Voice Module
DONJIN voice modules are installed on DONJIN analog trunk voice boards. They include the trunk module, user module, trunk/user module, Hiz recording module, magneto module, E/M control module, 2-channel voice module, and 4-channel voice module. Various modules can be used for various functions. Under the DBDK SDK, different kinds of modules can be installed on a same mother board.
Name | Type | SDK | Image | Function | |
Voice Module | 2-channel trunk module | M2T | DBDK/NADK | It is installed on a motherboard of an analog trunk voice processing board for accessing the foreign exchange office (FXO) interface. It can process 2 analog trunk channels simultaneously. | |
2-channel user module | M2U | DBDK/NADK | It is installed on a motherboard of an analog trunk voice processing board for accessing the foreign exchange subscriber (FXS). It can process 2 user channels simultaneously. Power-3 need be used to provide the feed and ring power. | ||
2-channel recording module | M2R | DBDK | It is installed on an analog interface recording processing board for wire tapping recording. It can process 2 recording channels simultaneously, and can detect voltages adjustably. | ||
Trunk/User module | MTU | DBDK | It is installed on a motherboard of an analog trunk voice processing board for connecting to the FXO and FXS, with each module processing one FXO interface channel and one FXS interface channel. Power-3 need be used to provide the feed and ring power. | ||
2-channel magnet module | MCS | DBDK | It is installed on a motherboard of an analog trunk voice processing board, which can be considered as 2-channel magnet phones. When the magnet channel is used for inbound calls, it can be considered as a trunk channel; while the channel is used for outbound calls, it can be considered as a user channel. Power-3 need be used to provide the feed and ring power during the working. | ||
EM control module | MEM | DBDK | It is installed on a motherboard of an analog trunk voice processing board and can process two 4-pin E/M trunk channels or E and M signals of 2-pin E/M trunk. | ||
2-channel E/M voice module | M2VOC | DBDK/NADK | It is installed on a motherboard of an analog trunk voice processing board and can process two 2-pin E/M trunk voice channels. | ||
4-channel E/M voice module | M4VOC | DBDK/NADK | It is installed on a motherboard of an analog trunk voice processing board and can process one 4-pin E/M trunk voice channels. |
