SOLUTION
Which piece of equipment in a VoIP phone system routes a call to the public
switched telephone network (PSTN) when the receiving location is from outside
the PacketCable managed IP network?
Network interface device (NID).
What are the three sub-network interfaces managed by PacketCable?
Hybrid fiber/coax (HFC), managed IP, and public switched telephone network (PSTN).
Which of the VoIP service tiers bypass the cable operator's direct link to the
public switched telephone network (PSTN) and route packets over the Internet to
another telephone company?
Tier II Secondary VoIP
When a call is made from a phone that is on a managed IP phone system to a
phone that is outside the managed IP phone system, how does the call get routed
to the receiving phone?
The gateway down-converts the digital data to an analog electrical signal format and
routes the call to the public switched telephone network (PSTN).
Because a cable operator will support as many lines as technically possible for a
business customer, what does the installer have to do prior to connecting the
embedded multimedia terminal adapter (EMTA)?
Check the RF signal levels on the cable entering the building.
When a PBX or key system is involved in a business installation, the installer can
set up the embedded multimedia terminal adapters (EMTA) and cable, but what
has to happen before the installer can begin connecting the equipment?
The customer's PBX and key system technician must arrive at the location.
For a business telephone installation, which of the following is the preferred
location for the embedded multimedia terminal adapter (EMTA)?
The main closet.
Which of the following is a process that must be followed during a business order
installation and differs from a residential order process?
Making sure the PBX is tested and is functioning properly.
What is the location where the embedded multimedia terminal adapter (EMTA) is
connected to both the outside and inside wiring?
The main closet or telecommunications closet.
Why is PacketCable VoIP a more efficient way of handling calls?
Most cable operators have built their own IP telephone networks that use Internet
Protocol rules.
Before a business telephone installation is performed in an office building, who
must first approve it?
The building owner or management company.
This organization is responsible for developing the telecommunications
standards that address commercial building cabling for telecom products and
services with wiring standards such as T568A and T568B to ensure consistent
wiring and service delivery.
, The Telecommunications Industry Association (TIA).
When extending wiring into another part of a building becomes necessary, who is
responsible for initiating the service?
The customer.
Who owns and is responsible for the wiring between the small and medium
business (SMB) customer's cross-connect block and the cross-connect block
installed by the cable operator?
The customer.
What is the advantage of using a multiple-clip configuration for distribution
applications in the 66-block?
Several extensions can have a direct (i.e., home-run) connection to the same network
circuit.
What organization is responsible for developing telecommunication standards
that address commercial building cabling for telecom products and services?
Telephone Industry Association / Electronic Industry Association (TIA/EIA).
According to Telecommunications Industry Association/Electronic Industries
Alliance (TIA/EIA) standards, which type of unshielded twisted-pair (UTP) cabling
is recommended for data-grade applications?
Category 5e.
Which configuration enables several telephone extensions to have a direct
(home-run) connection to the same network circuit?
A multiple-clip configuration.
If it is necessary to run cables from one intermediate distribution frame (IDF) to
another, what type of connection block is used?
M66-150.
Grounding and protection are required in two places. One is in the equipment
room or telecommunications closet. Where is the other?
Building entrance.
When a circuit is cross-connected to a customer's equipment or telephones, it is
tagged for identification. Where else are telephone numbers and line positions on
the embedded multimedia terminal adapter (EMTA) noted?
On the orange cover of the 66-block.
Why is the T568A wiring configuration recommended over the T568B wiring
configuration?
The T568A configuration is backward compatible with Universal Services Ordering
Code (USOC) RJ-XX wiring.
Which pins are often not installed in a RJ-11 jack?
Pins 1 and 6.
In a T568A wiring scheme for a four-pair connection, which pair uses white/brown
for tip and brown/white for ring?
Pair 4.
When installing a 66-block, which mounting guidelines should be followed?
A mount support bracket (also called a stand-off bracket) should be installed to help
provide needed clearances.
What is a main distribution frame?
A wiring arrangement that connects outside and internal telephone lines.
