Why Voice over IP?
• Traditional TDM– High recurring maintenance costs
– Monolithic switch design with proprietary interfaces
– Uses dedicated, voice-only bandwidth in HFC network
• IP– Many services, one network
– Leverages existing data infrastructure
– Enhanced services
– Open standards

Why VoIP over Cable?
• Deployed architecture– Existing Physical network
– Existing Data Network
– Available bandwidth
• Widely accepted standards– DOCSIS, Euro-DOCSIS
– Enables construction of networks with “Best of breed” equipment – don’t have to buy everything from one vendor
• Provides MSO’s with “Triple Play” of Video, Data and Voice helping to reduce customer churn

Traditional Telephony Network
• Class 5 Switch– Provides ‘line-side’ connectivity
– Implements call features (*69, *72, Call-waiting, etc.)
– Acts as SS7 Signaling Switch Point (SSP)
– Bearer traffic carried on Inter-Machine Trunks (IMT)
• Line Side Concentration– Facilitated by GR-303
– 4 to 1 concentration – 4 subscribers per DS0
– RDT aggregates analog twisted-pair lines
• End-to-end connection– DS0 (64kbps PCM) is allocated on all links in network for
duration of call, forming a ‘virtual circuit’.

Voice Sampling and CODEC’s
• Digitally encoded audio – Audio is sampled at 8000 samples/sec– Samples for regular time intervals (‘time slices’) are
assembled into frames, frame size varies according to Codec (codec = coder/decoder)
– Sample data may be compressed depending on Codec
• Example Codecs– G.711 – corresponds to PSTN DS0 64kbps – low complexity– G.729A – 8x compressed - 8kbps - medium complexity– G.729E – enhanced – 11.8kbps – high complexity– G.728 – 16kbps – high complexity
• Each packetization interval, sampled audio is encapsulated into an IP packet and transmitted
999© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
Packetization Interval Tradeoffs
• Short interval– Lowers end-to-end latency
– Lost packet contains smaller amount of actual voice data, less impact on voice quality
– Higher overhead, less efficient use of network bandwidth
• Long interval– Greater network bandwidth efficiency
– Fewer packets = less stress on packet forwarding network elements
• Most deployments use 20ms packetization interval
101010© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
VoIP Transport
• Packet Encapsulation– RTP – Real Time Protocol
• Provides timestamp and packet sequence numbering so destination applications can reassemble and playback speech
– UDP – User Datagram Protocol• Provides port number addressing, so that the correct
destination application can receive the packet• Provides data integrity via CRC (Cyclic Redundancy
Check)– IP – Internet Protocol
• Provides routing info for packets to get to appropriate destination
• Provides packet prioritization

Network Requirements
• Deliver a service that approximates that provided by the synchronous PSTN, on an inherently asynchronous IP network
• In simplest terms, ensure the following:– Low latency (minimal delay in delivering packets)
– Low jitter (expected arrival vs. actual arrival time)
– Very few dropped packets

PacketCable Overview
• Founded in late 1997 to address the need for a multimedia architecture
• Requires a DOCSIS 1.1 access network with cable modem and CMTS as the core delivery components
• Addresses issues such as:–Signaling for services
–Media transport at variable QoS (Quality of Service) levels
–Security
–Provisioning of the client device
–Billing
–Network Management
151515© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
Packet Cable Architecture Highlights
• Focus is on a standards based solution
• Flexible Architecture, ability to “plug and play” different components
– Each functional element of the solution is described individually, allowing for the MSOs to implement best of breed
– At the same time credence has to be given to a solution that is also operable as one end to end solution, and that needs to be weighed when defining the solution
• PacketCable certifies different features and functionality during its certification waves
– Cert Waves include CMS, MGC, MGW, eMTA, Calea etc
– Basic Interoperability is tested

Back-office Server Components
•ANS (Announcement Server) manages and plays customized informational messages
•Consists of an ANC (Announcement Controller) and an ANP (Announcement Player)
•CALEA Server allows for lawful electronic surveillance to be initiated:•Provides a gateway to the law enforcement entity (e.g., the FBI)
•Initiates surveillance per subscriber with the CMS
•Collects call detail information from the CMS, CMTS, and PSTN gateway
•Collects call content information from the CMTS and PSTN gateway
•Other back-office servers may include servers for such functions as voicemail and directory listing
242424© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
Operations Support Systems (OSS) Components
• RKS (Record Keeping Server) collects event messages From CMS, MGC and CMTS and interfaces with a billing system
• DHCP server allocates IP addresses
• DNS is required for naming the PacketCable components
• KDC (Key Distribution Server) for security keys
• A provisioning server supporting SNMP-V3 drives the MTA initialization and provisioning from subscriber data using PacketCable Provisioning MIBs.
• CMS provisioning support is described but not fully specified
• TFTP is used to download device configuration files (driven by provisioning)

Interfaces Defined by PacketCable
• Network-Based Call Signaling (NCS) – Interface between MTA and CMS, a MGCP profile
• Trunking Gateway Control Protocol (TGCP) – Interface between MG and MGC, a MGCP profile
• Event Messages Interfaces – event message carries network info over RADIUS for CDR (from CMS, CMTS, & MGC to RKS) & CALEA (from CMS, CMTS, & MGC to DF)
• Dynamic QoS Specification (DQoS) – various QoSinterfaces defined between PacketCable components.
• Common Open Policy Service (COPS) – Transports DQoS between Gate Controller (QoS management component in CMS) and CMTS (IETF RFC 2748)

Bearer Traffic Highlights
• Bearer traffic goes directly to the trunking gateway for off-net calls or to the terminating MTA for on-net calls
• Traffic follows the best path defined by the network and the IP routing protocols
• Bearer Traffic is not forced through a central location but rather through the optimum path to its ultimate destination, minimizing jitter and delay
292929© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
PacketCable DQoS
• Dynamic Quality of Service, arguably the single most important PacketCable specification
• Creates an association between application specific signaling (NCS), subscriber information, and use of DOCSIS 1.1 QoS
• Participating network elements include CMS, CMTS and eMTA
• Introduces Concepts of Gates on the CMTS– COPS(Common Open Policy Server) signaling for Gate-Alloc
and Gate-Set messages
– RADIUS signaling for Gate Open and Gate Close messages
303030© 2004 Cisco Systems, Inc. All rights reserved.Presentation_ID
DQoS Gates
• Ephemeral (exist _only_ for duration of call)
• Will automatically be deleted if not ‘used’eMTA _must_ send DOCSIS DSA/DSC within short time-
frame identifying Gate-ID to be used.
• CoordinatedWhen both endpoints are on the cable network, Gate Open,
Gate Close messages are sent by CMTS such that other CMTS knows far-end call leg has been constructed.
• DOCSIS DSA/DSC must be within QoS limits specified within Gate spec.
