Overhead Functions
The overhead functions consist of a controller, front panel, two RS232
communication interfaces (terminal and network management), and a
power supply.
The controller function is performed by a microprocessor on the main
board. The controller collects T1 statistics. It also processes T1 alarms and
performance monitoring information, as well as supporting unit
conÞguration, test and maintenance activities. Finally the Controller block
supports the front panel display, terminal port, and SNMP port interfaces.
The front panel consists of a 16 character vacuum ßuorescent display, 4-key
keypad and LEDs. This panel can be used to provision the unit, run
diagnostic tests, or gain access to performance statistics.
The serial ports are RS-232C compatible ports with one port supporting a
menu driven ASCII terminal interface, and the other port providing access
to the built-in SNMP agent functionality.
