wkst. no. Workstation number, as for a normal terminal.
area no. Area number, as for a normal terminal.
call (dte) For an ‘X25.SVC.IN’ or ‘X25.SVC.IO’ this number
specifies the remote X.121 subscription address from
which this virtual circuit will accept an incoming call.
If omitted, then any remote address will be allowed to
establish a call on this virtual circuit and the address
will remain set in the physical terminal table from then
on. An ‘X25.SVC.NULL’ is basically the same as an
‘X25.SVC.IO’ but is not allowed to have a call address
initially configured, and when the virtual circuit
changes state to the IDLE state the address is cleared
back to NULL. For an ‘X25.SVC.AUTO’ or ‘X25.SVC.IO’
this number is required to set the X.25 address to
which a call will be made when the SVC terminal is
enabled.
call (dce) For an ‘X25.SVC.IN’ or ‘X25.SVC.IO’ this number
specifies the X.121 subscription address which this
virtual circuit will accept as the called address in an
incoming call. If omitted, then any called address will
be accepted and a call established on this virtual
circuit. For an X25.SVC, X25.SVC.AUTO or
X25.SVC.IO this number is not required.
The call number is not specified for a permanent
virtual circuit.
name Choose a meaningful description of the X.25 virtual
circuit, preferably including the remote subscription
address where such is specified. This field is used in
some ZMNTR displays.
option Option Word Override (optional). This keyword allows
you to override the value of the device option word
parameter for this virtual circuit. This is useful for
requesting that receiving applications be notified when
CALL, CALL conf, RESET, or CLEAR is received, or for
specifying that an acknowledgment is required from an
application for incoming calls. These options are
described in the section “Device Option Word
Definition” below.
