ICAN is a SONET based, special access transport service which terminates over STS entrance ring capacity at the customer primary location. ICAN is provided with two levels of survivable, Basic & Premium. ICAN "Basic" circuit designs provide fiber link protection for customer’s DS1 and higher bandwidth services. ICAN "Premium" circuit designs will include fiber link and intermediate electronics protection for customer’s DS1 and higher bandwidth services. ICAN will be packaged in a manner that requires minimum service volume levels (336 DS1s or equivalents) at each carrier POP, thus supporting the nature of the service as a network, rather than individual circuit offering. For individual subtending services, the ICAN SONET design is provided as ON-NET or OFF-NET. ON-NET guarantees the selected level of survivability from the POP (or Network Aggregation Point) to the end user building. OFF-NET guarantees the selected level of survivability over the POP entrance ring and as far into the network as facilities allow. ICAN is a LATA wide network offering in the South, and a POP wide service in the North. Bell Atlantic requires a five-year service commitment from the customer.

The available POP and EU Premises network
interface combinations are:

The ICAN ON NET architecture consists of four basic network components: (1) an entrance facility (into the carrier’s POP) provided over a self-healing diverse fiber path SONET ring (based on the design of ICSR); (2) shared Digital Cross-connect Systems (DCS) for multiplexing and grooming of DS1 Connecting Facility Assignments (CFA); (3) shared InterOffice Facility (IOF) provided over a self-healing diverse fiber path SONET ring; and (4) a shared local loop facility provided over a self-healing diverse fiber path SONET ring which connects to the IOF at two Bell Atlantic wire centers (Customer Access Ring - CAR).

ICAN is a Bell Atlantic Intellilight service. Entrance and subtending special access services are provided over survivable SONET network facilities that are supported by Bell Atlantic’s one-minute service guarantee. Therefore, should an ICAN circuit be interrupted for one minute or more in a given month, due to a BA problem, the customer will be credited 100% of the monthly rate for the affected service.
