Subscription Option - Fast Select Acceptance
Description of Option
Is an optional user facility agreed for a period of time. This facility if
subscribed to, authorises the network to transmit to the DTE incoming calls
which request the fast select facility.
DTEs can request the fast select facility on a per call basis by means of
an appropriate facility request.
The fast select facility allows the call request, call connected and clear
packets to contain upto 128 bytes of user data.
A restricted fast select facility restricts the called party to sending a
clear only.
A CCITT 1984 enhancement is that: 'converted calls' (ie non restricted calls
which have exchanged data) can have upto 128 bytes of data in the clear packet.
