The standard CFA designation for
the Line Sharing splitters will be by Port. Each Port
will consist of two pair terminations, one for the LINE
side of the splitter that is to be jumpered to the subscriber's
serving pair, the other for the POTS RETURN side of
the splitter that is to be jumpered to the Central Office
switch line circuit.
The CFAs are to be designated according to the port
as terminated on the MDF block. Since the usable ports
on this universal MDF termination will vary, depending
on the splitter shelf used by the CLEC, management and
administration of the CFA is a CLEC responsibility.
The CLEC is responsible to only designate CFA terminations
that are usable, based upon their splitter shelf wiring.

Collocator's splitter ports are to
sequentially numbered by individual collocator. The
splitter port numbers on the first terminal block will
begin at 1 and end at 50. The port numbers will continue
with 51, on the second block, and end at 100. Each additional
block will continue the sequential port numbering to
the last port terminated on the last terminal block
for any individual collocator's arrangement.
A different Collocator will again begin numbering at
port #1 and continue to the last port terminated.

Since 50 line sharing ports can be
contained in a single block, MDF space will be required
to mount the number of blocks required to meet the Collocator's
requirements
Category 5 cables are required for the Line side of
the splitter from the MDF block to the Collocator's
splitter, since this cable carries high frequency signals.
Normal switchboard (Category 3), or Category 5, cable
may be used for the POTS RETURN circuits that only carry
voice frequencies. For Virtually collocated splitters,
Category 5 cable is also required for the xDSL cable
from the splitters to the DSLAM equipment, because it
also carries the high frequency signals.
