• Creating dispatch communications systems by transmitting E1 streams via interface convertors over IP-network.

• Random network topology: ‘Y”, ring, mixed type.

• Connection of subscriber terminal over two-wires subscriber line via FXS interface.

• Connection of line amplifiers, microphones, studio dispatch equipment over four/six-wires line.

• Connection to higher level PBX via FXO interface.

• Controlling dispatch communications system from common telephone set and from PC connected to the system.
