Subnetwork rerouting not supported: An SSCP received a session services request—CDINIT, INIT_OTHER_CD, NOTIFY (vector key=X'01'), or DSRLST—from an SSCP in its subnetwork that, if rerouted, would not cross a subnetwork boundary. The SSCP does not support rerouting within a subnetwork.
VTAM® Information: When VTAM receives this sense code for a session initiation, it continues searching through the adjacent SSCP table until the destination LU is found or routing is exhausted.
