2 INTRODUCTION
The AM200 is a DSL modem that complies with the G.SHDSL standard for high-speed digital line technology.
It is capable of transmitting up to 7½ Km at 128kbps over 0.5mm2 cable (5.9Km at 2Mbps).
The AM200 supports transmission rates from 128kbps to 2.3Mbps over a single pair copper line.
The AM200 provides a combination of Ethernet, X21/V35 and G703 interface options. All of the interfaces
can be operated simultaneously. The X21 and V35 Interface options require the use of a special converter
cable that attaches to the 25 way D-type connector on the back of the AM200.
The Ethernet interface supports Routing and Bridging over PPP and Frame Relay. The Nx64 interface supports
data rates between 64kbps and 2.3Mbps. The Nx64 supports V35, X21 and RS530 user selectable interfaces.
Management control can be provided remotely via SNMP, Telnet, and Web Browser or locally via the RS232
connector. Alternatively the AM200 (LCD version) can be set-up locally using the menu/navigation buttons on
the front of the unit.

5 INSTALLATION
This chapter describes the basic steps that are required to set up a system using the AM200 DSL modem.
It is recommended that if two desktop units are to be connected they should be tested back to back to check
for operation before deployment.
5.1 CONNECTION OF PROTECTIVE EARTH
If a G703 port needs to be connected to a circuit that is defined as TNV, then a protective earth must be
connected to the earth bond stud on the rear panel. See the Safety Statements at the front of this User
Guide.
5.2 LED POWER ON SEQUENCE
The TEST LED is red during the boot sequence and self-test.
Followed by all LEDs flashing orange for 45 seconds.
Followed by normal operation.
5.3 LCD POWER ON SEQUENCE
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 userport 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.

6 QUICK START GUIDE
This section of the manual is intended to allow the user to set up the AM200 in a simple point-to-point
configuration quickly, and simply.
Figure 11 Point-to-Point Configurations
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.

6.3 ETHERNET
6.3.1 CONFIGURATION AS A BRIDGE
The User's PC and the Network are connected directly together and so must be on the same IP subnet.
Figure 12 AM200 to PC Connection
Figure 12 shows a PC connected to a local LAN. If the user wishes to connect a remote PC to the LAN then
a pair of AM200s may be used to bridge between them as shown in Figure 13.
Figure 13 AM200 Bridge
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.
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

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
--> 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.

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.
Please refer to the diagrams on the following pages.

7.1.1 Internal Timing
7.1.1.1 G.703 to G.703 Internal Timing Master
Slave terminals are connected to the digital section at both ends. The clock source inside the CO then
becomes the reference clock for the entire system.
The internal clock is generated at the CO. Both terminals lock to this clock and return the clock to the
AM200s. An elastic store in the AM200 buffers the data.
1. At the CO, select the 'Local' timing option for the G.703 port.
2. At the CPE, select the 'Local' timing option for the G.703 port.
This is the default timing mode for G.703.
7.1.1.2 G.703 to X.21/V.35 Internal Timing
Slave terminals are connected to the digital section at both ends. A clock inside the CO then becomes the
reference clock for the entire system.
The internal clock is generated at the CO. Both terminals lock to this clock and return the clock to the
AM200s. An elastic store in the AM200 buffers the data.
1. At the CO, select the 'Local' timing option for the G.703 port.
2. At the CPE, select the 'DCE' mode option for the Nx64 port.

7.1.1.3 X.21/V.35 DCE to X.21/V.35 DCE
The terminals connected to the digital section at both ends are DTEs. A clock inside the CO then becomes the
reference clock for the entire system.
1. At the CO, select the 'DCE' timing option for the Nx64 port.
2. At the CPE, select the 'DCE' mode option for the Nx64 port.
This is the default timing mode for Nx64.
7.1.2 G.703 to G.703 Transparent Timing
In this configuration, the terminals are the source of timing. One of the connected terminals may act as a
master, the other as a slave. However, both terminals could operate independently or plesiochronously.
Clocks T1 and T2 are independent of one another and are transported independently through the DSL system.
1. At the CO, select the 'Through' timing option for the G.703 port.
2. At the CPE, select the 'Through' timing option for the G.703 port.
