A CESoPSN bundle represents an IP circuit emulation flow. With CESoPSN bundles, you can group multiple DS0s on one IP circuit, and you can have more than one circuit emulation IP flow created from a single physical interface. For example, some DS0 channels from a T1 interface can go in an IP flow to destination A, and other DS0 channels from that same T1 interface can go to destination B. This feature allows for payload optimization.

CESoPSN bundles comply with RFC 5086, Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation Service over Packet Switched Network (CESoPSN), December 2007. RFC-5086 defines a standard for transporting multiple bundles of DS0s from a single physical interface to different network destinations.

CESoPSN bundles are supported on the following interface types:

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)

And, they are all interoperable, if the number of channels and the signaling configuration (on or off) are consistent at each end of the bundle.

CESoPSN bundles support the following signaling:

T1 interfaces support channel-associated signaling (CAS).
E1 interfaces support CAS and common channel signaling (CCS).

Starting from CTPOS Release 7.0, CTP2000 devices support analog CESoPSN bundles over T1/E1, even if a VComp module is not installed. To create an analog CESoPSN bundle, the T1E1 interface module must be installed in slot 0. If the T1E1 interface module is not installed in slot 0, the system displays the following message:

content_copy zoom_out_map
Analog  CESoPSN Bundle will be created only when there is a T1E1 card present in slot 0.

Note:

You cannot create an analog CESoPSN bundle and a VComp bundle on the same card.

You can interconnect the following voice applications with CESoPSN bundles:

Analog 4WE&M voice applications using the 4WE&M interface module
Digital voice applications using the T1/E1 interface module
