Libpri version is 1.4.11.1.  Sorry.

The message I get is

WARNING[3502]: chan_dahdi.c:4160 pri_find_dchan: No D-channels available!  
Using Primary channel 16 as D-channel anyway!

which is the same message I get if I attempt to start up Asterisk with the 
ISDN disconnected.  (I transferred the cable from one machine to the other, 
so that eliminates that as a cause.  Could the card be the problem?)

With the ISDN disconnected, I get:

Primary D-channel: 16
Status: Provisioned, Down, Active
Switchtype: EuroISDN
Type: CPE
Overlap Dial: 0
Logical Channel Mapping: 0
Timer and counter settings:
  N200: 3
  N202: 3
  K: 7
  T200: 1000
  T202: 10000
  T203: 10000
  T303: 4000
  T305: 30000
  T308: 4000
  T309: 6000
  T313: 4000
  T-HOLD: 4000
  T-RETRIEVE: 4000
  T-RESPONSE: 4000
Overlap Recv: No

On the working box  (connected to ISDN and calls going in and out; running 
older versions of all software),  the same command produces:

Primary D-channel: 16
Status: Provisioned, Up, Active
Switchtype: EuroISDN
Type: CPE
Window Length: 0/7
Sentrej: 0
SolicitFbit: 0
Retrans: 0
Busy: 0
Overlap Dial: 0
T200 Timer: 1000
T203 Timer: 10000
T305 Timer: 30000
T308 Timer: 4000
T313 Timer: 4000
N200 Counter: 3
