No. You are confusing routers with switches.
A switched circuit is a switched circuit. If you have a 64Kbps circuit, then
this means that you can move 64Kbps through that circuit. Period.

Call routing time and packet switching time are unrelated in switching

Same way anyone does when they replace PABX equipment.
I have heard conflicting reports on this. Somewhere I had gained the
impression that UTS's external phone connection was already optical, but
someone else suggested that they've only just made the change.
Additionally, Optus doesn't do ISDN. Assuming that the PABX is (and has been
for a while) entirely digital, and further assuming that an intelligent TA
has been handling the ISDN connection, then the only change in switching to
Optus would be the disconnection of Telstra's NTU (ISDN box) and the TA
(roughly, ISDN equivalent of a modem) and the connection of Optus's link
(which is a straightforward serial port).
(Hmm. Problem. If Optus doesn't do ISDN still, then I don't follow how the B
channels are seperated out. The above may be wrong.)

Not on the service, on the customer equipment at UTS's end. But possibly
this isn't the case.
