Bandwidth to Support Convergence
Convergence means combining or converging voice, data and video onto a single network. Enterprises usually need to expand their LAN bandwidth and set up a QoS or Quality of Service priority system to give priority to real-time streams such as telephone calls or video conference feeds, which are more sensitive to network delays than data transfers. Most often, the common protocol for convergence is IP.

What is Ethernet over Copper
Ethernet over Copper, or EoC, uses copper transmission lines rather that fiber optics. T1 lines are most often used to transport mid-band Ethernet signals in the 1 to 10 Mbps bandwidth range when provisioning fiber optic lines is too expensive.

What is PBT?
PBT stands for Provider Backbone Transport. It's an adaption of Ethernet to extend Layer-2 switching into the WAN transport network. PBT was pioneered by Nortel and will be standardized by the IEEE as PBB-TE.

How does managed security work?
Companies that specialize in network security install VPNs and managed firewalls that they remotely monitor from a network operations center. A dedicated security team that specializes in knowing what threats are out there, when they are coming for your network and what to do to mitigate the threat provides the vigilance for a multitude of clients.

Will Carriers "Light Buildings"?
Some will if their closest point of presence (POP) is within a mile or so of your location. The farther away you are, the higher the bandwidth commitment needs to be in order to justify the carrier's construction costs.
