Service Access Points (NDIS 5.1)

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

A service access point (SAP) identifies the characteristics of incoming calls of interest to a connection-oriented client. By registering a SAP with a call manager or MCM driver, a client indicates that the call manager or MCM driver should notify the client of all incoming calls addressed to that SAP.

A client does not always register a SAP, for example, if it does not handle incoming calls. A client can register multiple SAPs with a call manager or MCM driver.

For more information, see Registering a SAPand Deregistering a SAP.
