The basic characteristics
The adapter forms standard pressure for a telephone set on a two-wire line:
Dc voltage at the put tube =60V (±5V);
Ac voltage индукторного a call ~70. 120V:
Current in a line during conversation 30. 35mА.
Installation without the soldering.
The device does not consume a current from the block Ava in a mode of expectation and does not break modes of entering and proceeding communication.
The improved characteristics of a sound transmission (only for АА28).
