where:
N = number of defined FCAS tables
M = average number of NPA codes per table
P = average number of the first digits in NXX codes

ranges regardless of which office codes they belong to). A maximum
of 20 ranges of office codes can be defined per locations code. (That
is, one office code and 20 ranges, or 20 office codes and one range

Note 8
The protected data store requirements for CDP (on a per customer basis) are:
BASIC_ESN + SC x 3 + RL x (8 + 3 x RLE) + DME x (3 + I/4)
where:
BASIC_ESN = Size(ESN_DATA_BLOCK)
+ Size(NCTL_DATA_BLOCK)
Size(NCTL_DATA_BLOCK) = 306
SC
RL
Memory, Storage and CPU capacity
= number of on-net or virtual locations
= (N + 1) + N(M + 1) + MN[4 + (100P + 15)/16]
= number of supplemental digit restricted/recognized blocks
defined for npa, nxx, loc, spn
Exclusion Index
= (2 x number of total office codes) + (2 x number of total DID
