Primary Send Pacing (PSNDPAC)

Use Primary Send Pacing to perform pacing between the PLU and one of the following:

• The boundary function NCP for the SLU (session with link attached peripheral node)
• Another APPL (APPL‑to‑APPL session)
• The VTAM boundary function (cross‑domain session with locally attached node)

Pacing is used for OUTBOUND (PLU‑to‑SLU) traffic only. The value in the logmode PSNDPAC field overrides all other Primary Send pacing parameters.

Coding 0 for the PSNDPAC field in the logmode indicates that the Primary Send Pacing value will be governed by the VPACING value coded on the LU definition. The SLU's VPACING value in the APPL definition will be used if this is an APPL‑to‑APPL session. If you do not code VPACING and the PSNDPAC value is set to 0 in the logmode, the default VPACING value is 2 for a LU and 0 for an APPL.
