A TE may start transmission of a layer-2 frame first when a certain number of
consecutive 1s has been received on the echo channel. This number is fixed to 8 in
priority class 1 and to 10 in priority class 2 for the normal level of priority; for the lower
level of priority the number is increased by 1 in each priority class, i.e. 9 for class 1 and
11 for class 2.
A TE, when in the active condition, is monitoring the D echo channel, counting the
number of consecutive binary 1s. If a 0 bit is detected, the TE restarts counting the
number of consecutive binary 1s. If the required number of 1s according to the actual
level of priority has been detected, the TE may start transmission of an HDLC frame. If
a collision occurs, the TE immediately shall cease transmission, return to the D-channel
monitoring state, and send 1s over the D-channel.
