About the Hotwire 5020 RADSL POTS Splitter
The Hotwire RADSL System enables simultaneous high-speed digital data
access and analog voice service over the same twisted-pair telephone line. The
simultaneous access to RADSL (Rate Adaptive Digital Subscriber Line) and
POTS (Plain Old Telephone Service) requires the installation of a POTS splitter
at both ends of the local loop; i.e., at the central office (CO) and at the customer
premises (CP).
The POTS splitter filters out the DSL signal and allows the POTS frequencies to
pass through. Each central office POTS splitter card contains 12 filters to serve
12 local loops with DSL-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:
Single-card chassis which can be placed on a tabletop or installed in a rack.
Six-card 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. A Y-cable is available for the DSL connection.

Planning the POTS Splitter Chassis Installation
The POTS splitter chassis is shipped with mounting brackets to allow installation
in a rack that is either 19″ or 23″ wide. To plan the bracket and chassis
installation, determine:
Width of the rack: 19″ or 23″.
Chassis position in the rack: center mounted or front mounted. Center
mounted is recommended for convenient access to cables.
Whether the rack has mounting rails with threaded or non-threaded screw
holes.
If a single-card 8600 DSLAM chassis is being placed on a table top. If so,
plan to install the rubber feet as shown on page 2. Discard rubber feet for
any rack-mounted chassis.
NOTE:
In order to reduce the risk of accidental tip over, it is strongly recommended
that the chassis be installed into the rack from the bottom up.

Installation into a Rack without Threaded Screw Holes
Procedure
After installing the appropriate brackets on the chassis:
1. Determine the preferred placement of the chassis in the rack.
2. Insert a speed nut onto each mounting rail hole selected and align the hole of
the speed nut with the hole in the rail.

3. Use a Phillips screwdriver to install the:
— Single-card chassis in 19″ or 23″ rack, or a six-card chassis in a
19″ rack.
— Six-card chassis in a 23″ rack. Install the top two screws loosely enough
to allow the bracket’s upper keyholes to drop under the screw heads
during installation.
4. Line up the chassis-mounting bracket with the speed nut and start to rotate
the speed nut screw into the chassis mounting bracket and the speed nut.
5. Loosely install the bottom screws first and then the top screws. Tighten each
screw until the head is flush with the chassis and securely mounted in the
rack.
To install the next chassis in the same manner, follow Steps 1 through 5. For a
standard rack installation, chassis can be mounted directly on top of each other.
Installing the Ground Wire
To comply with National Equipment Building Standards (NEBS) requirements, the
ground wire must be installed.

Cabling Overview
The interfaces to both the POTS splitter card and the DSLAM use 50-position
amphenol-type connectors. Each DSL line uses one pair of copper wires. Each
POTS splitter card uses 12 pairs of the 25 pairs on each 50-position connector.
The 12 pairs for the POTS splitter card can be connected directly to the DSLAM
using a straight-through cable or connected directly to the MDF. In order to
directly connect 24 POTS splitter pairs, use a Y-cable to combine 12 pairs from
two POTS splitter cards.
The Y-cable part number is 8000-F1-001.
12
5020-A2-GN10-20
March 1998
Cabling Examples
To connect 24 pairs from two POTS splitter cards to the DSLAM, use a Y-cable.
The DSLAM connector feeds 24 DSL ports, comprised of six slots with four ports
per DSL card slot.
Interface connections:
DSL Interface connects to the 8800 DSLAM using a Y-cable. The Y-cable
enables 24 POTS splitters to serve 24 DSL lines on the DSLAM.
LOOP Interface connects to the local loop via the main distribution frame.
PSTN Interface connects to the local PSTN switch.
In the next example, the first two POTS splitter cards are combined using the
Y-cable, part number 8000-F1-001.
