Answers.
Which piece of equipment in the VoIP phone system routes a call to the public switched telephone
network (PTSN) when the receiving location is from outside the PacketCable managed IP network?
Gateway
What are the three sub-network interfaces managed by PacketCable?
Hybrid fiber/coax (HFC), managed IP, and public switched telephone network (PSTN).
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.
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.
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?
