RCDD (RCDD): Mastering Telecommunications Standards 5

Question 1

What ANSI/TIA standard specifies grounding and bonding requirements for telecommunications in commercial buildings?

Accepted Answer

ANSI/TIA-607

Answer

ANSI/TIA-607 specifies the grounding and bonding requirements for telecommunications infrastructure in commercial buildings.

Question 2

According to TIA-942, which area of a data center houses the main distribution frames and core network equipment?

Accepted Answer

Main Distribution Area (MDA)

Answer

The Main Distribution Area (MDA) in TIA-942 houses the core network equipment and main cross-connects for the data center.

Question 3

In ANSI/TIA-568, what is the Permanent Link test configuration used to verify?

Accepted Answer

The fixed installed cabling from outlet to patch panel excluding patch cords

Answer

The Permanent Link tests the fixed installed cabling from the work area outlet to the patch panel, excluding equipment and patch cords.

Question 4

Which parameter, defined in TIA-568, measures the sum of power from all disturbing pairs affecting a single pair at the near end?

Accepted Answer

PSNEXT

Answer

PSNEXT (Power Sum Near-End Crosstalk) measures the combined crosstalk coupling from all disturbing pairs onto a single pair at the near end.

Question 5

What is the minimum clearance specified by ANSI/TIA-569 between communications cable trays and fluorescent lighting fixtures to avoid electromagnetic interference?

Accepted Answer

130 mm (5 in)

Answer

ANSI/TIA-569 requires a minimum 130 mm (5 in) separation between telecommunications cable trays and fluorescent lighting fixtures to minimize EMI.
