I know of at least one major bank that drops the following
to their ATMs:
- Frame/ATM Frac T1
- ISDN BRI dial backup
- 9600 baud X.25 analog dial backup backup
If all that fails on a wide scale, you have much larger
issues to contend with.
Note that there are still a few vendors of ATM switching
hardware:
Lucent/Ascend
Nortel/Bay
Cisco/Stratacom
Alcatel
Marconi/FORE
Hitachi
NEC
Fujitsu
...
And this doesn't include all that legacy hardware out there
already. *cough cough* Newbridge *cough cough*.
