Protocol: Choose your local ISDN protocol.
Set the “LEASED LINE” value to perform tests without signalling
protocol over the D channel., i.e. Unframed BER. Use the
“OTHER” parameter to capture signalling protocols not directly
supported by the instrument in Monitor mode (see Chapter 7).

“OTHER” parameter to capture signalling protocols not directly
supported by the instrument in Monitor mode (see Chapter 7).
Protocol type: Select the protocol operating mode between Master and Slave. After
you have selected the operating mode of the instrument (i.e. TE or NT) the “Protocol
type” field is automatically set with the typical value for normal operation.

Ω termination: Choose if you want to add a 100 Ω termination. You can
use this option if the line at this point is not terminated correctly. The default value is

Vmin threshold: Set the minimum voltage value under which the instrument resets
its line interface. Use the 28 V (ETR080) default value when no other value is
preferred. NT1-U only.
