The rear card supplied with the Model 1001CC is equipped with two
modular RJ-45 jacks (see Figure 1, below). The jack labeled “A1” is for
connection to the RS-232 terminal. If the Model 1001CC is being used
in a daisy-chain application, port “B1” provides the link to the next
Model 1001CC in the chain.

2.2 DESCRIPTION
The Model 1001CC RS-232 Rack Mount Controller Card fits in
Patton’s NetLink Rack Chassis and Cluster Boxes and allows the
Patton NetLink Rack Cards to be controlled from an asynchronous RS-
232 terminal.
Taking up one card slot, the Model 1001CC provides a modular
port for connection of an RS-232 terminal, and a serial port for daisy-
chaining between racks. The user wishing to “dial” or configure a
particular NetLink card simply keys in an addressable command, which
the Model 1001CC passes along to all the cards in the rack. The
appropriate card recognizes its address and responds to the command.
Combining local and remote daisy chaining, a single RS-232
terminal can control a whole network of rack-mounted NetLink DSL
modems, CSU/DSUs or fiber modems. The Model 1001CC has front
panel LED indicators for Power, TD and RD.

INSTALLATION NOTE: The Model 1001CC communicates with the function
cards using an internal bus in the rack. In order to ensure proper
communication between the cards, it is recommended that all rear cards,
including the 1001CC rear card, are configured to have FRGND and SGND
connected through a 1000 Ohm resistor. This is done by setting jumpers on
the rear card. Please see the manual associated with your function cards for
more information on installing these jumpers.
