Digital Hybrid PABX System
KY-120DX utilizes TDM/PCM SPC and distribution control technology to enhance system reliability and capacity expansion capability. The free port desigh for trunk and line circuit provides flexible capacity combination.
The system provides powerful network linking ability. It provides analog and digital trunk to connect with PSTN. It also provides wireless CT-2 function to build up a wired and wireless communication network.
KY-120DX is consisting of base cabinet and expansion cabinet. Each cabinet provides 120 free ports of trunk card or analog / digital extension card. The switching power is on base cabinet for AC/DC convertor.
The application of KY-120DX is very powerful. It can link with PC, Modem, Fax machine, Paging system, Radio, PAD, T1/E1 etc. Also it provides tandem function to link with other telephone system and build up a network.
