Where does it fit in?
TDM Emulation
High-rate (SONET/SDH)
low-rate (T1/E1/T3/E3)
structure-agnostic
structure-aware
CEP
TDMoIP
CESoPSN
SAToP
3
Why structure-aware?

• might need access to TDM constituents
• packet loss concealment
• data channels
• more robust synchronization
• frame sync regenerated
• multiframe sync maintained
• integrity of CAS signaling guaranteed

4
2 structure-aware protocols?

• CESoPSN
• minimum intervention
• simple to implement
• TDMoIP
• enables interworking with ATM CES networks
• has dynamic bandwidth (AAL2) mode
• integrity of CAS signaling guaranteed

5
Proposal

• Request WG to
• advance both CESoPSN and TDMoIP
• as information working group items
