Voice Over E1

E1-16Voice + 4FE + 4RS232 PCM Multiplexer

This equipment provides an E1 access1~16 channel voice outputs4channel data(RS232/422/485)and 4*10/100M ethernet optional(bandwith 2M) The electricity part is digital circuit. The superiority of this product is reliable work and stable with high integration and lower energy consumption. Small size for easy install and maintenance. Most clients of telecom operators rent E1 line for ethernet networking while this equipment could supply more telephone lines on E1 and free call between head office and branch.
