Types of Bundles Overview

 

Table 1 shows the typical application for each bundle type, and lists the interfaces that each type of bundle supports.

Note

Starting in CTPOS Release 9.1R3, the T1/E1 Daughter card is not supported in CTP150, CTP151, and CTP2000. If the Daughter card is present in these devices, then you will get an error message "System is unusable" when you use CTP nodes. Remove the Daughter card to access the node.
