Release 6.0 Enhancements 0

Issue 1

February 1998

Page xviiRelease 6.0 Enhancements

Release 6.0 includes all Release 5.0 functionality, plus the enhancements listed
below.

Private Networks 0

In Hybrid/ PBX mode systems only, MERLIN LEGEND Communi ca tions 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, del ay-start t ie trunks or T1 trunks administered
as PRI can act as

tandem trunks

to connect networked systems.

Available for Hybrid/PBX mode systems, the private network features of the
MERLIN LEGEND Communications Syste m 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 extens ion
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. 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 (Boston) can do so through a
line/trunk connected to the system in Boston. For example, he or
she might dial,



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.

Issue 1

February 1998

Page xviiiRelease 6.0 Enhancements

. The local ARS tables would route this

— 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 s av in gs .

■ 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 switc hed telephone
network access:

— You order a point to point T1 facility from a service provider, then

use syste m programmin g to set it up for PR I sig nalling. A s
necessary, a service provider can provide amplification on the T1
facility, but does not su p ply switching serv ic es .

— 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.

MERLIN LEGEND Communications System Release 6.0

System Manager’s Guide

New Features and Enhancements

■ Voice Mail and Auto Attendant. Networked systems should have their

555-660-118

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 Ca lling 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, subseq uent callers receive a busy signal.

Issue 1

February 1998

Queue control applies to calls rec eiv ed on the follo w ing types of facilit ies:

■ DID (Direct Inward Dialing)

■ PRI fac ilit ie s pr og r ammed for dia l- plan routin g

■ 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.

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 Position­Busy 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.

New Features and Enhancements

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 t he 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

February 1998

Page xxRelease 6.0 Enhancements

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 sy stem, which m ay ori ginate at exten sions in the Centr ex syst em
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 LEGEND Communications System Release 6.0

System Manager’s Guide

New Features and Enhancements

555-660-118

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, forwardin g featur es ,
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 single­line 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.

Release 3.1 includes all Release 3.0 functionality, plus the enhancements listed
below.

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

*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 a ll o w ed . If the y are allowed, the s yst em’s calling res t r ic tio n s are
reset and the remaining digits that the users dial are checked against the calling
restrictions.

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 sett i ng for all exte ns ions 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 outside 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 messaging systems. The system manager can manually 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 (Hybri d/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.

Forwarding Delay Option 0

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 at 0
up to 9 rings. The factory setting for the forwarding delay is 0 rings (no delay).

Voice Announce on Queued Call Console 0

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-cap able 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.

Release 4.0 has added a

number of calls

limit. If the Overflow Threshold Time option is set to a valid

time

limit for calls in queue in addition to the previous

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 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 Discon nec t. 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.

Seven-Digit Password for SPM 0

Release 4.0 has increased system security by requiring a 7-digit password for
system managers or technicians who use SPM to perform programming or the
Trunk Test procedure. This password is for use in addition to a remote access
barrier code.

Night Service with Coverage Control 0

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.

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 0

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.

Forward on Busy 0

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 (System Access) or ICOM (Intercom)
buttons is forwarded immediately to the programmed destination, preventing the

caller from hearing a busy signal from the intended call recipient’s extension.
