G.SHDSL Tests
The G.SHDSL option is only available if your organisation
has purchased this option. For details contact your Agilent
Technologies representative.
G.SHDSL is a high speed, symmetric Digital Subscriber
Line (DSL) technology carrying payload data of between
192kbps and 2.312Mbps over a single copper pair.
G.SHDSL groups parts of traditional DSL technologies into
a single, internationally recognized industry standard,
G.991.2.
G.SHDSL is purely digital. In ADSL, POTS is transmitted
as normal analogue to allow POTS to be used over existing
phone lines. Some performance can be lost due to the higher
frequency attenuation that occurs, as well as increased
sensitivity to bridged taps. G.SHDSL uses the lower band of
frequencies digitally to achieve range performance as well
as maintaining the ability to transmit voice or data services
symmetrically.
