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 Reason: 1) Unsupported T1E1/IRIG/4WTO Dcard" 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)
