7.2 ROUTER INTERFACE WITH BTS–ASCII–PROTOCOL
7.2.1 GENERAL
The RS–422 router interface permits the control of external BTS crossbars such as
Mars, Venus or TVS.
The following applications are conceivable:
Switching of an emergency crossbar
Connection to upstream crossbars
External Aux buses
An external crossbar can be controlled from the switcher if the crossbar features a
corresponding controller such as:
Mars: CE–300 controller
Venus: SC–400 controller
TVS: CE–2200 controller
Control is also possible with the BTS control system Jupiter provided this is
equipped with the VM–3000 controller.
In addition, the corresponding video and control wiring must be provided. The
ROUTER INTERFACE protocol for the XBAR port is loaded by the switcher as a
standard and need not be selected separately.
The following pages contain more detailed information on wiring and control. The
instruction set for the BTS–ASCII protocol is defined in BCS–3000 ASCII com-
puter interface protocol documentation.
The transfer of the source mnemonic codes from upstream crossbars to the
switcher does not belong to the router interface but is possible with the IDENT
XBAR protocol which can be selected in the CONFIG PANEL installation sub–
menu.
