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

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)

Voice-Compression Techniques • Waveform algorithms PCM ADPCM

• Source algorithms LDCELP CS-ACELP

IP Telephony

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 kHz) x 8 bits/sample G.726 rate: 32 kbps = (2 x 4 kHz) x 4 bits/sample G.726 rate: 24 kbps = (2 x 4 kHz) x 3 bits/sample G.726 rate: 16 kbps = (2 x 4 kHz) x 2 bits/sample IP Telephony

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.729A variant—8 kbps, less processor intensive, allows more voice channels encoded per DSP Annex-B variant –VAD and CNG

IP Telephony

19

G.729 and G.729A 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.729A • Compression delay the same (10 to 20 ms) • Annex-B variant may be applied to either

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

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

RTP Header Compression

• RTP header compression saves bandwidth by compressing packet headers across WAN links

IP Telephony

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

DHCP Service Setup (Cont.): Phone Bootup The IP phone powers on

On the Cisco CME router a DHCP Scope can be configured. The scope should define the following:

The phone performs a Power on Self Test (POST)

• Range of available IP addresses

The phone boots up

• A default gateway

Through CDP the IP phone learns what the auxiliary VLAN is

• The address of the TFTP server

• The subnet mask

• DNS server(s)

The phone initializes the IP stack
