Supports the PPP and IP protocols in protocol mode.ĭoes not support the PPP or IP protocol in flow mode. Supports link layer protocols PPP, FR, and HDLC.Īn asynchronous serial interface supports the RS232 protocol and provides a maximum transmission rate of 115.2 kbit/s.Īn asynchronous serial interface works in protocol or flow mode. The maximum rate of V.24 is 64 kbit/s, and the maximum rate of V.35 is 2.048 Mbit/s. Uses a synchronous serial interface to connect to a WAN.Ī synchronous serial interface can function as a DCE or DTE and supports multiple physical layer protocols, such as V.24, V.35, and X.21. Figure 1.6 shows a typical serial data format. ![]() A serial data format includes four parts: a start bit (1 bit), serial data bits (5, 6, 7 or 8 bits), a parity check bit (1 bit) and stop bits (1 or 1.5 bit). It can work in synchronous or asynchronous mode, and often uses the synchronous mode to connect to a WAN.Ī 2SA card can be installed in a SIC slot of a router. The serial data stream itself contains the information of synchronization and the actual data to be transferred. The 2SA is an enhanced high-speed synchronous/asynchronous serial interface module. The zeros and ones that carry the information that.
