High Rate Ethernet G.SHDSL or MSDSL modems
These modems use one to four copper pairs to transmit with adaptative rates to reach higher speeds or distances up to 13km (8.08 miles).
The CXR MSDSL modem utilises CAP technology. It produces 4.6Mbps over a single copper pair or 144Kbps up to 13km (8.08 miles) with AWG 19 copper. This coding is very robust and can work over poor quality lines. This technology is also compatible with analog voice.
The CXR G.SHDSL TC/PAM modem employs more recent technology. This technology is utilized by the Telco in the same copper facilities as E1-MIC or ISDN and analog voice lines. It adapts better for longer distance than MSDSL transmission but is not compatible with the analog voice spectrum.
For Ethernet to Ethernet connections, or LAN extensions, CXR suggests:
CopperLAN & SpeederLAN for Point to Point connections
CopperLAN and SpeederLAN can be loaded with MSDSL (CAP) or G.SHDSL (TC-PAM16) which are software selectable by the customer.
When the CopperLAN is running the CAP coding it's compatible with the MD20BT/MD2HUB.
CopperLAN transmits up to 4.6Mbps over one copper pair
SpeederLAN transmits up to 13.8Mbps over 3 copper pairs
SWM-24GS-TTX / QX3440 concentrators of Ethernet over G.SHDSL
The SWM-24GS-2TTX is a G.SHDSL switch that can terminate 24 2w CopperLANs or 12 4w MD44FT.
The QX3440 can be equipped with a G.SHDSL card and router card to terminate up to 48 CopperLAN modems.
CopperWAY Ethernet and RS232 Access Server over G.SDSL Copper Pairs
The CopperWAY and CopperWAY-SW are compatible products with dual G.SDSL interfaces utilized in multipoint applications over a BUS or RING topology that distribute Ethernet and RS-232/485 ports.
