The BCM 50 Version 1 main unit (I think) has default lines of..
V.O.I.P. from Line 001 to 024 Line pool Bloc A
Analogue COT Line 061 to 064 Line Pool A
BRI ISDN 2 Line 065 to 072 Line Pool B
PRI ISDN from Line 095 to 124 Line Pool Bloc B
Target lines from 125 to 268.
Two other expansion units can be added on and it depends on what Line modules are used, because the line numbers would vary.
I'm not certain on the BCM 400, but I seem to think that this also depends on where the Line modules are placed.
BCM400:
VoIP: Line 001-060
Bus 7: 061-090 (depending on type, US PRI is 23 channels so it would be 61-83. For a GATM-4 it would be 061-064)
Bus 6: 091-120 (same as remarks as Bus 7)
Bus 5: 121-150 (same as remarks as Bus 7)
Bus 4: 151-180 (same as remarks as Bus 7)
Bus 3: 181-210 (same as remarks as Bus 7)
Bus 2: 211-240 (same as remarks as Bus 7)
Target Lines are 241-492 (I believe thats the ending)
