VTCPD The VPS Transmission Control Protocol Daemon is the software

process that facilitates communication between Avaya application

programs and one or more external hosts through TCP/IP or UDP

(User Datagram Protocol) connections. Each instance of VTCPD can

support a single message format.

For information about configuring the Avaya MPS for VTCPD, see

the Avaya MPS System Reference Manual. For information about

programming applications to use VTCPD, see the Avaya MPS

Application Programming Reference Manual.

VT assignments Host-phone line mapping. By default, each phone line is assigned its

own VT if the host is not a pooled host and no VT assignment

commands were issued. Use the commgr assignvt command to

change the mapping.

assignvt.

VT pooling Dynamic allocation of VTs to Avaya MPS application lines.

In VT pooling, a user-determined number of VTs are assigned to a

group called a VT pool. Generally, the pool is made up of a set of VTs

running a common application on the host computer. The pool is

shared by multiple application lines, and typically the number of lines

is greater than or equal to the number of VTs in the pool.

When an application line requires host access (that is, requires a VT),

the application requests allocation of a VT from the pool. This is done

dynamically. When the VT is no longer required, the VT is freed by

the application and returned to the pool. If one of the VTs in the pool

is down, COMMGR can allocate a different VT from the pool, if one

is available.

VTs from different hosts can be configured into the same VT pool

and multiple pools can be defined. However, no single host VT may

be in more than one pool.

See also VT, application, COMMGR, host, sequential access, non-

sequential access.

VT100 A standard type of host terminal. The Avaya MPS supports

connection to VT100 hosts with the ATTE protocol.
