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 long-distance 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.
