These facilities are often not regulated by the government.Customer connectivity to a Point of Presence these days is usually over Metro ethernet or SONET rings. Most of the time, it refers to a building that is carefully selected to host internet circuits between various carriers. Point of Presence does not always carry the same loaded meaning that Central Office does. Basic / Enhanced 911 is routed through the Central Office.They always have responsibility for maintaining last-mile transport to customers.NEBS requires routers / switches to have front-to-back cooling and other features that comply with Telecordia's requirements. NEBS-compliant equipment is a big deal to RBOCs and incumbents. Construction and installations within a Central Office normally comply with Telecordia standards, such as GR-63 NEBS.Incumbent carriers in many other countries are also regulated in a similar manner. Because the Central Office is associated with the Bell companies, they are heavily regulated by the government.Telephone copper pairs star out of the Central Office to normally about 15,000-18,000 feet however, you can also star the copper out from a DLC can to cover a much larger area, because the DLCs can be connected via fiber. Originally they housed circuit-switching technologies these days they have similar routers and switches as you'll see in a Point of Presence. The differences between them have much more to do with historical context.Ĭentral Office is a term that has deep roots in the Bell companies, where the Central Office also called a telephone exchange. I also think Intrado has equipment for CLECs to provide 911 services.
Function - Basic / Enhanced 911 is still processed through the Central Office however other CLECs can trunk customers' 911 calls back to the Public Service Answering Point (PSAP) via the local Central Office.What is the difference between this two (in distance and function).
