Application Areas for the CSX

The CSX offers transport and conversion of several service interface onto a copper
network. All this gives a wide bouquet of combinations, which will not all available or
mentioned in the order matrix. Please check with your local arcutronix partner for
your needs and possible options.
The user-side is variable and can support different types of applications, which will be
depicted in more detail below.

Ethernet First Mile

For bridging Ethernet packets directly from the central office side (CO) to the end user
(CPE) over voice-grade copper pairs, the Ethernet community standardized in [IEEE
802.3ah] the EFM PHY 2BASE-TL referring to [ITU-T G.991.2] (192kbps to 5.7Mbps).
