Updating Default Channel

Setting to Customer Operating

Channel

A non–volatile database containing the default channel and default

power level of the site must be programmed. The default channel is the

customer operating channel for this site. The default power level must

be set to –50 dBm which will be overwritten by the MM/OMCR when

the site comes on–line.

It is imperative that the customer frequency be programmed into this

database. Failure to do so may result in the RF interference to other

RF–emitting devices in the local area whenever the site is powered up.

Table 7-9: Procedure to Update Default Channel Setting to Customer Operating Channel

Step Action

1 Connect the LMF computer terminal to the MMI/LMF connector. Refer to Figure 7-6.

2 If you have not already done so, logout of the BTS and exit the LMF. Wait 10 seconds before

proceeding.

3 Establish an MMI connection session with the BTS. Refer to Table 7-7.

4 Simulate an LMF connection by issuing the sndtype 0xa178 command.

5 Verify that the BTS is in OOS_RAM status by issuing the status command.

6 Enter the op_param –w –50 chan# command. The command parameters are as follows:

–w instructs the BTS to write the values into non–volatile memory.

–50 defaults the power to –50dBm

chan# the customer operating channel (refer to Table 7-43 for 1.9 GHz systems and

Table 7-44 for 800 MHz systems).

If the command is successful, the following response will display:

PASSED: TRX EEPROM updated for power level = –50 (dBm) and channel =

chan#

7 If no additional MMI sessions are required at this time, exit the MMI session and HyperTerminal

connection by selecting File>Exit.

If you are continuing the MMI session, proceed to Table 7-10.
