Troubleshooting Access Type TDM Channel Modules
2TCA-PCN-1G3+2G5
This subsection will help you resolve issues that can be experienced on 2TCA-PCN-1G3+2G5 modules. It
assumes that all measurements for the C1/R, C1/T, C2/R, C2/T, N/R West, N/R East and N/T West, N/T East
interfaces are within ADVA Optical Networking specifications and that you have verified that the application
wavelength is the same as the wavelength for the client pluggable transceiver interface. If not, refer to “Finding
Your Problem - Follow the Light” on p.53.
CAUTION
Follow all the instructions precisely. If you do not supply the specified attenuation on given
steps, you could destroy the module being tested. As soon as the near-end and the far-end
2TCA-PCN-1G3+2G5 modules in a link are synchronized, the network link is up. The network
interface LEDs light up solid green or green blinking depending on the configured transmission
ode: Multiplexer NE Only, Multiplexer NW Only, or Multiplexer NE & NW.
Note
Before you start with troubleshooting, ensure that the current firmware package is installed on
the 2TCA-PCN-1G3+2G5 module. For details on updating module firmware, refer to “Updating
the NE Software Release” on p.617 and “Performing Other Software Update Actions” on p.628.
Note
Before you start with troubleshooting, ensure that the admin status on the affected module is
configured to “Maintenance”.
Note
The near-end and far-end modules must be provisioned to the same transmission mode to
guarantee proper operation.
Note
The module supports configuring ‘disparity correction’. It is set to “enabled” by default. For more
information about this parameter, refer to the Management Data Guide.
CAUTION
The use of pluggable transceivers other than those approved by ADVA Optical Networking will
result in loss of safety approval for the FSP 3000R7. Pluggable transceivers not approved by
ADVA Optical Networking will not function properly. Depending on the channel module type, Rx
and Tx of the affected interfaces may be disabled automatically or not. Only approved pluggable
transceivers will guarantee the behavior in conjunction with the channel module as specified.
Note
If your module has an LED status that is not represented in Table 38 on p.240, please contact
your ADVA Optical Networking Technical Services Representative.
The steps in this subsection may need to be completed on both sides of the link. Please follow the
troubleshooting steps in Table 38 on p.240 based upon the states of the LEDs.
