Checklist of the essential ingredients to a successful cutover
- Typical IPT conversion example
•Request Customer Service Record from LEC
•Determine existing SDN service
•Order local & LD PRI’s – turn circuits up with test numbers
•Order SDN switched access for new Local PRI Billed Telephone
Number (BTN)
•Order Disconnect of SDN ranges from dedicated access
•Schedule separate cutovers for port of both DID ranges (local)
(Shirley will coordinate where AT&T is LEC) and SDN ranges (LD)
(Sharon will coordinate)
•If no new SDN dedicated access, issue VON order at time of cutover
once SDN ranges are removed from the old circuit
•After successful cut, issue disconnect orders for old local and LD
circuits
