The Ericsson AXE and Alcatel E10(OCB) exchanges used here seem to have identical services. There is a difference in how they respond to requests however:
AXE will usually give an announcement to tell you the service is setup and confirmed.
E10 will more often give you a ring tone to confirm setup and a busy tone or reorder tone if it can't set it up.
If you've used a completely invalid code, it will give you the "tri-tone / SIT"
It all depends on how old the E10 or AXE exchange (or RCU) is, some have been retrofitted with automatic announcement units, others arn't and still have fairly simple looping analogue announcement machines in place so can only do fairly basic announcements.
You'll either get a very sophisitcated digitally recorded announcement or
a rather less sophisticated repeating announcement which plays off a looping announcement machine.
Oddly enough though, they can all do sophisitcated announcements for last number (1471), number changes, etc etc. It's just for generic announcements that they'll revert to loops.
