Serial Interface

Asynchronous and Synchronous Serial HSSI ISDN

PPP Architecture
A layered architecture is a logical model, design, or blueprint that aids in communication between interconnecting layers. The figure maps the layered architecture of PPP against the Open System Interconnection (OSI) model. PPP and OSI share the same physical layer, but PPP distributes the functions of LCP and NCP differently. At the physical layer, you can configure PPP on a range of interfaces, including:

Asynchronous serial
Synchronous serial
HSSI
ISDN

PPP operates across any DTE/DCE interface (RS-232-C, RS-422, RS-423, or V.35). The only absolute requirement imposed by PPP is a duplex circuit, either dedicated or switched, that can operate in either an asynchronous or synchronous bit-serial mode, transparent to PPP link layer frames. PPP does not impose any restrictions regarding transmission rate other than those imposed by the particular DTE/DCE interface in use.

Most of the work done by PPP is at the data link and network layers by the LCP and NCPs. The LCP sets up the PPP connection and its parameters, the NCPs handle higher layer protocol configurations, and the LCP terminates the PPP connection.PPP Architecture
