BASIC DATA ASSIGNMENT
(c) NCN (Network Controlling Node)
STEP 1: ALRTN - Assign the Logical Route Numbers to all external trunks used in the network. Assign unique
Logical Route Numbers to the whole routes for external trunks on the network (including COT, DAT,
dummy route, etc.) using this command. When the network accommodating multiple FCCS Networks
(FUGs) and/or NEAX7400ICS M100IMX is established, the data must be set at the NCN in each FUG
and is to be set for every external route in all the nodes.
STEP 2: ARSCN - Assign route restriction information according to the Route Restriction Class (RSC) of the
Logical Route Number in the network.
STEP 3: ANPDN - Assign the minimum number of digits needed to determine the service (Telephone Number)
which is required to the first digit received (pre-translation).
STEP 4: ASPAN - Assign the special access code. Assign Abbreviated Digit Code (ADC) for connected FUGs
using AEADN command.
STEP 5: AFRSN - Assign the NPC (Number Pattern Code) and OPR (Outgoing Route Selection Number) for
dummy route number.
STEP 6: AOPRN - Assign the routes and in what order these routes will be selected corresponding to the data
assigned by AFRSN command.
STEP 7: ARNPL - Assign the access code for LCR/LCRS as assigned in ASPAN associated with the logical
routes for each external trunk assigned in ARTD/ ARTDN command.
STEP 8: AMND - Assign the number of necessary digits to be received by the Register (ORT/IRT) circuit.
Note 2: The MND is the total number of ACC + Telephone Number.
