signals, and provides alarms and events for maintenance.
Table 1 provides the functions and features supported by an FXO12
board.
Table 1 Functions and features supported by an FXO12 board
Function and Feature
Description
Basic functions
Provides 12 FXO ports.
FXO port TX Gain (dB): -16.5 to 13.5, in steps of 0.5.
FXO port RX Gain (dB): -16.5 to 11.0, in steps of 0.5.
Port
External ports: DDN-1 to DDN-12, representing 12 external ports
which always use timeslot 1, with port IDs 1 to 12, respectively.
Internal ports: 2M-1 to 2M-12, representing 12 E1 internal ports
which use timeslots 1-15 and 17-31, with port IDs 65 to 76,
respectively.
Supports the setting of the port working mode to PCM30/PCM30 CRC.
Service processing
Transmits/Receives and processes 12-channel 64 kbit/s signals.
Overhead processing
Supports the setting and query of the V5 and J2 bytes.
Alarms and events
Provides alarms and events for maintenance and fault locating.
Maintenance features
Supports warm and cold resets. The warm reset does not affect
services.
Supports the query of the manufacturing information of the board.
