Motorola 2310-51 Business Single User VDSL Modem

This device is supplied to video digital subscriber line (VDSL)-eligible business customers who request high speed Internet (HSI) service and prefer the basic functionality of a modem vs. a gateway. When ordering VDSL-based service, business customers are provided with U-verse HSI service, but do not receive U-verse TV or U-verse Voice at that time.

Business customers must purchase their customer premises equipment (CPE), which includes a 30-day buyer's remorse (BRE) period and a one-year warranty for their CPE.

Note: The Motorola 2310-51 VDSL Modem is a standalone modem and cannot be accessed through tools such as CMS, MDC, and GUI.

Installation  

Jump to: Remove or Disable Conflicting Application | Check the Computer's Browser and System Requirements | Choose a Computer and Location | Filter Installation | First-time Power-up/Boot-up and Any Subsequent Factory Resets

Installation of this device is accomplished via full-technician installation. 

Remove or Disable Conflicting Applications

Internet-sharing software and PC-based firewall applications typically interfere with the modem and should be removed or disabled before installing the modem. The modem provides the same features as the products listed below. If any of the following or similar applications are installed on the computers, remove or disable them according to the manufacturer's instructions before proceeding. 

• Internet-sharing applications: Microsoft Internet Connection Sharing, Intel Anypoint ISS, and 3Com HomeClick
• Proxy software: Wingate and Sygate
• Security software: Norton Internet Security, Black Ice, and Zone Alarm

Check the Computer's Browser and System Requirements

Verify that the computers meet the following minimum requirements:

• Browser requirements:
  • Windows: Microsoft Internet Explorer 5.5 or higher, Netscape Navigator 4.7 or higher, or Firefox 1.0 or higher
  • Macintosh: Safari 1.0, Microsoft Internet Explorer 5.0, or Netscape 4.74 or higher
• System requirements:
  • Microsoft Windows 7, Windows Vista, Windows XP, Windows 2000, Windows NT 4.0 with Service Pack 6, Windows ME, Windows 98/98SE, or Mac OS 8.6 or higher

Choose a Computer and Location

Typically, the computer is located in the same room as the modem and the U-verse connection. Ethernet is the only connection method between the computer and the modem. Connect the computer to the modem. Save and close all open programs before beginning this process.

Note: Previous DSL customers may already have the filters referenced in the rest of this article already installed.

Filter Installation

Regular telephone and U-verse HSI signals are carried over the same line. Converting a regular telephone line to U-verse can cause high-pitched tones and static when using the phone. Installing a filter on every telephone or telephone device sharing the same telephone number as the U-verse HSI separates these signals and eliminates the noise. Do not install filters if the telephone line is only carrying a U-verse HSI signal.

Install the U-verse HSI Filter

1. Locate the phone jack where the modem will be located.
2. Insert the U-verse HSI filter into the jack.
3. If there is a phone, answering machine, fax machine, satellite TV equipment, or other phone device in this jack location, plug it into the filter port labeled Phone.
4. Install a filter on all other phone devices in the house (such as dial-up modems, fax machines, caller ID devices, and set-top boxes). Plug each of these devices into the filter port labeled Phone.

Wall-Mounted Phones

1. Lift the telephone from the wall pegs and disconnect the phone cord from the wall jack.
2. Connect the telephone cord from the back of the filter into the wall jack. Align the keyhole slots on the filter with the wall plate pegs and press down gently to secure.
3. Connect the telephone cord to the phone jack located on the front of the mounted filter.
4. Attach the telephone to the mounting pegs on the filter.

Ethernet Connection

1. Connect the dual-port phone filter to their wall jack.
   • Phone service is not required to set up high speed Internet.
2. If customer has a phone device that shares this jack, plug it into the port labeled Phone on the dual-port phone filter.
3. Connect the green data cable from the port labeled DSL on the dual-port filter to the phone line port on the modem.
4. Connect the yellow Ethernet cable from an Ethernet port on the modem to the Ethernet port on the PC.
5. Connect one end of the power adapter to the power port on the modem and plug the other end into an electrical outlet.
   • A blinking, then steady green power light indicates a successful power connection.
6. Check the connections:
   • With the computer completely started, verify the power and Ethernet indicator lights on the front of the modem are green. The Internet indicator light does not turn green until the modem software is installed and an Internet connection is established.

Note: A customer can have up to five communication devices at a time once in-house filters are installed.

First-time Power-up/Boot-up and Any Subsequent Factory Resets

Modem LED Sequencing and Timing

Inform the customer that during the first-time boot-up process, the modem automatically reboots. Customer interaction during this time is not necessary.

Boot Strap (First Contact with CMS) 

1. On boot-up, the Power LED is green for two seconds, blinks red for one second, and then goes solid green. All other LEDs are off.
2. After Power LED is solid green, DSL LED starts flashing red for approximately 4-6 seconds, flashes green for approximately 45 seconds, and goes solid green after ADSL line is up. While DSL is flashing red, Ethernet LED starts blinking green when a LAN device is connected to the Ethernet port. The Ethernet LED blinks green when traffic is received on the Ethernet port.
3. After the DSL LED is solid green, the Internet LED starts flashing green for approximately 4-5 seconds (802.1x authentication and IP connectivity takes place).
4. At the same time the Internet LED starts flashing green, the Activity LED starts blinking green. Activity LED continues to blink green when activity is seen from the broadband connection.

Reboot (CMS Issues the Reboot via 2310 Work Flow Modification 28-30 seconds after the bootstrap)

1. On boot-up, the Power LED is green for two seconds, blinks red for one second, and then goes solid green. All other LEDs are off.
2. DSL Power LED is solid green. DSL LED starts flashing red for approximately 4-6 seconds, flashes green for approximately 45 seconds, and then goes solid green after ADSL line is up. While DSL is flashing red, Ethernet LED starts blinking green when a LAN device is connected. The Ethernet LED blinks green when traffic is received on the Ethernet port.
3. After DSL LED is solid green, Internet LED starts flashing green for approximately 4-5 seconds (802.1x authentication and IP connectivity takes place).
4. At the same time the Internet LED starts flashing green, the Activity LED starts blinking green. Activity LED continues to blink green when activity is seen from the broadband connection.

Troubleshooting Tips

• The Motorola 2310 modem is not as robust as the 2701, 3600, and 3800 RGs, therefore troubleshooting is not robust. The 2310 supports HSIA only, with very limited programming and capabilities; troubleshooting is limited to the modem functionality.
• Troubleshooting is limited to determining if equipment is defective.
