Alcatel-Lucent Enterprise
DSL Port (VDSL2/ADSL)
Fig. 12:
The splitter
By default, the supported modes do not allow the use of basic service devices (PSTN or ISDN depending on the
model) directly connected to the same line. You need to use a device known as a splitter, which separates the basic
service band frequencies from those used by the DSL connection. This ensures there is no interference between the
telephone and the DSL service.
A typical installation with a splitter is shown in figure 14.

The micro-filters
Only certain DSL operating modes (eg, G.Lite or ITU G.922.2) allow, with the help of a micro-filter, the use of some
basic service devices (PSTN or ISDN) directly connected to the same line. This device ensures the DSL signal does
not reach the basic service device, and that undesired signals generated by the device do not interfere with the DSL
signal.
A typical installation with micro-filters is shown in figure 15.
