What is x25SapSbscrFastSelect?

Controls whether this SAP subscribes to the Fast Select facility on outgoing calls: subscribed (true, the default) permits up to 128 bytes of user data in Call Request/Accept/Clear packets and only routes such calls if the destination side subscribes to Fast Select Acceptance; not subscribed (false) limits Call Request/Accept user data to 16 bytes and refuses calls carrying the facility. An admin enables Fast Select when applications need to exchange a larger burst of data during call setup itself (e.g. transaction-style traffic), per X.25 Section 6.16.
