Our local loop providers give fiber optic connectivity between our provider's Kansas City Internet Data Centers and their transit providers. The local loop providers are MCI/WorldCom and Southwestern Bell. Both providers have installed OC-12 multiplexors within their Kansas City Internet Data Centers. Thus, they have the short-term capacity to upgrade their bandwidth since they have the local loop capacity. The local loop capacity between their 2 OC-12s total 1.24Gbs.

For redundancy, our providers have propagated their DS-3 transit and long-haul circuits between these two local loop providers. Thus, in the unlikely event an OC-12 fails, or the local loop fiber is cut, we still have connectivity. Below is the current delegation of circuits:

MCI/WorldCom OC-12 Local Loop
UUNet Technologies Full DS-3 Transit Circuit #1
UUNet Technologies Full DS-3 Transit Circuit #2

Southwestern Bell OC-12 Local Loop
Sprint Communications Full DS-3 Transit Circuit
Global Crossing Full DS-3 Transit Circuit
Universal Access Full DS-3 Long-Haul Circuit

While utilizing two diverse local loop providers for transit and long-haul circuits, our providers have increased their telecommunications costs, but also minimized the risk of communications failure. Both providers maintain separate OC-12 multiplexors, on seperate SONET rings, with the point of entry in the Mainmark building diverse as well. These local loop investments are examples of the commitment to "reliability before profitability".
