Overview
The chassis have 12slots for the voice phone cards. Every card can realize 30POTS (FXO/FXS), 1~4channel G.703 E1 and 1~4 channel 100M Ethernet over fiber transmission, every card can work with the remote standalone 30voice fiber multiplexer by point to point application. The voice phone chassis total capacity is 360 POTS (FXO/FXS).The chassis also can support SNMP management.
