	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*.
