4.9 Synchronous serial port module
There is one type of synchronous serial interface module for the Secure Router 8012: the
4-port enhanced high-speed synchronous serial interface card (4SAE).
4.9.1 Functions
The 4SAE supports the synchronous working mode. Its main function is to receive, send, and
process the synchronous serial data flow and to support the modes of Data Terminal
Equipment (DTE) and Data Circuit-terminating Equipment (DCE).
The functions of the interface are as follows:
z
supports local loopback
z
automatically identifies the V.35 and V.24 cables
z
supports various link layer protocols, such as PPP, Frame Relay, and HDLC
