A seven-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 1-6 and 1-7.
