DASS is a pre-standard ISDN signalling used by BT in the UK that's no
longer available for new supply, you can quote for BT (or reseller) to
convert the ISDN line to a standard ISDN30 though they will charge for
this but you'll have to do this before you can terminate it on a Cisco
gateway.
The timeslot configuration is another issue but there shouldn't be any
difficulty handling this once you have a standard euro ISDN30.
