When there are multiple cells and CA configured, without those parameters enb fails to start with e.g.

n1_pucch_an_cs_count must be > 0 for the CA Primary cell

Set them on all cell like illustrated in enb-2cc.cfg and enb-3cc.cfg Amarisoft examples.

Not sure selected values are best - I took them from above mentioned examples as is.

Reference to documentation about those parameters:
