EnvoyACP/XF Lines and Line-Handler Processes
Electrical Interfaces
The following electrical interfaces are available with the ServerNet WAN concentrator:
RS-232
RS-422
EnvoyACP/XF Lines and Line-Handler Processes
Each EnvoyACP/XF line has an associated line-handler process; that is, a one-to-one
correspondence exists between EnvoyACP/XF lines and EnvoyACP/XF line-handler
processes. To add an EnvoyACP/XF line, you add an EnvoyACP/XF line-handler
process object; a corresponding LINE object is defined automatically.
PROCESS, DEVICE, and PROFILE Objects
In the WAN subsystem, you can change the line-handler process modifiers in two
ways:
•
By defining a new PROFILE object and using the ADD PROFILE command to
specify the modifiers.
•
By using the ADD DEVICE command to specify the modifiers.
See the WAN Subsystem Configuration and Management Manual for details about
these two methods of changing line-handler process modifiers.
WAN Subsystem Configuration Database
The WAN subsystem configuration database stores the PROFILE objects (containing
the EnvoyACP/XF line-handler process modifiers) and the DEVICE objects.
(Throughout the remainder of this manual, the WAN subsystem configuration database
is called the configuration database.)
SCF Command Routing
The Subsystem Control Process (SCP) routes an SCF command to the correct
subsystem based on the object name in the command. In the following example, SCP
sends the ADD DEVICE command to the WAN subsystem based on the object name
(#EXF01):
-> ADD DEVICE $ZZWAN.#EXF01...
Similarly, in the next example, the SCP sends the STATUS LINE command to the
EnvoyACP/XF subsystem based on the object name ($EXF01):
-> STATUS LINE $EXF01
