FCC Notification Information
INTERFERENCE
INFORMATION
Federal Communications Commission (FCC) Rules
require that you be notified of the following:
•
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions in this manual, may cause interference to radio communications.
• This equipment has been tested and found to comply
with the limits for a Class A computing device
pursuant to Subpart J of Part 15 of FCC rules, which
are designed to provide reasonable protection against such interference when operated in a commercial environment.
• Operating this equipment in a residential area is likely
to cause interference with radio communications, in
which case the user, at his or her own expense, will be required to do whatever is necessary to correct the interference.
• The MERLIN Attendant is designed to be connected
to the MERLIN Plus system control unit using a Basic Telephone and Modem Interface 2. The MERLIN Attendant is not intended to be connected
directly to the network.
• The MERLIN Attendant is a separately registered
device.
FCC registration number: GRM3U8-19187-CIE

Section 1: Installation Requirements

Overview

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.

KEY FEATURES

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 Attendants REQUIRED

If a customer is using the MERLIN Attendant only for backup call handling or after hours, only one MERLIN. 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.
TABLE 1-4 Calls Per Hour Table
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.
TABLE 1-5 Incoming Lines Table

LOCATION

Number

Number of
Units Needed
3 or fewer 1 4-6 2 6-8 3
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 HANDLING

BACKUP CALL HANDLING

Use the following procedure to administer the MERLIN Attendant for immediate call handling in the
MERLIN Plus system: 1
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
2
stations.
3
Use the receptionist’s voice terminal to program any personal lines for “no ring” at the MERLIN Attendant.
Use the following procedure to administer the
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.
1-8 Administration Procedures

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.
3
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.)
4
Plug the other end of the modular phone cord into the
BTMI-2. (See Figure 1-4.)
