Total Access 1240 Installation and Maintenance Practice

SHDSL Loop 1 LineProbing Menu

The SHDSL Loop 1 LineProbing menu (see
1240 line probe feature which performs a sequence of power measurements on the twisted
pair. From these measurements, the Total Access 1240 determines what the maximum line
rate is that it can connect at.
Another name for line probe is Power Measurement Modulation Session (PMMS). This session
is performed during the handshake or pre-activation phase of the G.SHDSL training
sequence. Once the line probe session is finished, the units will immediately attempt to train.
The SHDSL Loop 1 LineProbing menu options are shown in

Function
Line probing is disabled.
Current Condition specifies that the line probing
sequence should determine the maximum rate it can
run given the current conditions on the line at the time
of measurement.
Worst Case Condition specifies that the line probing
sequence should assume that worst case conditions
exist on the line and then determine the maximum rate
at which to run.
