D.2 External clock requirements
WINLink 1000 system assumes that all external equipments connected
to a single site use the same transmit clock. In the picture above, E1 –
1 in (site A) and E1 – 2 in (site A) must use the same clock. E1 – 1 in
(site B) and E1 – 2 in (site B) must also use the same clock, but this
clock can be a different clock that used in site A. The system
automatically selects a specific trunk for clocking according to the
rules described below.
