Transmit-Clock Timing Mode
When you use the external transmit clock on the data-communications side
for G.703 transmit timing, there is complete independence, within the G.703
Codirectional Converter, between the receive and the transmit directions of
transmission. Figure 2-6 shows this timing mode.
Internal-Clock Timing Mode
The Converter’s internal oscillator is usually used as the source for G.703
transmit timing for testing purposes only, but can also be used with systems
that do not have a clock source. Figure 2-7 shows this timing mode.
