approximates the cable length from the DSX-1 port to the PBX.
23. DSX-1 CFA.
Repeatedly

Ye s causes the Centum Series unit to pass “red alarm” signals to the
PBX for appropriate action.
Refer to NI CFA, item #9, earlier.
If NI CFA is Ye s , choose DSX-1 CFA No.
If NI CFA is No and the network is provided by a common carrier,
such as a telephone company, choose DSX-1 CFA Yes. Ensure that
the attached PBX will react to a three-second “red alarm” by
discarding data and sending a “yellow alarm”.
If NI CFA is No and the network is private, the selection is a user
option.
