Protection
Remote / FXS (subscriber side) interface is protected against power surges and transients occurring
from lightning and electric induction as per ITU-T Rec. K.20 towards line side.
Management Interface
• COM Port (RS232 Serial Port)
• USB Port
• 10/100BaseT Ethernet Port - Each multiplexer may be assigned an IP address and connected to
a LAN / IP network for remote access and management through the 10BaseT Ethernet Port for
out-of-band configuration, management and access
• Telnet
• SSH
• SNMP, V2
• Windows based GUI (Graphical User Interface) for easy configuration, management and access.
