INFORMATION
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.
