•Two-cabinet systems use the same trunk numbering scheme as single- cabinet systems: analog trunks are numbered from “1” upward; ISDN trunk channels are numbered downward from the highest channel used.

Tables 2-6through 2-10show trunk numbering for two-cabinet systems using the maximum number of ISDN channels.
