V.110/X.30
Transmit Direction
General Features
In transmit direction
– the synchronization pattern for V.110/X.30 frame as shown in Table 1.
– the framing for the different data rates with programmable E-, S-, X-bits
– sending ‘0’ before all frames
is performed automatically.

The E-, S-, X-bits are fed into the data stream by special transmit descriptor (as shown
in Figure 30), they can only change from one 10-octet frame to the next, not within a 10-
octet frame.
The data from the data sections are supposed to come in the form:

1 1 B6 B5 B4 B3 B2 B1 1 1 B12 B11 B10 B9 B8 B7 1 1 B18 B17 B16 B15 B14 B13 1 1 B24 B23 B22 B21 B20 B19
(for Motorola mode),

(for Intel mode).
where for 600 bit/s e.g. B1 to B6 belong to the first 10-octet frame, B7 to B12 belong to
the second 10-octet frame, etc.
