Your Responsibility for Your System’s Security
Toll fraud is the unauthorized use of your telecommunications system by an unauthorized party, for example, persons other than your company’s employees, agents, subcontractors, or persons working on your company’s behalf. Note that there may be a risk of toll fraud associated with your telecommunications system, and if toll fraud occurs, it can result in subs tantial additional charges for you r tele com m unications services. You and your System Manager are responsible for the security of your system, such as programming and configuring your equipment to prevent unauthorized use. The System Manager is also responsible for reading all installation, instruction, and system programming documents provided with this product in order to fully understand the features th at ca n int roduce risk of toll fraud and the steps that can be taken to reduce that risk. Lucent Technologies does not warrant that this product is immune from or will prevent unauthorized use of common-carrier telecommunication services or facilities accessed through or connected to it. Lucent Technologies will not be responsible for any charges that result from such unau­thorized use.

Centralized Voice Messaging 0
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 hub. This sharing of
the VMS is called “Centralized Voice Messaging.” Centralized Voice Messaging includes the functions of voice mail, Automated Attendant, and fax messaging. See the
Network Reference
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 VMS’s is more economical.
Users that travel between sites can dial the same digits anywhere in the
private 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.

Page xivRelease 6.1 Enhancements (August, 1998)
Productivity is enhanced because messages can be forwarded and
broadcasted 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 efficiency saves time because a user only has to look at his or her telephone to determine if he or she has a message.
Group Calling Enhancements 0
A calling group can have a Dial Plan and exists on another MERLIN LEGEND Communications System connected by a tandem trunk to the local system. If a calling group contains a non-local member, the non-local member must be the group. See the
Network Reference
A calling group containing a single non-local member can be used for the same purposes as a calling group containing local extensions, including:
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.

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 0
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 Selector 0
Issue 1
August 1998
Page xvRelease 6.1 Enhancements (August, 1998)
Now users can press a Direct Station Selector (DSS) button for a non-local extension to make or transfer calls to that extension. However, no busy indication is displayed by the DSS for non-local extensions.
Call Forwarding 0
The Forward feature now can be used to send calls to non-local extensions across the private network.
SMDR 0
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 Set-Up Time 0
The set-up time for a call across a private network has been reduced by programming the number of UDP digits expected.
MERLIN LEGENDCommunications System Release 6.1 System Planning
New Features and Enhancements
555-661-112
PRI Switch Type Test 0
A new maintenance test, the PRI Switch Type Test, has been created to allow Lucent T echnologies technicians or authorized dealers to automatically determine if each end of the PRI tandem trunks has been programmed correctly.

Service Observing 0

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 observing how a Customer Service representative handles calls.
The Service Observing group can consist of 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.
Issue 1
August 1998
Page xviRelease 6.1 Enhancements (August, 1998)
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.
Win SPM 0
The System Programming and Maintenance (SPM) software is now available in a Windows format called

Win SPM

. For Release 6.1 and later systems, Win SPM provides a graphical user interface (GUI) for those tasks must commonly performed by the system manager. Pictorial representations of system components, such as modules and their vintages and the creation of MLX telephone button labels, appear on Win SPM. Win SPM also provides a DOS-emulator mode to program tasks not currently supported by the GUI and to program a MERLIN LEGEND system of Release 6.0 or earlier. Win SPM is available on CD-ROM and is supported in Windows 95, Windows NT, and Windows 98.

Windows NT Driver 0

Now available is the MERLIN LEGEND Windows NT PBX driver. When coupled with the CentreVu Telephony Services application, the driver provides true server-based Computer Telephony Integration (CTI). The new driver requires a MERLIN LEGEND system of Release 5.0 or later and servers and PCs that support the applications.

Private Networks 0

In Hybrid/PBX mode systems only, MERLIN LEGEND Communications Systems can be networked with one another or with DEFINITY Communications Server (ECS) and ProLogix 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 as many as 20 patterns,

associates with 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 telephone for incoming calls across PRI tandem trunks.
Toll Savings. Pri vat e net wor ked tr un ks may al low yo u to real iz e si gnifi cant
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 (Boston) can do so through a line/trunk connected to the system in Boston. For example, he or she might dial ,
. The local ARS tables would route this
call over the private network 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 saving, there are two ways
that organizations can save on service costs incurred from telecommunications providers that provide public switched telephone network access:
— You 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 64kbps per channel or 128 kbps for 2B data, while keeping the remaining B-channels for PRI voice traffic. The PRI D-channel must remain active.
— You 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-and-insert equipment to provide fractional T1 use.

Voice Mail and Auto Attendant. Networked systems should have their
own local voice mail and/or auto attendant applications as well as their own external alerts and Music On Hold sources. However, a single auto attendant 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.
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 0

Release 6.0 and later systems include Group Calling features that enhance group calling operations.
Queue Control 0
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.
Issue 1
August 1998

Queue control applies to calls received on the following types of facilities:
DID (Direct Inward Dialing)
PRI facilities programmed for dial-plan routing
All calls transferred from a VMI (voice messaging interface) port
Dial-in Tie
Queue control also applies to internal calls to a DGC group and calls to a calling group through the QCC.
Internal calls that dial  or  and are directed to a calling group administered as Position-Busy Backup are eligible for queue control. Calls that come in on a trunk assigned to the Queued Call Console (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 calling group through QCC Position-Busy backup, and all other outside calls are not eligible for queue control.

Prompt-Based Overflow 0
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 0

Issue 1
August 1998
Page xxRelease 6.0 Enhancements (February, 1998)
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 Centrex 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 but 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 MERLIN 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 a
ll
loop-start lines in the system must be Centrex facilities. Loop-start lines do not have to provide reliable disconnect for use by the Centrex Transfer via Remote Call Forwarding feature.
To 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 and a Pause character may be required after the
instead of a dial-out code,
. The Centrex service provider
determines whether the Pause is needed.
MERLIN LEGENDCommunications System Release 6.1 System Planning
Prior Releases: Features and Enhancements
555-661-112
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 do apply, however.
Authorization Codes and Remote Call Forwarding 0
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. This is especially useful for a single-line telephone user 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 (e.g. from another switch in the network). No other features can be used by entering an authorization code in this fashion.

Computer Telephony Integration (CTI) 0

Issue 1

Page xxiiRelease 5.0 Enhancements (June, 1997)
Beginning with Release 5.0, a PassageWay® Telephony Services CTI link from the MERLIN LEGEND Communications System to a LAN server running Novell
®
NetWare
software allows Lucent T echnologies-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.
NOTE:
The NetWare server software version must be 3.12, 4.1 or 4.11. The 008 MLX and 408 MLX modules must have firmware vintage other
than 29. If the module has firmware 29, programming a CTI link on the module is prevented. An earlier or later vi ntag e firmwar e is suppo r ted.
Basic Call Control 0
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 SA button
Making calls from an SA button
Hanging up calls
®
Hold 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.
MERLIN LEGENDCommunications System Release 6.1 System Planning

Screen Pop 0
Screen pop occurs when the calling number, called number, or other user-defined identifier (such as 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:
Calling group distribution
ISDN PRI Routing by Dial Plan
An extension on the MERLIN LEGEND Communications System
Remote access
Issue 1

Page xxiiiRelease 5.0 Enhancements (June, 1997)
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 DLC
or at a QCC
NOTES:
1. DLCs (Direct-Line Consoles) 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 not using a CTI link extension, it is
non-monitored
.
2. Calls to a QCC or non-monitored DLC do not initiate screen pop at the operator position, but 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.
3. Calls transferred from Cover buttons on non-monitored DLCs do not initiate screen pop at the destination extension.

HotLine Feature 0

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 connected to an 008 OPT, 012, or 016 module as a HotLine. When a user lifts the handset at the HotLine extens i on, the tele pho ne auto mati c all y dia ls 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.
Issue 1
August 1998
Page xxivRelease 5.0 Enhancements (June, 1997)
Any type of inside or outside line that is normally available to a single-line 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.
!
SECURITYlALERT:
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 0

Release 5.0 and later systems include Group Calling features that enhance group calling operations.
MERLIN LEGENDCommunications System Release 6.1 System Planning

Most Idle Hunt Type 0
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 applications, 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 0
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 Release 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.
Issue 1
August 1998
Page xxvRelease 5.0 Enhancements (June, 1997)
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 time (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 Group Calling Options in Chapter 4 for guidelines on setting the delay.)
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 administered as a secondary delay
announcement device.

Enhanced Calls-in-Queue Alarm Thresholds 0
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.
Issue 1
August 1998
Page xxviRelease 5.0 Enhancements (June,1997)
If the number of waiting calls is greater than or equal to the highest value,
Threshold 3, the LED lights steadily.
NOTE:
A DSS (Direct Station Selector) 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 programmed.
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 only signals when the number of calls in the queue meets or exceeds the programmed Threshold 3 value.

MLX-5 and MLX-5D Telephones 0

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 5 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 5-button telephones.
If these telephones are connected to communications system releases prior to

Improvements to Station Message Detail Recording (SMDR) and Support for MERLIN LEGEND Reporter Application 0

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 LEGEND Reporter features listed are administrable:
TALK Fiel d. 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 MERLIN LEGEND Communications System and not after a preset number of seconds. Call timing ends when the call is disconnected; either the caller or the agent hangs up. This allows the system manager to determine how long a caller

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.
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.

Single-Line Telephone Enhancements 0

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 CO. 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 other useless messages. This operation is not programmable.

Call Restriction Checking for Star Codes 0

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 (CO). For example, in many areas, a telephone user can dial  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.

Page xxxvRelease 3.1 Enhancements (March, 1996)

Trunk-to-Trunk Transfer Set for Each Extension 0

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 Dial Tone Timer 0

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 CO 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 CO 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 CO is ready to receive more digits from the caller.

Security Enhancements 0

The sections below outline security measures that are implemented in Release 3.1 and later systems.
Disallowed List Including Numbers Often Associated with Toll Fraud 0
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 VMI (voice messaging interface) ports used by voice messagi ng systems. The system manager ca n manual ly assign this list to other extensions.

Default Pool Dial-Out Code Restriction for All Extensions 0
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 0
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.

1. Review the system’s hardware, features, and operation as defined at the time of purchase.
2. Confirm the location of the control unit.
3. Obtain the required information from the local telephone company.
4. Obtain information about telephone users and their needs.
5. Obtain or develop a floor plan of the customers site.
Each of these preplanning tasks is described in this chapter.
Reviewing System Components 1
To tailor the system to the customer’s business, you must know the number and types of telephones, outside lines/trunks, and adjuncts that were ordered. You also need to know how the equipment will be used, for example, which type of telephone is assigned to each employee, which consoles operators will be using, and where adjuncts will be located.
Review the list of equipment ordered. If you did not participate in the ordering process, you may want to confer with the customer representative who did. You also may want to conduct a premises check to determine whether any additional equipment is required.

CAUTION:
The AC outlet for the control unit should not be switch-controlled. Plugging the control unit into an outlet that can be turned on and off by a switch can cause accidental disconnection of the system.
The AC outlet must be properly grounded by using an AC receptacle for a 3-prong plug.
Do not install the control unit outdoors. Do not place the control unit near extreme heat (furnaces, heaters,
attics, or direct sunlight). Do not expose the control unit to devices that generate electrical interference (such as arc welders or motors).

Do not expose the control unit to moisture, corrosive gases, dust, chemicals, spray paint, or similar material.
Do not place anything on top of the carriers. Do not install under any device that may drip fluid, such as an air
conditioner.
In addition, a backboard is needed to mount the system on the wall. One can be made locally from 0.75-in. (1.9-cm) plywood. The dimensions depend on the number of carriers, as shown in Table 1–2
light-weight plastic backboard may be ordered (COMCODE 847007523). In some areas, fire or electrical codes require a flame-retardant backboard. Check with the appropriate authorities to ensure that the proper material is provided. A template is available (COMCODE 847009206). It shows the layout for mounting equipment. It also comes with safety, electrical, environmental, and space requirements for the communications system.

Grounding Requirements 1

Proper grounding of the installation site is essential for correct and safe functioning of the system. Grounding protects the system against:
Lightning
Power su rges
Power crosses on outside lines/trunks
Electrostatic discharge (ESD)
The telephone company is responsible for providing protection of outside lines/trunks at the entrance to the site. The protection should consist of:
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
!
CAUTION:
Improper ground can result in equipment failures and service outages. Verify that the AC power uses an approved ground for its primary ground and that all voltage-limiting devices are attached to an approved ground. Approved grounds are as follows:
Issue 1
August 1998
Page 1-4Confirming the Location of the Control Unit
The metal frame of the building
A metal water pipe connected to an underground water pipe that is in direct contact with earth
An electrode encased by at least 2 inches (5 cm) of concrete and located within and near the bottom of a concrete foundation or footing in direct contact with earth
A copper ring that encircles a building and is in direct contact with earth
For most surge occurrences, the following standard grounding requirements provide adequate lightning and power surge protection:
Properly wired, grounded, and bonded outside line protectors
Properly wired and grounded AC outlet
Properly grounded single-point ground bar
Properly wired connection between single-point ground and power supply

Electrical Noise/Radio-Frequency Interference 1

In most cases, electrical noise is introduced to the system through lines/trunks or telephone cables. However, electromagnetic fields near the control unit may also induce noise in the system. Therefore, the control unit and cable runs should not be placed in areas where a high electromagnetic field strength exists. Radio transmitters (AM and FM), television stations, induction heaters, motors (with commutators) of 0.25 horsepower (200 watts) or greater, and similar equipment are leading causes of interference. Small tools with universal motors do not generally cause a problem when operated on separate power lines. Motors without commutators generally do not cause interference.
Field strengths below 1.0 volt per meter are unlikely to cause interference. Estimate the field strength produced by radio transmitters by dividing the square root of the emitted power (in kilowatts) by the distance from the antenna in kilometers.
This yields the approximate field strength in volts per meter and is relatively accurate for distances greater than about half a wavelength (492 feet, or 150 m, for a frequency of 1000 Hz).

To comply with FCC Part 15 requirements, each power supply on a newly installed system must have a ferrite core installed around the AC power cord and ground wire. Beginning with Release 2.1 this ferrite core is packaged with the power supply module at the factory. Ferrite cores are also compatible with earlier releases.

Obtaining User Information 1
The features and calling privileges you assign to each employee’s telephone ensure that employees get the most benefit from the system. If you were not involved in the planning and equipment-ordering for the system, you should discuss the system’s design with the customer representative who took part.
To determine calling privileges, answer the following questions:
Does management want to allow both local and toll calls to be made from
every telephone?
If any telephones are restricted, are there any numbers the users should be
allowed to call?
Are there any specific numbers (such as 900) that you want to restrict
users from calling?
Who, if anyone, will be given personal lines?
Will access to central office lines/trunks (outside lines) be restricted to
certain employees?

Page 1-11Obtaining User Information

Do any departments (such as sales and service) receive frequent special
calls that should come to them directly, bypassing a system operator?
Do any departments or extensions need to screen incoming calls?
You may want to use the Employee Communication Survey form to determine each employee’s telecommunications needs. A copy of this form is in Appendix B and is included in the forms package. Since a survey form should be completed for each user, make as many copies of the form as you need.
If it is not feasible for each employee fill out a form, get the information you need from a knowledgeable person in each department, section, or work group. This person should have sufficient information and authority to make decisions about calling features and coverage assignments for others in the department.
Use the information in Table 1–3
to interpret and analyze the results of the Employee Communication Survey. Numbers for items in the Required Information column correspond to question numbers on the survey.

Obtaining a Floor Plan 1
You may want to use a floor plan to make planning more manageable and to ensure that the correct telephone equipment is assigned to each employee. If the customer does not already have a floor plan showing the location of system equipment, you should create one. Use the symbols shown in Figure 1–2
following instructions:
1. Use a large sheet of paper and sketch the office layout. The location of office walls and other partitions is important when features are assigned to telephones that must be within hearing range of each other. For example, pickup group members must be able to hear each others’ telephones ringing.
2. Indicate the location of each employee’s telephone, other locations that will have a telephone (such as a conference room), and the locations of data terminals, PCs, and host computers.
3. Indicate the type of telephone at each location, using an abbreviation that includes the number of programmable buttons. For example, write at 10-button MLX telephones, telephones,
BIS-34 at 34-button analog multiline telephones, and so on.

1. Planning Module Placement. Calculate the system’s line/trunk and extension capacity according to the number of module types; then map out the placement of the modules on the Control Unit Diagram.
2. Recording System Operating Conditions. Note the system’s type of programming equipment, it’s mode and language choice, and whether the Automatic Maintenance Busy feature is to be enabled or disabled.
3. Numbering the System. Decide the order in which to connect the telephones and other equipment to the control unit based on the customer’s needs and applications. Determine whether the system-assigned extension numbers are appropriate for the customer’s business or if they need to be renumbered.
This chapter contains instructions for completing each of these tasks.

Planning Module Placement 2
In addition to the processor module and power supply module, the system supports several types of line/trunk and extension modules. Deciding how to place the modules in the carriers consists of the following tasks:
1. Calculating the system’s line/trunk capacity according to module types
2. Calculating the system’s extension capacity according to module types
3. Mapping out module placement on the Control Unit Diagram, according to specific guidelines
This section contains instructions for each of these tasks. For information about calculating unit load requirements, see Appendix F, “Unit
Load Calculation”. For detailed information about modules and their specifications (including
line/trunk and extension capacity), see the descriptions of hardware components contained in the

Line/trunk capacity is the number of lines/trunks that can be connected to the control unit. This section contains instructions for calculating the systems capacity for lines/trunks, according to the system’s module types.
Planning Form Instructions 2
1. In the table in the Line/Trunk Capacity section of Form 1, System Planning, fill in the number of each type of line/trunk module on the appropriate line of the Number of Modules column.
2. Add the column and record the result at the bottom of the column on the System Totals line.
3. For each module type noted, multiply the value in the Number of Modules column by the value in the Trunks Supported by Module column; write the results in the appropriate row under Total Trunks by Module Type.
4. Add the column and record the total line/trunk capacity of the system at the bottom of the column, on the System Totals line.

555-661-112

Capacity for Extensions 2

Extension capacity is the number of extensions that can be connected to the control unit. In most cases, the number of physical jacks on the modules indicates capacity. Most loop-start and ground-start modules have one or two power-failure transfer (PFT) jacks used to connect a single-line telephone in case of a power failure, and not counted in system capacity. Every four line jacks has one associated PFT jack.
One extension number is automatically assigned to each extension jack, whether or not equipment is connected to it, except for the 008 MLX, 408 GS/LS-MLX, and 008 OPT modules:
008 MLX and 408 GS/LS-MLX Modules. Two extension numbers are
assigned to each physical jack: the first for an MLX telephone and the second for any equipment connected to the telephone through an MFM, ISDN terminal adapter (such as the Ascend Pipeline 25 or 50), or any 2B data desktop video endpoint.
Issue 1

Page 2-3Planning Module Plac ement
NOTE:
When using the 008 MLX or 408 GS/LS-MLX module for data or video, you must use Version 28 of the module.
008 OPT Module. The system recognizes this module as an 012 module.
Therefore, even though the OPT module has only 8 physical jacks, it uses 12 ports of capacity . An extension number is assigned to each of the 8 physical jacks.
This section contains instructions for calculating the system’s extension capacity, according to the number of certain module types.
Planning Form Instructions 2
1. In the table under the Extension Capacity section of Form 1, fill in the number of each type of extension module on the appropriate line of the Number of Modules column.
Each 100D module is assigned 24 logical IDs, even though the
module has only 1 physical trunk jack.
Each 800 NI-BRI module is assigned 2 logical IDs per physical trunk
jack for a total of 16 logical IDs.
2. Add the column and record the result at the bottom of the column (System Totals line).
3. For each module, multiply the value in the Number of Modules column by the value in the Physical Jacks per Module column and record the results on the appropriate line in the Physical Jacks by Module Type column.
4. Add the column and record the results at the bottom of the column (System Totals).

555-661-112
5. To determine the number of extensions assigned for each module type, multiply the value in the Physical Jacks by Module Type column by the value in the Extensions Assigned column and write the results in the appropriate row in the Total Extensions Assigned column.
NOTE:
Since the system assigns an additional four extensions to each 008 OPT module, you must first calculate the Extensions Assigned by multiplying the number of 008 OPT modules (noted in the Number of Modules column) by 4 and then add this subtotal to the number noted in the Physical Jacks by Module Type column.
6. Add the column and record the result at the bottom of the column (System Totals).

Control Unit Diagram—Module Placement 2

This section describes how to use the Control Unit Diagram on Form 1 (page 2) to map the placement of the modules according to certain guidelines. Figure 2–1 on
page -6 provides an example of a Control Unit Diagram for a system with 32
lines/trunks and 52 extensions. In addition, this section describes how to identify each jack on each module with respect to type (line/trunk or extension) and its associated logical ID. Each physical jack on the control unit is numbered sequentially from bottom to top and left to right with logical IDs as follows:
Issue 1
August 1998
Page 2-4Planning Module Plac ement
Extension jacks are numbered from 1 to 200.
Line/trunk jacks are numbered from 1 to 80.
This sequence of logical IDs is the basis for connecting components to the control unit, as well as for the assignment of extension numbers and line/trunk numbers.

1. On the Control Unit Diagram of Form 1 (page 2), record the type of module to be installed in each slot by writing the module name (for example,
008 MLX) on the slanted lines at the top of each slot. Use the following
guidelines:
Indicate the power supply module in the far left slot of each carrier.
Indicate the processor module in Slot 00 of the basic carrier.
Indicate line/trunk and extension modules in any order in Slots 01
through 17, with the following conditions:
— Group the modules in each carrier from left to right with no
empty slots between modules. (The system does not recognize modules in slots that follow an empty slot; slots to the right of the last module can be left empty.)
— (Hybrid/PBX mode only) If the system includes a Queued
Call Console (QCC), the first line/trunk and/or extension module must be a 408 GS/LS-MLX or 008 MLX module.
— (All modes) Current 012 T/R, 008 OPT , and 016 T/R modules
have built-in ring generators and are compatible with earlier releases. The 012 T/R module [517J13 (28)] has a ring equivalency number (REN) of 2.2 and rings only four ports at a time, although eight jacks can be used for applications. The 016 T/R module (517C34) has a REN of 4, can ring 16 ports at a time, and has no restriction on the number of jacks that can be used for applications.

— Group all 800 DID, 100D, 800 NI-BRI, and 400EM modules
together according to type; this helps save time in system programming.
NOTES:
1. Due to limitations in the 391A, 391A1, and 391A2 power supplies, the number of 800 NI-BRI modules plu s 100D modu le s in a single carr i er cannot exceed three. If you have more than three modules, you must install the additional modules in an expansion carrier. This restriction does not apply to the 391C1 or 391A3 power supply.
2. In Release 6.0 or later, if the switch is part of a private network and a tandem PRI trunk (programmed as Legend-PBX or Legend-NTWK) has some B-channels that would bring the total number of trunks over the system limit of 80, the 100D module for that tandem PRI trunk should be placed in the last slot in the carrier. In this manner, the 100D module will contain the last lines in the system, and any B-channel over the 80 line/trunk limit will be ignored. However, the D-channel will still function even if the 100D module exceeds the line capacity of the system. The number of B-channels must be the same on each networked system. See

You fill in the extension number of the jack later.

System Mode 2

The mode of operation determines how outside lines/trunks are provided to users, the types of operator consoles allowed, the features available, and how they work. Each system is registered with the Federal Communications Commission (FCC) to operate as a Private Branch Exchange (PBX), Hybrid, or Key system (factory setting). However, you can program the system to operate in any of the three modes: Hybrid/PBX, Key, or Behind Switch.
Planning Form Instructions 2
Under the System Mode heading in the System Operating Conditions section of
one
Form 1 (page 2), check
of the following:
If the system will operate in Key mode, check Key. (This is the factory
setting.) If need be, this mode can be changed to Hybrid/PBX mode at another time.
If the system will operate in Hybrid/PBX mode, check Hybrid/PBX.
If the system will be connected behind a larger system or a Centrex
system, check Behind Switch and record the host’s dial codes for the Transfer, Conference, and Drop features so users can access these features on the larger system.
If you check Permanent Key, the switch in the back of the processor
module must be placed in the Permanent Key position. The switch cannot be changed without changing the FCC registration of the system.

Second Dial Tone Timer 2

In some instances, after dialing a star code the CO responds with a second dial tone as a prompt to enter additional digits. Once a star code is accepted by the communications system, the Second Dial Tone Timer is activated and set to the programmed value. If dialing is attempted before the Second Dial Tone Timer expires, the call is treated as though it had violated calling restrictions and is not completed.
!
SecurityAlert:
If the Second Dial Tone Timer is set to 0 ms and a caller begins dialing additional digits before the second dial tone, system restrictions may be bypassed and a restricted call may be routed. Careful administration of the Second Dial Tone Timer prevents the caller from bypassing call restrictions in this manner.
Marked System Speed Dial entries (entries that do not display) are not affected by the Second Dial Tone Timer setting. If the Central Office does not immediately supply dial tone when a star code is entered and a Marked System Speed Dial entry uses st ar codes, th en th e ap prop ria te n umb er of pa uses (eac h 1. 5 se cond s) must be programmed in the entry following each star code.

Numbering the System 2
This section describes the assignment of numbers to extensions.
NOTE:NOTE:NOTE:
Assigning numbers to calling groups, paging groups, park zones, and remote access is described later in this book.
The process of numbering extensions consists of the following tasks:
Identifying Extension Jacks. Using the placement of modules in the
control unit as a guide (see the Control Unit Diagram on Form 1), determine the order in which to connect telephones and other equipment to the control unit. To do this, identify the extension jack types available by module and then match system components (for example, operator positions or telephone types) with the jacks that support them.
Renumbering. If the system-assigned extension numbers are not
appropriate for the customer’s business, change them. The system offers two automatic numbering plans (2-digit and 3-digit numbers), as well as the option of creating a unique numbering plan with extension numbers of 1 to 4 digits. Each of these three plans allows renumbering of all or selected extensions.

Identifying extension jacks consists of the following tasks:
Determining which extension jack types are available according to the
types of modules in the control unit.
Matching the telephones and other equipment to the jacks that support
them, in the following order:
— Primary operator position — A dd iti ona l oper ato r posit ion s — CTI link port — Extension jack pairs (for analog multiline telephones only with Voice
Announce to Busy feature and/or voice and data) — MLX telephones — Analog multiline telephones — Tip/ring equipment and applications

Planning Form Instructions 2
Refer to the completed Control Unit Diagram (Form 1) and Table 2–1 above to
mark the extension jack types on Fo rm 2a:
1. For each extension module noted in the Control Unit Diagram (beginning with Slot 01), write in the type of module in the Mod. Type column of Form 2a and, after the appropriate logical ID (Log. ID) number, draw a line to indicate the end of that module.
For example, if the first module in the control unit is an 008 MLX module that has eight jacks, write 008 MLX in the Mod. Type column and draw a line after Logical ID 8.
NOTE:
If your list includes an 008 OPT module, draw a line after the twelfth logical ID, but cross off the last four logical IDs, since these jacks cannot be used to physically connect telephone equipment. The extension numbers of these logical IDs can be used, however, for applications requiring phantom extensions.
2. In the Jack Type column of Form 2a, do type of each extension jack next to its logical ID:

You are now ready to match the system telephones and other equipment to these available jacks. After calculating touch-tone receivers as described in the next section, begin matching equipment and jacks with Jack for Primary Operator Position, and proceed through the subsequent sections as appropriate for the system.
Touch-Tone Receivers (TTRs) 2
Use these guidelines for calculating the system requirements for touch-tone receivers for systems both with and without a voice messaging system (VMS).
The number of TTRs needed in a MERLIN LEGEND system should be calculated before the system is installed so that you can order the modules required to supply the TTRs. However, as the volume of calls increases and more applications are added to the system, TTRs may also need to be added. A system that exhibits one or more of the following symptoms may need more TTRs:
Single-line telephone users do not get dial tone when they lift the handset
to dial out.
The voice messaging system fails to transfer calls.
Calls fail to ring or go to coverage prematurely.
Reorder tone on UDP/ARS calls using tandem tie trunks.
Delay in MWL tie trunks when tie trunks are available.

A voice messaging system (VMS) requires a certain number of TTRs in addition to any system requirements for TTRs. The number of TTRs depends on the number of ports used by the voice messaging system (see Table 2–3
). TTRs are
also required in private networks using E&M, T1 tie, and tandem tie trunks.

Table 2–4 estimates the total number of TTRs required in the system, based on
call volume and whether the system uses account codes. The call volume per hour in this table includes all calls originating from single-line telephones, calls on tie lines, incoming remote access and Direct Inward Dial (DID) calls.
NOTE:NOTE:NOTE:
You must consider the call traffic across a private network when estimating the number of required TTRs. This includes calls on analog tandem tie trunks and T1-emulated tandem tie trunks. In addition, if your private network includes Centralized Voice Messaging, you must consider the call traffic coming across the private network for the voice messaging system and the TTRs required for the updating of Message Waiting lights (Release 6.1 or later systems). For this updating, a TTR is required at the sending end and the receiving end. If the systems in the private network are connected by PRI trunks, no additional TTRs are needed.

August 1998
Page 2-20Numbering the System
1. If the system has a VMS, use Table 2–3
to find the number of TTRs
required by the system to support the VMS.
2. Estimate the hourly call volume for all calls originating from single-line telephones, incoming calls (including private network tandem tie trunks) on Remote Access and DID lines, all calls on tie lines, and calls routed to the VMS. Use Table 2–4
to find the system requirements for TTRs based on
the estimated hourly call volume, and whether Account Codes are used.
NOTE:
You must consider the call traffic across a private network when estimating the number of required TTRs. This includes calls on analog tandem tie trunks and T1-emu lat ed tande m tie tru nks. In addition, if your private network includes Centralized Voice Messaging, you must consider the call traffic coming across the private network for the voice messaging system and the TTRs required for the updating of Message Waiting lights (Release 6.1 or later systems). For this updating, a TTR is required at the sending end and the receiving end. If the systems in the private network are connected by PRI trunks, no additional TTRs are needed.
3. Add the number of TTRs obtained in Step 1
and Step 2. If the Group Calling Prompt-Based Overflow setting (Release 6.0 and later systems) is not being used, go to Step 6
.
4. If the Group Calling Prompt-Based Overflow feature is being used, add the number of TTRs needed for the primary delay announcement devices that are assigned to those calling groups. Use Table 2–5
to determine the TTR
requirements for the primary delay announcement devices.
5. If applicable, add the number of TTRs needed for the secondary delay announcement devices that are assigned to calling groups using the Prompt-Based Overflow feature. Use Table 2–6
to determine the TTR
requirements for the secondary delay announcement devices.
NOTE:
If no announcement is used on a primary or secondary delay announcement device, no TTRs are needed.
6. Use Table 2–2
for information on the number of TTRs provided by each
type of module, and to determine the number of TTRs already supplied.
7. Compare the total TTRs needed to the total TTRs already supplied to determine if additional TTRs are required.
8. Add a new module if more TTRs are required.

NOTE:NOTE:NOTE:
When using the 008 MLX or 408 GS/LS-MLX module for data, video, or as a CTI link, you must use Version 28 of the module.
The system assigns two extensions, although only one logical ID is assigned to each digital extension jack. For MLX telephones, one extension number is automatically assigned to the MLX telephone physically connected to the digital extension jack. The second extension number is reserved for an adjunct, such as an analog modem or Delay Announcement Device, that can be connected to the MLX telephone through a Multi-Function Module (MFM). For information about renumbering jacks, see “System Renumbering” later in this chapter.
Issue 1
August 1998
Page 2-25Numbering the System
The system automatically assigns both extension numbers whether or not the extension includes an MFM or ISDN terminal adapter. Calls can be placed to both extension numbers independently.
The MFM can operate as an interface for either a Supplemental Alert Adapter or a tip/ring device. The Supplemental Alert Adapter (SAA) setting on the MFM is used when the MFM connects an external alert such as a bell or horn. The tip/ring (T/R) setting is used when the MFM connects a tip/ring device such as an answering machine or an analog modem.
NOTES:
1. The system capacity for endpoints is decreased by two whenever an MLX telephone is used.
2. In Behind Switch mode, the system automatically assigns two prime lines to each port on an MLX module — one for the MLX telephone and one for the device connected to the MFM. If an MFM is not connected to an MLX telephone or the MLX port is not used, the prime line for the MFM can be removed. The prime line can then be assigned to another user.
When PRI, NI-1 BRI, or T1 Switched 56 lines/trunks are assigned to an MLX jack, digital data/video stations may use two B-channels simultaneously (2B Data) to place or receive high-speed data/video calls.

The CTI link allows the computer users to interact directly with the communications system and obtain access to features through the use of a computer. Once installation is completed, the CTI port does not need feature programming, but the port and extension information must be recorded to be used when programming the network features.
If an MLX or analog multiline telephone extension is going to have a CTI-capable program installed on the extension’s worktop PC, then you need to identify both the CTI link extension (the MLX port extension that connects to the CTI Server), and the MLX or analog multiline telephone extensions that will have the CTI-capable program installed. Single-line telephones cannot make use of CTI.
If the CTI link is on the first MLX module in the system, then perform administration for the CTI link using SPM. If the CTI link is not on the first MLX module, then you can use the system programming console to do the programming.
CTI can be used only on Release 5.0 and later communications systems in Hybrid/PBX mode.
To get the Incoming Caller ID (ICLID) information, LS-ID delay must be set to On (factory setting is Off).
To use a CTI application for Call Control features (Hold, Hold retrieve, Consult, Transfer, or Conference), the call must be on an SA button.

Extensions that interact with a CTI-capable program on a computer (extensions marked Computer Telephony Integrated Client PC) should not have Microphone Disable programmed.
The CTI link must be connected to an extension that is on an MLX port module (008 MLX or 408 MLX). However, the extension cannot be on a module of firmware vintage 29, the console programming port, or a potential operator position in the first or fifth port on the module. CTI link programming removes 2B Data programming for a port. If you want to keep a port programmed as a

Jacks for Tip/Ring Equipment and Applications 2
Use these instructions only if the system includes 012 T/R, 016 T/R, or 008 OPT
modules. Otherwise, skip to the next section, “Labels”. Assign the basic telephone jacks on the 012 T/R, 016 T/R, or 008 OPT modules to
any tip/ring equipment such as single-line telephones, fax machines, analog modems, or Group Calling Delay Announcement Devices. The hardware design of the 008 OPT module includes an interface for off-premises telephones, which supplies increased gain levels and protection.
If assigning basic telephone jacks on an 016 T/R module, the Ringing Frequency may be set to either 20-Hz (Type A) or 25-Hz (Type E). The Ringing Frequency is programmable on each 016 T/R module and affects all ports on that module.
Several optional applications, if used with the system, require basic jacks on a 012 T/R or 016 T/R module: Enhanced Service Center, Messaging 2000, Intuity AUDIX, Lucent Technologies Attendant Solution II (IS II)* or III (IS III)*, and Integrated Voice Power Automated Attendant-IS II* or IS III*. Do not use the 008 OPT module for these applications.

NOTES:
1. Older versions of the 012 T/R module, (apparatus codes 517C13–517F13) if one or more applications are used, only four tip/ring devices may be assigned to the module where the application is assigned, regardless of how many jacks are open.
2. The application s in Table 2–8
do not work properly with 012 T/R modules manufactured for older MERLIN II systems. These applications must be connected to 016 T/R modules or 012 T/R modules with code 517C13 or higher labeled on the top of the module. Modules with code 517A13 or 517B13 can be used to connect single-line telephones only. They do not provide the disconnect signal required by answering machines and applications. Do not use the 008 OPT module for applications such as Enhanced Service Center, Messaging 2000, or Intuity AUDIX.
3. When planning for CONVERSANT, refer to the documentation provided with the application and contact the SDSC (1 888 297-4700 and follow the prompts to reach the CONVERSANT split) for information on TTRs and ports.

System Renumbering 2

The selection of a numbering plan depends on the customer’s needs. Each of the systems numbering plans (2-digit, 3-digit, and Set Up Space) allows you to renumber all or selected extensions. If you do not need to renumber extensions, skip to the last section of this chapter, “Updating Planning Information”.
Issue 1
August 1998
Page 2-33Numbering the System
In Release 6.0 and later systems (Hybrid/PBX mode only), the Uniform Dial Plan (UDP) allows you to choose non-local dial plan numbering to specify the numbering of extensions connected to remote systems in a private network and allow users on your system to access those extensions as if they were connected to your own system. When renumbering a system that is part of a private network, see the Network Reference for informat ion.

CAUTION:
CAUTION:
Before programming the private network ranges, set up the local dial plan. If the ranges are programmed in the network, and then 2-digit, 3-digit, or Set Up Space factory settings are used, all network ranges on that switch are erased.
Before the system is renumbered, the AUDIX Voice Power channel assignments should be deleted (through AUDIX Voice Power) for the extensions being renumbered. When the renumbering for the system is complete, AUDIX Voice Power channels for the renumbered extensions should be added.
Figure 2–2 through Figure 2–4 list the extension numbers according to the three
numbering plans: 2-digit, 3-digit, and Set Up Space. The numbers are arranged in blocks according to the first digit. The type of equipment or feature they are assigned is shown in the block. The shaded areas of the table indicate extension numbers automatically assigned by the system. The unshaded areas indicate the extension numbers available for reassignment. Use the appropriate plan-specific instructions that follow to mark Forms 2a and 2b with extension number assign­ments.

3. The MERLIN LEGEND Communications System does not support timed switchhook flash with NI-1 BRI lines. Pressing the Recall button on a MERLIN LEGEND telephone will be ignored. If the Recall button is stored as part of an Auto Dial string, it will not be sent out over an NI-1 BRI line, or stored for Last Number Dial or Saved Number Dial when calling on an NI-1 BRI line.
4. The MERLIN LEGEND Communications System does not support BRI features such as Local Area Signaling Services (LASS), CO Transfer, and other Centrex offerings.
5. Trunks used for incoming caller line identification (ICLID) service should not have any equipment other than the MERLIN LEGEND line port connected to them. Connecting other equipment (such as alarms, autodialers, and so on) may result in distorted or lost ICLID data.
6. Trunks assigned as either the system Music on Hold or External Page Port cannot be assigned as a Group Calling trunk.
LS-ID Delay Option 3
Issue 1
August 1998
Page 3-4Identifying Line/Trunk Jacks
The LS-ID Delay option is available through the 800 GS/LS-ID module and is programmed for each trunk. It prevents applications and adjuncts from answering before the Caller ID information is processed.
Use the LS-ID Delay option only if the following conditions apply:
If the adjunct or application cannot be programmed to answer on the
second or later ring, see the documentation for the adjunct or application.
If the first option applies (as with headsets using Auto Answer All) and line
buttons receiving Caller ID cannot be programmed for Delay Ring, for example, auto attendants.
NOTES:
1. It is recommended that trunks with the LS-ID Delay option be used as incoming trunks only.
2. If no delay is programmed, the caller may hear one or two extra bursts of ringback while the person receiving the call has not yet heard a ring.
3. If the option is programmed on a two-way trunk, the system will not seize a trunk from the pool for an outgoing call when that trunk is receiving an incoming call.
4. Use the LS-ID Delay option if the adjunct or application does not allow line buttons to be set for Delay Ring.
5. If the option is programmed on a trunk programmed as a Group Calling trunk, the system will not dispense the call to either the Group Calling queue or to any calling group member until either the LS-ID Delay timer expires or the system software is informed that ICLID information is unavailable.

Refer to the completed Control Unit Diagram on Form 1 to mark line/trunk jack types on Form 2c:
1. For each module with line/trunk jacks noted in the Control Unit Diagram (beginning with Slot 01), write in the type of module and its slot number in the Module Type and Slot No. column of Form 2c; after the appropriate Log. ID number, draw a line to indicate the logical IDs (and therefore, the line/trunk jacks) that correspond to that module.
If the system has 100D (DS1) modules, keep in mind that even though the module has only one physical jack, the 100D module supports up to 24 endpoints. Therefore, 24 logical IDs and associated line/trunk numbers are assigned to each module.
The 800 NI-BRI module supports up to 16 endpoints, therefore 16 logical IDs and associated line/trunk numbers are assigned to each 800 NI-BRI module even though the module has only eight physical jacks.
2. In the Jack Type column of Form 2c, for all modules except 100D modules, write the jack type for each logical ID. Use the codes shown in Table 3–2

NOTE:NOTE:NOTE:
(Key mode only) If the system is registered with the FCC registration number of AS59CM-7914-KF-E, and the processor module has been modified for Permanent Key mode, you can connect loop-start trunks to the GS/LS type line/trunk jacks. With the KF registration number, ground-start trunks are allowed only when the system includes DS1 connectivity dedicated as a T1 type and the channels are used to emulate ground-start trunks.
This procedure also includes instructions for assigning a label to identify the line/trunk being used.

Page 3-6Identifying Line/Trunk Jacks
1. In the Incoming Line/Trunk Type column of Form 2c, write the type of line/trunk you plan to connect to each line/trunk jack, T1 channel or BRI channel: Main No., personal line, FX (Foreign Exchange), WATS (include band), DID, or Tie. (Contact the local telephone company for line/trunk information.) Use the following guidelines:
Group trunks together according to type: basic loop-start or
ground-start trunks, and special-purpose loop-start or ground-start trunks. (DID, PRI, T1, BRI and tie trunks are automatically grouped according to type since they require specific types of modules.) The local telephone company supplies the information you need to identify the specific trunks connected to each line/trunk jack on each DID and tie trunk module and each channel on each 100D or 800 NI-BRI module.
Use line/trunk jacks at the beginning of the sequence for basic
ground-start and/or basic loop-start trunks. Use jacks later in the sequence for special-purpose trunks such as WATS or FX.
If a line/trunk such as WATS is only inbound or only outbound (not
two-way), include that information along with the line/trunk type.
