Hi,

I tested rev. 458 and was able to switch the PLL  mode from E1-locked
to standalone.

Unfortunately I see the same behavior  (even with restarting the
BS-11) as in E1-locked ('hfcmulti' and 'hfcmulti port=0x200) - a
network scan shows either your BS-11 or the other networks and only
sometimes you see all networks

This time I found the local net after 5-10 minutes with a Nokia 9300i
and E70. My 6110 could only see the other networks.

Voice works fine in this revision, there is only some delay. But I
observed some strange behaviour using call hold - when you activate it
on a phone the other party can still hear you. :)



Regards,
Christian
