Standards exist for DTE Control of DCE using Serial Data
\nInterchange and Start-Stop framing (TIA\/EIA-602, CCIlT V.25bis).
\nWhen user data is not being transferred, DTE commands and DCE
\nresponses are delivered on the same data paths used for user data,
\nsuch as V.24 circuits 103 and 104.<\/p>\n
The above mentioned Standards use out-of-band mechanisms for
\ncontrol while user data is being transferred, such as V.24 circuits
\n108\/2 and 109 for call control and status, and circuits 133 and 106
\nfor flow control. All commands or status messages delivered on
\ncircuits 103 and 104 must be applied while user data transfer is
\nsuspended or terminated.<\/p>\n
This Standard describes procedures for a DTE and DCE to exchange
\ncontrol and status using only the data transfer path. There is need
\nfor In-Band mechanism for DCE control, because Out-of-band
\nmechanisms are not available on all DTE, due to interface
\nrestrictions or DTE system software.<\/p>\n
These procedures depend on the integrity of the data transfer
\npath. It is preferred that the DTE-DCE link should provide some
\nmeans to prevent loss-of-data errors or other corruption of In-
\nBand control information. The specification of means to prevent
\nloss-of-data is beyond the scope of this standard.<\/p>\n
These procedures must be time-independent because
\ninter-character delay time cannot be preserved in DTE containing
\nmulti-tasking software, large character buffers or intermediate
\ndata links (e.g., Local Area Networks).<\/p>\n
This standard defines adaptation of Basic Mode Control
\nProcedures from ISO Standard 2111 for time-invariant In-Band
\nsignaling of the following functions:<\/p>\n
a) Define a mechanism for in-band delivery of control and status
\ninformation between DCE and DTE<\/p>\n
b) Represent V.24 circuits using transparent In-Band
\nCommands.<\/p>\n
c) Poll the corresponding device for its V.24 circuit
\nstatus.<\/p>\n
Using these mechanisms, these In-Band Commands may be used to
\nprovide:<\/p>\n
d) In-Band commands for Flow control (circuits 106 and 133)<\/p>\n
e) Data stream termination (circuit 108\/2 w\/AT&D1
\nsetting)<\/p>\n
f) Terminate session (circuit 108\/2 w\/AT&D2 setting)<\/p>\n
g) Report DCE hook status to DTE<\/p>\n
h) Represent BREAK and Mark-Idle signals be character
\nsequences.<\/p>\n
i) encapsulate ordinary TIA-602 or TIA-615 formatted commands
\nand responses in-Band.<\/p>\n
Other uses of in-band Basic Mode control mechanisms are reserved
\nfor future study.<\/p>\n
This standard also defines semantics for control of these
\nmechanisms (section 8).<\/p>\n","protected":false},"excerpt":{"rendered":"
