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-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

If there is a signifanct price difference I would note it (even if you chose not to use the numbers you can say something about this)

ido_m

price is lower for some configurations but higher for others, so I prefer not to mention it

Features & BenefitsFeatures & Benefits


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


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


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


Management Options

Management options:• ASCII Terminal

• Telnet *

• SNMP *

• RADview-SC/Vmux *

* - In band or Out of band
