6. If these link tests fail to consistently show 90% or greater efficiency in 1X operation or 50
to 60% efficiency in 2X, troubleshoot the link, using the data as follows:
◦ If the downlink is consistently 90% efficient, but the uplink is only 40%, this indicates
trouble for the BHS transmitting to the BHM. Investigate a possible source of
interference near the BHM.
◦ If the uplink is consistently 90% efficient, but the downlink is only 40%, this indicates
trouble for the BHM transmitting to the BHS. Investigate a possible source of
interference near the BHS.
If these link tests consistently show 90% or greater efficiency in 1X operation, or 50 to 60%
efficiency in 2X operation, in both uplink and downlink, continue this procedure.
7. Open the Session Status tab in the Home page of the BHM.
8. Find the Session Count line under the MAC address of the BHS.
9. Check and note the values for Session Count, Reg Count, and Re-Reg Count.
10. Briefly monitor these values, occasionally refreshing this page by clicking another tab and
then the Session Status tab again.
11. If these values are low (for example, 1, 1, and 0, respectively, meaning that the BHS
registered and started a stable session once) and not changing
a. consider the installation successful.
b. monitor these values from the network office over the next several hours and days.
If these values are greater than 1, 1, and 0, or they increase while you are monitoring them,
troubleshoot the link. (For example, recheck jitter as described in Procedure 22: Installing the FSK
SM or recheck link efficiency as described in this procedure, then look for sources of RF
interference or obstructions.)
