NICA X Reference Manual

Primary Channel
If the NICA X is providing the Primary and Reserve service then the Primary Channel is set here. This must be set
by the user taking into account the primary codec Mode set. It could be set to channel 1, 2, channel 1 or 2 (where
the data service may be on 1 or 2) or channel 1 and 2 (where it uses two channels in an IMUX mode). The
channels could be ISDN or X21 ports depending on the primary codec Mode set.
Primary No.s
If the NICA X is providing the Primary and Reserve service and the Primary service is over ISDN then the
number(s) to dial are entered here for channels 1 and 2.
Reserve Mode
The Reserve Codec Mode is set here. It could be any valid mode from the codec mode list.
Reserve Channel
The Reserve Channel is defined here. This must be set by the user taking into account the Reserve Codec Mode
which has been set. It could be set to channel 1, 2, channel 1 or 2 (where the data service may be on 1 or 2) or
channel 1 and 2 (where it uses two channels in an IMUX mode). The channels could be ISDN or X21 ports
depending on the codec Mode set.
Reserve No.s
If the Reserve Codec Mode is an ISDN Mode then the ISDN numbers for channel 1 and 2 are saved here. There are
two sets of numbers, A and B. If the codec Mode only requires one channel then only one number is entered by
the user in each set. The A number(s) are tried first. If the NICA X fails to connect with these number(s) after the
set number of retries, it will then use the B number(s)
Fail Detect
The Backup operation is continually checking to see if it must activate the Reserve service depending on the state
of the option selected here. The options and their activation criteria are listed below. The Fail detect must be active
for the ‘Drop Time’ setting before the Reserve service is activated.
Fail Detect Method Description
EXTERNAL An External Opto Input, programmed with remote control command CBI,
defines the state of the external Primary service e.g. Active=good,
Inactive=fail (This should also be the selection if you wish to use only manual
intervention via the front panel or CBS command)
