DSL Port Settings
DSL port settings provide the interface to configure the port transmission speed
IEX-402-SHDSL Series
Description
Setting Description Factory Default
Standard Display the standard of DSL port G.SHDSL.bis
Name
Setting Description Factory Default
Max. 63 characters Specifies an alias for the port to help administrators
differentiate between different devices. Example: Site_A
None
Mode (SET/ACT)
Setting Description Factory Default
Device type SET: The value same as CO/CPE DIP switch configuration
ACT: The value after connected pairs negotiation
CO/CO or CPE after
negotiation
Turbo
The IEX-402-SHDSL series support two communication modes; Standard (STD) and Turbo. The difference is
the transmission data rate, highest up to 5.7Mbps and 15.3Mbps for standard and turbo mode respectively. The
higher the transmission data rate, the shorter the connection distance. In other words, lower data rates can
extend the transmission over a longer distance.
In standard mode, the connection speed is decided once the connection is established between the CO and the
CPE based on line conditions, including distance, SNR (signal-to-noise ratio) and cable quality. However, the
transmission speed of Turbo mode will be auto detected from 5696 Kbps to 15.3 Mbps gradually. It should take
less than 7 minutes to complete the training process.
Setting Description Factory Default
Turbo mode status Indicates whether turbo mode is enabled or not based on DIP
switch configuration
Disabled
Speed
Transmission speed can only be configured while Turbo mode is disabled. It shows the list of configurable
transmission speeds.
Setting Description Factory Default
Transmission speed Auto: Allows the DSL ports to
negotiate the best transmission
speed based on line conditions.
Fixed speed: Manually assigning one of these fixed speed
options:
192K, 384K, 512K, 768K, 1024K, 1280K, 2048K, 2304K,
2688K, 3072K, 3456K, 4224K, 4608K, 4992K, 5376K, 5696K
Auto
NOTE
Device will try to attain the set speed. If line
condition degrades
(reducing SNR) but the device is able to keep
the link, the DSL SNR/SPEED LED is the indicator to notify user of the reduced SNR. However, if the line
condition is too poor to maintain the link, the connection will be very unstable or di
sabled to re-establish
connection, MOXA recommends manually assigning a lower transmission speed or to auto mode until the link
is able to be established.
