In reviewing your client's network needs for today and 5 years into the future, you note their current specs call for a 1Gb/s network within a campus environment, with little or no possibility of any increased bandwidth demands until they move to their planned future site. The building is not large, and the cable lengths will not exceed 550 m (1804 ft). Your recommendation for the fiber to be installed in the backbone is:
Which class of the system applies when the premise only has a single equipment room (ER), and it is the only telecommunications space administered?
Class ________ administration provides for the telecommunications infrastructure administration needs of a single building, or of a tenant served by a single or multiple. It also includes administration for backbone cabling, systems, and.
You are designing a cabling containment system installed overhead in a new data center. The main or prime purpose of the system will be to manage fiber optic cabling between cabinets. You have a choice of designs of the containment system. In view of the prime purpose of containment system, your first choice of design will be one that:
What type of redundancy provides two complete units, modules, paths or systems for every one required for a base system.
What type of redundancy provides two additional units, modules, paths, or systems in addition to the MINIMUM required to satisfy the base requirement.
Coupling with electrical circuits can create inductive interference to telecommunications facilities. Which of the following can decrease the coupling effect?
One interior TTY must be provided at locations defined as public accommodations with ________ or more pay telephones.
What is the air change requirement for a tunnel of 610 m (2000 ft) long with a diameter of 3.4 m (11 ft)?
You are placing two 423 mm (19 in) relay racks with a 152 mm (6 in) vertical management panel on each end and a 12 in vertical cable management panel between the racks. The rack lineup begins against a wall in the room. What is the MINIMUM room size required?
On a survey of one of your client's buildings, you discover that one of the TRs, housing a considerable quantity of switching equipment, is at 25 degrees C (77 degrees F) with a relative humidity of 59 percent. This is considered to be:
You are working on the design of a new, large ER/TR that will contain many racks and data cabinets including a large UPS system. Your recommendation to the architect for room access from inside the building is:
You have the responsibility of designing a railroad track crossing for an outside plant OSP cable. There are three separate railroad tracks to be crossed. The measurement between the center of the two outer tracks is 16 m (52 ft). Using the standard track width of 1435 mm (4 ft 8.5 in), what is the length of the rigid steel conduit required to facilitate the crossing?
You are placing an entrance cable between two buildings connected by a conduit 205.3 m (588 ft) in length. What would be the MAXIMUM length of unlisted OSP cable that could be used before you terminate the cable or transition it to a listed cable?
Active video converters are required for what type of CATV distribution system?
A building has six floors plus a basement. Each floor is 929 sq m (10,000 sq ft) and has approximately 50 CATV outlets respectively. There is a single hardline trunk cable installed from the basement headend passing through the telecommunications room (TR) on each floor. In order to maintain the LEAST signal loss passing through each telecommunications room (TR) to the next telecommunications room (TR), what device should you specify for use within each telecommunications room (TR)?
The headend has several modulators assigning frequencies for distribution to the CATV network. What distribution device should you use immediately at the headend to distribute the modulator's output signals to CATV system?
Which of the following is used to create an electronic signal that can be sent to the central nurse call equipment?
You are renovating telecommunication rooms that support an acute care facility that has 10,000 sq ft floors. The facility will be adding 15,000 sq ft to each of the floors. What is the MINIMUM additional floor space that you will need to expand the TRs to support the new floor space?
