pdoisy: From the type number of my set, I think it is only one-way.
I hope to be wrong again! ;-)
If you can confirm...
Unfortunately, I can't confirm the 2611, but I have a 2616 - and it's a two way model. For absolutely sure, because I use it with a BL7000 :)
So, if I know well, my BC is a later model, so I think, Your 2611 used to be a two way model.
Anyway - why do You think, that Yours is one way only?
