Troubleshooting Core Type TDM Channel Modules
Troubleshooting Core Type TDM Channel
Modules
This section will help you resolve issues that can be experienced on TDM core channel
modules. One very important difference between the single application and TDM core
channel modules is that the single application modules require that an application signal
be present before it attempts to establish a network link.
The TDM core channel modules, however, will attempt to establish the network link
immediately upon power on. This leads to slight differences in what you could expect to
see as normal LED states.
The LEDs are located on the faceplate of every TDM core channel module. This section
