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)

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

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

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

22
RTP Header Compression
• RTP header compression saves bandwidth by
compressing packet headers across WAN links
IP Telephony

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

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

Console)config-if)#switchport access vlan 12
Console(config-if)#switchport mode trunk
Console(config-if)#switchport voice vlan 112
Console(config-if)#spanning-tree portfast
• 802.1q trunking is enabled on the port
• The access VLAN is used for the PC plugged into the IP
phone
• The voice VLAN is used for voice and signaling that originates
and terminates on the IP phone
• Spanning tree portfast enables the port to initialize quickly

DHCP Service Setup
Dynamic Host Configuration Protocol
• Assigns an IP addresses and subnet masks for one
or more subnets
• Optionally can assign a default gateway
• Optionally can assign DNS servers
• Optionally can assign other commonly used
servers
• The DHCP scope can be customized to assign a
TFTP server to IP phones
• Best practice is to configure a DHCP scope for the
IP phones

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 subnet mask
• The address of the TFTP server
• DNS server(s)
The phone initializes the IP stack
