The embedded multimedia terminal adapter is in which of The EMTA is in the DOCSIS HFC, access network
the three networks described in the packet cable
architecture
What Internet protocol IP connectivity modes are
supported NDOCSIS 3.0 and 3.1.
The first version of DOCSIS was approved as an The ITU
international standard by what organization
What criteria does the DOCSIS certification process Compliance with the DOCSIS standard, and interoperability between suppliers
ensure
Which layer of the OSI reference model are specific to Layers 1- through four physical layer, datalink, Claire, Netwerk, layer and transport
cable networks and are present only between DOCSIS layer or applied between the DOCSIS modem, and the CMTS
modems and not the CMTS
, Broadband digital installer conventional
What communications access technology does the first TDMA
version of the DOCSIS 1.0 used to send data upstream
over the networks RF return path
What requirements were needed for packet cable to QOS controls enhanced security and adaptive equalization in the upstream path
deliver a quality and reliable telephone service over a
DOCSIS access net work
What features were introduced with the 3.1 version of the OFDM and LDPC
DOCSIS 3.1 to increase the downstream and upstream
down to throughput
Which DOCSIS version was the first to provide an option DOCSIS 3.0.
for raising the top frequency of the upstream spectrum
85 MHz in order to create enough bandwidth for
upstream carriers from modems running on previous
DOCSIS versions
Why are the delta throughput rates for both downstream Because the narrower band widths and lower orders of modulations for the return
and upstream and Doxis networks asymmetrical? path carriers cause the DOCSIS downstream and upstream data rates to be
unequal or asymmetrical
Which OSI reference model layers does the M•A•C layer The physical and data link layers
in the Docsis overlap so that the MAC can be used by the
CMTS to differentiate between cable modems
Where DOCSIS modems receive their configuration files, From the CMTS, which interfaces with the operations support system and acts as a
billing system, messages and access control messages proxy or messenger, the transfers messages in Files, between the modems and
from the respective servers
Installing a DOCSIS, modem and router, and a smart Access to the coaxial cable so that it can be routed to the DOCSIS modem and
panel or utility room is simplified by having what items in electrical outlet to power of the DOCSIS modem and router and unshielded
the room twisted paired network cable that is labeled and has connectors installed using
standard wiring configurations
Which version of DOCSIS included the option to increase DOCSIS 3.0.
the top frequency from the upstream to 85 MHz
What device can be installed with a DOCSIS modem to A router with a built in multi Jack ethernet switch
enable Internet access to multiple devices in the
customer premises
