2.00 System Interface
The programming and diagnosis can be accessed either locally or remotely using the system RS-232C
interface.
The system may be configured for local direct access from the data terminal, or via a modem connection
that allows the data terminal to be located at a greater distance from the system than is allowed for an
RS-232C interface.
For remote access, a data terminal and modem are required at the maintenance location, and the RMT
card (Modem) at the system.
Two RS-232C interfaces are provided by the system.
These connections provide communication either locally or remotely between the system and devices for
programming and diagnostics, external system programming data storage and Station Message Detailed
Recording (SMDR). SIO #2 is used for SMDR only. SIO #1 is for programming and diagnostics, and
external system programming data storage functions.
Typical devices would include VT220, compatibles, personal computers and line printers.
Refer to Section 10-D-7.00 "Communication Interface" for further information.
