Chapter 2: Unit Installation
Identifying Communication Ports
The Asterisk Appliance unit consists of up to eight RJ11 analog ports
which can be configured as either FXO or FXS ports, depending on the
type of modules installed in the Asterisk Appliance model. These ports
provide 32ms of analog port echo cancellation. The unit is rated for a total
of 8 REN across all FXS ports. Each individual port is rated for up to 3
REN @ 1500ft (450m).
Four 10/100BaseT LAN ports and one 10/100BaseT WAN port provide
the functionality to connect to the local network as well as allowing the
Asterisk Appliance to act as a router. All the Ethernet ports support auto-
MDI/MDX.
See Figure 2 on page 22 to locate the ports and their corresponding LEDs.
Understanding the LEDs
There are 15 LEDs on the front panel of the Asterisk Appliance. The eight
LEDs corresponding to the analog ports on the rear panel, indicate the
type of interface installed. The definition of each LED and its color
representation is explained in Table 1.
