Identifying Communication Ports
The Asterisk Appliance 50 unit consists of up to eight RJ11 analog ports
which are configured as FXO or FXS ports depending on the Asterisk
Appliance 50 model. These ports provide 32ms (Hardware Revisions B)
or 128ms (Hardware Revisions C) 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 50 to act as a router. All the Ethernet ports support
auto-MDI-X.
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 50. 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.
