LEASED LINE
REPLACEMENT

Move away from Leased Private Lines
by utilizing your existing network while
preserving your existing Analog and TDM
interfaces. No service disruption and no
training for new devices.

The Trouble with Leased Private Lines

As Telco leased lines become obsolete and increasingly expensive to maintain, companies are looking for alternatives that eliminate their dependency on leased lines while maintaining their existing network.

Replacing Leased Lines

Virtual Access products convert leased line interfaces to Ethernet allowing you to move to your IP/MPLS network while your customers keep their legacy equipment.

Using alternate networks that are more cost effective, easier to maintain, or owned internally, you can move away from Leased Lines and still connect existing Analog and TDM interfaces.

Utilize Existing IP/MPLS Network

Replace Leased Lines Utilizing Exisiting IP Network
Connect multiple legacy interfaces via an existing IP or MPLS network


Preserving Equipment

Companies are choosing to preserve existing equipment for many reasons:

  • Existing maintenance contracts are not set to expire
  • Training on new equipment is too disruptive
  • Equipment is relatively new
  • Cost of new equipment and set up time
