4.2.8 "DMM" settings menu
Effective DSL service testing requires that every layer of the DSL stack can be tested
individually; at the Physical, DSL, ATM, IP, PPP and Application layer. Before higher layer
testing is performed, it is important to check the quality of the local loop. The quality of the
local loop can be easily determined with the standard tip-to-ring (T-R), tip-to-ground
(T-G), and ring-to-ground (R-G) parameters used to perform the following basic
measurements: DC Voltage, DC Current, Loop Current, AC Voltage, Loop Resistance,
Isolation Resistance and Capacitance.
The use of a digital multimeter provides the telecomms technician with an invaluable
source of information regarding the condition of the local loop. The DMM can be used for
both basic installation/commissioning and basic troubleshooting activities.
In the main settings menu, move the cursor to the position of "Function" and press "F4"
key to reveal the DMM option. And press "F3" key to select
shown in Fig 17.
