About the Hotwire POTS Splitter
The Hotwire®system enables simultaneous high-speed digital data access and
analog voice service over the same twisted-pair telephone line. The CO (central
office) POTS (plain old telephone service) splitter separates the DSL (Digital
Subscriber Line) and POTS frequencies.
Simultaneous access to POTS and data requires the installation of a POTS splitter
at the CO for:

ADSL/G.Lite (Adaptive DSL)

RADSL (Rate Adaptive DSL)

ReachDSL™

MVL®(Multiple Virtual Lines)

TDM SDSL (Time Division Multiplexer Symmetric DSL)
POTS Splitter Chassis
The Hotwire POTS splitter card is mounted in a Hotwire POTS Splitter Chassis.
Two chassis models are available:

Chassis Model 5011 – 1-slot chassis which can be placed on a tabletop or
installed in a rack.

Chassis Model 5016 – 6-slot chassis which must be installed in a commercial
EIA-standard 19″or 23″rack or cabinet.

Cables You Need
The POTS splitter card has three interfaces and each of the three POTS Splitter
card connectors requires a 50-conductor cable with a 50-pin Telco connector. Use
a minimum of 24 AWG.
Each DSL port at the DSLAM uses one pair of copper wires out of the 25 pairs on
each 50-position connector. The following tables show the cables that can be used
to connect 6050 and 7020 POTS splitter cards to the DSL interface at the DSLAM.

POTS Splitter Chassis Installation
Both the POTS splitter chassis and the Hotwire chassis are shipped with mounting
brackets that allow them to be mounted in a 19″or 23″cabinet or rack.
Planning the POTS Splitter Chassis Installation
To plan the bracket and chassis installation, determine:

Whether the DSLAM will be rack-mounted.

Width of the rack: 19″or 23″.

Chassis position in the rack: center-mounted or front-mounted.
Center-mounting is recommended for convenient access to cables.

Whether the rack has mounting rails with threaded or non-threaded screw
holes.
NOTE:

Installing the POTS Splitter Card
HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive components from damage
due to electrostatic discharge (ESD) during normal operation. When
performing installation procedures, however, take proper static control
precautions to prevent damage to equipment. If you are not sure of the
proper static control precautions, contact your nearest sales or service
representative.
Procedure
To install a POTS splitter card into the POTS splitter chassis:
1. Remove the slot filler panel, if necessary, by loosening the 1/4-turn fastener on
either side. Keep filler panels in all unused slots.
2. Slide the POTS splitter card into the chassis.
3. Tighten the 1/4-turn fastener on each side of the faceplate of the POTS splitter
card.

Cabling with an 8610 DSLAM or 8620 GranDSLAM
The DSL interface connectors are on the rear of the 8610 DSLAM and
8620 GranDSLAM chassis. This example shows the one-slot 24-port 6050 POTS
splitter card with two 12-port DSL cards connected via a Y-cable to the
8610 DSLAM.
See
Cables You Need
on page 4 for information about POTS splitter cabling.
Cabling to 4-Port DSL Cards

6050-A2-GZ40-20 August 2001 15
Cabling for 4-port RADSL, MVL, and TDM SDSL cards depends on whether you
use the front connector of an 8810 DSLAM or the rear connector of an
8810 DSLAM or 8820 GranDSLAM.

Front connectors of an 8810 DSLAM combine the tip and ring connections
from DSL port cards in 6 contiguous slots. With 4-port DSL cards, the front
connector services 6 slots for a total of 24 ports. The configuration example on
the left uses the front connector of an 8810 DSLAM with a Y-cable to two
12-port 7020 POTS splitter cards.

Rear connectors of a Hotwire 8820 GranDSLAM represent the tip and ring
connections of a single port card. With 4-port DSL cards, the rear connector
services 4 ports. The configuration example on the right uses the rear
connectors of an 8820 GranDSLAM and a connector block to combine three
4-port DSL cards to one 12-port 7020 POTS splitter card.

Securing Cables to the CO POTS Splitter
Cables can be dressed to the left or right depending on the wiring of the cable
heads. Make or procure cables suitable for your equipment layout.
Procedure
To secure a cable to the POTS splitter card:
1. Install the plastic tie-wrap anchor mount onto the POTS splitter card faceplate
on the cable exit side with the screws provided. Slide the tie wrap through the
anchor from the top.
2. Attach the cable head to the POTS splitter connector.
—If the connector on the cable has a long screw, tighten the screw directly
into the connector located in the circuit card. Discard the jack screws
provided.
—If the connector on the cable has a short screw, install the #4-40 jack
screw provided into the threaded hole of the connector in the circuit card.
Attach the short screw in the cable to the jack screw and tighten.
