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. Simultaneous
access to RADSL (Rate Adaptive Digital Subscriber Line), M/SDSL (Multirate
Symmetric DSL), or MVL(Multiple Virtual Lines) service and POTS (Plain Old
Telephone Service) requires the installation of a POTS splitter at the central
office (CO). The CO POTS splitter separates the DSL and POTS frequencies.
Four CO POTS splitter models are available:
5020 RADSL 12-port Card
6020 MVL 12-port Card
6024 MVL 24-port Card
7020 M/SDSL 12-port Card

CO POTS
Splitter Card
The POTS splitter card is mounted in a POTS splitter chassis. Two chassis are
available:
Model 5011 – 1-slot card chassis which can be placed on a tabletop or
installed in a rack.
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:
Use interface connector labeled . . . To connect to the . . .
DSL RADSL, MVL, or M/SDSL interface on the
8600, 8610, 8800, or 8810 DSLAM, or 8820
GranDSLAM.
LOOP Local loop via the MDF.
PSTN PSTN switch.
Each of the three connectors of the POTS splitter requires a 50-conductor cable
with a 50-pin Telco connector. Use a minimum of 24 AWG.
Each DSL or MVL port uses one pair of copper wires of the 25 pairs on each
50-position connector. The following table shows the cables required in addition
to those used to connect the POTS splitter to the local loop and the PSTN
switch.

Planning the POTS Splitter Chassis Installation
To plan the bracket and chassis installation, determine:
Whether the DSLAM will be rack-mounted. If your Hotwire 8600 Series
DSLAM chassis is being placed on a tabletop, install the rubber feet as
shown on page 5. Discard the rubber feet for any rack-mounted chassis.
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:
Install chassis in the rack from the bottom up to maintain stability.

Cabling for an 8800 Series DSLAM and 4-Port Cards
Cabling for 4-port RADSL, MVL, and M/SDSL cards depends on whether you
use a front connector of an 8800 or 8810 DSLAM, or a rear connector of an 8810
DSLAM or 8820 GranDSLAM:
Front connectors of an 8800 or 8810 DSLAM combine the tip and ring
connections from port cards in 6 slots. If the cards are 4-port cards, the front
connector services 24 ports.
Rear connectors of an 8810 DSLAM or 8820 GranDSLAM represent the tip
and ring connections of a single port card. If it is a 4-port card, the rear
connector services 4 ports.
The following examples show cabling for 4-port RADSL, MVL, or M/SDSL cards
and 12-port POTS splitters.
The configuration on the left uses a front connector of an 8800 or 8810
DSLAM.
The configuration on the right uses rear connectors of an 8820 GranDSLAM.

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:
1. Install the plastic tie-wrap anchor mount onto the 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.

M/SDSL Port Cards: Determining the Software
Revision Level
The revision level of the software in an M/SDSL port card must be P6.02.00 or
above for the unit to work properly with the POTS splitter. (The P in the firmware
revision level is a mnemonic for POTS. Firmware releases not beginning with P
are not compatible with POTS.) To determine the revision level, follow this menu
selection sequence to display the Identity screen:
Main Menu → Status → Identity
M/SDSL Port Cards: Downloading Software
If you determine you require updated software, download software from the
Paradyne World Wide Web site, then download it to your termination unit.
Procedure
To acquire the software:
1. Request access to the Paradyne World Wide Web Subscriber Download
Page from your customer support representative.
2. On the Download Page, locate and click on the download file for version
P6.02.00 or above.
3. The file is compressed. Save the file on your PC and execute it to expand it,
creating a file with the suffix .ocd. Move the file, if necessary, to a directory
accessible to your TFTP server.
Procedure
To download software from your TFTP server using the Download Code screen:
1. Follow this menu selection sequence:
Main Menu → Control → Download Code
2. Position the cursor in the Image File Name field. Type the name of the .ocd
file to be downloaded.
3. Position the cursor in the TFTP Server IP Address field. Type the IP address
of your TFTP server.
4. Position the cursor in the Immediately Apply Download field. Select Yes.
5. Position the cursor at the Start Transfer field. Use the spacebar to select Yes.
Press Enter.
6. When the data transfer is complete, the Transfer Status field changes to
Completed successfully.
