Analog Interface Board PFBA30X
The analog interface board is installed in the service slots of Keygoe3000 chassis, and each board provides 30 analog channels. By inserting DONJIN M2T, M2U, MTU, M2R, MCS, MEM, M2VOC, and M4VOC, you can configure the loop trunk interface, user trunk interface, high-impedance interface, and other special analog interface. When the module M2U, MTU, or MCS is configured, the feeding and ringing power is required.
The analog interface board could detect the voltage to improve the system management efficiency.
Type | Appearance | Function |
M2T | The analog trunk module, used for accessing the foreign exchange office (FXO) interface, with 2 trunk channels for each module | |
M2U | The analog user module, used for accessing the foreign exchange subscriber (FXS), with 2 user trunk interfaces for each module, requiring the feed power and ring power. | |
MTU | The analog trunk user module, used for connecting to the FXO and FXS, with each module processing one FXO interface channel and one FXS interface channel, requiring the feed power and ring power. It can be used as the emergency exit during power-off. | |
M2R | The recording module, together with the analog interface board and digital phone recording board, is used to record calls on an analog phone. Each module can process 2 recording channels. | |
MCS | Magneto module, used as a magneto phone, each module has 2 channels, requiring the feed power and ring power. | |
MEM | The EM trunk control module is used to convert the telecom interfaces between devices. By the combinations from E lines and M lines, the forward signals and backward signals can be transmitted. It requires feed power. | |
M2VOC | The EM 2-line voice module is used to convert the telecom interfaces between devices. By the combinations from E lines and M lines, the forward signals and backward signals can be transmitted. 2-line E/M trunk (for 4 lines, they are 2-line voice, E line, and M line). | |
M4VOC | The EM 4-line voice module is used to convert the telecom interfaces between devices. By the combinations from E lines and M lines, the forward signals and backward signals can be transmitted. 4-line E/M trunk (for 6 lines, they are 2-line for receiving voice, 2-line for sending voice, E line, and M line). |
