Chapter 1 - Introduction and Description
The CC1600 is a generic rack that accommodates a variety of
rackmount modems and DSUs. The CC1628 series is
designed specifically for V.34 modems. Both rack models
come in -11L and -21 versions. The -11L version connects to
standard RJ11 telephone phone cords. The -21 version has
three 50-pin connectors for dial-up and 2-wire or 4-wire leased
lines. Both models are equipped for universal AC input or
-48v DC. Finally, both models are available with either a
single power supply or dual (redundant ) power supplies for
uninterrupted power. A single power supply can maintain a full
complement of modems.
The CC1600-series rack makes it easy for you to monitor your
data communications. Each modem has its own set of LEDs,
with separate indicators for Receive Data, Transmit Data,
Carrier On, Speed, Off Hook, Data Terminal Ready, Ring
Indicator, and Error (Out-of-Service and Busy).
The rack measures 19" wide, 7" high, and 15" deep. The rack
is usually mounted in the same cabinet as your computer, or
can be enclosed in a separate cabinet of its own. Modems are
installed by simply opening the rack front door and sliding in
the modems. RS232C cables and phone cords are connected
to modem connectors at the back of the rack.
