Connecting to the Advanced Conﬁguration screens

There are three ways to connect to the Netopia Router’s advanced conﬁguration screens:

■

Through the console port, using a local terminal (see the

Started Guide

■

Using Telnet with the Router’s Ethernet port IP address (cannot be used for initial conﬁguration)

■

Over analog phone lines using a modem and terminal emulation software (see “Connecting a modem to the SmartPort,” below)

You can also retrieve the Netopia Router’s conﬁguration information and remotely set its parameters using the Simple Network Management Protocol (see “SNMP” on page 9-17).

Connecting a modem to the SmartPort

The Netopia Router has a SmartPort (also known as a PC Card port or a PCMCIA card port) for attaching a PC Card Type II modem. The port has two Type II slots and is located on the router’s left side behind a pull-down cover.

You may want to attach a Farallon approved PC Card modem to the Netopia Router to remotely conﬁgure it or to upgrade its ﬁrmware (see

“Updating ﬁrmware” on page 10-14 or page 10-18.) Contact Farallon

Customer Service for information on Farallon approved PC Card modems.

Introduction 1-5

Follow the manufacturer’s instructions when unpacking and preparing to use the PC Card modem. One end of the telephone cable connects to your modem, while the other end (RJ-11) connects to an analog telephone line wall socket (

you select Switched Async, skip to Step 6.

2. Select Data Rate (kbps) and press Return. From the pop-up menu, select a ﬁxed data rate for your digital line or select Auto. (The data rates to choose from range from 56 kbps to the highest synchronized line speed.) The Auto setting allows your Netopia Router to determine the data rate of your serial line at the time of circuit activation. Press Return.

Equipment) because their transmit data can become altered in relation to the clock sourced by the DCE (Data Communications Equipment).

A DTE (Data Terminal Equipment) is a term used to deﬁne the equipment rate. It is a designation for the maximum rate at which a router can exchange information.

A DCE (Data Communications Equipment) is a term deﬁned by both Frame Relay and X.25 committees, that applies to switching equipment and is distinguished from the devices that attach to the network (DTE).

DSR-only, or DCD and DSR. Press Return.

Some V .35 interfaces represent their capability to transfer user data end-to-end with the DCD signal, while others offer a more accurate representation with DSR. For this latter case, you may choose to use DSR-only.

2. Select Framing Mode and press Return. From the pop-up menu, highlight either ESF or D4, depending on the framing mode that your telephone service provider advises you to use. The default setting is ESF. Press Return.

3. The ANSI T1.403 standard deﬁnes Performance Report Messages (PRMs) that may be transmitted each second from a T1 Integrated CSU to the telephone service provider’s network. By default, the Netopia Router does not send PRMs. However, you can enable these transmissions by toggling Transmit ANSI PRMs to Yes.

4. Select Number of DS0 Channels and enter the number of DS0 channels that you and your telephone service provider have determined are necessary for your T1 line. The default setting for DS0 Channels is 1 (one). Press Return.

Note: Each DS0 channel represents a 56k or 64k increment in bandwidth. Selecting a number less than the maximum of 24 speciﬁes a fractional-T1 interface.

For fractional-T1, you may also specify in the check box whether the DS0 channels are contiguous or alternating.

5. Select First DS0 Channel and enter the number of the ﬁrst active DS0 channel you will be using. The default setting is 1 (one). Press Return.

Note: You may change the First DS0 Channel number, which has a valid range from one to the maximum number minus the number of active channels. If the number of active DS0 channels is 24 (maximum), First DS0 Channel is hidden.

6. Select Buildout (-dB) and press Return. From the pop-up menu, highlight the line Buildout, which is the transmit attenuation of your line that you will be using. The choices in the menu include Auto, 0-0.6, 7.5, 15.0, 22.5, and None. The default setting is Automatic. Press Return.

If Automatic is chosen, the attenuation of the transmission will be set to match the receiving signal level.

7. Select Channel Data Rate and highlight the data rate speciﬁed by your service provider. The channel data rate choices are Nx56k or Nx64k. The default is Nx64k. Press Return.

8. Select Clock Source and press Return. From the pop-up menu, highlight the clock source, that you wish to use. The choices offered are Internal Clock Source, or Network Clock Source. The default is Network. Press Return.

9. Select Data Link Encapsulation and highlight the method of encapsulation that you want to use from the pop-up menu. The choices offered are PPP, HDLC, and Frame Relay. The default setting is Frame Relay. Press Return.

10. You are now done conﬁguring the Line Conﬁguration screen. Press the escape key to return to the WAN Setup screen. Go to

page 2-13, for information on how to conﬁgure your leased line

connection proﬁle.

Line conﬁguration for a DDS line

The DDS Line Conﬁguration screen is where you enter the conﬁguration parameters for your leased line, in order for the Netopia Router to communicate with the physical connection. Use the information in the Leased Line worksheet in the Getting Started Guide as a reference when specifying your DDS line conﬁguration information.

DDS Line Configuration

Circuit Type... Permanent

Data Rate... Auto

Clock Source... Network

Data Link Encapsulation... Frame Relay

Enter Information supplied to you by your telephone company.

1. Select Circuit Type and press Return. From the pop-up menu, highlight Switched for a dial-up digital line or Permanent for a nailed-up leased line. The default setting is Permanent. Press Return.

Note: The DDS data rate is capable of handling 56 or 64 kbps. If the Switched circuit type is selected, 56 kbps data rate is the only available option. If the Permanent circuit type is selected, 56 kbps and 64 kbps data rates will be available.

2. Select Data Rate and press Return. From the pop-up menu, highlight the data rate that you want your DDS line connection to transmit at. The data rate choices are 56 kbps and 64 kbps. The default is Automatic. Press Return.

Note: As noted above, DDS Netopia Routers may run 56 kbps or 64 kbps data rates on permanent circuits. You may alternately select Automatic, in which case the router will hunt between modes until it can determine what the telephone company has provisioned your DDS line for.

Connection proﬁles for ISDN and Leased lines

A connection proﬁle is a set of parameters that tells the Netopia Router how to connect to a remote destination. Connection proﬁles are also used to make out-bound calls and optionally to help answer calls.

Some Netopia models support up to 4 different connection proﬁles while most models support up to 16 connection proﬁles.

To go to the Connection Proﬁles screen, select Connection Proﬁles in the WAN Setup screen.
