How can service provider maintain older legacy equipment while gradually upgrading to Carrier Ethernet?

President Donald Trump has committed to invest heavily in infrastructure in an attempt to accelerate economic growth in the United States and create jobs.

“We are going to fix our inner cities and rebuild our highways, bridges, tunnels, airports, schools, hospitals,” Trump said on election night last November. If the trillion-dollar plan materializes, it is believed it will also include heavy investment in wireline broadband.

A report published in January 2016 by the Federal Communications Commission (FCC) indicates that 10 percent of all Americans and 39% of rural Americans have no access to broadband service. The FCC concludes that advanced telecommunications capability is not being deployed to all Americans in a reasonable and timely fashion.

With the forecasted upgrading, communications service providers (CSPs) are likely to try to convince their business customers to leave behind their legacy SONET-based services and move to a high bandwidth service based on Carrier Ethernet or MPLS networks. However, the reality is that not all clients will be interested in this change.

Experience shows that utilities, government entities and transportation companies are not rushing to upgrade their networks and some of them prefer to continue using TDM and SONET.

In fact, there are still end-users that require T1, T3 or fractional T-1 for their communications. Utilities and transportation companies still have low speed requirements for SCADA, 4 wire E&M, etc. These companies claim that their technicians know the old equipment inside out and that it is still functioning with no need to replace it.

In order to meet this challenge, Telco Systems is offering service providers its Circuit Emulation Service (CES) “Family of Products” technology which makes it possible for service providers to replace their SONET-based access network to MPLS or Carrier Ethernet without giving up on their traditional business customers.

Telco Systems CES Technology and Standards

Using this technologies, enables service providers to offer options for the end-user such as maintaining their Legacy equipment while migrating to the packet based network or keeping their legacy equipment and connecting into the packet based network.

Telco Systems provides several individual solutions that can work together as one complete solution. The Telco Systems Family of CES products support the following: MEF Carrier Ethernet 2.0 (CE 2.0), MPLS, Layer 3 VPN (L3VPN), include smart SFP’s. The CES solution supports ANSI, T-1, DS-3, OC-3, OC-12 over L2 or L3 and ETSI, E1, E3, STM1, and STM4.

With Telco Systems CES supported products and solutions there are no stranded assets as they support multiple technologies within the same equipment. As a manager, making the decision to upgrade you can be sure that you will be spending your money wisely because once you move away from TDM or SONET you don’t have to remove equipment just plug into a different port and re-configure.
