Enable MCCs
This procedure configures the MCC and sets the “tx fine adjust”
parameter. The “tx fine adjust” parameter is not a transmit gain setting,
but a timing adjustment that compensates for the processing delay in the
BTS (approximately 3 mS).
Follow the steps outlined in Table 3-17 to enable the MCCs installed in
the SCCP shelves.
NOTE
The MGLI and primary CSM must be downloaded and enabled
(IN–SERVICE ACTIVE), prior to downloading and enabling an
MCC.
