5.7.2 4G.SHDSL-1-Port-4-Channel G.SHDSL WAN Interface Card

The 4G.SHDSL is the G.SHDSL service access module on the AR routers.

G.Single-Pair High-Speed Digital Subscriber Line (G.SHDSL) uses trellis coded pulse
amplitude modulation (TCPAM), provides up to 5.696 Mbit/s symmetric data rates, and supports
2/3/4-pair binding. The transmission rate can automatically adapt according to the line length
and conditions. G.SHDSL provides a longer transmission distance than ADSL.
