TIWAY 1 TI505 NIM User Manual
2.1.1 Communication
Media
The following signal-transmission media are supported by TIW
A
Y I:
RS-232-C/423 dedicated lease-line modem interface in which no dial-up is
necessary,
providing extended (cross-continental) geographic coverage.
RF or short-haul modem link-ups (cross-plant or cross-town coverage).
Siemens Local Line (up to 25,000 feet).
NOTE
TIWAY I does not directly support dial-up modems which
require Modem Control Commands for communication
switchover.
This can be done, but specific equipment is required
to
dial the remote number from the host device.
You
can select from either type of media for the network, but you cannot mix the types of
media.
