CCITT/ANSI Voice Packetization Protocol

This paper introduces the packetized voice protocol G.PVNP/T1.PVP which is being standardized in both the CCITT and T1Y1. At layer 2, G>PVNP/T1.PVP extends ISDN LAPD protocol to include packetized voice, thereby potentially allowing the integration of voice and data traffic. Layer 3 specifies procedures to deal with voice-band data traffic and to handle channel-associated signaling.
