193E TRANSMIT MULTIFRAME TIMING Figure 10
NOTES:
1. Transmit frame and multiframe timing may be established in one of four ways:
2. Channels in which robbed bit signaling is enabled will sample TABCD during the LSB bit time in
3. TLINK is sampled during the F-bit time of odd frames and inserted into the outgoing data stream
a. With TFSYNC tied low, TMSYNC may be pulsed high once every multiframe period to establish
b. TFSYNC may be pulsed every 125 microseconds; pulsing TMSYNC once establishes multiframe
c. TMSYNC and TFSYNC may be continuously pulsed to establish and reinforce frame and
d. If TMSYNC is tied low and TFSYNC is pulsed at frame boundaries, the transmitter will establish
