Diagnosing the External TPIU
Table 6-4 shows the function of the LED indicators on the front panel of the
standalone TPIU.
Diagnosing the Retimer Module
The Retimer module is transparent to framing errors, bipolar violations, and data
errors; these errors are passed through to the downstream Network Element. If an
incorrect signal type is inserted into the Retimer module (for example, if an E1
signal is connected into a T1 Retimer), the module may report a large slip count.
Verify that the proper signal is inserted into the Retimer module.
Note: If the replacement IMC has a different software load than the
original IMC, you cannot log in to the TimeProvider using the existing
username and password. You must create a new username and
password using the ENT-USER-SECU command.
