C.12 V.11 ports
The V.11 ports are tested on correct settings and bit errors using data test equipment.
1. Check the port settings in the configuration (Configuration / Data port to modem
assignment) and use the same settings in the test equipment.
2. Connect data testers to corresponding ports on both the local and remote ETL600
equipment. If there is only one data tester available, the digital data stream has to be
looped on the remote equipment.
3. Perform a BER test (recommended number of bits to transmit: ≥ 10
C.12.1 V.11 Port 1
If used, perform a BER test as described above.
C.12.2 V.11 Port 2
If used, perform a BER test as described above.
C.13 V.24 ports
The V.24 ports are tested on correct settings and bit errors using data test equipment.
1. Check the port settings in the configuration (Configuration / Data port to modem
assignment) and use the same settings in the test equipment.
2. Connect data testers to corresponding ports on both the local and remote ETL600
equipment. If there is only one data tester available, the digital data stream has to be
looped on the remote equipment.

C.13.2 V.24 Port 2
If used, perform a BER test as described above.
C.13.3 V.24 Port 3
If used, perform a BER test as described above.
C.13.4 V.24 Port 4
If used, perform a BER test as described above.
C.13.5 V.24 Port 5
If used, perform a BER test as described above.
C.13.6 V.24 Port 6
