As shown in the figure:

•

The red path shows the network-bound path for the low-speed TDC data and clock.

The low-speed port receives the clock and data signals from the user equipment, and

transmits it to the transmit data jitter FIFO on the high-speed port. Once out of the

FIFO, the CTP device interleaves the TDC data streams into a single packet flow for

the TDM/TDC bundle.

•

The blue path shows the interface-bound path for the TDC data and clock. The

low-speed port transmits the interface-bound clock and data from the TDM/TDC

bundle to the user equipment.
