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 TypeGenerally 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
    • 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)

Grouping multiple DS0s to one IP circuit

  • CTP2000
    • T1/E1 interface with unused DS0s
    • FXS interface
    • FXO interface
    • 4W-E&M interface
  • CTP150
    • T1/E1 interface with unused DS0s
    • Serial interface

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)

Grouping multiple analog circuits (channels) into one IP circuit

  • CTP2000
    • T1/E1 interface
    • 4W-E&M interface
    • Voice compression module
    • FXS interface
    • FXO interface
