RESETETH Port
This command resets the Ethernet statistics for a particular port. On the Watson
Ethernet tabletop modem it is not required to specify a Port number.
7.4.3 Bit error rate tests
Bit error rate testing functions are available on the tabletop modems only.
STARTBER m dir p
The STARTBER m dir p command starts the pseudo random binary sequence
(PRBS) generator and bit error rate (BER) meter for a duration of m minutes.
The test signal generator sends a PRBS of length 2
15
-1 according to ITU-T
O.151 (p = 0) or a PRBS of length 2
11
-1 according to ITU-T O.152 (p = 1).
If dir is 0 then the PRBS is sent towards the remote modem and an external
hardware loop must be established at the user interface of the remote modem
(loopback connector).
Selecting dir = 3 will start an internal DSL bit error rate test which is indepen-
dent of the user interface. A loopback with LOOP2 on the remote modem must be
