SPN 'FLEN' question 1

[mrgauth]

I am trying to determine the correct length of the FLEN in my SPNs.

I have SPNs set up for our internal 7 digit dialing plan. Our AC2 is 8 and that gets us to our SPNs. For instance, one of sites is SPN 755 and the users dial 8+755+XXXX to get someone at that office. Under that scenario, what should my FLEN be? In the RLI pointed to we re-insert the 8 so that when the call gets to the other site it will look at the SPN's at that site. If passing through that site to others, the SPN's kick in, if ending at the 755 site, then the HLOC del 3 so that only the last 4 digits come into play.

Bottom line, should the FLEN be 4 or 7 or ? or does it really matter?


Thanks.

the flen needs to match the total digits dialed minus the ac .. i would usually set that up a little dif, but sounds like it works.. if i dial 81 (ac) the 455, (spn) + 4 digits (ext) ld 90 see's 7, the dgt inserts or deletes after the routing decision has been made... either ac does nothing more then routes the call to load 90, ld 90 see's the following digits

Then that would be a 7. If I am reinserting an '8' with a DMI in the RLI, does the FLEN still need to be a 7 since I am essentially sending 8 digits across the tie. Or, as you said, is it totally dependent on the actual DIALED digits?

We do this everywhere, but I had little to do with picking FLENs and I have always wondered what exactly we should be set up as.

And thanks for the quick response by the way.

right, the 8 is inserted after the calls is routed to the rlb be the dgt table. the flen if correct makes switching faster, the switch knows that the 7th digit is last, doesn't start the inter-digit timer and then the eod (end of dial)... just keeps your cpu from being quiet so loaded. never a bad thing
