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.

Table 1: Bundle Types and Supported Interfaces

Bundle Type	Generally Used For	Interface Types Supported
CTP (circuit-to-packet)	Connecting legacy serial interfaces to the IP network	CTP150 Serial interface Multiservices interface T1/E1 interface CTP2000 Multiservices interface Serial interface Serial interface with T1/E1 daughter card (Not supported from CTPOS 9.1R3 Release) Serial interface with 4WTO daughter card Serial interface with IRIG-B daughter card T1/E1 interface
SAToP (structure-agnostic TDM over IP)	Connecting single T1 or E1 interfaces to an IP network	CTP150 T1/E1 interface CTP2000 Serial interface with T1/E1 daughter card (Not supported from CTPOS 9.1R3 Release) T1/E1 interface
CESoPSN (circuit emulation services over a packet-switched network)	Grouping multiple DS0s to one IP circuit	CTP2000 T1/E1 interface—digital voice or data FXS interface (starting from CTPOS release 7.0) FXO interface (starting from CTPOS release 7.0) 4W-E&M interface (starting from CTPOS release 7.0) CTP150 T1/E1 interface—digital voice or data Serial interface—Nx64Kbps (starting from CTPOS release 6.6) 4WTO analog audio interface—1 or 2 audio channels (starting from CTPOS release 7.3R7)
