Digitizing Analog Signals 1. Sample the analog signal regularly 2. Quantize the sample 3. Encode the value into a binary expression 4. Compress the samples to reduce bandwidth (multiplexing), optional step IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 13

Nyquist Theorem IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 14

Quantization IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 15

Quantization Techniques • Linear Uniform quantization • Logarithmic quantization Compands the signal Provides a more uniform signal-to-noise ratio • Two methods α-law (most countries) μ-law (Canada, U. S. , and Japan) IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 16

Voice-Compression Techniques • Waveform algorithms PCM ADPCM • Source algorithms LDCELP CS-ACELP IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 17

Example: Waveform Compression • PCM Waveform coding scheme • ADPCM Waveform coding scheme Adaptive: automatic companding Differential: encode changes between samples only • ITU standards: G. 711 rate: 64 kbps = (2 x 4 k. Hz) x 8 bits/sample G. 726 rate: 32 kbps = (2 x 4 k. Hz) x 4 bits/sample G. 726 rate: 24 kbps = (2 x 4 k. Hz) x 3 bits/sample G. 726 rate: 16 kbps = (2 x 4 k. Hz) x 2 bits/sample IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 18

Example: Source Compression • CELP Hybrid coding scheme • High-quality voice at low bit rates, processor intensive • G. 728: LDCELP— 16 kbps • G. 729: CS-ACELP— 8 kbps G. 729 A variant— 8 kbps, less processor intensive, allows more voice channels encoded per DSP Annex-B variant –VAD and CNG IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 19

G. 729 and G. 729 A Comparison • Both are ITU standards • Both are 8 kbps CS-ACELP • G. 729 more complex and processor intensive • G. 729 slightly higher quality than G. 729 A • Compression delay the same (10 to 20 ms) • Annex-B variant may be applied to either IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 20

Real-Time Transport Protocol • Provides end-to-end network functions and delivery services for delay-sensitive, real-time data, such as voice and video • Works with queuing to prioritize voice traffic over other traffic • Services include: Payload type identification Sequence numbering Timestamping Delivery monitoring IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 21

Real-Time Transport Control Protocol • Monitors the quality of the data distribution and provides control information • Provides feedback on current network conditions • Allows hosts involved in an RTP session to exchange information about monitoring and controlling the session • Provides a separate flow from RTP for UDP transport use IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 22

RTP Header Compression • RTP header compression saves bandwidth by compressing packet headers across WAN links IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 23

When to Use RTP Header Compression • Narrowband links • Slow links (less than 2 Mbps) • Need to conserve bandwidth on a WAN interface IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 24

Challenges and Solutions in Vo. IP IP Telephony © 2005 Cisco Systems, Inc. All rights reserved. Cisco Public 25

Reliability and Availability • Traditional telephony networks claim 99. 999% uptime • Data networks must consider reliability and availability requirements when incorporating voice • Methods to improve reliability and availability include: Redundant hardware Redundant links UPS Proactive network management IP Telephony © 2005 Cisco Systems, Inc.
