If you're renting the copper to provide a multi-tenant office building high-speed Internet access, you don't want to have to rent and manage separate lines for each customer. With ADTRAN's FramePort products, you can generate more revenue per circuit by oversubscribing a number of high-speed data users on a single T1. Using industry-standard Frame Relay technology, you can take advantage of the traffic and idle time to get more customers on a T1 than ever before possible. Using the FramePorts in this way, you may support as many as 96 users at up to 144 Kbps or 24 users at up to 768 Kbps. FramePorts are designed to be compatible with D4 channel banks, so there's no additional costs for upgrading your infrastructure. Management is cost-effective, too, with comprehensive SNMP-based configuration, provisioning and test systems.
