Description: Determines the default transmit window size used by this SAP. This value is used only when flow control negotiation (x25SapSbscrFlowCntrlParamNegotiation) is not subscribed to, or when a D-bit call is routed through this SAP.

Range of Values: 1 - 7 for modulo 8

1 - 127 for modulo 128

Default Value: 2

What is x25SapTxWindowSize?

Sets this SAP's default transmit window size (1-7 under modulo 8, or 1-127 under modulo 128; default 2), mirroring x25SapRxWindowSize for the transmit direction -- how many packets this SAP can send before waiting for an acknowledgment. An admin tunes this together with the receive window when optimizing throughput versus buffer usage on an X.25 circuit.

Examples
