Okay. I'll take that as my action item. On to the understanding...
I don't understand how someone can aribrarily choose which tandem an LRN hangs off of. Why aren't they forced to keep an LRN attached to whatever tandem handles a given incumbent rate center? In my situation, 815-901 is in DeKalb. DeKalb's tandem is... DeKalb. How can Comcast decide to throw it onto Dixon's tandem? I wouldn't have this confusion if Comcast's LRN in Dixon was from an NPA-NXX assigned to Dixon. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Matthew Crocker" <[email protected]> To: "Mike Hammett" <[email protected]> Cc: [email protected] Sent: Tuesday, August 28, 2018 8:53:27 PM Subject: Re: [VoiceOps] LNP, tandems, etc. Mike You either need to connect to the other tandem or pay another carrier to get you there. It is the responsibility of the originating carrier to get the call to the terminating carriers switch. Depending on the call volume you should probably just route through your LD carrier On Aug 28, 2018, at 9:15 PM, Mike Hammett < [email protected] > wrote: I drew a picture, hoping it would clear things up a bit. Through my switch, we're trying to call a number in a block assigned to Sycamore, with an LRN in a DeKalb number block, but the common tandem operator is telling me that the LRN actually lives on a different tandem. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Mike Hammett" < [email protected] > To: [email protected] Sent: Tuesday, August 28, 2018 4:46:52 PM Subject: [VoiceOps] LNP, tandems, etc. I thought you had to be on the same tandem to port a number, but with what our tandem operator (Frontier) is telling me, this isn't the case. Comcast ported a number from us in town A. The LRN they pointed to is based in town B (per TelcoData). The tandem generally used by carriers in both towns is based in town B. Naturally, we send traffic to that tandem. The operator of that tandem is telling us that the LRN is actually homed off of a different tandem in our LATA (operated by CenturyLink) in town C. Unfortunately, I can't corroborate this information with TelcoData the only rate center I see off of that tandem in TelcoData is an AT&T town next door. Where can I read up authoritatively on the porting requirements that would apply to this and related bits of info I should know? I'm checking on our LERG access as I know that has the authoritative information, but I don't have that access at the moment. Maybe we're not subscribed to it.
