Hot cutting, also known as a hot cut, refers to the process of deliberately切断 a copper loop from one telecommunications company's switchboard and reconnecting it to a different carrier's switchboard without any significant outage period. This type of cut is typically carried out in the local exchange industry to facilitate the quick switching of circuits between different service providers.
The term "hot cut" is often used in the local exchange industry to describe the near-simultaneous disconnection of a Verizon working loop from one carrier's switch, and the reconnection of that loop to a port on a different carrier's switch, without any significant out-of-service period. Initially, the loop may be any of: (a) a Verizon retail loop, (b) a loop being used to provide resold service, (c) a part of a UNE-P arrangement, or (d) a UNE-L connected, through a CLEC collocation arrangement, to a CLEC switch, and being used by that CLEC to provide local exchange service to one of its customers. After the cutover, the loop would generally be a UNE-L connected through to a different CLEC switch.
There are several main types of hot cut processes, including:
-
Basic Hot Cut Process: This process involves a Customer Limited Switched Line (CLSL) submission, which indicates the customer's desire to utilize the existing loop. Once the submission is completed, Verizon generates three related service orders: a disconnect order to discontinue the existing retail service, a change order to establish a UNE-L loop for the CLEC, and a record order detailing listing information, including E911 data. The CLSL is either electronically flowed through Verizon's ordering systems or manually processed by a Network Management Center (NMC) representative. If any issues arise, the NMC representative can communicate with the Remote Control Center Company (RCCC) via telephone calls or eWPTS.
-
Coordinated Hot Cut Process: This process is similar to the Basic Hot Cut Process, except that the RCCC will create an open bridge for the use of the CLEC and Frame Technicians during the hour surrounding the hot cut. An additional process called a Coordinated Hot Cut Process is also available in the West only. This process is the same as the Coordinated Conversion process described above, except that the coordinator in the RCCC will create an open bridge for the use of the CLEC and the Frame technicians for the hour surrounding the hot cut.
Hot cutting is a critical component of the telecommunications industry, enabling the rapid and efficient switching of circuits between different providers. By using hot cutting technology, carriers can minimize downtime and ensure that their customers experience minimal disruption during routine maintenance or upgrades.
