MediaPack Analog Gateways 27 MP-124
Hardware Installation Manual 5. Cabling the Device
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.
