Location: Penn Telecom/Voice & Data Services/Broadband Services/ATM Services

Penn Telecom is glad to offer ATM cell relay services to its customers. Penn Telecom currently supports its DSL network with our ATM core and will soon also use ATM to support voice and data services to our customers.

What is ATM?
ATM (asynchronous transfer mode) is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology. Individually, a cell is processed asynchronously relative to other related cells and is queued before being multiplexed over the transmission path.

Because ATM is designed to be easily implemented by hardware (rather than software), faster processing and switch speeds are possible. Speeds on ATM networks can reach 10 Gbps. Penn Telecom currently offers ATM Cell Relay circuits that range from DS1 speeds of 1.544 Mbps up to OC-12c speeds of 612 Mbps.
