L2TP LNS Session and Tunnel Capacities
The system is capable of supporting L2TP tunnels for all subscriber sessions or on a session-by-session basis.
Each L2TP tunnel can facilitate one or more subscriber sessions. The number of supported L2TP sessions and tunnels
corresponds to the number of active Packet Accelerator Cards (PACs) or Packet Services Cards (PSCs) available to the
system.
