Overview
KEY FEATURES
The MERLIN II Attendant answers incoming calls on
designated lines with a prerecorded message and directs
callers to the appropriate extension in the MERLIN® II
Communications System Release 3. This equipment can:
●
reduce the workload of the receptionist
●
insure incoming calls are answered during peak calling
periods
●
answer incoming calls after-hours and on holidays and
weekends
CAUTION: The MERLIN II Attendant only operates
with the MERLIN II Release 3 system and a 517C 13
Basic Telephone (012) Module.
Some of the key features of the MERLIN II 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/Transfer Announcements
Specific greetings can be played to callers in response
to the time of day or the status of the call.
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.

Call Supervision
The MERLIN II Attendant can supervise calls and
monitor the progress of calls.
•
Alternate Routing
When the first requested extension is unavailable,
callers can be transferred automatically to an
secondary extension.
•
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.
There are three lights on the front panel as shown in
Figure 1-1. The lights indicate the following:

User’s Guide
Also required, but not supplied, is a 517C13 Basic
Telephone (012) Module housed in a MERLIN II Release
3 system control unit. Up to four MERLIN II Attendants
can be connected to the module.
When the maximum of four MERLIN II Attendants are
connected to the module, no basic telephones intended for
call handling should be connected to any of the remaining
eight ports. However, when programming MERLIN 11
Attendant features, you can connect a basic Touch-Tone
telephone to one of the remaining eight ports to perform
the programming procedures.
NOTE: If a 400 w/TTR module is present in the system,
there is no limit to the number of basic
telephones that can be connected to the Basic
Telephone module with Merlin II Attendant
units.
If a customer is using the MERLIN II Attendant only for
backup call handling or night service, only one
MERLIN 11 Attendant is required unless call volume is
heavy, as shown in Table 1-3. When call traffic is heavy,
the number of MERLIN II Attendants required at a site
depends on the number of calls the customer receives
during peak hours. Refer to Table 1-3 to determine how
many MERLIN II 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 II Attendants are required by asking the
customer how many incoming lines the business has. Then
refer to Table 1-4 to determine the number of MERLIN II
Attendants required.
TABLE 1-4 Incoming Lines Table
Number Number of

The location for the MERLIN II 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 II Attendant should
share the same power source with the
MERLIN II system control unit. This is
recommended when the MERLIN II system
control unit is connected to an Uninterruptible
Power Supply (UPS).
1-8 Equipment and Location Requirements

•
Not more than 10 feet away from the MERLIN II
system control unit
•
A sufficient distance away from a heating or cooling
source to prevent exposure to temperatures beyond
32 °F to 104 °F (O °C to 40 °C)
Equipment and Location Requirements 1-9

Administration Procedures
Before installing the MERLIN II Attendant you must
administer a port on the Basic Telephone (012) module for
each unit you are connecting.
CAUTION: Do not administer the port for outward call
restriction.
While you are performing administration procedures, you
should also administer the lines that will be assigned to the
MERLIN II Attendant(s). Ask the customer which lines
are being answered by the MERLIN II Attendant,
including backup call handling and Night Service.
If you are installing more than one MERLIN II Attendant
to answer the same lines or line pools, you need to assign
these ports on the Basic Telephone (012) Module to the
same Call Distribution Group to prevent call contention
between the units.
Perform all the appropriate administration procedures
from the MERLIN II System Display Console:

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