Understanding Device Connections

• Rear Panel:
• Voice 1-4: Use to connect analog telephones to the device. Telephone service must be enabled by the service provider.
• Cable: Use to connect to the coaxial cable from your Internet service provider.
• Ethernet (Internet): Connects to an Ethernet-enabled device such as a wireless router using an RJ45 Ethernet cable.
• Power: Connects to the power adapter. Plug the other end into the wall power outlet.
• Battery: 8 hour internal battery.
• ATA: Used to connect additional voice hardware (not yet available in all markets).

Installing Modem

1. Connect the coaxial cable to the cable connector on the rear panel of the eMTA and connect the other end to the cable wall outlet. Do not bend or over tighten the cables, as this may strain the connector and cause damage. To connect an eMTA and a television to the same wall outlet, you must use a cable line splitter (not included).
2. Connect the Ethernet cable (supplied) to the Ethernet (Internet) port on the back panel of the eMTA and connect the other end to an Ethernet port on a wireless router (or other Ethernet-enabled device).
3. Connect an RJ-11 phone cable (not supplied) to Voice 1 through 4 starting with Voice 1 on the modem (when provisioned for voice service as specified by the service provider), and connect the other end to the phone port of the telephone. If voice service is not  provisioned through the service provider, telephone service is not available.
4. Connect the power adapter (supplied) to the Power port on the modem. Connect the other end to a power outlet.

Installation Diagram

Device Wall Mount Instructions
You can mount the modem on a wall using the included wall mounting kit. Two round or pan head screws are recommended. See the figure below for measurements.
To mount the device on a wall:

1. Secure the bracket provided in wall mounting kit to the wall using the 2 wall anchors and screws.
2. After the wall bracket is secure, place the device on the wall bracket. The device should snap into place.
3. There are 2 locking screws on the bottom of the bracket to secure the device to the bracket.

Note to CATV System Installer
This reminder is provided to call the CATV systems installer’s attention to section 820-93 of the National Electric Code, which provides guidelines for proper grounding and in particular, specify that the Coaxial cable shield shall be connected to grounding system of the building, as close to the point of cable entry as practical.

Reseting the Modem
Front Panel:

• Reset: Use the reset button to either reboot (power cycle) the modem or reset the device to factory default settings. When the reset button is pressed and held for 4 to 10 seconds, the device will reboot (power cycle). If the reset button is pressed and held for 10 seconds or more, the Spectrum eMTA will reset to factory default settings. Refer to the LED
• Behavior table on page 5 for the reset button LED behavior.
• Note: When the device is in a state that suggests a power cycle (the button icon and the surrounding ring are lit), a factory reset cannot be performed. The user must power cycle the device, then perform a factory reset.
