AT&T PARTNER Installation And Use Manual page 100

Two #8 screws—for mounting the system on a wooden surface—are included
with the system. If you are mounting the system on wallboard, metal, or
masonry, use the proper fasteners for the wall type and weight of the system
(approximately 11 lbs. or 5 kg.). Purchase them at any hardware store. You will
also need a screwdriver to mount the system.
You will need a standard touch-tone or rotary phone for testing the installation.
In addition, if you need modular telephone cords for connecting the extension
jacks on the system modules to the modular connecting blocks for extensions in
the equipment room, or short telephone cords for wall mounting MLS-model
phones, order them before installation. Refer to "Product Ordering Information"
in Appendix D for ordering instructions.
Installation Guidelines
System Modules
The first module must be a 206 module.
The second module can be a 206 module (for 2 additional lines and 6
additional extensions) or a 200 module (for 2 additional lines only). If you
add a Release 3 206 module to an existing system, you must install it in
the leftmost slot in order to have access to Release 3 system features.
If your system has only one module, you can install it on a wall or on a flat
sturdy surface above the floor (such as on a table or desk). Wall
mounting is recommended.
If your system has two modules, you must mount it on a wall.
Telephones and Devices
You can connect the following telephones and devices to the system:
MLS- and MLC-Model Phones. System phones require at least two-pair
wiring and are compatible with AT&T 4-pair SYSTIMAX™ wiring.
Industry-Standard Devices. Industry-standard devices (including
standard phones) require one-pair mounting cords; AT&T D2R mounting
cords are recommended.
– Standard Phones. Connect standard phones to the system for:
–
–
Power Failure Operation. During a power failure, system phones
will not work because they require power to operate. However, if
you connect standard phones to extensions 10 and 16, users can
place and answer outside calls on lines 1 and 3, respectively. You
can connect a standard phone either alone or combined with a
system phone. (If you combine a standard phone and a system
phone on one extension, you may want to turn off the standard
phone's ringer during normal use.)
Internal Hot Line Phone. A standard phone, rather than a system
phone, should be used as an internal hot line phone; but, any type
of phone can be used as an alert extension. Do not connect an
internal hot line phone to extension 10 or 16 to keep them available
for power failure use.
