A comprehensive solution by several interfaces
Features of the solution:
Digital four-wire line of the host in teleconference system is connected with sound console of the conference’s meeting room, and digital junction E1 interface and loop junction interface are connected to private network interchanger of enterprises and public institutions or digital junction E1 and telephone digital subscriber lines of telecommunications office’s local call interchangers, respectively. The interchanger assigns an access number (or route number) to the teleconference system. The conference room and host stay in a state of direct connection and do not need make dialing. Other parallel sessions attend the conference by dialing teleconference access numbers (out number), teleconference numbers (loop trunk) and passwords.
Application of the solution:
The solution adopts several interfaces like digital junction E1, two-wire loop trunk and digital four-wire interface to access TCS that uses master clock mode. Thus, its reliability is improved largely. It is quite appropriate for interactive teleconferences that have system administrative telephone network and participation of users from parallel sessions outside administrative network simultaneously. Typical users include Xinjiang Changji Electric Power Bureau etc.
