FCAS tables

[coniglio]

how important are FCAS tables? what do they do exactly? one of my remote sites has about a million RLIs and each area code points to a different RLI. I'd like to condense them but each RLI has an FCAS table. How specifically does FCAS work? don't have a BARS NTP. thanks

BARS is found in the Networking documentation of the NTPs.

Be very sure of your changes made in NARS/BARS as you can elliminate your users ability to access the network.

I wound up eliminating all the FCAS tables. Each rout had an FCAS table blocking 976. I just denied 976 in each individual area code. Same thing, right? Actually, is one option better than the other? is it better to have a whole bunch of identical FCAS tables blocking 976 or is it better to just deny 976 in ld 90? and what would've been the purpose of building an FCAS table for each RLI? Can't you assign an FCAS table to more than one RLI? I know there's a certain amount of RLIs you can assign a particular FCAS table to, but my predecessor made an identical FCAS for each rout. I appreciate your advice.

The purpose of the FCAS tables is to allow/deny specific NXXs per NPA, for individual route list entries. This way, some users can dial an NXX, but not other users. To deny in LD 90, is to deny for all users, at all times. It sounds like in your case, you only need the 976 block in LD 90, and not multiple FCAS tables. You can only have 15 NPAs per FCAS table, so there is a bit of limitation there.
