Voice Over E1

4Voices + 1FE + 4RS232/485/422 over E1 PCM Mux

Overview
This equipment provides an E1 access1~4 channel voice outputssupport 4U rack. 1channel Ethernet (bandwidth 2M) +2*channel RS232/422/485/Dry contact. 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.
