Voice Over E1

E1-16PCM Multiplexer (desktop type)

Overview
This device provides 1~16channel voice outputssupport 4U rack plug-in. The electricity part is full 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.
