Facilitating telecommunications continuity by providing
redundant combinations of local carrier T-1 lines,
microwaves and/or coaxial cables to access the local
communication loop is:
A. last mile circuit protection.
B. long haul network diversity.
C. diverse routing.
D. alternative routing.
Answer / guest
Answer: A
The method of providing telecommunication continuity through
the use of many recovery facilities providing redundant
combinations of local carrier T-1s, 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 availabilty utilizing T-1
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.
