7/8 – Clocking
The Clocking option selects the source for the data transmission timing and sychronization clock (received data is clocked
from the received signal).
Network timing loops the received data clocking back to the network for transmission clocking. This setting will normally
be used over links from a service provider.
Internal clocking uses the oscillator on the T1/E1 interface of this router to provide the clock signal for transmitted data.
This setting could be used on a private line end to end link, with one end providing the clocking (the other end would be
set to network clocking).

[network]
