Overview
The SPA-1CHOC3-CE-ATM and SPA-24CHT1-CE-ATM are single-width, single-height, cross-platform Circuit Emulation over Packet (CEoP) SPAs for the Cisco ASR 1000 Series Routers. The SPA-2CHT3-CE-ATM is also a single-width, single-height but supports only the ATM.
CEoP SPAs are available in the following models:
- 2-Port Channelized T3/E3 ATM CEoP SPA (SPA-2CHT3-CE-ATM)
- 24-Port Channelized T1/E1 ATM CEoP SPA (SPA-24CHT1-CE-ATM)
- 1-Port Channelized OC-3 STM1 ATM CEoP SPA (SPA-1CHOC3-CE-ATM)
The following table describes the features supported on different types of circuit emulation (CEM) SPAs.
Circuit Emulation (CEM) SPA Type |

---|---|---|
SPA-1CHOC3-CE-ATM |
3.3.0S |
Supports only the CEM mode. |
SPA-24CHT1-CE-ATM |

SPA-2CHT3-CE-ATM |
3.6.0S |

Either the SPA-1CHOC3-CE-ATM or the SPA-24CHT1-CE-ATM must be installed in ASR-1000-SIP10 or ASR-1000-SIP40 before the SIPs can be used in the Cisco ASR 1000 Series Routers. A maximum of four SPA-1CHOC3-CE-ATM or SPA-24CHT1-CE-ATM can be installed in each SIP; these SPAs can be of different models. You can install a SPA in the SIP either before or after you insert the SIP into the router chassis. This enables you to perform online insertion and removal (OIR) operations either by removing the individual SPAs from the SIP or by removing the entire SIP (and the SPAs it contains) from the chassis.
Pseudowire Emulation over Packet (PWEoP) is one of the key components in the process of migrating customers to a packet-based multiservice network. CEoP, which is a subset of PWEoP, is a technology used to migrate from legacy TDM networks to all-packet networks, and transparently provide transport for legacy applications over a packet network. The SPA-1CHOC3-CE-ATM represents an actual physical connection.
Many service providers and enterprises operate both packet-switched networks and time-division multiplexing (TDM) networks. These service providers and enterprises have moved many of their data services from the TDM network to their packet network for scalability and efficiency. Cisco provides routing and switching solutions that are capable of transporting Layer 2 and Layer 3 protocols, such as Ethernet, IP, and Frame Relay. While most applications and services have been migrated to the packet-based network, some, including voice and legacy applications, still rely on a circuit or a leased line for transport. The SPA-1CHOC3-CE-ATM and SPA-24CHT1-CE-ATM implement CEoP by transporting circuits over a packet-based network. The SPA-1CHOC3-CE-ATM and SPA-24CHT1-CE-ATM SPAs help service providers and enterprises migrate to one-packet networks that are capable of efficiently delivering both data and circuit services.
CEoP Frame Formats
The SPA-1CHOC3-CE-ATM, SPA-2CHT3-CE-ATM, and SPA-24CHT1-CE-ATM support the structured or Circuit Emulation Services over Packet Switched Networks (CESoPSN) and the Structure-Agnostic TDM over Packet (SAToP) encapsulations.
Circuit Emulation Services over Packet Switched Network Mode
The CESoPSN mode encapsulates the T1/E1 structured (channelized) services over PSN. The structured mode (CESoPSN) identifies framing, and sends only the payload, which can either be channelized T1s within DS3 or DS0s within T1. DS0s can be bundled to the same packet. The CESoPSN mode is based on IETF RFC 5086.
SPAs can aggregate individual interfaces and flexibly bundle them together. They can be configured to support either structured or unstructured CES modes of operation per T1/E1/J1 interface and clear-channel DS3 interface. Effective from Cisco IOS XE Release 3.6.0S, DS3 supports both the CESoPSN and the SAToP. They are supported on the 1-Port Channelized OC-3 STM1 ATM CEoP SPA channelized to T1 or E1 and on the 24-Port Channelized T1/E1 ATM CEoP SPA.
Each supported interface can be configured individually to any supported mode. The supported services comply with IETF and ITU drafts and standards.
The following figure shows the frame format in CESoPSN mode.
The following table shows the payload and jitter for the DS0 lines in the CESoPSN mode.

Overview of SAToP mode
The SAToP mode encapsulates the T1/E1 or T3/E3 unstructured (unchannelized) services over packet-switched networks. In unstructured (SAToP) mode, bytes are sent out as they arrive on the TDM line. Bytes do not have to be aligned with any framing.
In the SAToP mode, the interface is considered as a continuous framed bit stream. The packetization of the stream is done according to IETF RFC 4553. All signaling is carried out transparently as a part of a bit stream. The following figure shows the frame format in Unstructured SAToP mode.
The following table shows the payload and jitter limits for the T1 lines in the SAToP frame format.

To verify the SPA hardware type that is installed in your Cisco ASR 1000 Series Routers, use either the show interfaces command or the show diagcommand. A number of other show commands also provide information about the SPA hardware.
The following table shows the hardware description that appears in the show command output for each type of Circuit Emulation SPA that is supported on the Cisco ASR 1000 Series Routers:
SPA |
Description in the show interfaces Command |
---|---|
SPA-1CHOC3-CE-ATM |
“Hardware is SPA-1CHOC3-CE-ATM” |
SPA-2CHT3-CE-ATM |
“Hardware is SPA-2CHT3-CE-ATM” |
SPA-24CHT1-CE-ATM |
“Hardware is SPA-24CHT1-CE-ATM” |
