ISDN Cards
The S/T and U AccessBuilder ISDN adapter cards each have four ports. The U
version, with an integrated NT1, is designed for direct connection to ISDN
lines in North America, while the S/T version is designed for use in Europe
and Japan. The S/T card connects to a network terminator unit, which in
turn, connects directly to the ISDN line.
Three status indicator are located to the left of each port (because both
cards look similar, only one is shown)
