xDSL MODEMS - TRANSMISSION OVER COPPER

CXR offers a comprehensive selection of DSL modems to meet your needs.

High Speed Ethernet topology

Ethernet is extended over existing copper in

Symmetrical or asymmetrical transmission form with both varying rates and distances.

CXR Anderson Jacobson utilizes the following technologies:

G.SHDSL et MSDSL modems and switches with a symmetrical rate from 2.3 to 13.8 Mbps at a distance up to 13km (8.08 miles).

VDSL modems and switches with a symmetrical rate from 2.5Mbps up to 5.0 Mbps at 1.9km (1.18 miles).

The transmission of WAN topology

This is used for the transport of symmetrical voice, data, video (E1/T1, ISDN PRI/BRI, V35/X21/RS-530)

G.SHDSL modems with TC-PAM coding are used with Telco and PBX interconnections for voice and data installations. This technology is less sensitive to noise and crosstalk and can reach longer distances.

MSDSL modems with CAP coding are used in campus environments and have a maximum speed of 4.6Mbps overpoorquality copper.

The Multipoint transmission of Ethernet and RS-xxx at a low rate over long distance

This is used for industrial remote control, multipoint and RTU applications

Multi-G.SHDSL modem/switch distributes Ethernet and asynchronous flow in BUS or RING topology over one or two copper pairs

Base Band Modems transporting low speed synchronous or asynchronous links in "point to point" or "multipoint" applications.
