Marchio: Cisco

L'adattatore del telefono analogico (ATA) consente di collegare un dispositivo analogico, come ad esempio un telefono analogico o un fax, alla propria rete. Il dispositivo connesso può quindi funzionare analogamente ai telefoni IP nella rete.
L’adattatore del telefono analogico (ATA) ha due interfacce:
  • 1 Porta Ethernet 10/100 per la connettività WAN
  • 2 Porte FXS per telefonici analogici o fax
  • Basato su standard SIP
  • Gestione FAX T.38
