                                      IP Network

     • Voice over IP (VoIP) samples 10 – 60ms of voice with an
       Analog-to-Digital conversion process (CODEC). This is similar
       to the way the phone company does it today with PCM (Voice
       over T1/E1).
     • These samples are placed into an IP packet and sent over the
     • A far-end device reassembles the voice stream on the other

Signalling Standards Snapshot

     Signaling protocols defines how VoIP equipment communicate to actually
      set-up, establish and release telephone calls over IP networks. For
      example – Ring, Talk and Hang-up.
     H.323
         The oldest and most widely supported call control protocol.
                 Current Version is v4 (we support it now!)
                 Is actively enhanced by the international standards community
         Offers the most interoperability between 3rd party equipment.
         Business focused
     SIP
         The newest of the call control protocols
                 IETF (Internet based); looks like html; most extendable
                 Messaging for all types of user devices (phones, PC, GSM)
         Carrier/CLEC focus
         We support it today!
     MGCP
         Oriented towards softswitch carrier architectures
                 Focuses on the central site over CPE
         Supported in SmartNodes today!
VoIP Terms Defined (1)

      Softswitch
     Call control and route server in a VoIP network providing user AAA
     services and intra-network call switching. This is Independent of the VoIP
     protocol (H.323, MGCP, SIP).
      Gatekeeper (GK)
     H.323 specific term. The GK is responsible for the management of the
     users (clients) and gateways in his H.323 area (zone). Implemented as
     software on a server or integrated as a function in a Gateway.
      Gateway (GW) (This is what SmartNodes do!)
     Signaling or Media-Gateway (may be combined in one equipment)
     provides conversion between different networks-protocols or technologies.
      H.323 Client
     Terminal in an H.323 network. IP-Phone or Soft-Phone (e.g. NetMeeting).
      AAA
     User Authentication, Authorization, Accounting. Required functions for a
     commercial VoIP Service. Carrier centric and provided by Gatekeeper.
VoIP Terms Defined (2)

      RAS
     Registration Authentication Status: H.323 Sub-protocol used to register “log-in” an
     H.323 Gateway or Client at the Gatekeeper
      SIP User Agent
     SIP Equipment or software representing an end-user. The user agent includes a a
     SIP client (to initiate calls) and SIP server (to terminate calls). This is “inside” a
     SmartNode gateway.
      SIP Network Server
     SIP Equipment or software in the network required to register and localize User
     Agents and their end-users. A SIP Network Server can operate in redirect or proxy
     mode. This is a server box routing calls.
Telephony Terms

    BRI, S0, S/T     2 B + 1 D channel > 2 voice connections
    E1, PRI, S2m 30 B + 1 D channel > 30 voice connections
    T1, PRI          23 B + 1 D channel > 23 voice connections

Building Blocks for QoS (2)

    For Example: Traffic Shaping
    A Shaper can limit a Traffic Class to a defined bandwidth
    Frees Bandwidth for real-time (voice) traffic without packet loss
    Improves the Performance of interactive Applications
    Very usefull for short connections e.g Web requests

          Bandwidth                                               Bandwidth

Smart combination of QoS and VoIP

    The integration of QoS Router and VoIP Gateway makes things
    much easier
    • Traffic Classes are defined at network interfaces
    • No tagging necessary for point-to-point links
    • Optimal bandwidth usage and control
