Functions such as channel selection, transmit level adjustment, frequency effect compensation and bandwidth allocation are done automatically and periodically under the control of the LCe. This provisioning server enables cable operators to perform software upgrades over the network. Access to the network is guaranteed, regardless of traffic when using the LCe. The cable TV data channel is part of the worldwide Internet and the LCe provides the connectivity. A very high performance bridge architecture provides interconnectivity between multiple data channels and an Internet router.
Address filtering at the network layer is an operator configuration option.
The open and scalable network architecture enables connectivity via switch, router or directly through the Ethernet port. Bay Networks LCe system is frequency agile over its operating range of 8.75 to 42 MHz upstream and 54 to 750 MHz downstream in 250 KHz increments. Data channels can be moved in frequency, allowing a dynamic management of spectrum. Functionality The LCe features a two-channel integrated controller. It also provides internetworking access points and frequency translation with local and remote spectrum management, along with dynamically allocating reservation data bandwidth.
