2.3 HardWare Installation
☞ To install modem into PC, follow below steps.
1. Turn off your computer and all attached peripheral devices (printer, monitor,
etc.) and unplug them from the electrical outlet.
? CAUTION : To avoid risk of electric shock, make sure your computer and all
peripheral devices are turned off and unplugged.
2. Attach power supply to power inlet connector
3. Plug power supply cable into standard electrical socket.
4. Connect the RJ11 port to the modem( ) using the phone line
5. For Ethernet Modem installation, connect one end of the Ethernet cross-over
cable to the modem and the other end to the PC. If an Ethernet hub is being used,
a straight–through cable will be needed to attach the modem to the hub.
2.4 SoftWare Installation
☞ The modem has its software image stored in flash. The Ethernet bridge/router
image is stored in flash by default.
In order to use the modem, the modem will need to be configured as a bridge or
router. There is no installation of software on the PC for this, except for the
normal Ethernet LAN adapter installation.
The modem configuration can be viewed and modified through the console
which is accessible through the RS-232 serial connection. To use the serial
interface, a straight-through cable is needed between the modem and a terminal
(could be a PC running a terminal emulation package).
The PHY can be configured to attempt the layer 1 connection in one of the
following modes:
? T1.413
GARNET
GAE -3030
? G.Lite
? G.dmt
This is configured by setting the BUN attribute AdslMode with the following
console command:
bun set port atm/adslmode=
Where acceptable value of are, t1413, glite, gdmt.
Protocol Configuration for configuring the modem for this mode of operation.
2.5 Ethernet Bridge Configuration
In the Ethernet bridge configuration, the modem bridges data between the local
Ethernet LAN and the service provider. The ADSL link must be set up in RFC1483
mode with a PVC to communicate across. The PVC is assigned by the service
provider. The bridge needs to be told about both the Ethernet interface and the
1483 interface. Since the modem is transparent, the PC’s default gateway must
be set to the service provider’s IP address.
The following configuration must be performed to set up the modem for bridge
mode:
? Add the Ethernet device to the bridge:
Bridge device add edd
? Add the ADSL ATM port to the bridge with RFC 1483 enabled:
Bridge device add //bun/port=atm/txvci=32/rxvci=32/rfc1483=true
? Save the configuration and reboot the system:
config save
restart
2.6 Ethernet Router Configuration
There are multiple ways that routing can be set up depending on the
requirements from the service provider.
The following routing methods are described below:
IPoA Routing
GARNET
GAE -3030
PPP Routing
Routing using NAT (can be used with either IPoA or PPP)
2.7 IPoA Routing
When configured for IPoA, data is routed between Ethernet and Classical IP over
ATM (RFC1577). The IPoA data runs over a PVC between the modem and the
service provider. IP addresses, the PVC and the peak cell rate need to be defined
by the service provider. Since the modem is routing, an IP address needs to be
assigned on both modem’s interfaces. The PC’s default gateway must be set to
the Ethernet IP address of the modem. The following configuration must be
performed to set up the modem for the above example:
Add the Ethernet device to the router and assign it an IP address. In the
command, “ethernet” is a label used to refer to this device. The arguments
“ether” and “//edd” are required for an Ethernet device.
ip device add ethernet ether //edd 192.168.101.2
Add the IPoA device to the router and assign it an IP address. In the following
command, “ipoa” is a label used to refer to this device. The arguments “atmpvc”
and “//atm” are required for an IPoA device.
ip device add ipoa atmpvc //atm 192.168.102.2
Save configuration and reboot system. This is necessary when configuring
the system from the console, because the following commands can only operate
on router interfaces which have already been created.
config save
restart
Enable forwarding between the router interfaces:
ip relay all
Add a default route with the service provider as the gateway:
ip route add default 0.0.0.0 192.168.102.3 0:0:0:0
? The next command configures the IPoA protocol to run on PVC 700 with a
peak cell rate of 50000 cells per second, using the port named “atm”:
ip ipatm pvc add ipoa atm 700 pcr 50000
Save the configuration and reboot the system.
config save
GARNET
GAE -3030
restart
2.8 PPP Routing
When configured for PPP, data is routed between Ethernet and PPP over ATM.
The PPP data runs over a PVC between the modem and the service provider.
The IP address and PVC need to be defined by the service provider. Since the
modem is routing, an IP address needs to be assigned on both modem’s
interfaces. The PC’s default gateway must be set to the Ethernet IP address of
the modem.
The following configuration must be performed to set up the modem:
Add the Ethernet device to the router and assign it an IP address. In the
command, “ethernet” is a label used to refer to this device. The arguments
“ether” and “//edd” are required for an Ethernet device.
ip device add ethernet ether //edd 192.168.101.2
Add the PPP device to the router and assign it an IP address. In the following
command, “ppp_device” is a label for this device. The argument “ether” is
required for a PPP device. The PPP module supports multiple simultaneous
connections, so we explicitly specify Device 1.
ip device add ppp_device ether //ppp/DEVICE=1
We will be using PPP Device 1 and Interface 1, which are able to automatically
configure the IP address of the router interface and add a default route, when the
connection is made. That is why the IP address of the router interface was not
specified in the previous command.
? The following command configures PPP Device 1 for dial-out on PVC 700.
CHAP authentication will be used; PPP will supply a username of “fred” and a
password of “password”.
ppp 1 pvc 700 ip
ppp 1 welogin fred password chap
ppp 1 enable
Save the configuration and reboot the system. This is necessary when
configuring the system from the console, because the following command can
only operate on router interfaces which have already been created.
config save
10
GARNET
GAE -3030
restart
Enable forwarding between the router interfaces:
ip relay all
Save the configuration and reboot the system:
config save
restart
2.9 NAT
NAT can be used with IPoA routing or PPP routing. NAT has to be enabled on the
router interface towards the service provider.
The following command enables NAT on a router interface.
ip nat add
For the IPoA example previously described the command would be:
ip nat add ipoa
For the PPP example previously described the command would be:
ip nat add ppp_device
2.10 DHCP Server
DHCP can be used to assign IP addresses to PCs connected on the Ethernet
interface of the Client Access Device, as long as the Client Access Device has
been assigned an IP address. In addition to the commands shown in the next
sections, use the following command to get information on all of the DHCP
Server commands:
dhcpserver help
Enabling the DHCP Server
To enable the DHCP server, a range of IP addresses need to be provided that the
server can assign to clients.
The example below shows the commands needed to supply the DHCP server
with 99 IP addresses from 192.168.219.1 to 192.168.219.99 on the subnet
192.168.219.0 with the subnet mask of 255.255.255.0. The maximum lease time
for each client is set to 86400 seconds, or 1 day.
11
BOOTP clients may be
GARNET
GAE -3030
serviced, and requests from unknown clients are allowed.
The following configuration must be performed for the example:
Set up the DHCP configuration
dhcpserver
config add allow unknown-clients;
config add allow bootp;
config add subnet 192.168.219.0 netmask 255.255.255.0
config add {
config add range 192.168.219.1 192.168.219.99;
config add max-lease-time 86400;
config add }
config confirm
Save the configuration and reboot the system:
home
flashfs update
restart
Disabling the DHCP Server
To disable the DHCP server, the configuration information previously supplied
needs to be flushed. To do so, issue the following commands:
Flush the DHCP configuration
dhcpserver
config flush
config confirm
Save the configuration and reboot the system:
home
flashfs update
restart
Re-configuring the DHCP Server
To re-configure the DHCP server, issue the disable procedure followed by the
enable procedure.
2.11 Updating the Npimage
12
GARNET
GAE -3030
If the ATMOS image(s) have been corrupted and the Client Access Device has
booted in Recovery Mode, it may be necessary to update both the image and
NPimage files. If this is necessary follow the steps in section
2.2.1, copy the NPimage file from the Client Access Device CD to the same
directory as the other TFTP files, and run the following command:
tftp> put NPimage
Either instead of the command:
tftp> put image
or just after it. In other words, it is possible to update the NPimage separately
or during the same update as the image file.
2.12 PHY Flash Update
2.12.1 Updating the PHY flash code
Power-up the Client Access Device with the Ethernet cable connecting the
board to the house network.
If the console prompt does not show the board IP address see section 5.1 to
set the IP address.
? On the PC where TFTP is to be run, create a file called tftplock.key which
contains the text “password”.
Also create the files tftpupdt.beg and tftpupdt.end which contain the text “junk”
Copy the file tftpupdt.nof to the same directory the above files are located in.
From this directory run TFTP.
In TFTP, run the following commands:
tftp> connect 172.16.1.239 (substitute the IP address of the test board)
tftp> bin
tftp> put tftplock.key
tftp> put tftpupdt.beg
tftp> put tftpupdt.nof
tftp> put tftpupdt.end
From the Client Access Device console run the following commands:
172.16.1.239> bun adi super
172.16.1.239> bun adi update
13
GARNET
GAE -3030
The driver will display status information during the update procedure. Once
the update is completed turn the board off and then on again for the changes to
take effect. If there is an error in the update procedure, try turning the board off
and then on again and repeating the update process.
2.12.2 PHY Image Conversion Utility
It may be necessary to create the file tftpupdt.nof using the conversion utility
discussed below. When updating the PHY flash image, 3 files are used from the
PHY vendor. These 3 files are converted into 1 file to decrease the number of
files needed and the total file size required during the TFTP process.
If a single converted file is supplied, do not proceed with this step.
2.12.2.1 Files involved
The following files will be supplied by the PHY vendor:
File
Read File
Default Name
readfls.idm
Program File
progfls.idm
PHY Flash Image
rt.bnm
Description
This is the executable
code the PHY runs to
read the data from the
flash part.
This is the executable
code the PHY will run to
program data into the
flash part.
This is an S-record file
that contains the data to
be programmed into the
PHY flash part.
The default files names shown are what the conversion utility normally expects.
These can be changed using a command line argument.
The output file tftpupdt.nof will be created. This is the file to be used in the TFTP
update process.
2.12.2.2 Command line arguments
The PHY image conversion utility can be run as shown in the following table:
Runs the utility with the default file
names to be converted.
Displays the help/usage information.
phycon –h
phycon –f
2.12.2.3 Examples
Consider the case where the default file names are used. Run the utility from the
same directory the PHY files are located:
Example :
phycon –d Will use the default file names to generate
tftpupdt.nof
Consider the case where the files to use are readfls.idm, progfls23.idm, and
rt930a.bnm:
Example: phycon –f readfls.idm
progfls23.idm
rt930a.bnm Will use the
given file names to create tftpupdt.nof
2.13 VCI/VPI Value Configuration.
