Chapter 4
Core Type Channel Modules
This chapter addresses all core type channel modules available at the publication date of
this manual.
This chapter contains these sections:
“Troubleshooting Core Type TDM Channel Modules” on p.96, which addresses LED
indicators and troubleshooting guidelines for TDM core channel modules.
“Troubleshooting Core Type WDM Channel Modules” on p.165, which addresses LED
indicators and troubleshooting guidelines for WDM core channel modules.
Note
A green client/network port LED indicates no conditions are present at
the port that require troubleshooting this port, to resolve fault(s)
associated with the transported signal(s). Conditions informing about
consequent actions (e.g. LKDO-OFF) are not indicated by these LEDs,
since they require troubleshooting the fault upstream (at another port of
the same module or a remote module).
