Chapter 4 l RN commissioning
Performing Loopback tests
4-18 910136 Rev01.00 Standard July 2007
For example, the following command sets the second T1 or E1 backhaul to internal
loopback mode: >ipBts-XXX_SC>mmb f500010a 04
2. If the backhaul links are Ethernet, enter the following CLI command:
>ipBts-XXX_SC>poke874 fenet1 13 803c
3. Run the internal backhaul test on the interface(s) you have set to internal loopback mode
with the following CLI command:
4. Enter the following command to start the loopback test:
>ipBts-XXX_SC>commsend <number of tests> <ports>
Where:
•<number of tests> specifies the number times each port is to be tested. The valid
range is between (0 – 100000).
•<ports> specifies the names of the ports to be tested. See Table 4-6.
For example, the following command would start the loopback test for a system with two
E1 backhaul links: >ipBts-XXX_SC>commsend 10 T1 T2
5. Evaluate the results.
After the test is complete, the following data table displays for each backhaul tested.
