APPN transmission group profile definitions

A transmission group profile defines the following set of characteristics for a transmission group:

Capacity (effective capacity of the link that comprises the TG, in either kilobits or megabits per second)
Cost-per-byte-transmitted (on a scale of 0 to 255)
Cost-per-unit-of-time (on a scale of 0 to 255)
Maximum propagation delay of the link (maximum time needed for a signal to travel from one end of the link to the other)
Security (the security level of the transmission group)

When an adjacent link station (PU) is activated, VTAM® attempts to locate the TG profile specified by the TGP operand of its PU definition statement.

For more information about transmission group profiles, see the z/OS Communications Server: SNA Resource Definition Reference.
