BARS 3

[nickwj]

Hi, we have 65 sites each with its Meridian PBX.

When a user dials 9 I think the switch uses BARS (AC1), to deterime which route to take (111 for local calls, 108 for national) and the NCOS of the users handset against the FRL table of the route ( is the user allowed to make external calls etc?).

I think the the switch checks the areas code to determine if the call is local or national.

I think these codes are stored in a NPA table.

How do I print these tables to look at the area codes?

I can see we SPN for specialised numbers i.e. Directory Enquiries.

If we do not use NPA or BARS what else would we use if a user dialed '9'.

I am trying to print the tables in overlay 90 but just get an error what ever I type in at the NPA prompt.

NPA ??????????

Any help would be most apreciated.

Cheers Nick.

Don't type anything there, just hit enter, or put in a single code, but with North America national code...1 so, 1614, or 1606, etc. No entry, prints them all

and your thinking is pretty close to right... if ac1 is 9, 9 takes you to ld 90.. the switch looks at the next digits for a match... npa nxx dddd (state side). if i have npa 1213, it points to a rlb... that sends me to ld 86, prt the rlb and that points to a rdb and assigns a frl... if nctl is clear translation.. (frl 0 = frl 0 thru 7=7) and my ncos is 3 on the phone, the frl is 3 or lower.. the switch dumps the digits to the trunk... last chance the switchman has to control those digits is the dgt... you can delete leading digits or add trailing digits to the actual dial string..


if all the trunks in that rdb (ld 21 ltm) are busy, the rlb has a second entry.. and if entry 0 is frl 3, my ncos is 2, it checks all entries to see if i can use any of them...


you've got time of day routing, which is seldom used.. and you enable auth codes on the rlb...

read GH"s post, it will help... best bet is to print and trac untill the call flow becomes clear...

Thanks for all your help guys.

It looks like we do not use NPA, but SPN for special numbers and area codes. Working through the list to see if can make head and tails of it.

Dont know if that it the correct way of doing it, perhaps its the way we do it here in the gloomy UK. I really envy you guys who live in the States.

Cheers Nick.

Hi, sorry to bother you again.

Have checked and we have 96 SPN's listed. All route local PSTN (route 111), but use ARRN and ARLI which will route calls internally (Route 150 which is our internal IP network) if the number dialed happens to be an internal ext of one our sites. I.E. if site A dials site B using 9 and external number, the switch will use ARRN and alternate RLI and DMI to route call over internal network.

Any other area code dialled will use our National route(108), but cannot see that anywhere. I presume that there must be some programing somewhere that states if area code is not one of the SPN numbers listed route national (108).

Is that correct?
Where would the code be?

Once again may thanks for your help.
Nick.

Go to ld 11 or 20 and prt that as dnb and see if it comes back with any info

Check your FCAS tables in LD 87, and, as JP stated, check your DGT tables in LD 86. These will tie together in the RLBs in LD 86, which are referenced by your SPNs, NXXs, and NPAs. These are probably being checked for internal network numbers using these programming combinations. Study it carefully. It can be real daunting.
