4.3 Internet Off-load
Internet off-load is a means of relieving the congestion in circuit-switching equipment caused by excessive dial-up
modem traffic with long call duration. Modem traffic is directed to the packet-switched network, bypassing traditional
voice switches. This reduces the capacity of the required circuit switches, and hence the cost of a typical
installation.
The MT90880 is an ideal device for implementing internet off-load, allowing voice traffic to be routed through the
TDM switch to the voice switching infrastructure, and modem traffic to be sent over the packet network to the
Remote Access Concentrator (Figure 4). The RAC could be local or remote, with traffic routed over the data
networks.
