D3CM1604V EMTA Cable Modem Administrator Manual
Using the Reset Button
Using the reset button on the rear panel (see Figure 1-2 on page 13), you can perform two
types of reset operations with the EMTA:
ŸSoftware reset – this reset operation power-cycles the EMTA and retains its current
configuration settings.
ŸFactory default reset – this operation removes all overrides made to the EMTA’s factory
default configuration and returns the EMTA to its original factory default settings.
The number of seconds you press the reset button determines which reset operation is
performed. To protect against accidental resets, the reset button is recessed on the EMTA
rear panel.
Note: You can also reset the EMTA and retain its current configuration settings using the
RESET method described under “Configuring Security Settings” on page 40.
To use the reset button to perform a software or factory default reset:
1. Leave power plugged into the EMTA.
2. Find the reset button at the top of the back panel, then use a thin object to press and hold
the reset button as follows:
– To perform a software reset, press the reset button for at least 10 seconds.
– To perform a factory default reset, press the reset button for at least 15 seconds.
3. Release the reset button.

2 Installing the EMTA
This chapter describes how to install your D3CM1604V EMTA Cable Modem. The topics
covered in this chapter are:
ŸFinding a Suitable Location (page 17)
ŸConnecting to the LAN (page 18)
ŸConnecting the WAN (page 19)
ŸConnecting to the Public Telephone Network (page 19)
ŸPowering on the EMTA (page 20)

Installing the EMTA
17
D3CM1604V EMTA Cable Modem Administrator Manual
Finding a Suitable Location
Your D3CM1604V EMTA Cable Modem can be installed in any location with access to the
cable network. All of the cables connect to the rear panel of the EMTA for better organization
and utility. The LED indicators on the front panel are easily visible to provide you with
information about network activity and status.
For optimum performance, the location you choose should:
ŸBe close to a working AC power outlet when powering the EMTA using AC power.
ŸAllow at least one foot of space around the sides and top of the EMTA to provide
sufficient air flow around the device.
ŸNot expose the EMTA to a dusty or wet environment.
ŸBe an elevated location such as a high shelf, keeping the number of walls and ceilings
between the EMTA and your other devices to a minimum.
ŸBe away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, or the base for a cordless phone.
ŸBe away from any large metal surfaces, such as a solid metal door or aluminum studs.
Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors,
brick, and concrete can also affect your wireless signal.
ŸShould allow the EMTA to connect to an AC outlet that is not controlled by a wall switch.

Installing the EMTA

D3CM1604V EMTA Cable Modem Administrator Manual
Connecting to the LAN
Using an Ethernet LAN cable, you can connect the EMTA to a desktop computer, notebook,
hub, or switch. The EMTA supports auto-MDI/MDIX, so you can use either a standard
straight-through or crossover Ethernet cable.
1. Connect either end of an Ethernet cable to the LAN port on the rear panel of the EMTA
(see Figure 2-1).
Figure 2-1. Connecting to an Ethernet Port on the EMTA Rear Panel
2. Connect the other end of the cable to your computer’s network-interface card (NIC) or to
another network device (see Figure 2-2).
Figure 2-2. Connecting the EMTA to the a Laptop or Desktop Computer

Installing the EMTA
19
D3CM1604V EMTA Cable Modem Administrator Manual
Connecting the WAN
To connect the EMTA to a Wide Area Network (WAN) interface:
1. Connect a coaxial cable to the port labeled CABLE on the rear panel of the EMTA from a
cable port in your home or office (see Figure 1-2 on page 13). Use only manufactured
coaxial patch cables with F-type connectors at both ends for all connections.
2. Hand-tighten the connectors to secure the connection.
3. If the modem was not installed by your cable provider (ISP) or is replacing another cable
modem, contact your cable operator to register the D3CM1604V . If the modem is not
registered with your cable operator, it cannot connect to the cable network system.
Connecting to the Public Telephone Network
The rear panel of the EMTA has two RJ-11 telephone-style connectors labeled TEL1 and
TEL2. Each of these connectors can provide telephone service to multiple telephones, fax
machines, and analog modems.
The maximum number of telephone devices connected to each RJ-11 port is limited by the
total Ringing Load of the telephone devices that are connected. Many telephone devices are
marked with a Ringer Equivalent Number (REN). Each telephone port on the EMTA can
support up to a 5 REN load. The sum of the REN load on all of the telephone devices
attached to each port must not exceed 5 REN.
Before you use the EMTA’s RJ-11 connectors to power the analog devices in your home or
office, disconnect the telephone lines from any other provider at the demarcation point. If the
incoming phone line is connected to another provider, such as an incumbent telephone
company, it can result in potentially harmful voltage to the analog telephone line.
Note: The customer or the customer's wire contractor is responsible for adhering to all local
codes for wiring.
To set up the ability to place calls using a regular analog telephone line (PSTN), perform the
following procedure.
1. Disconnect the phone lines from any other provider at the demarcation point, if appropriate.
2. Connect the RJ-11 cable on an analog device to the TEL1 connector on the rear panel of
the EMTA.
3. Connect the RJ-11 cable on another analog device to the TEL2 connector on the rear
panel of the EMTA.

Installing the EMTA
20
D3CM1604V EMTA Cable Modem Administrator Manual
Powering on the EMTA
After making your connections, use the following procedure to power on the EMTA:
1. Connect the supplied power cord to the power port on the rear panel of the EMTA (see
Figure 1-2 on page 13).
2. Connect the other end of the power adapter to a working power outlet. The EMTA powers
on automatically, the POWER LED on the front panel goes ON, and the other front panel
LEDs show the EMTA’s status (see Table 1 on page 12).
WARNING:Only use the power supply supplied with the EMTA. Using a different power
supply can damage the EMTA and void the warranty.
