The
DSL versions that are available in my
area for a home user is ADSL all
other form such as RADSL and HDSL were not. The reason for this is
that my place of residence is to far from the nearest repeater or hub. These
are being updated so that business’s in the area can have the higher end lines.
These are referring to VDSL and SDSL. They will be implementing more
hubs repeaters as well as dropping fiberoptic lines to increase the bandwith.
They are also adding a new form of DSL
to the area which is referred to as a CDSL
or Consumer Digital Subscriber Line. South Western Bell and COVAD are
the two DSL providers in my area.
Their prices were quite similar but the services had some important differences.
(See DSL 1-1) Such as it would be cheaper if is did a CSI or Customer Self-Install for SW Bell but if I did the same for COVAD it would cost
the same. The COVAD has some things I
prefer to SW Bell. COVAD does not have a contract unlike SW Bell who requires
it. I prefer not to have a contract
with a company because if I decide to
move out side the area then I still have to pay for DSL with out receiving it. But SW Bell has Dial up, Multiple IP’s
and Newsgroups where COVAD does not.
(DSL 1-1)
As well COVAD has 50MB of web storage compared to SW
Bells 3 MB web pages. The final decisions comes down to one thing cost.
Southwestern Bell’s grand total would be $250.94 and COVADS would be
$564.00(After rebate from the IPS, MegaPath). This is for the first month of
service.

I chose the CISCO 7505 from the 7000 series of
CISCO routers. This routers comes equipped with five processor slots. Four of which are interface processor slot
and one RSP or Route Switch Processor. (See CISCO 1-1) The Cisco 7505 supports a multi range of protocols
such as virtual routing and bridging over any type of media.
(CISCO 1-1 7505 Router Backpannel)
The Cisco 7505 uses a virtual LAN technology to
connect the networks together. It use’s interface processors to connect from
the 7505 CyBus to the external networks. The CyBus in Cisco’s 7505 is a physical connection between the RSP and transfers information up to
1.067 GBS. The interface processors
plug into slots 0-3 and the others are for RSP1
and RSP2. (See CISCO 1-2) The slots are have special toothing so that you can
not put a RSP into a interface processors spot, and vice a versa.

The Catalyst 5509 Switch (See CISCO 1-4) has nine
slots provides switching, local and remote management, and multiple uplink
interfaces. Slot 2 acts as a back up for slot 1. If a redundant Supervisor
engine is not need then the slots 2 – 9 are use for switching modules. The Cisco
Catalyst 5509 has a 3.6 Gbps media independent switching system. This provides
the connections between supervisor engines, switching modules and power
supplies. The 3.6 Gbs is accessible from all nine slots and supports Ethernet ,
Fast Ethernet, Gigabit Ethernet, FDDI/CDDI, ATM LANE, ATM dual PHY DS3, RSM
and RSM/VIP2 modules.

Cisco’s Virtual Private Networks or VPN’s work a lot of the same way as 3coms and others. They replace existing private networks that use leased-line or Frame Relay/ATM networks. You can use the Cisco 800 or 900 series for small or home office VPN’s. For lager Corporations or business’s there is the Cisco 2600, the Cisco VPN 3000 Concentrator Series, and the Cisco 3600 Series .
Glossary & Citation
All Definitions my not be in Report But are Pertinent
ADSL Lite
A lower data rate version of Asymmetric Digital
Subscriber Line (ADSL).
Broadband
A term for high-speed, high-capacity Internet and data
connections.
CAP
Carrier-less Amplitude/Phase (CAP) modulation; incoming
data modulates a single carrier that is then transmitted down a telephone line.
The carrier itself is suppressed before transmission (it contains no
information, and can be reconstructed at the receiver), hence the adjective
"carrier-less." CAP and DMT are two modulation systems currently on
the market for ADSL.
CDSL
Consumer Digital Subscriber Line (CDSL) is a proprietary
technology trademarked by Rockwell International.
CSI
Customer Self-Install; an option the end-user has to
install their DSL service themselves (and not incur any technician installation
charges). With the documentation provided, the customer will install their DSL
modem and Network Interface Card (NIC) to the computer, which will enable the
DSL connection.
DMT
Discrete Multi-Tone (DMT) multi-carrier modulation uses
256 QAM modulation tones simultaneously to create the ADSL signal. DMT is the
basis of ANSI Standard T1.413, and has the support of other world standards
bodies. CAP and DMT are two modulation systems currently on the market for
ADSL.
DSL
Digital Subscriber Line (DSL) provides a dedicated
digital circuit between a residence and a telephone company's central office,
allowing high-speed data transport over existing twisted copper telephone
lines. We currently offer two ADSL (Asymmetric Digital Subscriber Line) product
options to support information transfer rates of 1.5+Mbps downstream and
384Kbps upstream, or 384+Kbps downstream and 128Kbps upstream.

customer's home or business.
POTS splitter
A Plain Old Telephone Service (POTS) splitter, also
known as a low-pass/high-pass filter, separates the voice and data portions of

Private Virtual Circuit (PVC) is a point-to-point
circuit from the customer premise equipment to either their Internet Service
Provider (ISP) or Enterprise Network.
