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
Vmux Trunking Slide 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 module’s serial number

Features & BenefitsFeatures & Benefits
Vmux Trunking Slide 25
Features & Benefits
• Up to 16:1 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 today’s TDM networks to tomorrow’s IP networks
NO compromise of existing telephony features and NO retraining of staff
Minimizes Initial Investment & Collocation Costs
Vmux Trunking Slide 26
Advantages over standard VoIP Solutions (for trunking applications)
• TDMoIP multiplexing provides higher bandwidth savings (16:1) 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
Vmux Trunking Slide 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)
• Easy to use calculator for case-by-case estimation of compression ratio
