There are several methods of providing telecommunications continuity. The method of routing traffic through
split cable or duplicate cable facilities is called:

A.
alternative routing.

B.
diverse routing.

C.
long-haul network diversity.

D.
last-mile circuit protection.

Explanation:
Diverse routing routes traffic through split-cable facilities or duplicate-cable facilities. This can be accomplished
with different and/or duplicate cable sheaths, if different cable sheaths are used, the cable may be in the same
conduit and, therefore, subject to the same interruptions as the cable it is backing up. The communication
service subscriber can duplicate the facilities by having alternate routes, although the entrance to and from the
customer premises may be in the same conduit. The subscriber can obtain diverse routing and alternate routing
from the local carrier, including dual-entrance facilities. This type of access is time consuming and costly.
Alternative routing is a method of routing information via an alternate medium, such as copper cable or fiber
optics. This involves use of different networks, circuits or end points should the normal network be unavailable.
Long-haul network diversity is a diverse, long-distance network utilizing T-l circuits among the major longdistance carriers. It ensures long-distance access should any carrier experience a network failure. Last-mile
circuit protection is a redundant combination of local carrier T-ls, microwave and/or coaxial cable access to the
local communications loop. This enables the facility to have access during a local carrier communication
disaster. Alternate local-carrier routing is also utilized.
