Table 50 compares the designated extension numbers on the Norstar and on the BCM systems.
Setting DNs and port numbers
The MBM, based on the switch settings, defines which DNs and port numbers can be populated
with telephones. If you have changed the default start DN for your system, use Table 51 to identify
the DNs and ports for your sets. If you are using the default start DN (221), a completed chart is
provided in Table 61 on page 163.
