Configuring a Demux Card
You can dedicate a packet processing card to function as a demux card. Demux is a generic term for signal
demultiplexing tasks. These are the tasks are responsible for parsing call setup (signaling packets) and distributing the
calls internally. For this reason there almost as many tasks running on a demux card as there are services.

The vpnmgr tasks responsible for each context also run on the demux card. The number of vpnmgr tasks correspond to
the number of contexts. A vpnmgr is responsible for IP address assignment to mobile equipment, IP routing (such as
BGP, OSPF), as well as a variety of associated tasks.

Overview
Designating a packet processing card as a demux card frees up resources for session handling, which has the potential to
increase system throughput. However, there is no increased support in total subscriber capacity due to other system
resource restrictions.
