OPERATION

LBI-39128

When no transmitter alarms are received in a status message from the PMU, the Site Controller computer takes the following action:

∙Resumes the practice of using transmitter alarms from the PMU to take transmitter channels out of use for system calls.

∙Continues to assign all transmitters to test calls.

∙Sends the alarm cleared information (transmitter channel number) to the System Manager.

PARAMETERS

CAUTION

Changing parameters not covered in this manual may lead to unsatisfactory operation of the PMU option.

The PMU option parameters covered in this manual are shown in Table 7. The first column lists the parameters. The next three columns represent the three locations where the parameter must be set or may be re-configured. Parameters may go by slightly different names in different locations.

Channel PMU Enable

This parameter set (one bit per channel) is used to enable or disable PMU monitoring of each transmitter channel on a channel-by-channel basis. It is only configurable in the Site Controller computer’s Personality PROMs by the factory, and must be programmed as “Y” (enabled) for each channel you want the PMU to monitor. It is recommended that all 20 channels be enabled (equipped or not).

The factory-configured values for this parameter set in the Site Controller computer’s Personality PROMs is used to configure the Site Controller computer’s Active Configuration during power-up. This parameter set cannot be re-configured in the Site Controller computer’s Active

Configuration by the System Manager. This parameter set is sent to the PMU during the EDACS Configuration Setup, but is not re-configurable there either. This parameter set is used by the PMU to determine which transmitter channels to monitor.

Site PMU Enable

This parameter is used to enable or disable the PMU option as a whole. It is configured in the Site Controller computer’s Personality PROMs by the factory, and can be re-configured in the Site Controller computer’s Active Configuration through a System Manager. If the system is not equipped with a System Manager, this parameter must be programmed as “On” (enabled) in the Personality PROMs by the factory.

The factory-configured value for this parameter in the Site Controller computer’s Personality PROMs is used to initially configure the Site Controller computer’s Active Configuration during power-up. The value of this parameter may then be re-configured in the Site Controller computer’s Active Configuration through a System Manager. This parameter is not sent to (or used by) the PMU. When this parameter is disabled, the Site Controller computer will not send poll messages to the PMU.

PMU Model

This parameter is used to identify the PMU model. It is only configurable in the Site Controller computer’s Personality PROMs by the factory, and must be programmed as “New-8860”.

The factory-configured value for this parameter in the Site Controller computer’s Personality PROMs is used to initially configure the Site Controller computer’s Active Configuration during power-up. The value of this parameter cannot be re-configured in the Site Controller computer’s Active Configuration through a System Manager. The value of this parameter is not sent to (or used by) the PMU. The value of this parameter is used by the Site Controller computer to determine what baud rate to use for communications with the PMU.
