Hi,

Since you are using IISP between the DEC and the Cisco, you will not see 
the DEC in the 1010's various 'show atm pnni ...' diplays, although you
should see the IISP route as a static route in 'show atm pnni pref' e.g.

hper-atm1#sh atm pnni pref

Codes: P - installing Protocol (S - Static, P - PNNI, R - Routing
control),
       T - Type (I - Internal prefix, E - Exterior prefix, SE -
                 Summary Exterior prefix, SI - Summary Internal prefix)

P   T  Node/Port         St  Prefix
- ---  ----------------  -- 
---------------------------------------------------
S   E  1   ATM0/1/2      UP  39.0000.0000.0000.0000.0000.01/96
S   E  1   ATM0/1/2      UP  39.0000.0000.0000.0000.0000.02/96
S   E  1   ATM0/1/2      UP  39.0000.0000.0000.0000.0000.03/96


There are some things to check though. Did you specify one side as
network and the 
other side as user?  And, are both sides running the same UNI version
(3.0 or 3.1?)
On the cisco, to set the interface as side 'user' and uni 3.1, do:

   config term
   int atmX/Y/Z
   shut
   no atm auto
   no atm address-registration
   no atm ilmi-enable
   atm iisp side user version 3.1
   no shut
   end

Also, you may need to set the maxvci and maxvpi bits on both sides to a
common
value.  And, if there is a way to turn off DEC's proprietary flow
control, you
should probably do that on that interface :-)  

You already said that you added static routes on both sides.  If the DEC
is connected
to a cloud of 1010's that are all running PNNI, then you can
redistribute the static
IISP route to the DEC to the other 1010's by adding 'redistribute
atm-static' to the
atm router section of your config:

atm router pnni
 statistics call
 node 1 level 56 lowest
  redistribute atm-static

Good luck!
