Configurations That Require Multiple VTCPD

Each instance of VTCPD supports a single message format. If the Avaya Media

Processing Server must communicate with TCP/IP hosts using multiple formats, the

system must be configured with an instance of VTCPD for each format.

By default, Resource blocks that contact VTCPD broadcast requests to all VTCPD

attached to the same VMST. If the system uses multiple VTCPD, the application must

specify the particular instance of VTCPD (see Communicating With the Host on

page 72.)

Specifying Which VTCPD

If the system supports multiple VTCPD for multiple message formats, each VTCPD is

configured to with a unique name. The VTCPD names are specified in

$ASEHOME/etc/services. The command vtcpd -n <name> is used to

specify the VTCPD (see Attaching to VMST on page 34.)

Specify the VTCPD name in the Resource block that contacts VTCPD. For example:

Using the VTCPD Port Number

VTCPD returns the port number as condition data associated with gotres. The

format of the condition data is XXX:YYY:ZZZ where XXX is the connection number,

YYY the slot number, and ZZZ the port number.

The following demonstrates an application that uses the port number to send data to

the appropriate VTCPD.
