Using the CONNECT Command
When a CONNECT command is issued, a PU must be configured either as
permanently subordinate to the line specified in the CONNECT command, or must be
selected from the switched floating PUs configured under the SNAX/XF service
manager. SNAX/CM searches the PUs assigned to the SNAX/XF service manager
process (for switched floating lines) or the PUs assigned to the line (for permanently
subordinated lines) for the identified PU. The PU can be either the PU name or a
matching CALLADDR and PUID specification.
When PUs with no CALLADDR or PUID name specified are used for call-out
operations, the CALLADDR, PUID, and PU name must be supplied using the
CONNECT command. SNAX/CM then selects the PU using the PU name.
One SNAX/CM process can handle a maximum of 254 active connections. The total
connections include successful responses to SNAX/CM ENABLE commands, as well
as successful and in-process CONNECT commands.
SNAX/CM returns a CONNECT COMMAND ACCEPTED message to the OUT file
when the command is forwarded by SNAX/CM to the SNAX/XF service manager.
SNAX/CM logs the result of any attempt to connect the line in the log file.
If SNAX/XF fails to connect the line/port, SNAX/CM sends a message to the log file.
If a PROCESS server is defined, SNAX/CM sends a COMMAND REJECTED or
DISCONNECTED message to the PROCESS server.
This first example shows how the CONNECT command can be used for a single-PU
line:
-> CONNECT LINE $SNAP1,PROCESS $CCC, PU $SSCP.#PU, &
CALL "123456789", XID %HABCD1234
where:
$SNAP1 is a single-PU line with the ASSOCIATESUBDEV value already defined
in the SCF operation.
$CCC is a user-written program that gains control after the connection is
completed, fails, or is disconnected.
$SSCP.#PU is a switched floating PU to which the command is directed.
"123456789" is the number to be called.
%HABCD1234 is the XID information string for the PU called.
