Each of these configurations assumes that the AM200s start in the factory default configuration. The AM200 can be returned to its factory default state by using the following CLI command:
--> system config restore factory ↵↵
6.1
SET ONE END TO CO
All configurations require one AM200 to be configured as a CO, and the other as a CPE. AM200 defaults to a CPE, so the first thing we must do is set one of the units to be a CO. This is done using the following CLI command:
--> am200 set interface local dslmode co ↵↵
6.2
LINE RATE
By default AM200 will rate adapt to the highest line rate it can achieve on the line it is connected to. The rate being used can be found by using the following command:
--> am200 show interface local currentlinerate ↵↵
Alternatively the line rate can be specified. The line rate should be set at the CO end only. See section 8.8 of this manual for instructions on how to set the line rate.

Bridging is the default mode of operation of the AM200.
Connect the AM200 over the transmission line to form the wide area link. Connect the LAN to the 'CO'
AM200 with a straight cable. Connect the PC to the 'CPE' AM200 with a crossover cable.
AM200s are supplied with a default address and subnet mask as follows.
IP address 10.254.254.253
Subnet Mask 255.0.0.0
The IP address of one of the AM200s will have to be changed so that the two don't clash. If the address clashes with something else on the network then both will have to be changed.
To change the IP address use the following CLI command:
--> ip set interface iplan ipaddress <ipaddress> <netmask> ↵↵
Where <ipaddress> is the desired IP address, and <netmask> is the desired subnet mask.
ATL User Guide
AM200 Modem
6.3.2 CHANGING AN AM200 FROM ROUTER TO BRIDGE
Probably the quickest way to change an AM200 to be a Bridge is to restore the factory default settings as described at the start of the section. Otherwise the following commands will configure the AM200 to be a bridge.
First remove the router configuration. Type in:-
--> ip clear interfaces ↵↵
--> ip clear routes ↵↵
--> ip clear riproutes ↵↵
Then add interfaces for each side of the bridge, e.g. "lan" for the Ethernet user port and "wan" for the DSL connection: Type in:-
--> bridge add interface lan ↵↵
--> bridge add interface wan ↵↵
Then attach the interfaces to the appropriate transports. Type in:
--> bridge attach lan ethernet ↵↵
--> bridge attach wan hdlc ↵↵
Finally to allow IP management of the unit, create an IP interface "iplan" and attach the bridge to the IP stack:
--> ip add interface iplan <ipaddress> <netmask> ↵↵
--> ip attachbridge iplan ↵↵

6.3.3 C0NFIGURATION AS A ROUTER
See the diagram below for an example configuration of AM200 being used as a router. AM200 defaults to be a bridge, so first we must clear the bridge configuration. Type in:

--> bridge clear interfaces ↵↵
--> ip clear interfaces ↵↵
Then we add IP interfaces for each side of the router, e.g. "lan" (the Ethernet user port) and "wan" (the DSL line interface).
--> ip add interface lan <ipaddress> <netmask> ↵↵
--> ip add interface wan <ipaddress> <netmask> ↵↵
For the example above the following commands would be used at the CO.
--> ip add interface lan 10.10.1.1 255.255.0.0 ↵↵
--> ip add interface wan 192.168.1.1 255.255.0.0 ↵↵
And at the CPE
--> ip add interface lan 10.11.1.1 255.255.0.0 ↵↵
--> ip add interface wan 192.168.1.2 255.255.0.0 ↵↵
Then attach the interfaces we have created to the appropriate transports.
--> ip attach lan ethernet ↵↵
--> ip attach wan hdlc ↵↵
ATL User Guide

Then, add a default route for the wan link using the command
--> ip add defaultroute gateway <ipaddress> ↵↵
For the example above the following commands would be used at the CO.
--> ip add defaultroute gateway 192.168.1.2 ↵↵
And at the CPE

7 SELECTING THE CIRCUIT CONFIGURATION
The term 'digital section' refers to the data link between the user ports of the connected AM200s.
In a standalone section, the AM200s provide the complete transmission system.
In a tandem section, the AM200s are used to extend an existing circuit or network port. To achieve synchronous data transfer, the CO AM200 must derive its timing from the circuit to which it is connected.
A Point-to-Point link requires two AM200s, one CO and one CPE.
The AM200 at one end of the digital section is selected to be a CO; the remote end is selected to be a CPE.
For a tandem section, the AM200 connected to the tandem section is configured as the CO.

CLI AUTO COMPLETE
You can use the tab key to auto-complete an entry. The CLI will compare your current partial entry against the list of possible complete entries, and find a match. If your partial entry matches more than one complete entry, you will have to carry on typing until your partial entry is unique.
The following example illustrates the auto-complete feature.
-->am (press Tab key)
As long as the partial entry is enough to uniquely identify a complete entry, then pressing tab will successfully auto-complete the entry. The CLI will respond with:
-->am200
If the partial entry is not enough to uniquely identify a complete entry, then pressing tab will auto-complete the entry up to a point, whereby you must continue typing in order for the partial entry to uniquely identify a complete entry.

8.11 BRIDGE
Probably the quickest way to change an AM200 to be a Bridge is to restore the factory default settings as described in section 8.13. Otherwise the following commands will configure the AM200 to be a bridge.
First remove the router configuration. Type in:
--> ip clear interfaces ↵↵
--> ip clear routes ↵↵
--> ip clear riproutes ↵↵
Then add interfaces for each side of the bridge, e.g. "lan" for the Ethernet user port and "wan" for the DSL connection: Type in:-
--> bridge add interface lan ↵↵
--> bridge add interface wan ↵↵
Then attach the interfaces to the appropriate transports. Type in:
--> bridge attach lan ethernet ↵↵
--> bridge attach wan hdlc ↵↵
Finally to allow IP management of the unit, create an IP interface "iplan" and attach the bridge to the IP stack:
--> ip add interface iplan <ipaddress> <netmask> ↵↵
--> ip attachbridge iplan ↵↵
See the diagram below for an example configuration of AM200 being used as a bridge.

--> ip clear routes ↵↵
--> ip clear riproutes ↵↵
--> bridge add interface lan ↵↵
--> bridge add interface wan ↵↵
--> bridge attach lan ethernet ↵↵
--> bridge attach wan hdlc ↵↵
--> ip add interface iplan 10.1.1.3 255.255.0.0 ↵↵

--> bridge clear interfaces ↵↵
--> ip clear interfaces ↵↵
Then we add IP interfaces for each side of the router, e.g. "lan" (the Ethernet user port) and "wan" (the DSL line interface).
--> ip add interface lan <ipaddress> <netmask> ↵↵
--> ip add interface wan <ipaddress> <netmask> ↵↵
For the example above the following commands would be used at the CO.
--> ip add interface lan 10.10.1.1 255.255.0.0 ↵↵
--> ip add interface wan 192.168.1.1 255.255.0.0 ↵↵
And at the CPE
--> ip add interface lan 10.11.1.1 255.255.0.0 ↵↵
--> ip add interface wan 192.168.1.2 255.255.0.0 ↵↵
Then attach the interfaces we have created to the appropriate transports. At both units type in:
--> ip attach lan ethernet ↵↵
--> ip attach wan hdlc ↵↵
Then, add a default route for the wan link using the command.
--> ip add defaultroute gateway <ipaddress> ↵↵
ATL User Guide
AM200 Modem
For the example above the following commands would be used at the CO.
--> ip add defaultroute gateway 192.168.1.2 ↵↵
And at the CPE
--> ip add defaultroute gateway 192.168.1.1 ↵↵
Finally, add a route back to the connection on the LAN using the command:
--> ip add route <name> <subnet> <netmask> interface lan ↵↵
For the example above the following commands would be used at the CO.
--> ip add route route1 10.10.0.0 255.255.0.0 interface lan ↵↵
And at the CPE
--> ip add route route2 10.11.0.0 255.255.0.0 interface lan ↵↵
After doing these changes you must enter the following command and press the return key to store your settings. Type in:
--> system config save normal ↵↵
Note: Wait for the CLI confirmation message before you switch off the AM200.

8.13 RIP
Rather than adding static routes you can use RIP to set the units to automatically detecting connected IP addresses. Type in the following commands at both units;
--> ip set interface <DSL ipaddress name> rip accept all ↵↵
--> ip set interface <DSL ipaddress name> rip send v2 ↵↵
--> ip set interface <Ethernet ipaddress name> rip accept all ↵↵
--> ip set interface <Ethernet ipaddress name> rip send v2 ↵↵
In the router example shown in section 8.11, rather than adding the static routes the routes can be learnt automatically by typing in the following commands at both the CO and CPE:
--> ip set interface wan rip accept all ↵↵
--> ip set interface wan rip send v2 ↵↵
--> ip set interface lan rip accept all ↵↵
--> ip set interface lan rip send v2 ↵↵
It can take around 20 to 30 seconds for the routes to be learned. You can check that the required routes have been learnt by typing in:
--> ip list riproutes ↵↵
In the router example, typing in the list riproutes command would generate the following response from the
CO unit:

-------------------------------------------------------------------------------------------
8.14 RESTORING FACTORY DEFAULT
The AM200 can be defaulted back to the original Factory default setting by typing:-
--> system config restore factory ↵↵
Wait for the CLI confirmation message before you switch off
Note: This will cause the IP address to be reset to the default setting.
8.15 SAVING CLI CHANGES
After doing any changes you must save the changes. The settings can be saved either in the ‘normal’ or backup’ file. To save the settings into the ‘normal’ file, enter the following command and press the return key.
Type in:
--> system config save normal ↵↵
Note: Wait for the CLI confirmation message before you switch off the AM200.
If you do not enter this command then any changes will be lost if the AM200 is switched off.
8.16 RESTORING TO SAVED SETTINGS
The AM200 can be set back to either of the two saved settings Use the following CLI command to set the
AM200 to the settings saved in the ‘normal’ file.
--> system config restore normal ↵↵
Use the following CLI command to set the AM200 to the settings saved in the ‘backup’ file.
--> system config restore backup ↵↵

The Manage DS0 screen (Figure 56) allows the user to enable or disable specific time slots. Placing a '1' in a time slot enables that timeslot once the applied button has been selected.Placing a '0' in a time slot disables that timeslot once the applied button has been selected.
Only the enabled time slots are transmitted by the line i.e. If a data rate of 1024Kbps is required, then only
16 time slots should be enabled, (16 * 64kbps = 1024kbps) the remaining 16 timeslots must be disabled.

10 SETTING UP USING THE LCD
The front panel menu system allows you to make all of the necessary changes via the three front panel buttons and the liquid crystal display. The commands show in each menu are identical to the CLI commands outlined in section 8.
On power-on, and after a button inactivity timeout, the LCD display will revert to a status display. The upper
LCD display line will show the product name, management mode and DSL mode, while the lower LCD display line will show the DSL and user port states (Up, Errored, Down or Disabled) in rotation.
AM200:Master:Co
Line:Up
This display, and some of the 'Show' sub-menu items, is refreshed automatically every two seconds.Pressing
any one of the three buttons will wake-up the LCD.
10.1 MENU STRUCTURE
The menu structure is hierarchical. The upper LCD display line shows the current menu level. If appropriate, the lower LCD display line shows one of the sub-menus available from the current menu level. The 'Up' and
'Down' arrow buttons are used to scroll between all available sub-menus. The 'Select' button is used to traverse to the sub-menu currently displayed on the lower LCD display line.
If sub-menus are available below the current menu level, the upper LCD display line will terminate with a ":" character.
Most menus have 'Show' and 'Set' sub-menus.The 'List' sub-menus are bottom-level sub-menus and list, on the lower LCD display line, all interfaces for the menu (usually "Local" and, if appropriate, "Remote").
10.1.1 SHOW SUB-MENUs
When a 'Show' sub-menu is entered, the available interfaces are listed on the lower LCD display line (usually
"Local" and, if appropriate, "Remote"). Once an interface has been selected (using the 'Select' button), the lower LCD display line will list one or more bottom-level items which can be chosen by the 'Select' button.
The upper LCD display line will then terminate with a ">" character, whilst the lower LCD display line shows the value of the item selected. In some cases, the 'Up' and 'Down' arrow buttons can be used to scroll between a number of values for the item. If there is only a single value, the 'Up' arrow button can be used to return to the previous menu level. If the item displayed is "setable", the 'Select' button can be used to jump directly to the 'Set' sub-menu for the item. All 'Show’ items are automatically refreshed if the value changes.
10.1.2 SET SUB-MENUs
When a 'Set' sub-menu is entered, the available interfaces are listed on the lower LCD display line (usually
"Local" and, if appropriate, "Remote"). Once an interface has been selected (using the 'Select' button), the lower LCD display line will list one or more bottom-level items which can be chosen by the 'Select' button.
The upper LCD display line will then terminate with a "=" character, whilst the lower LCD display line shows one of the available settings for the item selected. The 'Up' and 'Down' arrow buttons can be used to scroll between the settings and the 'Select' button used to chose.
Most sub-menus contain a "RETURN" menu option to allow the user to return to a higher-level menu.
Alternatively, pressing both the 'Up' and 'Down' arrow buttons simultaneously will navigate up to the previous menu level.

G703

10/100 BaseT
Bridge / Router
RS-232 Console Power AC or DC
Figure 71 System Block Diagram
The copper system is intended for operation on 2-wire local telephone network circuits, such as those meeting
BT EPS-9. It will operate satisfactorily on unloaded lines having a wide range of characteristics; bridge taps can be tolerated, dependent upon their characteristics. Although, the system requires a baseband circuit, a continuous loop at DC is not required. The system can transmit data at user port rates between 64k and 2.3M
on a single pair.
For the copper system, echo cancellation is used to eliminate the unwanted reflections of the transmitted signal from the receiver input.
The line is connected to the transmission circuit via a line transformer, which acts as a balun and provides isolation; there is surge protection across the transformer line connections. The transmission circuit utilises a custom IC and a number of proprietary components to perform the signal processing described above.

14.2 DSL TRANSMISSION FRAME
The transmission system operates in a bit pump mode. The DSL frame is sent over this 'data pipe'. The DSL frame contains the following
Sync word
Stuff bits
Stuff control bits
EOC channel
Customer data
14
134 ATL User Guide
AM200 Modem
The nominal DSL frame is always 6ms long, regardless of the transmission rate of the individual channels.
The DSL frame length is adjusted slightly by the use of stuff bits. There may be 4 stuff bits or 2 stuff bits per frame. The stuff bits are used to adjust the effective payload bandwidth of the DSL frame.
If the user rate clock is slightly quicker than the line rate clock then less stuff bits are sent. Alternatively, if the user rate clock is slightly slower than the line rate clock then more stuff bits are sent. This mechanism allows the line rate bandwidth to be adjusted to match the user rate bandwidth.
At the receive end, the rate at which the stuff bits arrive is used to recover the user clock.
G.SHDSL uses Trellis Coded Pulse Amplitude Modulation (TC-PAM). TC-PAM was chosen as the basis for
G.SHDSL due to the low complexity of the algorithms and the low latency required for voice traffic. The use of TC-PAM provides an additional 'coding gain' that improves the performance of the digital signal in the presence of interference. Compared to SDSL (2B1Q, or CAP), TC-PAM is more spectrally friendly, ensuring compatibility with other DSL-based services such as ADSL.
14.3 CONTROL CIRCUIT
The control circuit is based on a micro-controller and determines the operational status of the unit according to the state of the transmission system, the data interface and the configuration information received from the terminal.

Check that one AM200 is set to CO and the other(s) to CPE.
4.
Ensure the modem is being used on unconditioned twisted pairs.
Check the correct pin connections are being used on the RJ45 line connector.
Check that the transmission distance is not beyond the range of the equipment.
5.
If using an adapter to connect to a BT EPS8/9 line, check that the colour is grey for the AM200.
Where can I get a Terminal Emulator program?
Most versions of Windows running on a PC come with a VT100 terminal emulator, such as HyperTerminal.
TeraTerm is the recommended VT100 terminal emulator. This can be downloaded from the ATL web site at http://www.atltelecom.com/support
When I plug in the Terminal Emulator I get strange characters on the screen.
The bit rate of the serial port is probably set to the wrong speed. The default bit rate for the AM200 management serial port is 19200 baud. Go to the terminal emulator serial port configuration menu and set the serial port to 19200 baud, 8 bits, no parity, Xon/Xoff flow control.
When using the management terminal, the function keys do not work.
Most PC based terminal emulators allow the programming of the function keys. If you follow the installation of TeraTerm the function keys will be set up for you.
