Coms Port Parameters
These are the parameters for the control terminal i.e. baud rate, parity, stop bits and data bits.
Note that changing these parameters will mean that the user will have to change the terminal
setup to match.
Terminal Type
You can select a terminal type by typing <space>. Supported terminals are ANSI, ANSI-
Colour and Wyse-50.
BRI S/U Power Feed
Setting this to On enables power feeding to the ISDN S0-interfaces and U interfaces for any
terminal adapters, ISDN telephones or NT-1's that require it.
BRI S Power Feed
This field allows you to switch the power from normal mode to restricted mode, i.e. the
power provided at the ISDN BRI So interface will switch polarity. This field should usually
be set to Normal. Current limiters allow 25 mA per port in normal mode and 10 mA per port
in restricted mode. This is equivalent to 1 W and 400 mW at 40 V.
BRI U Power Feed
Current limiters on the U interfaces allow 20 mA per port in sealing mode and 40 mA per
port in normal mode. This is equivalent to 1 W and 400 mW at 40 V.
