5.0 Home Menu
This menu can be reached at anytime during operation by pressing the home key, accessible on the rubber keypad.
BX100A Home Menu
BX100V Home Menu (CPE mode)
The upper part of the menu (DSL link, ATM, IP, Pass through, Bitstogram etc) contains items specific to the test application of the
handheld test set, while the lower part of the menu contains items common to all VeEX VePAL handheld test sets.
Some test capabilities may be specific to a certain product while other features may require the purchase of a software option in
order to be displayed or be enabled.
5.1 DSL Link
ADSL and VDSL technology re-uses the copper pair between the exchange or street cabinet and the customer premises. The
usable bandwidth is extended from 4kHz to 2.2MHz in the case of ADSL2+ and 4kHz to 30MHz in the case of VDSL2. Extended
bandwidths make the copper pair far more susceptible to faults, impairments and other degradation thus impacting the BER.
Testing at this layer not only provides information about the copper's performance, but connection to the DSLAM or customer's
modem can also be assessed.
The BX100A/V models offer the following test functions depending on model purchased;
Emulate customer modem (ATU-R) to prove that synchronization or link up with DSLAM is possible.
Emulate DSLAM (ATU-C) to prove that synchronization or link up with a customer modem (ATU-R) is possible (BX100V
with xTU-C options only)
Provide link performance statistics - Measure downstream bit rate, upstream bit rate, max bit rate, relative capacity, noise
margin, transmit power and attenuation.
Display bits per tone in both graphical and table format.
Display SNR per tone in both graphical and table format.
Counts FEC, HEC and CRC error frames and detects and indicates Loss of signal, Loss of cell declineation
Modem emulation - replace the customer modem and measure data performance with live customer traffic in Pass Through
mode.
5.2 ATM Function
The ATM link proves the communication path from the customer's equipment through the Service Provider's backbone network.
Testing the ATM layer verifies correct equipment setup.
