When your service area is taken care of by one tandem in the LATA, do you connect to the other tandems in your LATA? Currently I just send anything that's not on my single tandem (or my direct connections) to my interLATA termination. How common is that? It's pricey to build out to the other tandem. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com
It depends on who the ILEC is and whether you're interconnected via your own SS7 trunks or not. In BellSouth territory you can order a multi-tandem super group to cover all the tandems in the LATA. You just pay a per-MOU charge to have them deliver the traffic to the other tandems. Its not worth it if you have to send a lot of traffic though. In the Verizon and other AT&T areas they make you order trunks to every tandem so you don't have a choice. In the old CenturyLink areas you could send traffic through your Access Tandem group as long as you had SPOP in your ICA. Your other option is to "lease your PSTN connection" through a third party provider like Inteliquent, Peerless, or Wide Voice that have SS7 trunks connected to every tandem in that LATA. It eliminates your need for SS7 links but you do pay a per MOU for every call.

*nods* In my area, different companies operate the two tandems, so then I need a third party to get there. That makes it fun. :-) ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Mary Lou Carey" <marylou at backuptelecom.com> To: "Mike Hammett" <voiceops at ics-il.net> Cc: "VoiceOps" <voiceops at voiceops.org> Sent: Tuesday, June 15, 2021 11:04:28 AM Subject: Re: [VoiceOps] Multiple Tandems Per LATA It depends on who the ILEC is and whether you're interconnected via your own SS7 trunks or not.

That makes it almost impossible because very few companies offer SS7 transport anymore. MARY LOU CAREY BackUP Telecom Consulting Office: 615-791-9969 Cell: 615-796-1111 On 2021-06-15 03:47 PM, Mike Hammett wrote:
