Catégorie : Étiquettes : ,

Product Description

TSM-30E transmits 30 channels of voice over coaxial cable or twisted pairs. With all FXO/FXS modules soldered to the main board, this model is more cost-effective than modular ones and also has a more stable performance.

Functional Properties

   based on proprietary integrated circuits;

   alarm status can be monitored on the end;

   E1 interface complies with G.703 all-digital clock recovery and smooth phase-locked technology;

   support FXO voice port FXS ports and ports EM2 / 4 audio interface FXO port and PBX docking port  and the user is connected to FXS telephone;

   30 road voice access support caller ID function and reverse polarity billing functions;

   Support Telephone Number mutual function of each site;

   E1 signal can be detected as a barrier to the end device is lost or shut E1;

   multiple power mode options: AC220V DC-48V / DC24V etc;
