Building Circuits When all of the ports on the QUAD DATA module have been
configured, use the Circuit Manager function of the SCM to build
circuits from the QUAD DATA module to the desired network
interface modules.
Since the Circuit Manager is a function of the SCM, it is covered in
detail in the
SCM User Manual .
A brief discussion of building circuits can be found in the section
“
Building Circuits ” in Chapter 2 of this manual.

Option Description Instructions
PC) The slot number of the application module which will be the
primary clock source for this shelf. This module will provide the
clock signal used to drive the transmit clock circuitry for all
modules in the shelf that use T1 rate clocks.
At the prompt, type the slot
number of the module
selected as the primary clock
source.
PS) Clock source within the module selected for the PC option. Select from the list of ports
available on the module.
PA) Enables or disables fallback to primary clock source after a failed
condition has cleared. If disabled, the SCM never reverts to the
primary clock source until an operator changes this option.
Set to “Yes” if the node is to
revert to a timimg source
which failed, but is now OK.
SC) The slot number of the application module which will be the
secondary clock source for this shelf. If the primary clock source
fails, this module will provide the clock signal used to drive the
transmit clock circuitry for all of the cards in the shelf which use
T1 rate clocks.
At the prompt, type the slot
number of the module
selected as the secondary
clock source.
SS) Clock source within the module selected for the SC option. Select from the list of ports
available on the module.
SA) Enables or disables fallback to secondary clock source after a
failed condition has cleared. If disabled, the SCM never reverts to
the secondary clock source until an operator changes this option.
Set to “Yes” if the node is to
revert to a timimg source
which failed, but is now OK.
TC) The slot number of the application module which will be the
tertiary (third) clock source for this shelf. If both the primary and
secondary clock sources fail, this module will provide the clock
signal used to drive the transmit clock circuitry for all of the cards
in the shelf which use T1 rate clocks.
At the prompt, type the slot
number of the module
selected as the secondary
clock source.
TS) Clock source within the module selected for the TC option. Select from the list of ports
available on the module.
TA) Enables or disables fallback to tertiary clock source after a failed
condition has cleared. If disabled, the SCM never reverts to the
tertiary clock source until an operator changes this option.
Set to “Yes” if the node is to
revert to a timimg source
which failed, but is now OK.
X) Returns to the QUAD DATA Configuration Menu . Exits the Timing Menu.
