There are several methods of providing telecommunications
continuity. The method of routing traffic through split
cable or duplicate cable facilities is:
A. alternative routing.
B. diverse routing.
C. long-haul network diversity.
D. last mile circuit protection.
Answer / guest
Answer: B
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-1 circuits among
the major long-distance carriers. It ensures long-distance
access should any one carrier experience a network failure.
Last mile circuit protection is a redundant combination of
local carrier T-1s, 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 also is utilized.
