1 POS Interface Configuration
About This Chapter
The Packet over SONET/SDH (POS) technology is applied to MAN and WAN.
1.1 Overview of POS and CPOS Interfaces
This section describes concepts of SONET and SDH, channelization and non-channelization,
and frame structure of SDH.
1.2 POS Interface Features Supported by the S9300
Packet over SONET/SDH (POS) maps packets of variable lengths into the payload of SONET/
SDH signals. POS transmits packets at the physical layer of SONET/SDH, which provides a
high speed, reliable, and point-to-point data connection.
1.3 Configuring POS Interfaces
You can configure the link layer protocol, clock mode, overhead byte, frame format, and CRC
for POS interfaces.
1.4 Maintaining POS Interface Configuration
You can enable the loopback function to detect whether an interface runs properly and clear
interface statistics to maintain the POS interface.
1.5 Configuration Examples
This section describes details about POS interfaces, including applicable scenarios and
configuration commands.
