Description
This model is the point-to-point optical transport equipment based on self copyright IC. It is single board structure and provided with complete alarming function. It offers 1~30 voice (FXS/FXO) channels. It can realize SNMP management on stand-alone device via built-in SNMP module. The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.
Features
nBase on self copyright IC.
