Using CDMA LMF 68P09255A61-4 Logging into a BTS NOTE Be sure that the correct bts-#.cdf and cbsc-#.cdf file is used for the BTS. These should be the CDF files that are provided for the BTS by the CBSC. Failure to use the correct CDF files can result in invalid optimization. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site. Logging into a BTS establishes a communications link between the BTS and the CDMA LMF.
