Description

This Standard specifies the electrical characteristics of the
unbalanced voltage digital interface circuit, normally implemented
in integrated circuit .technology, that may be employed when
specified for the interchange of serial binary signals between Data
Terminal Equipment (DTE) and Data Circuit-Terminating Equipment
(DCE) or in any point-to-point interconnection of serial binary
signals between digital equipment.

This Standard is compatible with ITU-T (Formerly CCilT)
Recommendation V.l O.

The interface circuit includes a generator connected by a
interconnecting cable to a load consisting of a receiver or
receivers. The electrical characteristics of the circuit are
specified in terms of required voltage, current, and resistance
values obtained from direct measurements of the generator and
receiver components at the interface points. The logic function of
the generator and the receiver is not defined by this Standard, as
it is application dependent. The requirements for signal wave
shaping, generally necessary to reduce unbalanced circuit near-end
crosstalk to adjacent circuits, are also described. The receiver
specification for the unbalanced interface is identical to that
specified for the balanced interface circuit in TINEIA-422-B.
Minimum performance requirements for the interconnecting cable are
furnished. Guidance is given in Annex A.l with respect to
limitations on data signaling rate imposed by the parameters of the
cable length and generation of near-end crosstalk.

The parameter values specified for the unbalanced generator and
load components of the interface are designed such that unbalanced
interface circuits may be used within the same interconnection as
balanced interface circuits specified by TINEIA-422-B. For example,
the balanced circuits may be used for data and timing while the
unbalanced circuits may be used for low speed control functions. In
addition, interoperation may be possible under certain conditions
with generators and receivers of other digital interface standards
such as EIWIA-232-E (see Annex B Section B.l).

It is intended that this Standard will be referenced by other
standards that specify the complete DTE/DCE interface (Le.,
connector, pin .assignments, function) for applications where the
electrical characteristics of an unbalanced voltage digital
interface circuit are required. This Standard does not specify
other characteristics of the DTE/DCE interface (such as signal
quality and timing, etc.) essential for proper operation across the
interface.

When this Standard is referenced by other standards or
specifications, it should be noted that certain options are
available. The preparer of those referencing standards and
specifications must determine and specify those optional features
which are required for that application.
