Overview

®

The Patton Model 3224 (see figure 1) and ForeFront
software platforms. The 3224 is a central site standalone device which connects and routes up to 24 G.SHDSL
subscribers directly. The Model 6081RC is installed in Patton’s ForeFront chassis system at a central site and
routes/bridges DSL subscribers data when used in conjunction with Patton’s model 3096RC( 16-port
G.SHDSL TDAC) and/or 3196RC (16-port iDSL T-DACS).

The Models 3224 IpDSLAM and 6081RC EdgeRoute Network Access Server powerful routing engines enable
network engineers to deploy flexible bridged or routed applications. Routed links can be configured using
Static, RIP (Routing Information Protocol), or OSPF (Open Shortest Path First) protocols. This guide
addresses configuration steps needed for bridged data and routed applications.

Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

Introduction

The Models 3224 and 6081RC share routing and bridging software platforms, and both are central
site devices.

The 3224 is equipped with 24 G.SHDSL ports running at speeds from 192kbps to 4.6Mbps. The G.SHDSL
ports connect to customer premise G.SHDSL modem/routers such as the Patton Model 3201.

The Model 6081RC is mounted on a Patton Electronics ForeFront chassis (Models 6276, 6476, or 6676). The
6081RC connects to ForeFront function cards such as the 3096RC, 3196RC, 2616RC, or 6511RC via a mid­plane H.110 bus. In G.SHDSL applications, DSL frames carrying data from customer sites are terminated at
the ForeFront chassis by a Model 3096RC; data is then passed to the model 6081RC via H.110 ports.

Physical layer characteristics

The Model 3224 has 24 G.SHDSL ports structured in nx64kbps timeslots from 192kbps to 4.6Mbps, and
two 10/100base-T Ethernet ports.

The Model 6081RC has 32 H.110 ports (each port structured in 128 unidirectional 64kbps slots), and three
10/100base-T Ethernet ports.

This chapter contains the following sections that describe configuring the Model 3224 G.SHDSL ports and
Model 6081RC H.110 ports:

• “Configuring Model 3224 G.SHDSL parameters” on page 11

Configuring Model 6081RC H.110 parameters

The Model 6081RC card routes/bridges data from H.110 and Ethernet ports. The 6081RC connect to the
ForeFront chassis H.110 bus via mating mid-plane connectors.

There are 32 H.110 ports available on the ForeFront chassis H.110 bus, Each of the function cards (i.e.,
6081RC, 3096RC, 6511RC, etc.) have access to all 32 ports on the bus.

Characteristics of the H.110 bus:

• The H.110 bus is partitioned into 32 ports.

• Each H.110 port can handle up to 128 timeslots, each timeslot is 64 kbps.

• H.110 timeslots are unidirectional, for a full duplex link timeslots need to be defined for each direction of

transmission.

• H.110 port numbers between two cards must match.

• Direction of transmission between two cards must complement each other.

Figure 6 shows an H.110 bus interconnection connection between a 6081RC and a 3096RC. Two maps are

necessary for a full duplex link; both maps must have the same number of timeslots in each direction. In addi­tion, the 6081RC H.110 port should connect to a corresponding 3096RC H.110 port. Similarly, the H.110
directions between the 6081RC and the 3096RC maps should complement each other, for example timeslots
in a “to H.110” port on the 6081RC, should go to timeslots in a “from H.110” port on the 3096RC.

Figure 6. H.110 port correspondence and direction

Defining H.110 channels

From the standpoint of the 6081RC, H.110 ports and timeslot are assigned to PPP channels. To configure
H.110 channels, do the following:

1. Click on the H.110 link in the Configuration Menu pane (see figure 4 on page 11) to display the

3 • Bridged data application Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

Introduction

In bridged Ethernet applications, the IpDSLAM, and EdgeRoute Network Access Server incorporated in Pat­ton ForeFront system, function as an Ethernet hub for interconnecting G.SHDSL access lines and an Ethernet
LAN. Functioning as a hub, they deliver data traffic to and from all interfaces (Subscriber ports and one Ether­net LAN interface) by means of Ethernet bridging at the data link layer—layer 2 of the Open Systems Inter­connection (OSI) model. The IpDSLAM and EdgeRoute Network Access Server use bridging control protocol
(BCP) to provide the bridging function. The IpDSLAM and EdgeRoute Network Access Server use point-to­point protocol (PPP) for data delivery across the G.SHDSL links, by encapsulating each BCP datagram in a
PPP frame.

Figure 11. Model 3324 bridged data application diagram

In general, network engineers may find the Ethernet bridging configuration useful for any data communica­tion system requiring long-range connections between remote devices and an Ethernet LAN at a central loca­tion. (See figure 11 for Model 3224 bridged data application diagram and figure 12 on page 19 for the Model
6081RC diagram.) As a more specific example, a bridged Ethernet solution may be used when implementing
such a real-world application as Internet Service for small and home based businesses. In such a scenario, mini
LANs supporting from 1 to 50 users would be connected via a G.SHDSL line to the IpDSLAM, and EdgeR­oute Network Access Server (using 3096RC cards), which would then provide bridged communications with
servers and Internet gateways connected to the main LAN.

Figure 12. Model 6081RC bridged data application diagram

Introduction 19

3 • Bridged data application Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

Basic assumptions

The bridged Ethernet network is based on the following basic assumptions:

• Ethernet Interface A (Rear panel 3224, front panel 6081RC)

- You will connect a management workstation (such as a PC) to the IpDSLAM or EdgeRoute Network

Access Server Ethernet Interface A.

- You will use the management workstation on Interface A to configure the IpDSLAM or EdgeRoute Net-

work Access Server using a web browser.

Figure 13. Port connectors

Note Your workstation must reside within the same IP subnetwork as

Ethernet Interface A in order to connect to the IpDSLAM or EdgeR­oute Network Access Server management interface via the factory­default IP address, which is 198.168.200.98. In other words, the first
three octets of your workstation’s IP address must be 198.168.200.

20 Basic assumptions

Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide 3 • Bridged data application

Note Once the IpDSLAM or EdgeRoute Network Access Server have been

configured for operation, you may wish to connect Ethernet Port A to
the LAN. Doing so offers the following advantages:

• Remote management—you can log in to the IpDSLAM and Edg-

eRoute Network Access Server management interface remotely using
any workstation connected to the LAN and standard http browser.

• Multiple operators—two or more operators can manage the IpD-

SLAM and EdgeRoute Network Access Server, at the same time or
at different times, using multiple workstations on the LAN.

Before moving Ethernet Port A to the LAN, you must first assign an
IP address to Ethernet Port A that has the same network number as
the LAN. For further instructions, see section“Modifying the IP

address for Ethernet interface A (optional)” on page 24.

• Ethernet Interface B (front Panel, Model 3224, front panel PMC module 6081RC)

- You will connect the IpDSLAM or EdgeRoute Network Access Server Ethernet Port B to an

Ethernet LAN.

Note This procedure assumes that the Model 6081RC is equipped with a

PMC card which presents Ethernet port B on the front panel of the
unit. Units not equipped with a PMC card have both Ethernet ports
B and C internally connected to the ForeFront Chassis midplane.

It’s possible to use the model 6081RC Ethernet port A simulta­neously for bridging and management (see section “Alternate Inter-

face Configuration for Model 6081RC” on page 31 for details.)

- All traffic on Ethernet Port B will be delivered via Ethernet bridging at layer 2 of the OSI model.

- No IP address will be needed by or assigned to Ethernet Port B.

Defaults

The bridged Ethernet configuration described in section “Basic assumptions” operates using the 3224 default
values. For the Model 6081RC, the operator must configure H.110 port parameters and create PPP transport
and bridge groups.

• Ethernet Interface A—By factory default the IP address assigned to Ethernet interface A for both model

3224 and 6081RC is 192.168.200.98/24 ( the designation /24 indicates the IP address has a netmask of

255.255.255.0)

• Ethernet Interface B—By factory default Ethernet interface B for both 3224 and 6081RC is not assigned

an IP address. In bridged data application, because this Ethernet interface is intended to handle bridged
traffic only, no IP address is needed

• Ethernet Interface C (6081RC only)—By factory default Ethernet interface C in the 6081RC is not

assigned an IP address. This Ethernet interface is not used in this particular application

Transport Defaults 3224:

Defaults 21

3 • Bridged data application Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

• 3224 G.SHDSL ports 1-24—All 24 G.SHDSL ports are factory configured with the following defaults:

- PPP Mode = BCP (bridging control protocol)

- G.SHDSL Annex = B—Annex B is typically used in most countries, while Annex A is used in

North America

- G.SHDSL speed = 2.034—This setting corresponds to a speed of 2.304 Mbps

- Enable = checked—This value enables the Ethernet bridging function on the port

Transport Defaults 6081RC:

• 6081RC H.110 ports 1-32 - Factory default un-configured – operator must define H.110 ports and PPP

channels.

- PPP Mode (BCP, IPCP) = un-configured—Operator must define PPP/H.110 channels.

- Bridge group = un-configured—Operator must first define bridge group, and then attach all ports (Ether-

net, H.110) for bridging.

- H.110 ports = un-configured

- H.110 port speed = un-configured

- Defined

CPE configuration

The Patton Model 3201 Router Modems used in the Bridged Ethernet network described above must be fac­tory-configured in CP mode (as opposed to CO mode). If any Model 3201 used in this network is factory-con­figured in CO mode, you must re-configure the device for CP mode. For more information on configuring the
Model 3201, refer to the Model 3201 Getting Started Guide or Administrator’s Reference Guide that shipped
with the device.

Initiating bridged Ethernet data communications

Once you have made the connections shown in figure 1 on page 3, you need only power up the IpDSLAM and
the connected Model 3201 CPE devices for the bridged Ethernet network to begin operation and start carry­ing data traffic. The rest of this section describes the procedures for modifying the IpDSLAM’s factory default
configuration for bridged data application.

Modifying the factory default configuration

Modifying the IpDSLAM’s factory-default configuration comprises the following major tasks:

• Modifying the IP Address for Ethernet Interface A (if desired) (see section “Modifying the IP address for

Ethernet interface A (optional)” on page 24)

• Configuring the G.SHDSL port(s) (Model 3224) (see section “Configuring Model 3224 G.SHDSL param-

eters” on page 11)

Logging in using the factory-default IP address

Your workstation must reside within the same IP subnetwork as Ethernet Interface A in order to connect to the
IpDSLAMs management interface via the factory-default IP address, which is 198.168.200.98. That is, the
first three octets or your workstation’s IP address must be 198.168.200. Using a workstation connected to the
IpDSLAM’s Ethernet Interface A, do the following:

1. Power up the workstation and open a standard HTTP browser (such as Microsoft Internet Explorer or

Netscape Navigator).

2. In your browser’s address field, enter 192.168.200.98 (the default IP address for the IpDSLAM’s Ethernet

Interface A), then press the <enter> key. The login popup window (see figure 14) will appear on your
screen.

Modifying the IP address for Ethernet interface A (optional)

You may wish to connect Ethernet Port A to the LAN in order to enable remote management and multiple
operator capabilities described below:

• Remote management—You can log in to Ethernet port A remotely using any workstation connected to the

LAN and standard HTTP browser.

• Multiple operators—Two or more operators can manage the Model 3224 or Model 6081RC, at the same

time or at different times, using multiple workstations on the LAN.

Before connecting Ethernet Port A to the LAN, you must first assign an IP address to Ethernet Port A that has
the same network number as the LAN. To modify the IP address, do the following:

1. On the menu pane at the left side of the web management home page (see figure 15), click the Interface

hyperlink. The

Interface Configuration window will appear (see figure 17).

Figure 17. Interface configuration window

2. Use the drop down menu to select Ethernet A. Enter the new IP address for Ethernet A in the IP Address

field for Interface A. The new IP address must have the same network number as the Ethernet LAN to
which you intend to connect Interface A.

3. In the

NetMask field for Interface A, enter the netmask for the new IP address you have chosen.

5. Type a short description for Bridge 1 in the

Description text box.

6. Aging time is the number of seconds a MAC-address will be held in the forwarding database after receiving

a packet from this MAC address. The entries in the forwarding database are periodically timed out to
ensure they won’t stay around forever. If desired, type a value (in seconds) for the forwarding table aging
time in the

Aging Time box. The default value for this setting is 300 seconds (5 minutes).

7. The 3224 and 6081RC periodically check the forwarding database for timed-out entries which are then

deleted. The

Garbage Collection Interval is the time (in seconds) that between each checks of the forward-

ing database.

8. Spanning tree is a link management protocol that provides path redundancy while preventing undesirable

loops in the network. For a Layer 2 Ethernet or Token Ring network to function properly, only one active
path must exist between two stations. Spanning-tree operation is transparent to end stations, which cannot
detect whether they are connected to a single LAN segment or a switched LAN of multiple segments.

If you will not be enabling Spanning Tree options, go to step 9. Otherwise, click the

Enable Spanning Tree

box to activate Spanning Tree Options. The following options are available for configuration:
– Priority: The switch with the highest bridge priority (the lowest numerical priority value) is elected as

the spanning-tree root switch, which is the logical center of the spanning-tree topology in a switched
network. If all switches are configured with the default priority (32768), the switch with the lowest
MAC address in the Layer 2 network becomes the root switch. Under some circumstances, traffic pat­terns may require that a different switch be assigned as the root switch than that which was chosen by
default. Increasing the priority by typing a number in the Priority box that is less than the default 32768
value forces the switch to become the root switch.

– Forward Delay: This value is the time a port will remain in the listening and learning states before enter-

ing the forwarding state.

– Hello Time: The amount of time a port will remain in the listening and learning states before entering

the forwarding state.

– Max Message Age: The length of time the switch will store protocol information received on a port.

9. Once all options have been entered, click the Submit button to save changes.

PPP channel configuration

The Models 3224 and 6081RC generate PPP channels to transport bridged (BCP) or routed (IPCP) data to
and from subscriber’s premises.

In the case of the Model 3224, PPP channels are created automatically and each channel is assigned to a
G.SHDSL port. For example PPP channel 1 is assigned to G.SHDSL port 1, PPP channel 2 is assigned to
G.SHDSL port 2, etc.

In the case of the 6081RC, a PPP channel is generated automatically only when the operator creates a H.110
channel. When an H.110 channel is created, it automatically receives a sequential ID number starting at 1.
Consequently, the corresponding PPP channel is also assigned the same ID number. For example, PPP Chan­nel 3 is attached to H.110 channel 3.

PPP channel configuration 27

3 • Bridged data application Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

Additionally, if a PPP channel is to transport bridged data a BCP interface is created (see section “Interface

configuration” on page 30), the BCP interface also takes the PPP channel number, for example BCP3 interface

corresponds to PPP channel 3, which in turn is attached to H.110 channel 3 (6081RC) or to the G.SHDSL
port 3. The same is true for routed connections (IPCP).

Figure 22. Model 3224 bridged PPP channel and interfaces

Figure 23. Model 6081RC bridged PPP channel and interfaces

The PPP channel configuration page allows assignment of bridged or routed sessions to DSL or H.110 ports,
as well as definition of PPP link parameters such as MRU, retry times, authentication, etc.

At this time, a PPP/BCP connection between the 3224 or 6081RC and the remote CPEs may have been estab­lished (check this by clicking on the PPP main menu option), each PPP connection will be displayed in color
code, the color green meaning that a connection has been established. However, there is not yet a connection
between the PPP/BCP modules and the Ethernet port (that is, the bridge module does not have a path to the
Ethernet port and therefore no bridged data can be sent to the LAN). To activate a connection between the
bridge module and the front panel Ethernet interface (Ethernet B), do the following:

1. In the

Ethernet B row (see figure 27 on page 30), click to add a checkmark on the box under the Enabled

Introduction

The Models 3224 and 6081RC support vLAN (802.1Q) connections between remote users and a central loca­tion. To create a VLAN connection for bridged PPP connections, each PPP connection is attached to a bridge
connected to a separate virtual Ethernet interface. Finally, each virtual interface is attached to a physical Ether­net port as shown in figure 32).

Figure 32. VLAN connection diagram

Packets arriving from the remote CPE will be tagged with VLAN information and sent to the Ethernet port.
VLAN packets received from the LAN by the Ethernet port of the 3224 or 6081RC and corresponding to the
remote CPE, will be stripped of VLAN information and passed to the bridge module for transmission to the
remote CPE.

To create VLAN connections, do the following:

1. On the model 3224, Configure G.SHDSL Channels (see section “Configuring Model 3224 G.SHDSL

parameters” on page 11 for details). On the Model 6081RC, configure H.110 channels (see section “Con-
figuring Model 6081RC H.110 parameters” on page 12” for details)

2. Create a bridge group (see section “Creating a bridge group” on page 25).

3. Configure PPP channel parameters (see section “PPP channel configuration” on page 27).

4. Attach a VLAN ID to an Ethernet interface (see section “Attaching a VLAN ID to an Ethernet interface”

on page 36).

5. Attach the bridge/PPP to the VLAN module (see section “Attaching a bridge interface to a VLAN mod-

ule” on page 37).

5 • Routed application using RIP Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

Introduction

The 3224 and 6081RC include powerful routing engines which enable network engineers to implement flexi­ble bridged or routed applications. Routed links can be configured using Static, RIP (Routing Information
Protocol), or OSPF (Open Shortest Path First) protocols. This applications document addresses configuration
steps needed for routed links using RIP.

Network diagram

The RIP Application can be implemented using either a Model 3224 or 6081RC, at a central location (Central
Office or ISP location), while remote locations use Patton’s Model 3201.

Up to 24 remote sites can be connected via DSL lines when using the Model 3224, and up to 128 customer
connections are possible using one 6081RC in combination with 3096RC cards. For the purpose of this appli­cation it is assumed that the 3224 or 6081RC reside in a different network than the 3201s at remote locations.

Customer data at remote locations is routed by the corresponding 3201 and sent via the DSL link to the cen­tral location. The central site model 3224/6081RC routes received data from incoming DSL (3224) or H.110
ports (6081RC) and route to Ethernet port A (IP address 192.168.200.98). Remote users reaching the central
LAN via DSL links can now access e-mail servers, web hosting servers, or an Internet gateway.

3224/6081RC configuration

Configuring the 3224 or 6081RC for this application includes the following steps:

1. Ethernet port A IP address configuration (see section “Ethernet port A IP address configuration” on

page 41)

2. Configuring G.SHDSL Parameters (3224 only) see section “Configuring G.SHDSL parameters (3224

only)” on page 41)

3. Configuring H.110 ports (6081RC only) see section “Configuring H.110 ports (6081RC only)” on

page 41)

4. Configure PPP global and channel configuration (see section “PPP global and channel configuration” on

page 41)

5. Configure RIP (see section “RIP configuration” on page 45)

6. Testing the link (see chapter 7, “Verifying operation” on page 53)

configuration

The Model 3224 and 6081RC PPP Configuration page is accessed from the main menu. Click on the PPP link
in the

Configuration Menu pane to reach the PPP page (see figure 38).

The PPP status window provides at-a-glance view of PPP channel/transport status, as well as links to Global,
Configuration, Multilink, Channel, and G.SHDSL (3224) or H.110 (6081RC) configuration pages.

Global configuration

Before configuring a PPP channel, it is necessary to create a pool of IP addresses. Addresses from this pool will
be later assigned automatically or manually by the user, to the local and remote PPP links (these are WAN IP
addresses for the PPP interfaces at each end of the link).

3224/6081RC configuration 41

To enter an IP address pool do the following:

1. Click on the Global link at the top of the page.

2. Enter the IP address pool information in

IP Options, IP Address Pool window,

3. Use IP Address 192.168.254 in this example. The 3224/6081RC will grab two consecutive addresses

beginning at 192.168.254.0 from this pool for each PPP channel connection, one for the local PPP inter­face and one for the remote PPP interface.

4. Leave all other settings for PPP, BCP, LCP and IPCP in this page in their default states.

clicking on the box corresponding to the IPCP option.

Next check the box corresponding to the Enabled option.

This window also offers the option for passive or active PPP. Leave the Passive box unchecked (active PPP
mode) to allow the 3224 to immediately start sending PPP configuration frames to the device connected to
this channel. Check the Passive box only if you would like the 3224/6081RC to wait for the remote device to
start sending PPP negotiation frames.

LCP options

LCP packets establish, maintain, and tear down a PPP session.

1. LCP Echo Failure—Use default. Number of outstanding consecutive echo requests sent by this device and

not answered by the remote device before assuming the remote peer is dead and connection is terminated.
Default is 10.

2. LCP Echo Interval—Use default. Time between echo requests send to the remote device. Default is 5 sec-

onds

3. LCP Max Configure—Use default. The maximum number of Configure-Request packets sent without

receiving a valid Configure-Ack, Configure-Nak or Configure-Reject before assuming that the peer is
unable to respond. Max-Configure should use the default of ten 10 transmissions.

5 • Routed application using RIP Models 3224 G.SHDSL IpDSLAM & 6081RC NAS Applications Guide

4. LCP Max Terminate—Use default. Indicates the number of Terminate-Request packets sent without

receiving a Terminate-Ack before assuming that the peer is unable to respond. Max-Terminate should use
the default of two transmissions.

5. LCP Max Failure—Use default. Number of LCP configure-nak responses to send before responding with

LCP configure-reject. This is to avoid endless negotiations that are obviously not leading to an agreement.
The 3224/6081RC defaults to 10.

6. LCP Restart—Use default. The Restart timer is used to time transmissions of Configure-Request and Ter-

minate-Request packets. Expiration of the Restart timer causes a Timeout event, and retransmission of the
corresponding Configure-Request or Terminate-Request packet. LCP Restart should use the default to
three seconds.

Multilink options

Not used for this application.

IP options

IP options allow assignment of an IP address for the local PPP interface. PPP/IPCP negotiation requires IP
addresses for the local and far end link; these addresses can be entered manually or left open for negotiation by
the IPCP layer. The IP addresses have local significance only (between the local and remote ends of the PPP
link).

1. Local IP Address—Use default IP address assigned by the 3224 from the IP global pool

2. Remote IP Address—Use default IP address assigned by the 3224/6081RC from the IP global pool

3. Peer Proxy ARP—Check this option to allow the 3224/6081RC to respond to address resolution protocol

requests on behalf of all IP addresses belonging to PPP users.

IPCP options

In some instances the local and remote devices may allow to negotiate IP addresses for the PPP/IPCP session.
In most cases with the 3224/6081RC both the local and remote IP addresses will be preconfigured.

1. IPCP Accept Local IP Address—Use default. Check this box only if the 3224/6081RC will be allowed to

accept a local IP address assigned by the remote device.

2. IPCP Accept Remote IP Address—Use default. Check this box only if the 3224/6081RC will accept

address taken (or assigned manually at the remote end) by the remote device.

3. IP Max Configure—Use default. The maximum number of Configure-Request packets sent without

receiving a valid Configure-Ack, Configure-Nak or Configure-Reject before assuming that the peer is
unable to respond. Max-Configure should use the default of 10 transmissions.

4. IP Max Terminate—Use default. Number of Terminate-Request packets sent without receiving a Termi-

nate-Ack before assuming that the peer is unable to respond. The 3224/6081RC default is three transmis­sions.

5. IP Max Failure—Use default. Maximum number of IP configure-nak responses to send before responding

with LCP configure-reject. This is to avoid endless negotiations that are obviously not leading to an agree­ment. The 3224/6081RC defaults to 10.

RIP timers

1. Update—Use default of 30 seconds. Every 30 seconds, the output process is instructed to generate a com-

plete response to every neighboring gateway.

– Timeout—Use default of 180 seconds. The timeout is initialized when a route is established, and any

time an update message is received for the route. If 180 seconds have passed since the last time the time­out was initialized, the route is considered to have expired, and route deletion process is started.

– Garbage Collection—Use default of 120 seconds. Deleted routes (due to timeout) are retained in the

table for a short time, so that neighbors can be notified that the route has been dropped. Upon expira­tion of the garbage-collection timer, the route is finally removed from the tables.

– Route Redistribution: Default Metric—Use default 1. Metrics used when redistributing routes.

Introduction

The following example uses a Model 3201 as the remote site router. Configuring the Model 3201 for RIP
application will involve the following steps:

• Ethernet port IP address configuration

• Ethernet Port IP Address Configuration

• G.SHDSL Layer Configuration

Ethernet port IP address configuration

Since this is a routed connection, the 3201 will most likely reside in a different network than the 3224 or
6081RC. Assign IP address 192.168.254.10 for the Ethernet interface of the model 3201 either through the
console port or the web interface (refer to the Model 3201 User Guide for more information)

G.SHDSL layer configuration

The 3201 ships from the factory set to operate in Remote (slave) mode, while the 3224 and 6081RC operate
always in Central mode (master), in this arrangement, the 3201 will accept (during link negotiation phase)
G.SHDSL configuration—such as speed—from the Model 3224. The only setting that is not accepted by the
3201 during link negotiation is annex mode. Configure the annex mode manually for annex B to match annex
mode on the Model 3224, otherwise the two units will not link up.

PPP layer configuration

1. Click on the Services Configuration in the Configuration Menu pane to reach the WAN Services Connec-

tions page. In the WAN connections menu page, click on the Create a new service link.

Figure 42. 3201 WAN Connections Configuration page

2. At this page, select the PPP routed service and click on the Continue button.
