Chapter 1
Introduction to Nokia M11

Nokia M11 is an ADSL (Asymmetric Digital Subscriber Line) modem
which enables high-speed Internet access and LAN (Local Area
Network) interconnection. It increases the capacity of the already
installed telephone lines used traditionally for telephone services.
M11 enables high-speed connections for residential users, small
offices and telecommuters.

remote IP network via a Digital Subscriber Line Access Multiplexer
(DSLAM) and an ATM access network. M11 can also act as a bridge
between the Ethernet LAN and ADSL/ATM network interfaces. M11
is compatible with Nokia D DSLAM.

The ADSL transmission is based on a DMT (Discrete multitone) line
code and it provides speeds up to 8 Mbit/s downstream (from the
network) and 1 Mbit/s upstream (to the network). M11 can adjust its
speed to the line conditions in steps of 32 kbit/s, maximising the data
throughput over the given distance. Nokia M1 1 is compatible with the
existing and emerging ADSL standards: ANSI T1.413 Issue 2 (ANSI
ADSL), ITU-T G.992.1 (ITU-T ADSL), ITU-T G.992.2 (ITU-T
ADSL Lite), and ITU-T G.996.1 (Handshake).

M11 provides optimised access to high-speed data services. It can be
used to connect telecommuters to the corporate network or netsurfers
to the Internet Service Provider’s (ISP) network, for example.

As a default, M11 supports plug-and-play operation for Internet access
applications. The ADSL connection, data connection and Internet
network addresses are set up automatically.

M11 has an integrated W eb server which enables configuring the most
frequently used parameters with an ordinary Web browser. M11 can
also be managed through a command line interface via telnet protocol
or via local console interface.

An external POTS (Plain Old Telephone System) filter enables the
simultaneous use of the conventional telephone service and the ADSL
data services.

Chapter 2
Applications and features

This chapter introduces the most common applications, features and
management method options of M1 1.

2.1 Applications

M11 has three main applications:

D Internet access
D Remote work
D LAN interconnection

In these application examples M11 can act as a router , bridge or NAPT
router . The selected mode for every single application depends on the
access and service provider network architectures. Some basic
application examples are described in this chapter. See Chapter 6 for
more information on routing, bridging and Network Address Port
Translation.

2.1.1 Internet access using M11 as a NAPT router

M11 can connect your PC via your operator’s Digital Subscriber Line
Access Multiplexer (DSLAM) and ATM network to an Internet
Service Provider (ISP). If you are connected to a single ISP, the
network addresses (IP addresses) in your home can be part of the ISP’s
IP address range. However, in many cases it is more practical that the
home network is an independent network utilising private IP addresses
which are not visible to outside and that M11 has only one external IP
address received from the ISP. The external Internet services are

accessed through this single IP address. This mode of operation is
called the Network Port Address Translation (NAPT).

The benefits of NAPT are the minimum coupling of the ISP and the
home network, the saving of public IP addresses, and in-built simple
firewall functionality .

2.1.2 Remote work

In a typical remote work application M11 is used as an IP router to
provide access to corporate Intranet services. Using routing between
the home and the corporate networks prevents unnecessary broadcast
traffic and non-IP protocol traf fic from loading the access connection
Still, it provides sufficient transparency for Intranet applications. The
M11 routing table can be static or it can be updated dynamically using
RIP version 1 and RIP version 2 routing protocols.

2.1.3 LAN interconnection using M11 as a bridge

LAN interconnection between corporate headquarters and its remote
office is another typical M1 1 application. In the LAN interconnection
application, M11 is typically used as an Ethernet bridge which relays
all non-local Ethernet traffic between the corporate headquarters and
remote sites through the ATM core network.

The benefit of bridging in this application example is the transparency
for all network protocols in a multiprotocol data communications
corporate network.

2.2 Features

M11 can operate as an OSI layer 3 Internet Protocol (IP) router
between the Ethernet interface and the virtual channels of ADSL/A TM
interface. M11 supports both dynamic and static routing.

It can also operate as a self-learning bridge supporting up to 256 MAC
addresses.

M11 supports IGMP (Internet Group Management Protocol) proxy
function for IP multicast applications.

Routing

Routing is based on routing entries in a routing table. Static routes are
added via the management interface and dynamic routing is done using
RIP and RIPv2. Routing is done between the Ethernet 10Base-T
interface and the virtual channel connection (VCC) of the A TM/ADSL
interface. Optionally, the routing between the VCCs can be disabled.
M11 supports up to 8 simultaneous VCCs.

Bridging

Bridging is supported to provide full protocol transparency . Bridging
can be used simultaneously with IP routing. M11 works as a
self-learning bridge supporting up to 256 MAC addresses. Bridging is
done between the Ethernet 10Base-T interface and each ATM VCC
interface. Optionally , the bridging between the VCCs can be disabled.
M11 supports up to 8 simultaneous VCCs.

Network Address Port Translation

M11 supports Network Address Port Translation (NAPT) for TCP/IP
and UDP/IP protocols. When NAPT is used, a single IP address is
allocated to a VCC which leads to the public IP network. The Ethernet
subnet has private IP addressing and is not visible to the VCC. NAPT
translates the IP source address and source port number dynamically to
the VCC IP address and port number. Similarly, packets coming from
the VCC are mapped back to the original destination addresses. NAPT
allows up to 253 hosts to share a single VCC IP address to the public
network. The Network Address Port Translation principle is presented
in Figure 2-4.

NAPT may restrict the operation of some IP applications. NAPT also
operates as a simple IP firewall because translation is only allowed
when the first packet is transmitted from the LAN. This means that the
NAPT table entry is created only when a packet is sent from the home
network to the Internet. W ith pinhole capability , the user can add static
entries to the NAPT table allowing the translation always in both
directions. This capability is used to add servers (HTTP, NNTP, and
FTP), which are visible to the public IP network via the VCC, on the
LAN subnet.

Dynamic Host Configuration

M11 can act as a Dynamic Host Configuration Protocol (DHCP)
server for the PCs on the end-user home network. In this mode, M11
can assign up to 253 IP addresses to the PCs on the home network. M11
can also act as a DHCP relay agent and relay the DHCP requests to an
external DHCP server.

ATM and ADSL

M11 supports up to 8 simultaneous VCCs and supports UBR
(Unspecified bit rate) traffic shaping on all VCCs. The maximum
transmit rate on each VCC is the ADSL upstream capacity. If more
than one VCC is transmitting simultaneously, the ADSL upstream
capacity is temporarily shared between these VCCs. When one VCC is
idle, the bandwidth is used by another VCC. M11 also supports limited
CBR on upstream (see Transmit priority selection in this chapter).

The ADSL transmission is based on the DMT line code. M11 provides
a DMT line rate up to 8 Mbit/s downstream and up to 1 Mbit/s
upstream. The DMT transceiver is rate adaptive and capable of
providing faster rates over short distances or slower rates over long
distances. The transceiver adapts itself to the line conditions. M11
supports also ADSL Lite. In the ADSL Lite mode, the maximum line
rates are 1536 kbit/s downstream and 512 kbit/s upstream.

The A TM over ADSL transmission is based on ITU-T G.992.1. ADSL
Lite is based on ITU-T G.992.2.

Rate adaptation is done in steps of 32 kbit/s. The ADSL interface of
M11 functions completely automatically and all configuration related
to the ADSL connection is done at the access multiplexer in the
operator’s premises. The network operator can set the data rates as a
part of the network management functionality provided by Nokia D
DSLAM.

Payload encapsulations

Both routed and bridged protocols are encapsulated in the A TM link by
using either RFC 1483 LLC/SNAP encapsulation or VC multiplexing.
M11 also supports PPP over AAL5 encapsulation, in which both
bridged and routed protocols are first encapsulated in PPP (RFC 1661).
PPP is then encapsulated in ATM according to the IETF PPP over
AAL5 using RFC 2364 VC multiplexing or LLC/NLPID
encapsulation.

See Chapter 6 for more information on the payload encapsulations.

T ransmit priority selection

If you are using more than one upstream connections, you can set
priorities to these connections. You can also set the maximum transmit
rate to the connection. The following example explains the transmit
priority selection:

Connection Priority Maximum transmit

rate

VCC1 HIGH 400 kbit/s
VCC2 LOW 0 (no limit)

Table 2-1 Transmit priority selection example settings

The settings shown in T able 2-1 affect the connections in the following
way:

D When VCC1 is not transmitting, VCC2 can use the whole

bandwidth.

D When VCC2 is not transmitting, VCC1 gets only 400 kbit/s even if

there was more bandwidth available on the upstream link.

D When VCC1 starts transmitting, it gets 400 kbit/s bandwidth and

VCC2 gets the rest of the available bandwidth.

D If the upstream bandwidth is 400 kbit/s and VCC1 uses 400 kbit/s,

VCC2 can not transmit anything until VCC1 starts to transmit less
than 400 kbit/s.

IGMP proxy function

M11 can be used as an IGMP proxy which means that M11 can send
IGMP queries and have IP hosts report their IP multicast host group
memberships. See Chapter 6 for more information about IP multicast.

Management

There are four management methods in M1 1:

D Command line interface (CLI) through console serial port
D CLI via telnet
D SNMP
D Web browser management

The CLI allows complete configuration of the unit; the Web browser
management allows the configuration of the most frequently used
configuration parameters. SNMP can be used to read some equipment
identity information and to provide traps for authentication failures.

2.2.1 Dedicated management channel

The operator or Internet Service Provider can establish a dedicated
management channel to M1 1. This channel provides access to the M11
management (with telnet or W eb browser) and it can be used to upload
a new software to M11. When the management channel is in use it
prevents data traffic between the management channel and the
Ethernet as well as the traffic between the management channel and
other active ATM channels. Figure 2-5 shows the principle of the
dedicated management channel.

In Figure 2-5 VCC1 is used for customers data transmission.
Administration through this channel has been disabled. The operator
or the service provider uses the VCC2 for management purposes only .

Chapter 4
Installing M11

This chapter presents step-by-step installation example procedures for
three different application examples of Nokia M11:

D Internet access (NAPT router)
D Remote work (basic router)
D LAN interconnection (basic bridge)

These installation procedures are examples to guide you through some
of the typical use cases.

In the installation examples, we assume that you have a new M11 with
a factory default configuration. The complete default configuration is
presented in the end of this chapter. The default settings are, briefly:

D Single ADSL/ATM channel (VPI = 0, VCI = 100)
D PPP over ATM/AAL5 encapsulation
D M11 retrieves IP address configuration from IP network using

PPP-IPCP negotiation

D Network Address Port Translation activated
D Private IP addresses in use in LAN
D DHCP server for LAN interface activated

Before starting the installation, unpack the unit and check that it is
physically undamaged.

4.1 Internet access (NAPT router)

This application is based on the default configuration of the Nokia
M11. By default, Nokia M11 is an Internet access device that uses

The Internet access application requires that your PC uses Dynamic
Host Configuration Protocol (DHCP) to get its network address (IP
address) from your Nokia M11.

The installation procedure depends on whether you want to use data
services only or data and simultaneous telephone services. If you want
data services only, start from Step 1a. If you want both data and
telephone services, start from Step 1b .

M11 has an optional three-level password (user, user-admin, and
admin), which also affects the installation procedure. By default, the
password is disabled but it can be enabled through the command line
interface (see Chapter 5 Management). Steps 4b and 5b describe the
actions when password is enabled.

Step 1a: Connect cables (data services only)

Connect the following cables:

D Connect the mains power cord first to Nokia M11 and then to a

power outlet.

D Connect the Ethernet cross cable to the Nokia M11 ETH connector

and the other end to your PC’s Ethernet port.

D Connect the ADSL cable to the telephone socket.
D Go to Step 2.

Step 1b: Connect cables (data and telephone services)

If you want to use your telephone line for both the high-speed ADSL
service and normal telephone service, you must install a POTS filter .
You can use Nokia POTS filter T66130 or T66150. See separate
installation instructions for POTS filters.

Connect the following cables:

D Connect the mains power cord first to Nokia M11 and then to a

power outlet.

D Connect the Ethernet cross cable to the Nokia M11 ETH connector

and the other end to your PC’s Ethernet port.

D Connect the ADSL cable and the telephone according to the

separate POTS filter installation instructions.

D Go to Step 2.

Step 2: Switch on M1 1

The green STA indicator and red DSL indicator light up. After a while
the DSL light starts blinking, indicating that the connection is being
