1-port HSSI
 interface (1HSSI) 
z
 
2-port HSSI interface (2HSSI
4.11.1 Functions 
The High Speed Serial Interface (HSSI) is connected by the HSSI cable. In the sending 
direction, the IP data packet is encapsulated with PPP or HDLC and sent to the HSSI interface 
line after being transmitted into electrical signals. In the receiving direction, data is 
transmitted into the electrical signals and is processed with the HDLC frame. The device 
extracts the IP data packet in the reverse process and forward the IP data packet.
