Description
Media terminal
adapter (MTA)
A network client that provides user terminal (such as a phone set)-
oriented ports and call control unit-oriented network signaling
interfaces. It connects to cable network units through an HFC network.
MTAs are classified into embedded MTAs (EMTAs) and single MTAs
(SMTAs) according to PacketCable.
l
An EMTA integrates CM and MTA functions.
l
An SMTA supports only MTA functionalities.
VoD
A technology that enables users to order any program in a VoD program
library. During program playing, users can perform operations, such as
pause, fast forward, fast rewind, and program locating.
Distributor
A component that distributes signals in a cable TV (CATV) transmission
system. It equally outputs several channels of signals from one channel
of input signals. The common distribution ratios are 1:2, 1:3, 1:4, and
1:6.
Optical Node
Concept
Description
D-CMTS
A device that connects an aggregation network to an HFC network. It
forwards network data, processes protocols, and modulates or
demodulates radio frequency (RF) signals. The D-CMTS provides the
quality of service (QoS) required by CMs and allocates upstream
bandwidths and service resources to the CMs based on CMs' request and
network QoS policy.
Built-in optical
receiver
l
An optical receiver, which performs optical-to-electrical (O/E)
conversion for CATV and upstream backhaul signals.
l
The fiber node does not require an additional optical receiver. The
O/E conversion is performed by the optical receiver built in the
MA5633 and the MA5633 can receive CATV optical signals.
Built-in WDM
l
A device that multiplexes the optical signals with different standard
wavelengths into one channel of multiplexed signals and transmits
the signals over one optical fiber.
l
The WDM in the branch equipment room combines data signals and
CATV signals for signal transmission over one feeder fiber. On the
optical node, the WDM built in the MA5633 separates the two types
of signals from each other.
