Circuit Emulation Service over Packet-Switched Network
CESoPSN encapsulates structured TDM signals as PWs over public switched networks (PSNs). It complements
similar work for structure-agnostic emulation of TDM bit streams, such as SAToP. Emulation of circuits saves
PSN bandwidth and supports DS0-level grooming and distributed cross-connect applications. It also enhances
resilience of CE devices due to the effects of loss of packets in the PSN.
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.
Each supported interface can be configured individually to any supported mode. The supported services
comply with IETF and ITU drafts and standards.
