Quidway® AR 28 Router POS/CPOS Interface Module

Overview

The AR28 router can provide 1-port POS module and 1-port CPOS module respectively.

1CPOS is the abbreviation of 1-port channelized SDH/SONET interface card. Where, C indicates

Channelized and POS indicates Packet Over SDH/SONET. 1CPOS supports one STM-1/OC3

multi-channel interface card and the 155.52 Mbps communication rate.

The 1CPOS interface card falls into RT-1CPOS (E) and RT-1CPOS (T). Where, RT-1CPOS (E)

interface card supports the E1 mode and RT-1CPOS (T) interface card supports T1 mode.

1POS is the abbreviation of 1-port SDH/SONET. Where, POS indicates Packet Over SDH/Sonet

and 1POS interface transmission rate is STM-1/OC-3 (155.52Mbit/s).

1POS data link layer can use PPP, frame relay and HDLC protocol. On the network layer the IP

protocol is used. The 1POS interface is to transfer data packet on SONET/SDH directly.
