.
Built-in 1200/2400-bps modem allows fast access to the system
by customers, Lucent Technologies personnel, or authorized
dealers from a remote location for system programming and
maintenance.
Flexible mode of operation saves upgrade costs by allowing
system configuration in one of three modes: Hybrid/PBX, Key, and
Behind Switch. (The factory setting on the 3.0 process or board is
Hybrid/PBX.)
Connectivity to other systems in the Behind Switch mode
optimizes existing resources by allowing the system to work as part
of another MERLIN LEGEND Communications System, System 25,
System 75, System 85, DEFINITY 75/85, or other communications
system. The control unit can connect to another system’s control
unit via either an off-premises telephone (OPT) line or an analog or
digital tie trunk.
Digital 2.048-MHz bus supplies a 64-kbps channel on each of the
216 time slots.
68EC020 Motorola CPU running at 16 MHz with zero wait states
provides fast system performance.
Memory data retention saves time by ensuring that system and
extension programming information is retained for five (5) days,
depending on the system configuration, in case of power failure or
system shutdown.
Integrated voice and data capabilities allow users to talk while
transmitting data at speeds up to 64 kbps.

Power and Grounding
■ Do not place anything on top of carriers.
■ Do not install the control unit under any device that may drip
fluid, such as an air conditioner.
■ Do not expose the control unit to moisture, corrosive gases,
dust, chemicals, spray paint, or similar materials.
Power and Grounding
Proper power and grounding are essential for correct and safe
functioning of the system.
Power Specifications
The system control unit plugs into a 117-V AC outlet. To avoid
accidental disconnection of the system, this outlet should not be
controlled by a wall switch.
Each carrier unit requires its own power supply. Each power supply
requires a maximum current of 5.4 amps. Therefore, if expansion
carrier units are added to the system, extra AC outlets may be
needed.
Grounding Requirements
Proper grounding of the installation site protects the system against
the following:
— Lightning
— Power surges
— Power crosses on outside lines/trunks
— Electrostatic discharge (ESD)
The local telephone company is responsible for providing protection
of outside lines/trunks at the entrance to the site. The protection
should consist of the following:
— Carbon blocks or gas discharge tubes connected to an
approved ground
— Adequate bonding of the outside line/trunk protector ground
and the power company ground
WARNING:
!
An improper ground can result in equipment failures and
service outages. Verify that the AC power uses an approved
ground for its primary ground, that all voltage-limiting devices
are grounded to an approved ground, and that the ground is
one of the approved grounds listed below.
Issue 1
April 1999
35
The following is a list of approved grounds, starting with the most
preferred:
— Building steel.
— Acceptable water pipe, must be a metal, underground water
pipe at least 1/2-inch (30.4 cm) in diameter, and in direct
contact with the earth for at least 10 feet (3 m).
— It must be electrically continuous so that the protector ground
is connected. (Check for insulated joints, plastic pipe, and
plastic water meters that might interrupt electrical continuity.)
MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Power and Grounding
— A metallic underground water pipe must be supplemented by
the metal frame of the building, a concrete-encased ground,
or a ground ring.
— Other local metal underground systems or local underground
structures such as tanks and piping systems.
— Rod and pipe electrodes, a 5/8-i nch (1. 6-c m) sol id rod or
3/4-inch (1.9-cm) conduit or pipe electrode driven to a
minimum depth of 8 feet (244 cm).
— Plate electrode, a minimum of 2 square feet (61 square cm)
of metallic surface exposed to the exterior soil.
— Concrete-encased ground, which must be an electrode,
consisting of one of the following:
— At least 20 feet (6.1 m) of one or more steel reinforcing
rods, each being at least 1/2-inch (1.27 cm) in diameter.
— 20 feet (6.1 m) of bare copper conductor not smaller than
#4 AWG, encased in 2 inches (5 cm) of concrete. This
electrode must be located within and near the bottom of a
concrete foundation or roofing that is in direct contact with
the earth.
— Ground ring, consisting of at least 20 feet (6.1 m) of bare
copper conductor not smaller than #2 AWG, encircling the
building. The ground ring must be in direct contact with the
earth and buried at least 2.5 feet (77 cm) below the earth’s
surface.
WARNING:
!
Do not use a metal underground gas piping system. This is a
safety risk.

For most power surges, the following standard grounding
requirements provide adequate lightning and surge protection:
— Properly wired/grounded/bonded outside line protectors
— Properly wired/grounded AC outlet
— Properly grounded single-point ground bar
— Properly wired connection between single-point ground and
power supplies
Additional Power Surge Protection
The 391C1, 391A3, 391A2, and 391A1 power supplies have built-in
AC line protection. This built-in protection handles almost all
situations.
Occasionally, additional protection may be needed if the customer is
located in a heavy lightning area. The following products are
available:
— The 147A protector provides AC surge protection for
In-Range Out-of-Building (IROB) extensions. This protector
can also provide surge protection for the 391A power supply
module in heavy lightning areas.
MERLIN LEGEND Communications System Release 7.0
Pocket Reference
555-670-116
Control Unit Interfaces
— The 145D protector provides AC surge protection for the
entire system, including the power supply module. One unit
provides protection for six outlets.
— The 146C protector provides Central Office (CO) line surge
protection. One unit covers four CO lines.
Complete installation instructions are provided with the surge
protectors.

Hardware and Software Capacities
Hardware and Software Capacities
You can configure the system as a stand-alone unit or as part of a
private network. Maximum system capacities are as follows:
— Up to 108 simultaneo u s two-par ty conversations
NOTE:
If more than 108 conversations are in progress at the same
time, blocking can occur.
— Up to 80 line/trunk jacks, including loop-start, ground-start,
DID, tie, and DSI
— Up to 400 extension endpoints that support a combination of
the following:
— Up to 272 physical extension jacks for telephones and
adjuncts
— Up to 200 logical digital data ports (through ISDN terminal
adapters connected to jacks on the MLX module)
providing RS-232 connections to data terminals and
personal computers
— System call-handling capability of 3828 hundred call seconds
per hour (ccs/hr)
— Up to three 100D DS1 modules, maximum two per carrier;
the 24 channels on each 100D DSI module count toward the
80 line/trunk capacity
— Up to five 800 NI-BRI modules, maximum two per carrier
(Release 4.0 and later)
— One CTI link when operating in Hybrid/PBX mode
The system has a total capacity of 352 physical jacks (80 outside
lines/trunks plus 272 extensions); however, each MLX module
extension jack supports two logical endpoints (extension devices
that can operate simultaneously and independently of each other).
For example, an MLX telephone with a Multi-Function Module
(MFM) plugs into one extension jack, but the jack supports both the
telephone and the equipment (for example, a fax or an analog
modem) connected to the MFM.
Similarly, although the 100D module has only one jack, it can serve
up to 24 endpoints (emulated lines/trunks or PRI lines/trunks). Thus,
you can configure the system to connect up to 80 lines/trunks and
400 extension endpoints—a total of 480 endpoints.
The next table, Hardware and Software Capacities, lists the
hardware and software capacities of the system. Constraining
Factors appear with a checkmark (✓) and are explained at the end
of the table.

dB loss1: 3dB (factory setting), 0dB if all calls are to another OPT station.
1 If one OPT station calls another OPT station, the loss values of th e two OPT
stations are added resulting in transmission level s that are too low.008 OP T
modules (517D28) may be hardware configured to 0dB loss, however this
should only be done if all or the majority of calls from the OPT stations are
to other OPT stations. Setting the loss value to 0dB violates EIA-464-A-1
specifications. Contact Tier 4 before modifying the l oss value settings of 008
OPT modules.

supply is used, or the ULs < 72 an d the
391A3 power supply is used, then no
calculation is required. If a 391A1 or
391A2 power supply is used and the

supply with a 391C1 power supply.
■ If ULs > 96, reconfigure the system so
that the total ULs does not exceed 96
