Thanks for the reply, Bruce.  The Westell modem is described as an "ADSL 
router" in
its online docs.  There is  a table for VC (virtual connection) 
configuration,  and it shows
VPI 0 (zero) / VCI 35 enabled with protocol set  to PPPoE.  

I tinkered with VCI 35, and changing it to "Bridge."  Then nothing 
worked.  But after  "enabling"
VCI 36 to "Bridge," and leaving VCI 35 at PPPoE,     voila !!!    

Thanks for steering me the right way, Bruce.

Happy New Year,
Dan Martin
