Note:
In the circumstance where the first connection example is not applicable and
you choose to use the second example, you must install a MicroFilter on the
telephone cable (as illustrated in Figure 3.3-2, do not use a splitter to replace
the MicroFilter).
Installing a telephone directly before the splitter will lead to a failure of
connection between the ZXDSL 831/831B/831II/831BII and the device at
central office side, or a failure of access into the Internet, or a slow connection
speed. If you really need to add a telephone set before the splitter, you have to
add a MicroFilter before the telephone set. Do not connect several telephones
before the splitter. Moreover, do not connect several telephones with
MicroFilters.
The filter is not a standard-configuration device and you should separately
purchase it from the operator.
