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

Features Benefits

• Up to 161 voice compression ratio
• VAD Silence Suppression
• Equipped with both TDM IP uplinks
• Supports any type of signaling including CAS and
  CCS
• Transparent to all telephony features including
  fax, modem, CLIP, IVR, MFC, etc.
• Compact, Scalable and Simple to deploy

• Maximum reduction of voice transmission costs
• No bandwidth consumed when channels are idle
• Seamless migration from todays TDM networks to
  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)
