Using the Control Terminal Port
The RS-232 Control Terminal Port allows you to connect the integrated access system to a
local VT100-compatible terminal, which you can then use to control the system. This port is
configured as a DCE interface.
Connect your local terminal to the TERM jack of the INF-E card. This is an RJ-48 jack in
compliance with EIA-561. Figure C-16 shows the pin locations on this jack, and Table C-13
lists the signal pinouts.
