.SS "Connection Data Transfer"
.PP
The following primitives provider for the transfer of data with a connection
oriented transport service provider.
The transport service provider provides the following connection mode data
transfer services:
.PP
.B Data Transfer Service
The connection mode data transfer service provides the ability to transfer
normal connection mode data between the transport services user and the
transport service provider.  It also provides the ability to exchange data in
transport inteface data units smaller that the overall transport service data
unit.
The connection mode data transfer service uses the following primitives:
.IP \(em \w'\(em\(em'u
.BR T_DATA_REQ (7):
Requests the transmission of data on a transport connection.
.IP \(em \w'\(em\(em'u
.BR T_DATA_IND (7):
Provides indication of the reception of data on a transport connection.
.PP
.B Expedited Data Transfer Service
The connection mode data transfer service provides the ability to transfer
expedited connection mode data between the transport services user and the
transport service provider.  It also provides the ability to exchange data in
transport inteface data units smaller that the overall expedited transport
service data unit.
The connection mode data transfer service uses the following primitives:
.IP \(em \w'\(em\(em'u
