AT&T MERLIN 3070 Administration Manual page 12

2. Processor Module: Works in conjunction with
Feature Module 5 to control system operating
conditions.
Switches A, B, C, D, E, F, G, and H. Select
system options provided by Feature Module 5.
Warning light. Red light warns of problem in
control unit. It also comes on for approximately
one minute when you first turn on the system.
3. Feature Module 5: Contains the software that con-
trols your MERLIN system. You set eight switches on
the Processor Module, according to the labels on the
Feature Module, to select the following options from
the programs stored in Feature Module 5:
Attendant/Administer (10) option. Selects at-
tendant or administration mode of operation for
the administrator/attendant console.
NormaI/Attendant (11, 12, 13, 14) options.
Select normal or attendant mode of operation for
these four voice terminals.
Pooled/Square option. Selects mode of opera-
tion for the system so that line buttons on voice
terminals represent either groups of lines
(pooled) or separate lines (square). For detailed
information on this option, see "The Square vs.
Pooled Decision," page 17.
Dial Access/Button Access option. Sets the
system so that a line pool can be accessed at a
voice terminal either by touching the button to
which the pool is assigned or by touching a Pool
Access button and then dialing the access code
for that line pool.
. 1-8 Lines/ 8 Lines option. Sets the system size
to eight or fewer outside lines (small system) or
to more than eight lines (large system).
4. Diagnostics Module (optional): Aids in identifying
faulty components if the system malfunctions.
5. SMDR (Station Message Detail Recording) Module
(optional): Allows connection of a printer so you can
print out call traffic reports automatically as calls are
made. The SMDR Module is also required for
automatic operation of Enhanced Night Service with
Time Set.
6. Services Module (optional): Contains the following
jacks, switches, and adjusters to connect and control
optional equipment:
PFTT (Power Failure Transfer Telephone) jack.
With an adapter, connects up to four standard
modular telephones for use as backup during
commercial power outage. The system
automatically switches service to them if power
fails.
Extra Alert jacks. Three jacks connect strobe
lights, loud bells, or horns for three noisy or
remote zones where the regular voice terminal
ring cannot be heard.
Page jack. Connects a loudspeaker paging
system. With an adapter, you can have up to
three paging zones.
Music-In jack. Connects a music source for
Music-on-Hold or background music through a
paging system.
Bkgd Vol (Background Volume) control. Allows
volume adjustment for background music.
MOH Vol (Music-on-Hold Volume) control.
Allows volume adjustment for Music-on-Hold.
Page Sgnl switch. On (up) provides a short tone
before loudspeaker paging announcements. Off
(down) eliminates the signal.
Level switch. Sets amplification for music
source. Hi (down) is for sources with their own
amplifiers; Lo (up) is for those without.
7. Line Module: Provides jacks for up to five outside
lines. Normally, there are two Line Modules in the
Model 1030 control unit. You may have a third,
however, if you decide to replace the Voice Terminal
Module normally found in slot 11 with a Line Module
in order to have 15 lines instead of 10 (1520 configura-
tion). If you want to add an Expansion Unit, however,
you must first return your control unit to the 1030
configuration.
The Expansion Unit contains up to four Line Modules.
These modules, combined with two Line Modules in
the 1030 control unit, provide the system maximum of
six Line Modules (30 lines).
Jacks O, 1, 2, 3, 4. Connect outside lines to the
MERLIN system. Line Modules have letters as
well as numbers. For example, the first Line
Module in the control unit is lettered A, so the
jacks in that Line Module are called A0, A1, A2,
A3, and A4.
8. Voice Terminal Module: Provides jacks for ten voice
terminals. You may have up to three Voice Terminal
Modules for the Model 1030 control unit and up to four
additional Voice Terminal Modules in the Expansion
Unit. A Basic Telephone Module with jacks for basic
Touch-Tone or rotary telephones is also available.
"0" begins the numbering for the first five voice
terminal jacks on the module. These jacks (and
the location of the module) determine the inter-
com numbers of the voice terminals plugged in-
to them. For example, if a Voice Terminal Module
is plugged into the slot labeled "Intercoms
20-29," the jack labeled "O" is for intercom 20.
The jack below it is for intercom 21, and so on.
"5" begins the numbers for the second five voice
terminals.
9. Module C (optional): An Off-Premises Telephone in-
terface to support off-premises telephones.
