Network Change:This is the fifth revision to the long term network change notice ATT20151028L.1 for this project, which is also associated to NCNs ATT20150911S.3,ATT20150911S.3 rev1and ATT20151029L.1 rev1. The reason for this revision is the due date is not obtainable due to network freezes and AT&T is extending the window of implementation to 3rd quarter to meet these ASR obligations for carrier rehoming. AT&T Texas has developed a project with the plan to eliminate the Nortel DMS STPs in Abilene, Texas. This will require re-homing all the SS7 linksets from the Abilene Nortel DMS STPs (ABLNTXOR04W/ABLNTXOW04W)intothe Austin, Texas (AUSTTXGR57W/AUSTTXTE13W) Tekelec STPs. This change will consolidate STPs in LATA (550) to LATA (558).
Description of Type of Changes Planned:
AT&T Southwest will be decommissioning the STPs in the AT&T Abilene, TX area. Carriers who connect with AT&T Southwest in the Abilene LATA (550) need to migrate their SS7 linksets. The NEW FSPOI codes are ABLNTXOR34W/ABLNTXOW19W. AT&T will transport the SS7 links from the FSPOI to the new STP location in LATA 558.
Abilene - LATA-550
ABLNTXOR04W/ABLNTXOW04W
Point Code - 249-050-000/249-051-000 - Alias 249-083-000
Austin-LATA-558
AUSTTXGR57W/AUSTTXTE13W
Point Code - 249-012-000/249-013-000 - Alias 249-151-251
Description of Reasonably Foreseeable Impact of the Planned Changes:
Carriers will need to move their SS7 links and must coordinate the activity with AT&T. AT&T will communicate more details with affected Carriers in 3rd Quarter, 2017. It is anticipated that Carriers will have to issue ASRs to connect to the FSPOI in the existing LATA (550) and that Carriers will not have to transport their SS7 links any further than they presently do. ASRs will need to be issued prior to the cutovers with the existing FSPOI, and the new Far End CLLI and Point Code. The Carriers will need a technician in their Central Office or STP during the maintenance window on the night of the cutover to make changes in the SS7 routing tables with the new set of point codes shown above.
