I would assume that you could just provide an accurate E1 clock to the BS-11,
then read the 'work value' and set the 'set value' to the value you have
obtained.
At least that would be my solution if I was designing a BTS and had to
implement a solution for the calibration...
Might be worth some experimentation.
Regards.
