Product Part Number: 251L295 (2 port)
Product Part Number: 251L290 (8 port)
The AMTELCO FXO to VoIP Gateway Appliances provide a self contained Asterisk® LTS switching environment with multiple integrated FXO (Loop Start) analog interfaces. Bidirectional connection of the FXO interfaces to a corresponding SIP channel on the Ethernet interface is implemented through standard Asterisk dialplan entries. Standard FXO signaling protocols include the ability to seize the line, detect the presence or absence of loop current, and detect ringing signals with a variety of frequencies and cadences. Port timing and impedance characteristics can be set to adapt to different national standards.
Additionally, each port on the appliance can be configured for use in a high-impedance mode. This mode provides the ability to monitor an FXO interface without significantly affecting other devices on the interface.
The gateway unit includes an internal web server allowing user-programmable FXO port settings and arrangement of the Asterisk dialplan through a custom designed web interface (accessible through any standard web browser). Additional connectivity to the operating system for administration of the Linux environment or Asterisk utilities is available through SSH.
The AMTELCO Gateway Appliances can be powered from the network using Power over Ethernet (PoE), or using an included DC wall adapter. An integrated fan provides for internal component cooling, and an external power switch is included for controlled shutdown and startup of the appliance.
