Setting the Clock Source

Each narrow ProCurve Secure Router module can have only one clock source.
For T1 + DSX-1 modules, you configure the clock source on the line that is
used for data. By default, the clock source for this T1 interface is line. With
this setting, the T1 interface takes its timing from the public carrier's equip-
ment. The DSX-1 interface, in turn, takes its clock from the T1 interface.
Clock source is set to through
Channels 1-12 are "nailed" to the
T1 interface.
Channels 13-24 are allocated to
the DSX-1 interface.
