Chapter 1 - Introduction
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.
