/* module parameters:
* type:
Value 1 = BRI
Value 2 = PRI
Value 3 = BRI (multi channel frame, not supported yet)
Value 4 = PRI (multi channel frame, not supported yet)
A multi channel frame reduces overhead to a single frame for all
b-channels, but increases delay.
(NOTE: Multi channel frames are not implemented yet.)
* codec:
Value 0 = transparent (default)
Value 1 = transfer ALAW
Value 2 = transfer ULAW
Value 3 = transfer generic 4 bit compression.
* ulaw:
0 = we use a-Law (default)
1 = we use u-Law
* limit:
limitation of B-channels to control bandwidth (1...126)
BRI: 1 or 2
PRI: 1-30, 31-126 (126, because dchannel ist not counted here)
Also limited ressources are used for stack, resulting in less channels.
