Classified Local Area Network (C-LAN) is a packet port circuit pack for Communication Manager. C-LAN provides TCP/IP connectivity to various accessories for applications. C-LAN has one 10BaseT or 100BaseT Ethernet connection and up to 16 DS0 physical interfaces for Point-to-Point Protocol (PPP) connections. You can integrate two modems to provide a remote PPP connectivity over an analog circuit. You can add multiple C-LAN circuit packs to a system to increase the TCP/IP capacity.
Note Use C-LAN circuit packs that have the ability to handle the maximum number of active endpoints, for example, TN799C V4, TN799DP, or a later version. If you are using earlier versions, the system may encounter difficulties if the C-LAN circuit pack reaches the maximum number of active endpoints.
