Setting the Primary Clock Source

Timing is independent for the two ports on a DMCT1 net module, and for the four

ports on a QMCT1 or QMCT1 w/ DS0A link module. For these modules, you

select the timing source for each port.

Table 7-11

shows the primary source options for timing signals:

Note:

DMCE1 and DMCT1 link modules contain a single clock chip that

provides the timing signals for both ports. Therefore, clock parameters that

you set for the first port apply to the second port on the module.
