Video / Audio Over E1 Multiplexer

Description

It is ensured that any device with E1 interface, such as PBX, Mobile base station, SS7 signaling device and voice post system, can seamlessly connect to E1 video coder & decoder. Also, E1 video coder & decoder can be applied in E1 based communication system, such as: LAN, WAN. MAN and wireless network.

Features

• Video over E1 transparent transmission;
• Optional 1 inverted data channel of RS485/422/232/Manchester;
• Optional 1 positive directional data channel of 485/422/232/Manchester
• Optional 1 inverted audio channel
• Optional 1 positive directional audio channel
• E1 single directional transmition signal at fractions (N*64K), according with G.703/704
• High transmition efficiency, low transmition delays;
• High quality of video signal, video cameras can be controled by PTZ using RS-232/485 interfaces
• Console port for configuration issues;
