5.3 Connecting to FXS Interfaces
The device interfaces with the FXS analog telephone equipment (e.g., fax machines,
modems, or telephones) through its 50-pin Telco connector. To connect to the equipment,
you can use your own third-party, MDF connector cable or you can use AudioCodes' MP-
124 FXS Patch Panel (ordered separately from AudioCodes).
Safety Notice
To protect against electrical shock and fire, use a 26 AWG min. wire to connect
analog FXS lines to the 50-pin Telco connector or to the RJ-11 connector.
Note: If SRTP is enabled, the device "borrows" resources (DSPs) for this functionality
from ports 18 through 24, making these ports unavailable for calls.
