Types of Bundles Overview

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

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 T1/E1 interface CTP2000 Serial interface Serial interface with T1/E1 daughter card 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 T1/E1 interface
CESoPSN (circuit emulation services over a packet-switched network)	Group multiple DS0s to one IP circuit	CTP2000 T1/E1 interface with unused DS0s An unused DS0 is a DS0 not assigned to another bundle. When a CESoPSN bundle is attached to a port, by default all unused DS0s are assigned to the bundle.
VCOMP (voice compression)	Group multiple analog circuits (channels) into one IP circuit.	CTP2000 T1/E1 interface 4W-E&M interface Voice compression module
