ASCII terminal jack
The front panel CRAFT jack of the master NCC 2020 is used for a local
ASCII terminal connection. This 6-pin miniature modular jack provides a
direct RS-232 connection without flow control to the local terminal.
This jack is equipped with an auto-baud feature, which is activated upon
power-up. When the master NCC receives a carriage return (CR or 0DH)
at a rate of 300, 600, 1200, 2400, 4800, 9600, or 19,200 baud, this port is
programmed to operate at the ASCII terminal’s rate. Pressing the BREA
key on the terminal for one second resets the baud rate, or disconnecting
the cable from the terminal to the CRAFT jack also resets the baud rate.
Refer to the Access System 2000 ASCII Terminal Operation manual for
instructions on connecting the ASCII terminal to an Access System 2000
node. For information on using the ASCII Terminal Interface (ATI) with
REMS, see Chapter 7, Performance monitoring.
Signal access jacks
The NCC 2020 front panel also has three pairs of bantam jacks for signal
access by an external T1 test set. Fi gure4-5, NCC Signal Access Jacks
shows the wiring of these jacks.
