level, a red exclamation mark appears on the port in the upper Hardware –
menu and a red text is displayed in the upper stack status field. This Boards
error status gets changed after the SLIP rate falls below the level. The lower
interval between these two values represents hysteresis.
Settings for BER – select to enable acceptable interface error BER as error
parameters. If the BER rate gets over the level, a red exclamation mark upper
appears on the port in the menu and a red text is displayed Hardware – Boards
in the upper stack status field. This error status gets changed after the BER value
falls below the
level. The interval between these two values represents lower
hysteresis. The BER values are entered in an exponential format (e.g. 3e–5
means 3 errors in 100,000 bits). In practice, the BER may occur on a virtual port
close after the cable connection. In that case, this is not an error if the BER
disappears in a few minutes.

Specific interface parameters
Multiframe – is the first layer parameter of the So bus. For details refer to
recommendation I.430.
Extended bus – use this parameter to activate an extended bus. With just one
terminal and proper terminating impedance you can extend the PBX–terminal
distance up to 1,000 metres. This parameter can be set for an NT port only.
Priority 10 – is the first layer parameter of the So bus. This parameter can be
set for a TE port only.
