Network Timing
The network is the source of timing. The received data clocking is
looped back to the network, where it is used to determine the
transmission timing. This option is also referred to as looped timed
as the transmission clock is derived from the received clock. See
Figure 5-2.
Figure 5-2. Network Timed Clock Source
The clocking option selected always designates the clock source
for transmission. Clocking necessary for receiving data is always
recovered from incoming data.
