Order of Installing Trunk Blades
2.2.3.1 Installing CD-4COTA, CD-4DIOPB, CD-4ODTB or
blades
The order in which trunk blades are physically inserted
determines the numbering plan.
For example, if four blades are installed in the following order,
the numbering plan below applies.

2.2.3.2 Installing CD-PRTA (T1/PRI/E1) Blades
The CD-PRTA (T1/PRI/E1) Interface blade uses the first block
of 30 consecutive trunks.
For example, if the CD-4COTA and PZ-4COTE blade is installed
for trunks 1~8, the CD-PRTA (T1/PRI/E1) blade automatically
uses trunks 9~38. If CD-4COTA and PZ-4COTE blades are
installed for trunks 1~8 and 17~24, the CD-PRTA (T1/PRI/E1)
blade uses trunks 25~54. The CD-PRTA (T1/PRI/E1) blade
cannot use trunks 9~16 (even if available) since they are not
part of a consecutive block of 30 trunks.
To avoid unexpected extension/trunk numbering
if the VoIP or Voice Mail daughter board
registers with the system first, install these
boards after the other types of extension and
trunk blades are installed.
