Packet- based Voice over Internet Protocol (VoIP) services are becoming more widely deployed in service provider networks. Voice quality for these services often come into question, largely as a result of many factors including the compression algorithm, delay, jitter, suppression of silence, comfort noise generation, speech encoding, packet loss, and delay incurred from packetizing / depacketizing voice samples. This paper discusses how the 5E-XC Optical Interface Unit - Internet Protocol (OIU-IP) can address some of these concerns. The 5E-XC OIU-IP is a packet trunking peripheral for the 5ESS switch and addresses voice packetization, management of packet jitter, silence suppression, comfort noise generation, and echo cancellation.
