Hello Harald,

Dieter, what I just found out is that the LI object has a user-configurable
setting, where we can force it to be stand alone or locked to the E1.
We could add this setting to the bs11_config program so people can try
if their E1 clock or their [10 years uncalibrated] BS11 internal oscillator
is better.
What do you think?
I did a quick test with this setting and it seems to work fine
with the BS-11 (so we should not believe the documentation ;-).
Here is the LMT dump for the PLL Mode, it can be changed during
normal operation:
; Locked
Tx D0A5070000FC0102
Rx D1A5070000FC0102
; Standalone
Tx D0A5070000FC0103
Rx D1A5070000FC0103
A little bit strange is the behaviour of NM_ATT_BS11_CCLK_ACCURACY,
if the PLL Mode is set to "Standalone", it changes to "high
accuracy",
however if you restart the BS-11, this attribute stays at "medium
accuracy". Maybe NM_ATT_BS11_CCLK_ACCURACY has no meaning if the
PLL Mode is set to "Standalone".
Best regards,
Dieter

I've tested (+fixed) it now. 'query' now also shows the current PLL Mode
configuration (as of SVN rev. 455)

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
