Facilitating telecommunications continuity by providing redundant combinations of local carrier T- 1 lines, microwaves and/or coaxial cables to access the local communication loop:

A. last-mile circuit protection.

B. long-haul network diversity.

C. diverse routing.

D. alternative routing.

Explanation:

The method of providing telecommunication continuity through the use of many recovery facilities, providing redundant combinations of local carrier T-ls, microwave and/or coaxial cable to access the local communication loop in the event of a disaster, is called last-mile circuit protection.

Providing diverse long-distance network availability utilizing T-l circuits among major long- distance carriers is called long-haul network diversity. This ensures long-distance access should any one carrier experience a network failure. The method of routing traffic through split-cable facilities or duplicate-cable facilities is called diverse routing. Alternative routing is the method of routing information via an alternative medium, such as copper cable or fiber optics.
