PSTN cut-overs - PRI, BRI, 1FB analog, etc.
This might seem broad, but I'm interested in the cut-over of a customer's PSTN service. Specifically:
A customer currently has ISDN BRI and analog trunks coming in for PSTN access. We're going to be proposing an IP telephony Cisco solution for them, and they'll be converting over to a full PRI in replacement through a Cisco ISR gateway. My question concerns the whole process of arranging the switchover in the circuits, specifically:
1) what does the actually "turn up" up the circuit look like, configuration-wise? If the PRI is scheduled for a certain time, is it generally predictable (down to the hour), where you and the customer can expect a clean switchover at a specific time?
2) what about the incoming phone numbers/DIDs? Can you generally arrange that all numbers that were coming over the analog (or BRI) circuits will also be cleanly cut-over at a predictable cut-over window?
Hopefully this is enough to explain my gaps in experience - the goal is simple: schedule a cut-over from their existing circuit(s) to a new PRI through an IPT voice gateway, and I want to make sure it's a clean cut.
Thanks in advance - the more detail, the better...

I could tell you my experience of this, but that's only relevant to the Telco I was with at the time. Every provider has different procedures, and these change over time.
The best thing to do would be to sit down with the customers account manager and go over the cut-over process they have in place, then see where there are any gaps in the service delivery and try and fill those gaps. You'll probably need to push them a little depending on the level of service/how large the customer is.
