Trunk Assignments for Double-Cabinet Systems

•When ISDN is used in a two-cabinet system, the number of ISDN channels that can be assigned in each cabinet depends on the master/slave designation.

•Fractional ISDN per port assignments require the VB-43511A version of the loop start trunk card. The older VB-43511 version may be used with fractional ISDN but requires that the trunks be assigned in blocks of 8.

The following table shows the maximum number of ISDN channels that can be assigned in two-cabinet systems.
