I have been through several settings
Some say leave 1st (MBM)4x16 all on(don't know if first is top or bottom...I think Nortel counted from the left in the MICS)I chose bottom. Top 4x16 I have tried 3, 4, 5, 6. I look in resources and have 4 modules in 2. I tried the reverse too.
Have eleven extesion up. Started out with one set and I can see 8 ingoing lines that I have plugged in.
Some of twenty sets show up 254 to 264. The rest seem to be live but no extension on F*0 intercom. Other just flash forever.
Bus 01, 3,4,5,6,7 are Stn Modules Bus 2 is only trunk module Bus 8 is data module
