You can control the background music volume either at the audio source or at

the administrator/attendant console.

OUTSIDE TELEPHONE

LINES

Your local telephone company gives you the telephone numbers for your

outside lines. The control unit jacks where the outside lines connect to the

system are labeled alphabetically: A through D for a system with four or

fewer outside lines, and A through H for a system with five to eight outside

lines.

To simplify system administration, plan to assign your outside lines to an

unbroken sequence of jacks beginning with jack A. Begin with the lines for

your local published telephone numbers. Group special line types such as

WATS lines together in the sequence, and place any personal lines at the end

of the sequence.

Under “Outside Telephone Lines” . . .

Write in the telephone number and the line type for each of your outside

lines next to the appropriate letter.

If you have an optional loudspeaker paging system that you are planning

to connect to a CO line instead of the Paging jack on the Control Unit,

write “CO Paging” under line type for the CO line you plan to use for

paging-

HOLD DISCONNECT

INTERVAL

The MERLIN Plus system comes set for a long (450 milliseconds) hold

disconnect interval because most telephone company switching systems use

the long interval. If your telephone company uses a short (50 millisecond)

interval, you’ll need to reset your system to prevent calls from remaining on

hold after callers have hung up. Refer to “Hold Disconnect Interval” in

Section 5, “Reference,’ for more information on how to detect the hold

disconnect interval.
