16Vmux-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
17Vmux-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

23Gmux-2000 Module View
24Features Benefits
25Features 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
26Advantages 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
27Bandwidth 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)
