8.2.2 REMOTE LOOP
With a BERT still connected as above, turn off the local loop and apply the remote loop. The
remote loop loops data back to the user interface from the far end modem as shown below, thus
this test can be used to check the integrity of the line.
There should be no errors or a very low error rate. If the error rate received is too high for your
application, try a lower data rate. When you have completed this test, turn off remote loop.
8.2.3 FAR END LOCAL LOOP
If the two tests above have been performed then also perform test 8.2.1 (local loop) on the far end
modem.
8.2.4 LOOPBACK
Applying a Loopback on the local modem causes the received line data to be returned to the far
end modem.

8.2 LINK PERFORMANCE
The AM100 modem has a number of features to aid in the testing of the data link. To check a data
link the following tests can be performed. The tests outlined will require the use of a Bit Error Rate
Tester (BERT).

2 INTRODUCTION
The AM100 is a DSL modem that is capable of transmitting up to 4.9 Km at 640kbps over 0.5mm
2
cable (9.8Km at 64kbps).
The AM100 supports transmission rates from 64kbps to 640kbps over a single pair copper line.
The AM100 provides either X.21, V.35 or G.703 interface options. All of the interfaces require the
use of a special converter cable that attaches to the 25 way D-type connector on the back of the
AM100.
The X.21 & V.35 variants can be set to operate in either ‘master’ or ‘slave’ mode. The G.703 is only
available in ‘master’ mode.

3 EXAMPLE APPLICATIONS
The diagrams below illustrate some basic applications.
3.1 DATA LINK WITH NO EXTERNAL TIMING
Figure 1
Either end of the link may be set to ‘master’, with the opposite end set to ‘slave’. The timing
originates from the internal clock of the master and is sent out to the customer’s unit.
3.2 DATA LINK WITH EXTERNAL TIMING
Fugure 2
In this example the master modem accepts timing from the G.703, X.21 or V.35 interface and uses
this to time the link.
