Voice Over E1

30Voice E1 Multiplexer (CAS signaling)

Overview
This device is a kind of developed transmission equipment based on our company E1 line transmission the special-use VLSI. It has alarm function.1~30channel voice optional16 time slot  signaling and CAS(channel associated signaling) can communicate with each other. The working is reliable stable and low power consumption high integration small size ease of installation and maintenance.
