2. Basics of the SDSL Bridge/Router
2.1 Introduction
Congratulations on your purchase of the SDSL Bridge / Router !
SDSL, which stands for Symmetric Digital Subscriber Line, featues the same high
data transmission rates both upstream and downstream. It is ideal to business
users as it enables them to take full advantage of applications (such as video
conferencing, LAN-to -LAN VPN connections and large file transfers) that require
high bandwidth in both directions.
The SDSL Bridge / Router offers faster and uninterrupted Internet access and is
capable of a data transmission rate up to 2.32 Mbps upstream and downstream.
This product is an embedded solution that is OS independent. It can be connected
to any computer with an Ethernet card. The Ethernet connection allows direct
interface to any existing IEEE 802.3 L AN network, providing instant broadband
Internet access to LAN networks with minimum hassle.
SDSL service providers can offer SDSL services to a multi-user business
environment with support for both Static and Dynamic IP Routing, Network
Address Translation and Dynamic Host Configuration Protocol Server.
This bridge/router features multiple data encapsulation formats for DSL transport
over ATM PVCs, including the widely supported ATM protocols RFC 1483 (MPoA),
RFC 1577 (IPoA) and RFC 2364 (PPPoA).
Utilising Conexant ZipWire
manufacturers, this bridge/router fur ther guarantees interoperability with network
providers worldwide.

3. Setting Up Local Management
Local management refers to the process of managing and configuring the settings
of your router for your network environment. It is done via a PC connected to
your router.
Before running local management, communication between your router and your
PC has to be configured and established for them to 'understand each other'. You
need to setup a physical link between your router and the PC via a serial cable
as described in Section 3.1. Section 3.2 will show you how to configure the
interface link to allow communication between your PC and your router.
Setting up of local management needs only to be carried out once

i) Configuring the WAN - For RFC 2684 (RFC 1483) Ethernet Framing
a) To add a bridge device, assuming the PVC given by your ISP is 0/35:
For LLC-SNAP encapsulation:
bridge device add //bun/port=sdsl/rfc1483=true/mode=llcbridged/
0
txvpi=
For VCMUX encapsulation:
bridge device add //bun/port=sdsl/rfc1483=true/mode=vcmuxbridged/

a) To set the IP configuration of your WAN connection, assuming the PVC
and WAN IP given by your ISP are 0/35 and 202.166.29.154 respectively:
For LLC-SNAP encapsulation:
ip device add wan ptp //bun/port=sdsl/rfc1483=true/mode=llcrouted/
0
txvpi=
ip subnet add wan.home .
/txvci=35/rxvpi=0/rxvci=35
202.166.29.154 ff:ff:ff:0
For VCMUX encapsulation:
ip device add wan ptp //bun/port=sdsl/rfc1483=true/
0
mode=vcmuxrouted/txvpi=
202.166.29.154
ip subnet add wan.home .
/txvci=35/rxvpi=0/rxvci=
(all in one line)
202.166.29.154 ff:ff:ff:0
For multiple PVCs,
- Repeat (a) with different PVCs values.
wan
- Append
with an underscore ('_') followed by a unique digit for
each of the different PVC configured.
- Issue a unique WAN IP for each of the different PVC configured
Examples:
For first PVC value (0/35)
append with a unique digit
ip device add wan_1 ptp //bun/port=sdsl/rfc1483=true/
mode=llcrouted/txvpi=
202.166.29.154
ip subnet add wan_1.home .
For second PVC value (0/100),
0
/txvci=35/rxvpi=0/rxvci=
(all in one line)
202.166.29.154 ff:ff:ff:0
append with a unique digit
ip device add wan_2 ptp //bun/port=sdsl/rfc1483=true/
0
/txvci=
mode=llcrouted/txvpi=
202.166.29.155
(all in one line)
ip subnet add wan_2.home .

iii) Configuring the WAN - For RFC 2225 (RFC 1577) IPoA
a) To set the IP configuration of your WAN connection, assuming the WAN
IP given by your ISP is 202.166.29.154:
ip device add wan atm //atm
ip subnet add wan.home .
202.166.29.154
202.166.29.154 ff:ff:ff:0
b) To set the WAN configuration, assuming the PVC and WAN Gateway
given by your ISP are 0/35 and 202.166.29.2 respectively:
ip ipatm pvc add wan sdsl
0/35
remoteip
202.166.29.2
OR
To obtain WAN settings automatically from your ISP:
ip device add wan atm //atm
ip ipatm pvc add wan sdsl
dhcp
0/35
remoteip
202.166.29.2
iv) Configuring the WAN - For RFC 2364 PPPoA
You can do back-to-back connection by setting up one router as CO and
another as CPE. To set up your router as CPE, do the following a to c:
a) To set the IP configuration of your WAN connection. The PPP module
supports multiple simultaneously connections, so we explicitly specify
Device 1 here. (This is required for PPP dial-out session):
ip device add ppp_device ether //ppp/DEVICE=
1
b) To set the PPP channel configuration, assuming the PVC given by your
ISP is 0/35. CHAP authentication is used in this example. Replace
CHAP with PAP if you are using PAP authentication. ISP will supply the
myuserid and mypassword.
ppp 1 pvc
ppp
0 35
1
welogin
ip
myuserid mypassword chap
ppp 1 enable
c) To check the PPP connection every 10 seconds. (This is to allow the
PPP session to automatically re-establish itself after an SDSL link
disruption and re-connection.):
ppp 1 echo every 10

To set up your router as CO, do the following a to c:
a) To set the IP configuration of your WAN connection. The PPP module
supports multiple simultaneously connections, so we explicitly specify
Device 2 here. (This is required for PPP dial-out session):
ip device add ppp_device ether //ppp/DEVICE=
2
b) To set the PPP channel configuration, assuming the PVC and CPE WAN
IP given by your ISP are 0/35 and 202.166.29.154 respectively. CHAP
authentication is used in this example. Replace CHAP with PAP if you
are using PAP authentication. ISP will supply the myuserid and
mypassword.

ppp 2 enable
c) To check the PPP connection every 10 seconds. (This is to allow the
PPP session to automatically re-establish itself after an SDSL link
disruption and re-connection.):
ppp 2 echo every 10
d) For both CPE and CO:
If you do not want to enable NAT, you may enable the PPP IP
Unnumbered feature (availability will depend on your router package).
PPP IP Unnumbered allows you to enable IP processing on a serial
interface without assigning it an explicit IP address. The ip unnumbered
interface can 'borrow' the IP address of another interface that is already
configured on the router, thereby conserving network and address space.
(Assuming your LAN Subnet mask is ff:ff:ff:f8.)
