4.4 Remote Access Concentration
In a similar manner to the internet off-load solution outlined above, the MT9088x devices can also be used to
route traffic to a remote resource pool. This allows resources to be centralized, with multiple line cards
accessing the resource pool via the Ethernet switching fabric. A typical application for this is a remote access
concentrator for dial-up modem traffic, and Figure 5 shows an example of this.
The MT90880 on the line card forms the modem data into packets, which are transmitted via the Ethernet
switch to a remote DSP pool. The MT90880 on the remote card converts the packets back to TDM and forwards
them to the DSP pool over the TDM link. The demodulated data is then transmitted back over the packet
network to the router via the MT90880.
This packet-based architecture can be easily extended to support large numbers of modem calls by simply
adding more Ethernet switch interfaces. The architecture can also support ISDN PPP traffic. The DSP pool
strips off the HDLC framing and forwards the packets to the MT90880 for transmission over the IP packet
network.
