•Remote alarm

•UA1

Aseven-day error history of the E1 interfaces and radio link is also provided. Fifteen-minute histories are provided for the most recent 24 hours of operation.

The status of the microwave link can also be monitored from the management system. The transmitter power setting as well as an indication of the received microwave signal level are provided.

Alarm Contacts

Two classes of alarm, MAJOR and MINOR, are provided. A MAJOR alarm is signaled if, for any reason, the microwave path is not operational. A MINOR alarm is signaled when the data path is operating, but impaired. A minor alarm will be activated when an alarm is sensed on the E1 interfaces or when the received RF signal level falls below approximately -80 dBm. Both normally-open and normally-closed contacts are provided for each alarm class. Access is provided by a six-position terminal strip on the back of the baseband processor.

IF Signal

The Type N Connector provides the interface point between the baseband processor and the radio frequency converter (RFC). This connection provides the signal, power, and configuration information to the RFC. A coaxial cable (ADTRAN part number 3125RF027 is provided for connecting the BBP to the RFC for the rackmount model. Cable for connecting the BBP to a mastmount RFC must be provided by the customer after the length of the cable has been determined.

Power

The unit receives power via one of two connectors. Power for the entire system is provided by these interfaces. The 3 pin circular DIN connector is provided to connect an ADTRAN supplied desktop AC adapter providing 48 volts DC. The three-pin terminal block allows the connection of any DC power source providing between 21 and 60 volts DC. The power consumption of the entire system is approximately 30 watts.

Controls and Indicators

The system may be configured via the front panel, which is accessible behind a drop-down panel on the right half of the BBP. The front panel is illustrated in Figures 1-6and 1-7.
