There are many different scenarios and permutations with regards to physically wiring cable modem termination systems (CMTSs). You could have a sparse mode where upstream (US) ports on the CMTS are kept separate, a dense mode where signal is fed to multiple US ports, multiple CMTSs on the same physical plant, or different card densities. These combinations affect what happens when provisioning, maintaining, and troubleshooting. tech news

To help ensure future profitability, leading cable operators are exploring how best to deliver new revenue-generating services while lowering capital and operational expenses (CapEx and OpEx). Many operators are looking to converged networks to improve efficiencies, especially when delivering new services and applications. Convergence at different layers can bring significant savings. tech news

The four most practical Internet connections for small businesses and branch offices are analog, ISDN, DSL, and Cable explained in this paper. Analog connections are the most basic form of Internet connectivity. ISDN (Integrated Services Digital Network), also a dial-up service, delivers up to 128 Kbps performance for faster Internet access and greater productivity. DSL (Digital Subscriber Line) provides high-speed Internet access at up to 8 Mbps (143 times faster than analog) over ordinary copper telephone lines. Cable is a shared high-speed connection, which leverages the cable TV lines, and is available primarily in residential areas. tech news

By implementing advanced spectrum management techniques, cable operators can increase throughput, reclaim bandwidth, deliver additional services, and generate new revenues from existing plant. This white paper discusses the business opportunities that operators can capitalize on by implementing advanced spectrum management. It defines the typical types of impairments operators must overcome, and provides an overview of spectrum management solutions from Motorola that allow operators to increase performance and revenue. tech news
