Troubleshooting Page 169 of 206Meridian Companion Installation and Maintenance Guide8. Replace the Administration Terminal with a working AdministrationTerminal. If the problem persists (see “Troubleshooting” on page 163).Note: You should find between 18 and 21 V DC across the telephone wireswhen the Administration Terminal is disconnected.Troubleshooting a Base Station1. Verify that the green LED (the power indicator) is on.2.

If the red LED continues to flash, then oneof the following problems may exist:• The Base Station is not connected to the Controller or line card.• The wiring to the Base Station is not correct. Check for open circuitsthrough the secondary protectors for applications with exposed wiring.• The two-way DC loop resistance of the power pair(s) between the RPIand the Base Station exceeds 100 Ω. Measure the loop resistance with anohmmeter. If the resistance exceeds 100 Ω, install a second power pair.• The Base Station or RPI is faulty.If the red LED is flashing on multiple Base Stations, one of the followingproblems may exist:• The CMCC, CMRC, or CMBC card associated with the Base Stationsmay not be in place.• The MDF cable may have been removed.4. Verify that the power cord of the RPI is properly connected to a workingAC outlet. If the Base Station is powered locally, verify that the power
