To allow interoperability between the existing telephone network and Internet Telephony (IT) it is necessary for the signaling performance to be comparable to that of the current standards to avoid introducing degradation in the service. In this Internet Draft, we highlight the problem of providing high-quality signaling across an IP network that is built on a SONET infrastructure. We show that there are cases where the current PSTN standards are not satisfiable by a naive mapping of the IT signaling directly to the UDP or TCP transport protocols, even neglect- ing packet loss in router queues.
