The 206EC and 400EC modules support the Caller ID feature. These modules
are required to provide Caller ID information on system display phones. You
must subscribe to Caller ID service from your local telephone company (if it is
available), and connect any lines associated with this service to the line jacks on
the 206EC and/or 400EC modules. Hereafter, references to 206 modules
include 206E, 206EC, and all 206 modules used with previous releases of the
product. Similarly, references to 400 modules include 400E, 400EC, and all 400
modules used with previous releases of the product.
NOTE:
A system display phone—either an MLS-34D, MLS-18D, or MLS-12D—is
required for system programming at extension 10 and/or 11. (Make sure that
the programming phone is as large as the largest phone in the system, because
an MLS-12D or MLS-18D cannot program an MLS-34D. Similarly, an MLS-12D
cannot program an MLS-18D.)
Installation Guidelines
Telephones and Devices
You can connect the following telephones and devices to the system:
■
■
■
MLS- and MLC-Model System Phones. System phones require at least
two-pair wiring and are compatible with AT&T 4-pair SYSTIMAX® wiring.
Call Assistant Intercom Autodialers with Busy Indication
(MLS-CA24). You can connect up to two Intercom Autodialers to the
system phone at extensions 10 and 11 (maximum four per system). The
Intercom Autodialer has its own power supply, which must be plugged
into an AC outlet.
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 touch-tone or rotary dial
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, 16, 22, 28, 34,
40, 46, and 52, users can place and answer outside calls on lines
1, 3, 5, 7, 9, 11, 13, and 15, 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.)
–
Hotlines. A hotline extension should have a standard phone,
rather than a system phone, but can ring any type of phone. A
hotline phone can also be set up to ring the paging system, so
announcements can be made over the loudspeaker. Do not
connect a Hotline phone to extension 10, 16, 22, 28, 34, 40, 46, or
52, to keep them available for power failure use.
