The RAT is a modem card that installs on the
XC
card. The card is used to
remotely administer the system through a trunk line.
l
Two versions of the RAI card are available. Both versions use 1 Stop bit, 8
data bits, and no parity. The RAI-A card has a fixed baud rate of 300. The
RAI-B card supports both 300 and 1200 baud operation. The following
table shows the transmission rate of each card along with the SCC version
compatibility.
