FINAL TEST

Question 1

How should lighting for a telecommunications space be powered to reduce noise on the equipment circuits?

Answer 1

Lighting and convenience outlets (which may be used for hand tools and other service purposes) may place noise on the power circuits and should be kept electrically separate from the electronic equipment outlets. -

Question 2

Answer 2

*Optimum use of building space

*Improved overall appearance of the building

*A good work environment allowing for fast and easy installation and maintenance work

*Uniform performance assessment and familiar facilities for personnel

¥Scalability to serve future standards-compliant technologies

Question 3

In a single-building SCS, what transition is marked at the demarc?

Answer 3

If the SCS installation covers only one building, then the EF is the demarc between the provider’s ownership and the client’s ownership. EF marks the boundary where the service provider’s ownership ends and the customer’s ownership begins.

Question 4

True or false: An SCS should be device dependent.

Answer 4

False.

SCS infrastructure is intended to serve a wide range of uses and should not be device or application dependent.

Question 5

Which regulations, in the United States, govern the connection of terminal equipment to an SCS?

Answer 5

Part 68 of the FCC rules (47 C.F.R. Part 68).

Specific to the SCS field, the FCC covers the connection of terminal equipment to the public and private line network. It specifies that wireline telecommunications carriers must allow all TE to be connected directly to their networks, provided the TE meet certain technical criteria for preventing four proscribed harms. These harms are electrical hazards to operating company personnel, damage to network equipment, malfunction of billing equipment, and degradation of service to customers other than the user of the TE and that person’s calling and called parties. The FCC also has accepted the Universal Service Order Code (USOC) descriptions of connecting jacks used in connecting terminal equipment.

Question 6

Which part of NFPA 70, the code that protects against electrical hazards, covers rules for installing optical fiber cables and raceways in an SCS?
