DSU DIM Installation
Troubleshooting DSU DIM Installation
Introduction | Some of the potential installation problems are listed below: |
•Improper port connection of the EIM
•Improper telco interface connection
•DSU DIM not connected in DTE configuration
•Processor card jumpers not in HS1 mode
•DSU option software not operational
•DSU port clock source option not correct
•No signal from telco interface
CTP | The following information can be derived from the control terminal to aid in | |
Troubleshooting | troubleshooting. |
|
|
|
|
| Node Statistics | Used to verify that the software is a version which contains |
|
| the DSU option modifications. It also shows if the DSU DIM |
|
| is recognized by the software. |
|
|
|
| Port Statistics | Used to verify that data is being sent without error. Error |
|
| counts may denote an error in clocking mode configuration. |
|
| It also shows if the DSU DIM is recognized by the software. |
|
|
|
| Monitor | Input/output signals can be used to determine if the DSU |
|
| option is in a loopback mode requested by the remote end. |
|
| This would be an explanation for the inability to send data. |
|
| Continuous bipolar violations would also indicate the remote |
|
| system is out of service. |
|
|
|
| DSU Internal | Failure of this loopback mode would indicate that the EIM |
| Loopback | module is not connected. |
