Define a transmission group (TG) profile to specify a set of characteristics for a transmission group. The TG profile is not a resource, but describes the TG characteristics of a link.
An adjacent link station (PU) calls a TG profile. When an adjacent link station is activated, VTAM® attempts to locate the TG profile. If the TG profile cannot be found, default values are used for the TG characteristics.
A newer TG profile with the same name as a previously defined TG profile updates the older TG profile. The update does not affect existing connections, but subsequent calls to the updated TG profile receive the new information.
