CELLX box 17.1/002

This chapter describes the general features of the CELLX Box and the main features
for VoIP, telephony, and mobile. 

The CELLX Box is a media converter that facilitates the connection of voice over IP (VoIP) with
mobile networks. The connection to telephone equipment using FXS is optional. It converts
line-based transmission on mobile side to packet-based transmission in the IP network and
vice versa. Incoming traffic arrives at one CELLX Box, which routes the calls according to their
destination and attributes. 

Table 1.1

 list the main variants of the CELLX Box.

The CELLX Box contains two Gigabyte Ethernet interfaces to the IP network.
