About the Hotwire
MVL
POTS Splitter
The Hotwire MVL (Multiple Virtual Lines) System enables simultaneous
high-speed digital data access and analog voice service over the same
twisted-pair telephone line. The simultaneous access to MVL and POTS (Plain
Old Telephone Service) requires the installation of a POTS splitter at the central
office (CO). A CO POTS splitter is not necessary when the MVL line is not used
with analog voice for POTS.
The POTS splitter filters out the MVL signal and allows the POTS frequencies to
pass through. Each central office POTS splitter card contains 12 filters to serve
12 local loops with MVL-based service and POTS. The POTS splitter card is a
passive device and requires no power. The POTS splitter chassis is shipped
separately from the POTS splitter card(s). Two chassis are available:
1-slot chassis which can be placed on a tabletop or installed in a rack.
6-slot chassis which must be installed in a commercial EIA-standard
19
″
or 23
″
rack or cabinet.
Before You Begin
Consider the following before installing the POTS splitter:
Installation Site
The location should be well-ventilated, clean, and free of environmental
extremes. Allow clearance at the front of the POTS splitter chassis to provide
access to the cables.
Cabling
Three Telco 50-conductor cables are used to connect to the three interfaces
on the POTS splitter card. The location of the system hardware affects the
length of the three cables.
Cables and Hardware You Need
For each POTS splitter card, obtain three Telco 50-conductor cables with
50-position amphenol-type connectors at the appropriate length based on cabling
requirements in your environment.
