Vmux-2120Scalability Port Activation
  • Vmux-2120 can be ordered with only part of the 16
    E1/T1 ports activated, and expanded in the future
    by software license
  • Customer Benefits
  • Cost saving no truck rolls for future expansion
  • Easy stock management
  • Fast deployment of additional trunks
  • Software keys emailed immediately upon order
    (zero lead time)
  • Unlicensed ports can be pre-configured for future
    activation

17
Vmux-2120Port Activation How does it work
  • EXAMPLE Customer starts with a fully redundant
    Vmux compressing 8 T1s, to be expanded in the
    future to 12 T1s
  • Present 1 x VMUX-2120/ACR/VC/16T1/8SK
  • (chassis with 16 physical T1 ports, of which 8
    are activated)
  • 1 x VMUX-2120-M/VC/16T1/8SK
  • (redundant module with 16 physical T1 ports, of
    which 8 are activated)
  • Future 2 x VMUX-2120-LIC/T1/4SK
  • (software key for activating additional 4 T1
    ports)
  • Notes
  • Partial port activation is available for the 16
    port version only
  • Software key is linked to the modules serial
    number

    tomorrows IP networks
  • NO compromise of existing telephony features and
    NO retraining of staff
  • Minimizes Initial Investment Collocation Costs

26
Advantages over standard VoIP Solutions (for
trunking applications)
  • TDMoIP multiplexing provides higher bandwidth
    savings (161) than any standard VoIP solution
  • Full signaling transparency ensuring seamless
    integration with no retraining costs or lost
    functionality
  • Provides bandwidth reduction even without
    migrating to IP networks
  • Backup between IP and TDM uplinks with the same
    bandwidth savings
  • Single compression cycle end-to-end
    (Super-Tandem)
  • Better resiliency to packet loss
  • Supports bandwidth control mechanisms to better
    cope with situations of bandwidth overflow

27
Bandwidth Considerations
  • User configurable parameters
  • Voice codec used (between 5.3k 64k)
  • Packet size (tradeoff between bandwidth delay)
  • Packet type (AAL2oMPLS header - smaller than
    TDMoIP - for TDM networks only)
  • Application dependant parameters
  • Number of compressed voice channels in a single
    bundle (The more channels, the less header
    overhead)
  • Actual silence percentage (typically 50 in
    fixed line networks, 35 in cellular networks)
