FCC Part 68 Statement

This equipment complies with part 68 of the FCC rules. On the rear panel of this equipment is a label that contains, among other information, the FCC

registration number and ringer equivalence number (REN) for the equipment. If requested, this information must be provided to the telephone company.

The REN is used to determine the quantity of devices that may be connected to the telephone line. Excessive RENs on the telephone line may result in the

devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0). To be certain of the number

of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum REN for the

calling area.

This equipment uses the following USOC jack: RJC. An FCC-compliant telephone cord and modular plug is provided with this equipment. This equipment is

designed to be connected to the telephone network or premises wiring using a compatible modular jack that is Part 68 compliant. This equipment cannot be

used on telephone company-provided coin services. Connection to Party Line Service is subject to state tariffs.

If this equipment causes harm to the telephone network, the telephone company will notify you in advance that the temporary discontinuance of services

may be required. If advance notice isn’t practical, the telephone company will notify the customer as soon as possible. Also, you will be advised of your right

to file a complaint with the FCC if you believe it is necessary.

The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment. If this

happens, the telephone company will provide advance notice in order to maintain uninterrupted service.

If the trouble is causing harm to the telephone system, the telephone company may request that you remove the equipment from the network until the

problem is resolved.

Industry Canada CS-03 Statement

The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network
protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The
department does not guarantee that the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with
the above conditions might not prevent degradation of service in some situations. Only a representative designated by the supplier should
coordinate repairs to certified equipment. Repairs or alterations made by the user to this equipment, or equipment malfunctions may give the
telecommunication company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water
pipe system, if present, are connected together. This precaution may be particularly important in rural areas. Users should not attempt to make

DCT5100 Installation Manual

Section 2

Overview

The DCT5100 is adaptable to various software platforms. It supports existing entertainment,
analog, on-demand, and digital broadcast interactive services. The DCT5100 provides high
definition video output.

The DCT5100 includes two 6 MHz tuners with analog AMS-VSB, digital MPEG-2, and digital
DOCSIS data-receive capability for services such as Web enhanced TV. It also supports a
variety of consumer electronic interfaces including S-Video, SPDIF (AC-3 Electrical and
Optical), Ethernet, USB, HPNA for home networking applications, and IEEE 1394
(Firewire-optional) for interfacing to other consumer electronic devices.

Triple Tuner™

The DCT5100 has a unique Triple Tuner™ architecture. One tuner is dedicated to video
services, another to the DOCSIS channel for high-speed data services, and the third tuner is
used for the out-of-band control channel. Users have the capability of simultaneously
performing high-speed Internet access and IP Telephony functionality while continuing to watch
traditional video services. The DOCSIS tuner can also be shared by an external device through
an Ethernet connection on the back panel without interrupting TV viewing.

Front Panel

The controls on the front panel provide functional navigation of the DCT5100 if the remote
control is lost or is temporarily out of service. Certain functions, such as those requiring a
numeric entry, are not available without a remote control. Figure 2-1 illustrates the front panel,
which contains selection and tuning buttons, various displays, the power switch, and connectors
for USB, audio and video:

RF Bypass Switch Cabling Diagrams

The RF Bypass switch enables the cable signal to pass directly to a cable-ready TV, bypassing
the DCT5100. The bypass mode is automatically initiated under one of three conditions: when
the DCT5100 loses power, when it is turned off from the front panel, or when the user manually
activates the switch by pressing the A/B key. If the DCT5100 loses power or is turned off, the
subscriber can continue viewing the clear analog channels on the cable system. Activating
bypass mode enables you to tape a tuned channel from the DCT5100 while watching a different
clear channel that is bypassed to the TV.

Proper operation of the RF Bypass feature requires special configuration information from the
control system, and proper user interface settings in the Electronic Program Guide (EPG).

Figure 3-2 illustrates RF cabling to an optional VCR using the RF Bypass switch. When a VCR
is not present, install the supplied jumper cable from the
switch.

Audio/Video Cabling Diagrams

The DCT5100 is capable of delivering Dolby AC-3 audio to a Dolby Digital stereo receiver using
the SPDIF RCA connector. When connecting to a receiver, you can use the left/right RCA
baseband audio outputs or the SPDIF RCA connection. The connections you use will depend on
the capabilities of the audio receiver. The SPDIF port carries the audio stream in either a PCM
or Dolby AC-3 format. If the subscriber does not have a Dolby Digital receiver, use the baseband
Left/Right audio RCA connections to interface to the audio receiver.

The following illustrations show audio/video connections to a digital receiver, where the receiver
functions as an audio/video router. When connecting the audio path to a digital receiver,
reference your receiver’s installation instructions for directions on connecting to baseband and
SPDIF ports.

DCT5100 Installation Manual

Installation 3-5

The VCR and TV receive their audio/video signals from the currently selected input device on the
digital receiver. This is important when the subscriber has another audio/video device such as a
DVD player, a secondary VCR, a CD player, or other electronic component. It is recommended
that you connect the TV to the monitor output so On-Screen menus associated with the receiver
can be displayed. (In many cases the receivers themselves have interactive on-screen menus).

mounting bracket is a clear plastic holder that has a pad of adhesive tape that enables you to
install the IR Blaster near the VCR IR receiver. A mini-pin connector at the end of the cord
connects the IR Blaster to the DCT5100. The IR Blaster is sold separately as an accessory item.

The availability and functionality of the IR Blaster depends on the installed application
software.

Figure 3-8 illustrates the IR transmitter installed in the mounting bracket:

Figure 3-8
IR transmitter installed in mounting bracket

Once installed, the IR Blaster is activated automatically through the electronic program guide.
Individual VCR codes are broadcast through the out-of-band data channel and are updated
periodically as new codes are added.

The procedure for installing the IR Blaster is described in the following paragraphs.

Locating the IR Receiver on the VCR

The IR receiver area is not visible on some VCRs. To locate it:

 Obtain a piece of opaque material, such as a 3- by 5-inch index card.
 Use the card to block off areas of the VCR where the IR receiver might be located. Try to

turn the VCR on and off with the remote control pointed directly at it, and close enough to
reduce the possibility that the receiver will see IR reflections.

 Note the blocked area where the VCR is unresponsive to the remote control. This region

contains the sensor and can be marked by loosely taping the index card to the area.

Because the IR Blaster radiates in an area approximately 40 degrees wide, you do not need to be
precisely on target with the receiver. You may prefer to offset the location of the IR Blaster
transmitter so that it is less likely to interfere with operation of the VCR remote control.

Boot Cycle

After connecting the proper cabling to the DCT5100, plug the power cord into the DCT5100 and
electrical wall outlet. Begin performing the boot cycle procedure:

 The LED displays HUNT and then FR 1.
 The DCT5100 begins searching for the headend Out of Band (OOB) frequency carrier. If the

OOB frequency is not set to 75.25 MHz, the LED flashes FR 1 and then flashes FR 2. This
searching process repeats until the correct OOB frequency is found and the required
message for your set-top model is acquired. Table 3-1 illustrates the LED displays and OOB
frequencies:

 When multiple OOB frequencies are used, the DCT5100 pauses 40 seconds on each valid

frequency. The LED displays dl and a progress indicator, which identifies a software object
download. The progress indicator, or crawling ant, moves one position around the dl display
for each segment of download received. If the dl stops moving up and down on the LED for
an extended period of time, contact the headend operator.

The progress indicator usually moves at a consistent rate as segment downloads are

received. If all the segments are retrieved in the first pass, the EF, AU and FP messages are
displayed on the LED. If segments are dropped, the progress indicator appears to stall and
then inch forward after the dropped segments are retired.

When the progress indicator alternates between rapid and sluggish movement, this may

indicate that the stream is spinning too fast for existing plant conditions.

 The LED displays EF for up to 60 seconds when the software object download is complete

during flash erasure and then displays FP for up to 60 seconds during flash programming.

 The DCT5100 is ready for initialization by the headend controller when the LED display is

blank. Verify that the DCT5100 is powered up or reset within two minutes of a completed
download.

MAC ABORT COUNTER

The MAC ABORT COUNTER increments every time the MAC layer reaches the Cell Abort
Count limit. The MAC ABORT COUNTER is reset by the successful upstream transmission of a
cell, for example, when an ACK is received by the set-top.

If the MAC ABORT COUNTER reaches the MAC Abort Count limit, the set-top assumes the
MAC layer is unavailable due to noise, congestion, or some other problem. The set-top will stop
transmitting data upstream, report an error to the calling function, and attempt to re-enter the
network using the initialization process.

0000 is displayed as default or if the MAC ABORT COUNTER is not configured or unknown.

DCT5100.

Aim the remote control directly at the DCT5100, not the TV or VCR.

Press and release operation keys one at a time, firmly and
deliberately.

Try changing channels using the buttons on the front panel.

Check the batteries in the remote control and install new batteries if
needed.

Press

MUTE

on the remote control to restore sound.

Check that you have the correct cables for the audio ports.

Verify that the TV set is tuned to the output channel 3 or 4 of the
DCT5100.

Check that you have selected the correct video output mode. The
default mode is standard video available on RF, S-Video and
Baseband.

If you are using component video outputs, you must set the video
output to the correct format (1080i, 720p, 480p or Native). When
component outputs are selected, the other outputs will not pass
