REBOOTING THE MODEM WITH THE R ESET BUTTON

The reset button on the back panel of your modem is provided to reboot the modem without the need to remove power .

Under normal circumstances, you will not have to use the reset button. On rare occasions, however, your modem may not respond. In this case, you need to perform a reset to get your modem running properly again (see

“Rebooting the Modem” on page 5-14 for information about rebooting the modem from the Web Interface, and “Rebooting the Modem” on page A-29 for information about rebooting the modem from the Command Line

Interface). To perform a reboot:

Step Action

1 Use the tip of an unfolded paper clip (or similar object without a sharp tip) to gently press the Reset bu tton

on the back panel of your modem for less than 5 seconds (see Figure 1-4). The modem then reboots.

IMPORTANT

Holding down on the Reset button for MORE than 5 seconds resets the modem to its factory default settings, essentially clearing all of your current configuration settings. For detailed information about resetting the modem’ s factory defaults:

• Using the Web Interface , see “Reset to Factory Defaults using the Web Interface ” on page 9-13.

• Using the reset but ton on the back panel of the modem, see “Reset to Factory Defaults using the Reset Button” on page 9-14.

CONFIGURING THE LAN

The LAN configuration sets up the interface between the mo dem 10/100Base-T LAN port and devices on the LAN. The LAN is managed by your network administrator, who will make the decisions concerning its topology.

For instructions on setting up the LAN interface for a point-to-point modem application, go to Chapter 7:

Implementing a Point-To-Point LAN Extension.

BEFORE YOU BEGIN

Your network administrator will:

• Determine if you will use the modem Ethernet port in auto, full- or half-duplex mode.

• Identify a subnet value, including IP addresses and subnet masks.

• Determine if DHCP for the modem is enabled. If it is enabled, determine if the modem will be configured as a: – DHCP client which receives an IP address from another device that is a DHCP server on the LAN – DHCP server (determine the range of IP addresses the modem will need to serve, and identify the DHCP

gateway and DNS server)

– DHCP relay agent (determine the IP address to which the DHCP functions will be relayed)

• Determine if DNS Relay mode for the modem is enabled. If it is, identify the IP address for the DNS server.

CONFIGURE THE LAN

From the LAN Configuration page, configure the parameters for the LAN as indicated by your system administrator. The default protocol for the LAN port is bridged.

Step Action

1 Select LAN on the menu bar, then select LAN Setup under LAN Options to access the LAN

Configuration page (see Figure 3-1).

Figure 3-1. LAN Configuration

MM70xG2-UM-03 3-1

Chapter 3: Provisioning April 14, 2006

Step Action

2 Configure the following parameters:

• LAN Protocol

The LAN protocol is set to Bridged and cannot be changed through the Web interface. If you want to change the protocol to Routing, use the command line interface (go to “Set Up the LAN” on page A-6).

• IP Address

See the LAN administrator for a LAN IP address. Do one of the following:

– Enter an IP address for the LAN (10/100Base-T) port provided by the LAN administrator – Use the default IP address for the LAN port, which is 10.0.0.1. If you choose to use the default IP

address, make sure the devices on your LAN are on the same subnet as this modem LAN port.

– If you want a DHCP server on your LAN to automatically provide the modem LAN port IP address,

select Client for the DHCP configuration (see DHCP Client below).

• Subnet Mask

See the LAN administrator for the subnet mask. Do one of the following:

– Enter the subnet mask for the LAN (10/100Base-T) port provided by the LAN administrator. – Use the default subnet mask for the LAN port, which is 255.255.255.0. If you choose to use the

default subnet mask, make sure it allows devices on your LAN to access the modem LAN port.

– If you want a DHCP server on your LAN to automatically provide the subnet mask in addition to the

IP address, select Client for the DHCP configuration (see DHCP Client below).

•DHCP Client

Note: If a DHCP server is not set up and active on your LAN, do not enable DHCP client.

DHCP Client mode is recommended for use only when bridging is used as the LAN protocol.

A DHCP server must be set up and active on the LAN prior to enabling this feature. When DHCP Client is Enabled, the modem automatically changes the LAN port IP address to all zero es so that the DHCP server on the LAN can immediately serve it an IP address. This parameter is used when the LAN port is in bridging mode only.

CONFIGURE DNS RELAY MODE

The DNS resolver on a DNS server maps human-readable addresses to IP address numbers. A human-readable address is one such as:

maggie.copro.company.com

As a DNS relay, the modem forwards requests for DNS resolution to another device on the LAN or WAN that performs the resolution service. When you enable DNS Relay mode, enter the IP address for the device that will perform DNS resolution. Either your service provider or LAN administrator will provide this IP address.

If the modem is configured as a DHCP client (see “Configure the LAN” on page 3-1), it is served a DNS address in addition to an IP address and subnet mask. The DNS relay will be automatically enabled and the DNS server IP address will be automatically displayed in the DNS server IP address field, as shown in Figure 3-3 on page 3-3.

If you do not enable DNS relay nor do you ena ble DHCP client, then you must add the IP address for a DNS resolver to the Internet Protocol (TCP/IP) se tup for your PC (or other DHCP client). See Step 2 on page 3-5 for more information on setting up this information.

b. Configure the following parameters when DHCP server is enabled for the modem: – DHCP Range Low

The lowest IP address value that the modem can serve when configured as a DHCP Server. A maximum of 20 IP addresses can be served by the modem. This IP address value is provided by your LAN administrator and must be on the same subnet as the modem LAN port.

– DHCP Range High

The highest IP address value that the modem can serve when configured as a DHCP Server. A maximum of 20 IP addresses can be served by the modem. This IP address value is provided by your LAN administrator and must be on the same subnet as the modem LAN port.

– Default Lease Time

The default amount of time, in seconds, that a device on the LAN can be bound to the IP address it was served before the lease expires. This value is provided by your LAN administrator.

– Max Lease Time

The maximum amount of time, in seconds, that a device on the LAN can be bound to the IP address it was served before the lease expires. This value is provided by your LAN administrator.

– DHCP Default Gateway

Enter the IP address of the DHCP default gateway that is provided by the LAN administrator for devices on the LAN. After you configure this IP address, the modem provides this IP address as a default DHCP gateway to requesting DHCP clients (such as PCs) on the LAN. If there are no gateways on the LAN, then the modem LAN port IP address can be assigned as the gateway.

– DHCP DNS Server

Enter the IP address of the Domain Name System (DNS) server that will translate human-readable addresses to IP addresses. The DNS server can be either on the LAN or the WAN side of the modem. The modem provides this IP address as a default DNS server to requesting DHCP clients (such as PCs) on the LAN. If the DNS server is on the LAN side of the modem, acquire the IP address from your LAN administrator . If the DNS server is on the WAN side of the server, acquire the IP address from the service provider.

If you enabled DNS relay on page 3-3 and entered a DNS server IP address, then enter the modem LAN port IP address as the DHCP DNS server.

• DHCP relay agent—The modem forwards the request for an IP address, DHCP default gateway, and DNS server IP address to a device acting as a DHCP server. The DHCP server can be either on the LAN or the WAN side of the modem. If on th e LAN side, acquire the IP ad dress fro m yo ur LAN admin istrator. If on the WAN side, acquire the IP addr ess fro m the service provider.

CONFIGURING THE WAN

The WAN configuration sets u p from 1 to 32 sessions between the modem and the service provider or between two G.shdsl modems (see Chapter 7: Implementing a Point-To-Point LAN Extension for more information). Each session can be configured separately, specifying the protocol, IP address, A TM connection identifier, ATM QoS, and more.

BEFORE YOU BEGIN

The following should be supplied by the service provider before configuring WAN sessions:

• Protocol for each session, where the choices are the following for a maximum of 32: – RFC 1483-Bridge (up to 8 sessions) – RFC 1483-Router (up to 16 sessions) – PPPoA or PPPoE (up to 8 sessions for either type)

• IP address and subnet mask for each session using RFC 1483-Router protocol.

• RIP version (each direction) for each session using RFC 1483-Router protocol or PPP: –RIP Version1 –RIP Version 2 – RIP Version 1 and RIP Version 2

• Encapsulation for 1483-Bridge or 1483-Ro uter, where the choices are: –LLC –VCMux

• Login and authentication for each session using PPP protocol, where the choices are: – login name and password – authentication type of either PAP, CHAP or None

• ATM parameters for each session, including: – VPI and VCI values – Quality of Service (QoS) which could be UBR or CBR and applicable cell rates

Note: The modem is shipped with factory defaults as a Remote modem.

With V3.2.0, there are two RFC-1483 WAN Brid ging sessions with PVC’s 0/35 an d 0/100. For point-to-point LAN extension applications, delete one WAN session.

CONFIGURING SYSTEM PARAMETERS

These configuration parameters affect system functions for the modem. Other system parameters used to manage or troubleshoot the modem (updating modem soft ware, for example) are in “Managing the Modem” on page 9-1.

Before You Begin

Determine the following before changing system parameters:

• If secured management access is required for the modem, add users and assign one of three predefined security levels: Default, Engineer, or Super User.

• If SNMP access to the modem is required, add SNMP co mmunitie s with either read or wr ite access.

• Add the IP address for the network default router through which p ackets are forwarded.

• If static routes will be used to predetermined destinations, identify the destination host or network IP address. Also, identify the next hop gateway IP address for devices on your LAN (for example, the modem LAN port IP address).

• If spanning tree protocol is required, based on one or both of the fo llowing conditions, then enable it: – RFC 1483-Bridge protocol is used for any session or for the 10/100Base-T port (LAN)

– there are multiple bridging devices on a LAN with more than one physical path connecting them and you want

to prevent loops

Otherwise, disable spanning tree protocol.

Assigning User Access

The modem provides secure access for managing and viewing modem configuration. Three levels of access are predefined and can be assigned to users you set up. These security logons are required for access to the Web interface or to access the command line interface through either the console port or through a telnet session. For the three levels of predefined access, it is recommended that you change the passwords for all three accesses to secure the modem for management. The following procedures show how to add, modify, or delete user accounts.

Step Action

1 Select System on the menu bar, then select User Administration under Configuration to access the

CONFIGURING DSL PARAMETERS

The DSL parameters set up the G.shdsl communication between the modem and a DSLAM or between two modems used in a point-to-point application. Typically, the DSL parameters for the modem are preset to immediately synchronize with the service provider (DSLAM application). However, you may be instructed to make changes to the DSL configuration. This chapter provides information for setting G.shdsl parameters when the modem is in an application as a DSLAM endpoint. For instruction on setting up G.shdsl parameters for a point-topoint modem application, go to Chapter 7: Implementing a Point-To-Point LAN Extension.

BEFORE YOU BEGIN

The following are configurable DSL parameters for the G.shdsl modem; change parameters only when instructed to do so by the service provider or your system administrator.

• The operating mode choices are Remote (use when the modem is an endpoint for a DSLAM application or the customer-side modem in a point-to-point application) or Central-Office (use only for the central office-side modem in a point-to-point application)

• Annex A or B provides the appropriate operating characteristics for G.shdsl, dependent on your geographical location.

• A margin value, in decibels, that must be met to initialize modem.

• Either fixed or adaptive mode that the modem will use to negotiate the best transmission rate at which both ends of the connection can synchronize.

• Wire pair mode: Single (two-wire), Dual (four-wire) or Dual-Enhanced can be selected only for the MM702G2 modem. The MM701G2 modem is used only in Single mode. Dual-Enhanced provides the Adaptive mode in four-wire operation.

• PSD mask is either symmetric or asymmetric. The values used to calculate the asymmetric mask are dependent on the Annex A or B you selected.

COMPLETE A G.SHDSL QUICK CONFIGURATION

Configure basic operating parameters for the modem.

MM70xG2-UM-03 6-1

Chapter 6: Configuring DSL Parameters April 14, 2006

Step Action

2 Configure the following parameters as directed by your service provider:

• Operating Mode

When the modem is connected to a service provider through a DSLAM, the operating mode is Remote (default setting).

When two modems are used in a point-to-point application (LAN extension, for example), one modem at the customer or user site is set to Remote and the second modem in the CO or wiring closet is set to Central-Office. For instruction on setting up G.shdsl parameters and other related parameters for a point-to-point modem application, go to Chapter 7: Implementing a Point-To-Point

LAN Extension.

• Standard Ann ex

Select one of the following Annexes:

– Annex-A for operating conditions typically found in the North American implementation of G.shdsl – Annex-B for operating conditions typically found in the European implementation of G.shdsl. This is

the default mode for the modem.

– Auto for automatically negotiating the Annex A or B standard by which this modem, and the device

to which this modem is attached, can operate.

• Startup Margin

The target signal-to-noise margin, in decibels, that the modem must achieve with a BER of 10 better to successfully complete synchronization. The default margin value is -10 dB. A lower margin may result in a higher data rate, but it can increase noise on the line. Possible values are -10dB through 10dB, or to completely Disable the margin.

• Bit Rate Mode

-7

Bit rate mode indicates how the modem synchr onizes with the device to which it is attached in either a Fixed or Adaptive mode. The default for the modem is Adaptive mode.

– Fixed mode indicates that the modem will synchronize with the other end (a DSLAM or another

modem) at a fixed bit rate through negotiation. The modem will synchronize at the best rate, up to the data rate specified (see “Data Rate (kbps)” on page6-4), that can be achieved by both ends.

– Adaptive mode indicates that prior to modem negotiating a rate, the modem performs an

adaptation phase during which it determines a best possible rate based on conditions of the line. After adaptive mode, the modem will then negotiate the best rate that can be achieved with the other end, based on the adaptation results.

better to successfully complete synchronization. The default margin value is -10 dB. A lower margin may result in a higher data rate, but it can increase noise on the line. Possible values are -10 dB through 10 dB, or to completely Disable the margin. The default value is -10 dB.

• Data Rate (kbps)

Data rate determines the max imum tr ansm ission rate , in kilobits per second, up to which th e modem can negotiate and synchronize with another device (modem or a DSLAM) to which it is attached. When the Bit Rate Mode (see “Bit Rate Mode” below) is set to Fixed, the range of values are (ADC modems comply with the standard G.shdsl data rate range):

– for the MM702G2 modem, 384 kbps to 4608 kbps, in 128 kbps increments – for the MM701G2 modem, 192 kbps to 2304 kbps, in 64 kbps increments

Rates down to 64 kbps are supported only when operating in single-pair, point-to-point mode with another ADC modem. (see Chapter 7: Implementing a Point-To-Point LAN Extension).

When the Bit Rate Mode (see “Bit Rate Mode” below) is set to Adaptive for an MM701G2 (Adaptive is default value) or for an MM702G2 set to Single Wire Pair Mode only (see “Bit Rate Mode” below), this field is automatically set to Adaptive. The default value is Adaptive.

• Wire Pair Mode

Indicates whether the G.shdsl modem is operating in a two-wire mode (Single), a four-wire mode (Dual), or a Dual Enhanced mode. For the MM701G2 modem, Single mode is the only setting available. For the MM702G2 modem, you can select Single, Dual mode, or Dual Enh anced mode. The default value is Single.

• Power Spectrum Distribution

The Power Spectral Density (PSD) plots the variations of signal power with signal frequency for the G.shdsl transmission between the modem and the DSLAM or the modem and another modem. Symmetric PSD indicates that the PSD mask for both sides of the transmission (the CO- and remoteside) are the same (symmetric).

Asymmetric PSD indicates that the PSD mask for both sides of the transmission (the CO- and remote-side) are not the same (asymmetric). There are two unique numeric values (AsymmetricRate1 and AsymmetricRate2) used to determine the asymmetric PSD mask based on the Annex A or Annex B standard that you selected (see page 6-3). AsymmetricRate1 is 784 kbps for Annex A and 2312 kbps for Annex B. AsymmetricRate2 is 1552 kbps for Annex A and 2056 kbps for Annex B.

Both ends of the connection must be set for the same Symmetric or Asymmetric PSD. The default is Symmetric.

• Bit Rate Mode

Bit rate mode indicates how the modem synchr onizes with the device to which it is attached in either

a Fixed or Adaptive mode. The default for the modem is Adaptive mode.

– Fixed mode indicates that the modem will synchronize with the other end (a DSLAM or another

modem) at a fixed bit rate through negotiation. The modem will synchronize at the best rate, up to the data rate specified (see “Data Rate (kbps)” above), that can be achieved by both ends.

– Adaptive mode indicates that prior to modem negotiating a rate, the modem performs an

IMPLEMENTING A POINT-TO-POINT LAN EXTENSION

Two ADC G.shdsl modems can be implemented in a point-to-point application (also called back-to-back). In this application, the modems can be used to connect remote LANs to create LAN extensions. In this point-to-point application, one ADC G.shdsl modem is set to Remote mode and the other ADC G.shdsl modem is set for CentralOffice mode. By bridging traffic betwe en these two modems, you essentially create one extended LAN that allows the use of a single IP subnet. Note you can also set up a routing session in back-to-back modem configu rations with MM701G2 and 384 to 4608 Kbps with MM702G2.

Although you can set up multiple sessions on these modems, only one RFC 1483-Bridge sessions is required for implementing a point-to-point LAN extension.

The ADC modems comply with the standard G.shdsl data rate range of 192 kbps to 2304 kbps. Additionally, rates down to 64 kbps are supported only when using the G.shds l modem in single-pair, point-to-point mode for a LAN extension application.

BEFORE YOU BEGIN

Determine which of these implementations apply for your application:

• Quick Install—If your application does not require custom configuration, you can use the default modem settings. To implement, the Remote mode modem is already configured with factory default configuration for implementing point-to-point LAN extension. The Central-Office modem requir es only two configuration changes to set the modem to Central-Office mode. These changes are described in “Complete a Quick Installation” below.

• Custom Configuration—If you implement custom configuration where you do not use factory default parameters for your modems, refer to “Complete a Custom Configuration” on page 7-3 to configure the Remote modem and to configure the Central-Office modem.

COMPLETE A QUICK INST ALLATION

Note: The modem is shipped with factory defaults as a Remote modem.

With V3.2.0, there are two RFC-1483 WAN Brid ging sessions with PVC’s 0/35 an d 0/100. For point-to-point LAN extension applications, delete one WAN session.

For example, set up a PC on the LAN-side of the Remote m odem and another PC on the LAN-side of the Central-Office modem. Then, transfer a file or ping betwee n the two PCs. This generates traffic and tests connectivity.

Step Action

1 On the front panel of one of the modems, check the status of the SYNC LED. If it is blinking, it is

attempting to establish communication with the other modem. If it is on solid green, it has already synchronized its connection with the other modem. See “LED Status Indications” on page 1-5 for further definitions of LEDs indications.

CONFIGURING NAT

SmartCNCT Security provides both firewall and security features for the modem, protecting it from unwanted intrusion. NAT, which is part of security, is the only SmartCNCT Security feature available this release.

Note: SmartCNCT Security, except NAT, is not supported in this release. Although the Web interface has

configuration for this features, do not change any settings other than those for NAT that are covered in this chapter.

BEFORE YOU BEGIN

• Set up WAN sessions. These sessions provide the external interface (public WAN IP address) to which NAT is bound.

• Identify all internal interfaces (private IP addresses) that you will bind to the external interfaces with which you bound NAT.

CONFIGURE NAT

NAT provides the ability to map private IP address on the LAN to public IP addresses (WAN) that are assigned to each session. This essentially hides the private IP addresses behind the public IP addresses assigned to WAN sessions. Prior to binding NAT to a WAN IP address, you should have previously set up PPPoA routed, PPPoE routed, or RFC 1483 routed WAN sessions (see “Configure a New WAN Session” on page 4-2). You cannot configure NA T for RFC 1483 bridged sessio ns.

Step Action

COMMAND LINE INTERFACE ACCESS

You can manage the modem using either the command line interface or the Web interface. Access to the command line interface is accomplished by either direct connection to the modem console port or through a telnet session (over a network).

This section provides instructions for accessing and using the command line interface. Access to the Web interface is accomplished through a Web browser using an internet connection. Chapter 2: Accessing the Web Interface for

Modem Management provides instructions on accessing and using the Web interface for management.

The Web interface is the more comprehensive of the two management interfaces and generally simpler to use. There are situations, however, in which using the command line interface is preferable to using the Web interface. For example, if you cannot connect to the modem through the DSL line and 10/100Base-T port, you can still manage the modem through the console port.

The following sections describe how to use the command line interface:
