APPENDIX B: DUPLEXER PROGRAMMING

UTILITY

A Prism system can report a Duplexer Mismatch Alarm. This alarm is used to

ensure that the Duplexer is being used with the correct frequency bands.

For example, the PRU/URU supports an 850 Duplexer and an 850 APAC Duplexer.

The 850 Duplexer handles 869-894 MHz, whereas the 850 APAC Duplexer

supports 870-890 MHz. The Host DART can support either band, but if you attempt

to configure a frequency between 869-894 MHz with the 870-890 MHZ Duplexer,

the system will generate a Duplexer Mismatch Alarm.

Previous versions of PRU/URU hardware did not have the Duplexer programmed.

If this is the case, then a Duplexer Mismatch Alarm will be reported. Prism releases

that are 6.0.0.12 or higher include a Duplexer Programming Utility, which allows

field programming of the Duplexer through its Low Noise Amplifier (LNA).

CAUTION! It is recommended that you contact ADC to insure that this is warranted.

The name of the utility is LNAconfig and it is available via a telnet session into the

Remote Unit.

The steps to program through the Duplexer Programming Utility are:

1 Ensure that your laptop Network-Interface Connection (NIC) is configured for

DHCP.

2 Access the Hardware Inventory report for the Host and Remote Unit(s):

a In the System Menu bar, click System Information > Get Information,.

b In the Reports panel Type list, select Hardware Inventory.

c Determine the IP address for the Host and Remote Unit(s).

d Determine the number of the LNA that you want to program; see “RF

Module Capabilities and GUI Representation” on page 21

3 Login to the Host using telnet or ssh.

4 From the Host, login to the Remote Unit using the following command, where

N is the Remote Unit ID (1 - 8):

sshremote N

5 Log on to the Remote Unit as root.

a Type: root

b Enter the following Password: ADCfwu

6 At the prompt, type: LNAconfig
