Section 1: Installation Requirements

Overview
KEY FEATURES
The MERLIN®Attendant answers incoming calls on
designated lines with a prerecorded message and directs
callers to the appropriate extension in the MERLIN Plus
Communications System Release 1 or 2. This equipment
can:
•
reduce the workload of the receptionist
• insure incoming calls are are answered during peak calling
periods
•
answer incoming calls after business hours and on
holidays and weekends
CAUTION: The MERLIN Attendant operates onIy with
the MERLIN Plus Release 1 or Release 2 system and a
Basic Telephone and Modem Interface (2301-BTI)
connected to a MERLIN Plus system station module.
Some of the key features of the MERLIN Attendant are:
•
•
•
Security Code
An authorized caller code that must be entered before
changing any programmable features to protect
recorded announcements and other programming from
being changed by unauthorized personnel.
Remote Programmability
Features, including recorded announcements, can be
programmed from a Touch-Tone phone either on-site
or from a remote location.
Day/Night/Hold Announcements
Specific greetings can be played to callers in response
to the time of day or the status of the call.
Overview 1-1

• System Clock/Weekly Calendar
An internal clock and calendar can track business
hours and days of operation to allow the appropriate
announcement to be played to callers.
• Battery Backup
Routing plans and programming changes can be saved
up to eight weeks following a power outage, provided
the battery is fully charged. Recorded announcements
can be saved up to three hours under the same
conditions.

Equipment and Location Requirements
The following equipment is supplied with the MERLIN
Attendant:
•Power cord with transformer
• 8-foot, 6-wire modular phone cord
• Mounting plate
• User’s Guide
•Basic Telephone and Modem Interface 2 (BTMI-2)
The BTMI-2 must be connected to a station module
housed in the MERLIN Plus system control unit (Release
1 or 2). Up to three MERLIN Attendant units (connected
to three BTMI-2s) can be connected to the module. The
units must be connected, in order, to stations 11, 12,
and 13.
NUMBER OF MERLIN
If a customer is using the MERLIN Attendant only for
Attendants backup call handling or after hours, only one MERLIN.
REQUIRED
Attendant is required unless call traffic is heavy, as shown
in Table 1-4. When call traffic is heavy, the number of
MERLIN Attendants required at a site depends on the
number of calls the customer receives during peak hours.
Refer to Table 1-4 to determine how many
MERLIN Attendants are required.

If the customer does not know the number of calls the
business gets during peak hours, you can estimate how
many MERLIN Attendants are required by asking the
1-6 Equipment and Location Requirements

customer how many incoming lines the business has. Then
refer to Table 1-5 to determine the number of MERLIN
Attendants required.

Units Needed
The number of units needed can also be affected by the
type of calls a customer receives. If there is significant
overflow of unanswered calls to the receptionist an
additional MERLIN Attendant may be needed.
The location for the MERLIN Attendant must meet the
following criteria:
•
Within 5 feet of a properly grounded ac power source
that is not controlled by a switch
NOTE:
If possible, the MERLIN Attendant should
share the same power source with the
MERLIN Plus system control unit. This is
recommended when the MERLIN Plus
system control unit is connected to an
Uninterruptible Power Supply (UPS).
•
Not more than 10 feet away from the MERLIN Plus
system control unit
•
A sufficient distance away from a heating or cooling
source to prevent exposure to temperatures beyond

Administration Procedures
Before installing a MERLIN Attendant, you must install
and administer a Basic Telephone and Modem Interface 2
(BTMI-2) for each unit you are connecting. Perform all the
appropriate administration procedures from a multiline
MERLIN system telephone that is connected to the
MERLIN Plus system control unit.
IMMEDIATE CALL
Use the following procedure to administer the
HANDLING
MERLIN Attendant for immediate call handling in the
MERLIN Plus system:
1
2
3
Program all common lines for “delayed ring” at the
receptionist’s voice terminal (station 10) and
administer a Privacy button.
Program all common lines for “no ring” at all other
stations.
Use the receptionist’s voice terminal to program any
personal lines for “no ring” at the MERLIN Attendant.
BACKUP CALL
Use the following procedure to administer the
HANDLING
MERLIN Attendant for backup call handling in the
MERLIN Plus system:
1 Program a Privacy button for all stations with ringing
lines.
2 Program all common lines for “no ring” at all other
stations.
3 Program Day and/or Night Answer Delay as required
on the MERLIN Attendant for a minimum of five ring
cycles.

b Switch the BTMI-2 to “data” mode.
Place the MERLIN Attendant on a table or desktop, or
mount it using the mounting bracket:
a Using a #10 or smaller screw (wood, sheet metal,
concrete), attach the wall mounting bracket to a
vertical wall surface so that the hook end of the
bracket is down.
b Locate the keyhole opening on the underside of the
MERLIN Attendant with the hook on the bracket.
Slide the unit over the hook and down to secure.
CAUTION: Do not stack multiple MERLIN
Attendants; this will damage the units.
Make sure setup switches 1 and 2 are off, then plug one
end of the modular phone cord into the jack on the
back of the MERLIN Attendant labeled “to line.”
(See Figure 1-3.)
Plug the other end of the modular phone cord into the
BTMI-2. (See Figure 1-4.)
Plug one end of the power cord into the 10 VAC power
connector on the MERLIN Attendant.

NOTE: During a power outage there is no need to use
battery backup to answer calls if the MERLIN
Attendant shares an Uninterruptible Power
Supply (UPS) with the MERLIN Plus system
control unit. If a UPS is not used with the control
unit, incoming calls cannot be answered by the
system during a power failure and therefore
cannot be directed to the MERLIN Attendant.
