Terminal Adapter Configuration Example

The following example configures a Cisco AS5200 access server to enable PCs fitted with internal or external terminal adapters to dial in to an IP network. The terminal adapter configuration is set up for asynchronous to synchronous PPP conversion. In some cases, PPP authentication must be set up for the Password Authentication Protocol (PAP). Some terminal adapters only support PAP authentication.
