Migrating multi-service ATM to Optical Network

In the 90s, ATM was the multi-service technology par excellence. ATM offers a solid quality of service mechanism that allows it to carry voice and video, in addition to Ethernet and IP network traffic. However, as a result of the significant increase in data traffic volume, along with the rapid implementation of Gigabit Ethernet technology, ATM is no longer considered a backbone technology for the future. This is the reason why, for the last several years, there has been a clear trend towards the migration of ATM networks to other technologies.

If an organization has an ATM Network that uses its own or leased fiber-optic installation, TELNET recommends migration towards an Optical Multi-service network. The following are a few of the reasons for this evolution:

• Capacity. Apart from the cost of ownership, the factor that most affects ATM has been its limitation to speeds of 155Mbps and 622Mbps for data transport. Optical networks have no speed limitations.  TELNET offers optical adapters to interconnect networks at speeds ranging from 1Gbps up to 10Gbps, and we are currently working on a new 40Gbps service module.
• Multi-service. Our optical solutions are multi-service. Using our CWDM architecture and MetroSAE it is possible to integrate any service and protocol, from E1 up to 10G interfaces, including SDH, ATM, MPLS, Fiberchannel, or FICON, among others

• Protection of investment. Institutions that have made significant investment in traditional voice systems can benefit from our solution, extending the life of their telephone switchboard network by integrating them into the TELNET optical network.

• Non-traumatic migration. In plans for migration from an ATM data network to a Gigabit/10G network, it is possible to keep both networks operating simultaneously over the same optical network, and to carry out the migration in an orderly fashion without negatively affecting the service.
