Citius Tech?
Answer:
Broadband’s next wave: CITIUS
The CATV network in India reaches 40 million
homes across rural, urban and semi-urban areas,
delivering an equivalent of 2GHz bandwidth to
every household. The existing CATV network is
predominantly one-way and it is a challenge to
transform it into a two-way, digitized delivery
medium to provide triple-play (voice. video and
data) services.
Midas, the pioneer in developing indigenous
state-of-the-art and cost effective broadband
access solutions now offers CITIUS – a unique
Cable/Wireless Internet Triple Play Unified System
that uses innovative and standards-based
techniques to enable broadband, triple-play
services on the existing overhead CATV cables.
To the service provider, CITIUS (Latin for
Speed) promises the fastest roll-out in the
scramble for providing broadband services, while
to the end user, it assures high speed data access
with toll-quality voice and a range of video and
broadband services making it a comprehensive
triple-play solution.
CITIUS gives you the cutting edge
Using ITU J.83B standards, CITIUS can offer
40Mbps downstream bandwidth per CATV
Channel. For upstream connectivity, the system
utilizes corDECT, Midas’ wireless access platform
to provide 40Mbps bandwidth with ‘always-on’
access.
CITIUS facilitates operators to offer a variety of
bandwidth choices to subscribers. With its flexible
configuration, the system provides highly scalable
bandwidth services and can enable differential
upstream/downstream speeds.
The built-in capability to handle toll-quality
voice makes CITIUS an ideal choice for operators
aiming at offering value added voice services.
Additional investments and the complexity
associated with IP phones and soft-switches can
be avoided, as the voice-ready CITIUS system
allows the use of normal telephones and services
such as G3 fax.
The extraordinary bandwidth handling
capacity of the CITIUS system empowers
operators to extend powerful IP based interactive
services such as private broadcast channels,
video-on-demand, interactive gaming and thin
client computing. Such services can even be
enabled on normal televisions, eliminating the
need of a computer.
The CITIUS system is an extremely
cost-effective solution, with minimal operating
costs and low additional investments, making it
suitable for a variety of operator and service
requirements.
CITIUS is the logical choice with an exciting
bundle of benefits – the capability to provide
high performance, interactive triple-play services
at low investments, offering the first-mover
advantage to service providers in the highly
competitive broadband market.

System Architecture
CITIUS – Functional Description
CITIUS consists of CITUS Interface Unit (CIU), CITUS Base
Station (CBS), CITUS Modem or CITUS Subscriber Distribution
Terminal (SDT).
The CIU incorporates a Wireless Base Station Controller and
ITU J.83B Cable Modulator. The subscriber PC sends the
upstream data on ethernet to the Modem or SDT, which uses the
wireless link to transport the ethernet data to CIU through
CITIUS Base Station. The Base Station Controller receives the
upstream data from subscribers through the CITIUS Base
Stations installed across the service area. The wireless link
between subscriber and CIU uses the Point-to-Point Protocol
(PPP) or a bridged connection, based on the configuration.
The upstream traffic is aggregated and forwarded to the Internet
through the ISP infrastructure while downstream data from the
Internet is routed to the Cable Modulator subsystem of the CIU.
The Cable Modulator converts downstream data into a signal
encapsulated as a TV Channel. The design of the system
allows adequate flexibility to the operator to select a suitable
frequency band across a wide spectrum. The output of the
CIU is combined with other CATV channels in the Operator’s
Combiner, to be transported across the cable network.
The data streams on the cable interface are converted into
Ethernet data by CITIUS Modem or the Subscriber
Distribution Terminal at the customer’s premises and sent to
the Subscriber PC.
CITUS is integrated into the operator’s authentication,
accounting and bandwith control systems, for effective and
transparent management of subscriber services across
multiple access network systems of the operator. CITIUS is
completely transparent to the end-user, providing quick,
easy, trouble-free and ‘always-on’ connectivity to the Internet
and other data services. Other Questions and Answers:
