							Account Code Entry, Optional
Account Code Entry,
Description
Optional Account Code Entry
incoming and outgoing calls.
Optional
allows voice terminal users to associate an account code with
The account code is appended to the SMDR call record and
can be used later for accounting or billing purposes.
For an incoming call, the user must enter the account code at the end of the call. For an
outgoing call, the user has a choice of entering the code at the beginning of the call, before
the destination is dialed, or at the end of the call. An account code entry is terminated when
the number of digits entered equals the number administered for system account codes,
when # is entered, or when the user hangs up. The procedures for associating an account
code with a call are as follows:
l Single-line Voice Terminal User
Get dial tone (by going off-hook at the beginning of a call or by flashing the
switchhook before hanging up) and dial V 0; then dial the account code directly or
dial a System or Personal Speed Dialing Number that contains the account code. If
the code is dialed incorrectly (before the last digit), redial V 0 and the correct number.
l Multiline Voice Terminal User
At the beginning of an outgoing call, get dial tone and dial V 0; then dial the account
code directly or dial a System or Personal Speed Dialing Number that contains the
account code. If the code is dialed incorrectly (before the last digit), redial V 0 and
the correct number. At the end of a call, press ACCT ENTRY and enter the code
before hanging up. A Repertory Dialing (REP DIAL) button can also be used to enter
an account code. If the code is dialed incorrectly (before the last digit), press ACCT
ENTRY again and dial the correct number.
When the correct number of account code digits has been entered (or # is entered to signal
end-of-dialing), confirmation tone is returned to the user, and the account code is appended
to the SMDR call record.
Considerations
Optional Account Code Entry provides an easy method of allocating the costs of specific
calls (and associated staff time) to the correct project, department or user. The account
code is appended to the SMDR call record and sent to the SMDR output channel.
Account Codes can contain up to 15 digits.
The system does not check the validity of account codes. It only checks for the proper
number of digits or the code terminator #.
If the user is active on a call, invoking the feature will drop the call.
2-11 
						

							FEATURES AND SERVICES
Erroneous account codes that are not corrected before the last digit is entered are recorded
and cannot be changed. Partial account codes entered by going on-hook before completing
the entry are recorded and cannot be changed.
If, before all digits have been entered, (1) the user goes on-hook, (2) a button other than
ACCT ENTRY is pressed, or (3) 30 seconds have elapsed since the feature was invoked, the
SMDR call record will show the digits dialed up to that point.
Optional Account Code Entry cannot be invoked for a call on hold.
Interactions
The following features interact with Optional Account Code Entry
Bridging of System Access Buttons:Account codes can be entered for incoming or
outgoing calls on Bridged Access buttons using normal feature operations.
Callback Queuing: An account code entered before queuing is saved for SMDR.
Conference: If more than one user attempts to enter an account code on a Conference Call,
the first to enter a code will prevail.
Display: When a user activates the Account Code Entry feature by dialing V 0 or pressing
ACCT ENTRY, the system displays the prompt ACCT?. As the user enters the account code,
the digits are displayed to the right of the prompt.If the number of digits exceeds 9, the
system automatically scrolls to Screen 2; the continuation character “-” and the remaining
digits appear on Screen 2.
The prompt and digits remain displayed until one of the following occurs:
l The user enters either “#” or the administered number of code digits.
l The user restarts the Account Code Entry feature by dialing V 0 or pressing ACCT
ENTRY again, to correct an erroneous entry.
l The system time-out for Account Code Entry is reached.
l The user selects another button that overwrites the display.
Remote Access: Remote access callers cannot enter account codes.
Repertory Dialing: An account code can be stored on a REP DIAL button.
Speed Dialing: An account code can be stored in a System or Personal Speed Dialing code.
Transfer: A user can transfer a call to another user, then, before hanging up, enter an
account code. Subsequent account code entries for the same call will be ignored, even
though confirmation tone has been returned.

							FEATURES AND SERVICES
Attendant Call Extending
Description
This feature allows the attendant to put a call in a special hold condition, call another station,
then connect the two calls together.The attendant can withdraw from the connection and
separate the call from the console or remain connected to the other parties. Attendant Call
Extending is a feature used at either a Direct Trunk Attendant Console (DTAC) or a Switched
Loop Attendant Console (SLAC).
Note:In general,
the attendant should not use the TRANSFER button, which
invokes the standard multiline voice terminal Transfer feature, to extend calls.
If Transfer is used, busy or unanswered calls cannot return to the attendant
console for further handling.
The attendant, after placing or answering a call, can use Procedure 1 or 2 to extend this call
to an inside extension or Procedure 1 to extend it to an outside number:
1. Press START to place the incoming call on hold via the Attendant Splitting One-Way
Automatic feature. After receiving Dial Tone, the attendant then dials the requested
inside or outside number.
or
2. Press the Selector Console Group Select and Direct Extension Selection (DXS)
buttons associated with the requested inside station. This operation is equivalent to
pressing START and dialing the extension.
If ringing tone is heard, the attendant presses RELEASE (Manual Release) to connect the
caller to the ringing line and separate the call from the console. As an alternative, a DTAC
attendant or a SLAC attendant (with Automatic Release administered) can go straight to
another call by pressing any facility button,such as System Access, Loop, Automatic
Intercom, or an outside line; this completes the call extending procedure. (If a SLAC
attendant has Automatic Hold administered instead of Automatic Release, pressing a facility
button simply puts the incoming call on hold and does not extend it.)
The attendant has the option of staying connected to the ringing line to announce the call
before connecting the two parties.The attendant can then release or (SLAC only) join the
other parties in a 3-way connection by using the Attendant Join feature.
If busy tone is heard and Attendant Camp-On (see associated feature description) is not
desired, the attendant presses CANCEL and is reconnected to the calling party.
If busy tone is heard on a call to an inside station and Attendant Camp-On is desired, the
attendant presses RELEASE. The called party hears a tone burst, and the call waits at the
called voice terminal.When a busy single-line station goes on-hook, or a busy multiline
station System Access button becomes idle, the call automatically begins ringing at the
station.
2-14 
						

							Attendant Call Extending
Calls extended to an idle voice terminal that are not answered within a specified time return
to the Attendant Console on an idle LOOP button (SLAC only) or on the Return-On-Don’t-
Answer (RTN-DA) button (DTAC only). Calls camped-on at a busy voice terminal that are not
answered within a specified time return to the Attendant Console on an idle LOOP button
(SLAC only) or on the Return-On-Busy (RTN-BUSY) button (DTAC only). If a SLAC is not
available to incoming calls (busy on another call, in Position Busy mode, etc.), a returning call
remains in the console queue until the console can handle it. If the Return buttons on a
DTAC are busy, an extended call remains at the called terminal until that button becomes
idle.
Considerations
Attendant Call Extending allows the attendant to utilize the additional attendant related
features such as Attendant Splitting One-Way, Release, Cancel, Return-On-Don’t-Answer,
Return-On-Busy, Forced Release (SLAC), Join (SLAC), and Source/Destination (SLAC).
For information on related Attendant Features (Table 2-E), refer to the individual feature
descriptions.
Interactions
The following feature interacts with Attendant Call Extending.
Forwarding: Calls extended by an attendant to a forwarding station will be given normal
Forwarding treatment.
Administration Requirements
System:
l Number of seconds before a Camped-On call returns to the Attendant Console (1-
120 or 0 for no Attendant Camp-On; default = 30).
l Number of rings before unanswered call returns to the Attendant Console (1-31;
default = 5).

							FEATURES AND SERVICES
Attendant Camp-On
Description
This feature allows the attendant to extend a trunk call to a busy voice terminal and leave it
waiting or “camped on” there.After hearing busy tone, the attendant presses RELEASE to
camp-on this call at the busy terminal.When this is done, a burst of tone is heard in the
handset of the called terminal and the caller is placed on hold (hearing music-on-hold if
available). When a System Access button at a multiline set becomes idle or a single-line
terminal hangs up, the camped-on call is connected automatically and ringing begins.
Considerations
A camped-on call can be answered by a busy single-line user without losing the current call
by momentarily pressing the switchhook (which places the current call on hold) and then
dialing V 9. Multiline terminal users cannot do this. However, if they have a System Access-
Originate Only button, they can place all other calls on hold, go off-hook on that button and
dial V 9 to pick up the camped-on call.
If the camped-on call is not answered within a specified time, the call will be returned to the
Attendant Console in one of the following ways:
l Switched Loop Attendant Console
The call returns to the common queue, where it remains until the console can receive
it at a LOOP button.
l Direct Trunk Attendant Console
The call returns to the Return-On-Busy (RTN-BUSY) button. If that button is busy,
the call remains camped-on at the called terminal until the RTN-BUSY button of the
console becomes idle.
For information on related Attendant Features (Table 2-E), refer to the individual feature
descriptions.
Interactions
The following features interact with Attendant Camp-On.
Call Waiting: Trunk calls camped onto a station by an attendant are given priority over other
waiting calls.
Callback Queuing: Trunk calls camped onto a station by an attendant are given priority over
queued calls.
Coverage: If the called party is a sender in a Coverage group and all receivers of the
Coverage group are busy, the call will camp onto the originally-dialed station. Once
camped-on, calls will no longer receive coverage even if a coverage receiver becomes idle.
2-16 
						

							Attendant Camp-On
Direct Group Calling: The attendant can camp-on more than one call per DGC group. Voice
terminals in the group do not receive a burst of tone when a call is camped on. Trunk calls
camped onto a busy DGC group go into the DGC queue and are eligible for delay
announcement and music-on-hold.
Direct Inward Dialing (DID): DID calls can be covered by the attendant and then given
Camp-On treatment. They do not automatically receive Call Waiting.
Station Hunting: If the called party is a member of a hunt group and all members of the
group are busy, the call camps onto the originally-dialed station. Once camped-on, calls will
no longer hunt even if another member of the hunt group becomes idle.
Administration Requirements
System:
l Number of seconds before a camped-on call returns to the Attendant Console (1-120
or 0 for no Attendant Camp-On; default = 30).
2-17 
						

							FEATURES AND SERVICES
Attendant Cancel
Description
This feature allows the attendant to terminate an attempt to extend any incoming call if the
called station does not answer, or if the station answers but declines to accept the call. The
attendant presses CANCEL and is automatically reconnected to the calling party. The call
can then be ended by hanging up or by pressing RELEASE.
Pressing CANCEL when the Start facility is not active will be ignored.
Considerations
Attendant Cancel allows the attendant to terminate a call transfer attempt and return to the
incoming held party via a one-button operation.This enhances the attendant’s ability to
handle calls quickly and efficiently.

							Attendant Console, Direct Trunk
CONSOLE
Attendant Console, Direct Trunk
Description
In System 25, the Attendant Console is used to answer incoming trunk calls that are not directed to
specific user stations, to answer calls from inside users, to extend calls to inside stations and
outside numbers, and to assist system users in placing outgoing calls and setting up conferences.
The attendant can also manage and monitor some areas of system operation. System 25 supports
either the Direct Trunk Attendant Console (DTAC) or the Switched Loop Attendant Console (SLAC),
which is covered in the next feature description in this manual. Consoles of both types cannot be
installed in the same system.
The DTAC (Figure 2-1) can be one of the Merlin Communications System multiline voice terminals
listed below, administered with special features, buttons, and capabilities to serve as an attendant
position.
l 7305H02D (34 programmable feature buttons, each with I-use and status LEDs)
l 7305H03B (34 programmable feature buttons; built-in speakerphone)
l 7316H01A (34 programmable feature buttons, each with I-use and status LEDs; built-in
speakerphone)
In addition to the attendant features, most standard multiline terminal features are also available.
(Refer to Section 4, “Hardware Description,” for a complete identification of the external controls,
indicators, and components of the DTAC voice terminal.)
