The Evolution of DSL Deployment
1
High speed Internet access is the
foundation upon which broadband
networks are built, but it takes more
than access to attract and retain new
customers. Service providers need
an access management platform that
enables advanced revenue-generating
services for business and residential
customers, protects existing investments,
and provides guaranteed bandwidth.
With its multiple classes of digital
subscriber line (DSL) service, interop-
erability with legacy equipment,
multiple ATM QoS capabilities, and IP
functionality, the Alcatel 7300 ASAM is
the answer for DSL deployment.
With the largest installed base of
DSLAMs in the world, Alcatel designed
the new, low profile Alcatel 7300 ASAM
LP to seamlessly integrate with these
systems and with the 70 million lines
currently being served by Alcatel or
third party digital loop carriers (DLCs).
As DSL proliferation continues in the
central office (CO), service providers
will need to focus on remote deploy-
ment of DSL to ensure continued
success. The Alcatel 7300 ASAM LP
accomplishes this by integrating into
the existing network infrastructure.
Service providers can mix the Alcatel
7300 ASAM LP shelves with legacy
shelves in the field to create a single
system that delivers enhanced function-
ality while preserving past investments
in voice infrastructure. Beyond hardware
interconnectivity and software consis-
tency, the systems also share a single
management system, simplifying the
integration of the Alcatel 7300 ASAM
LP into the DSL network.
Feature SummaryThe Alcatel 7300 ASAM LP helps to
leverage existing infrastructure by
installing easily into existing DLC
cabinets. It is a proven adjunct solution
as a DLC overlay. This highly deployable
platform offers a port density of up
to 24 lines per card. The Alcatel 7300
ASAM LP scales to 5,000 lines per
network interface. Its power consump-
tion of 1.6 watts per line is the lowest
in the market.
The Alcatel 7300 ASAM LP features a
wide variety of interfaces. They include
DSL interfaces (asymmetric DSL (ADSL),
G.lite, G.shdsl), network interfaces
(DS3, OC-3), and subtending interfaces
(DS1, inverse multiplexing over ATM
(IMA), DS3, OC-3).

The advanced features of the Alcatel
7300 ASAM LP include support of vir-
tual circuit (VC) aggregation, switched
virtual circuits (SVCs), IP multicast,
virtual private networks (VPNs),
multiprotocol label switching (MPLS),
and multiple levels of ATM QoS,
including unspecified bit rate (UBR),
constant bit rate (CBR), variable bit
rate VBR), and guaranteed frame
rate (GFR).
The Alcatel 7300 ASAM LP is a true
carrier class device, offering integrated
test access and redundancy. It can oper-
ate in extreme temperatures and is listed
with Underwriters Laboratories (UL).
ArchitectureThe Alcatel 7300 ASAM family can
contain as few as 12 DSL lines, or as
many as 2,592 lines sharing a common
network interface. This number can
go up to 10,000 by subtending shelves.
An Alcatel 7300 ASAM can manage the
Alcatel 1000 Remote Access Multiplexer
(RAM), the Alcatel 7300 DSL Remote
Access Platform (RAM), the Alcatel
1000 ASAM Mini-Remote Access
Multiplexer (M-RAM), and the Alcatel
7300 ASAM LP. This extends the reach
and capabilities of DSL to remote
customers and increases the number of
customers served by a single network
interface. A broad range of network and
subtending interfaces are available.
The Alcatel 7300 ASAM LP, designed
primarily for remote deployment,
provides service for 144 lines per shelf
and 288 lines per adjunct cabinet. One
rack can contain 432 lines for central
office or controlled environment vault
deployment as well. With the ability
to provide ADSL, full rate SHDSL,
IP-multicast, VPN, and aggregation,
100 percent DSL penetration is possible
with a complete service portfolio. The
full range of QoS for delivery of business
services, video, and voice over DSL
(VoDSL) make the Alcatel 7300 ASAM
LP a full service remote solution.
Including other DLCs into the adjunct
local connection saves on facilities
costs, and the standards-based architec-
ture of the ASAM family helps achieve
service ubiquity with the existing DSL
network. The integration of the Alcatel
7300 ASAM LP into existing ASAM
networks requires no new methods,
procedures, or equipment practices.
Expanding the Power of the Access Platform
3
The IP Services Module (ISM) is the
first of this line of products to offer IP
and broadband remote access server
(BRAS) functions and features, like
IP multicast, VC aggregation, and local
Ethernet connectivity in the access
network. The ISM is a two-slot line
termination card that slides into the
front of the Alcatel 7300 ASAM.
The ISM enables video multicast serv-
ices with Internet group management
protocol (IGMP) at the edge. This signif-
icantly increases delivery capabilities
and reduces network congestion. The
growth of broadband services like video
is driving the requirement for more
intelligent IP-based devices that provide
differentiated access services.
As more ADSL technology is deployed,
scalability and efficiency become critical
issues. The ISM is a multiservice access
concentrator platform based on the
Alcatel 7404 Broadband Access Server
(BAS). It provides termination of ATM
encapsulation, session management,
and IP layer filtering and forwarding.
The adapter optimizes provisioning
and network management with VC
aggregation while it opens Ethernet
connectivity to the Alcatel 7300 ASAM
LP, providing open access to both
ATM and IP networks for distributed
content servers.

TroubleshootingDSL deployments can require in-depth
troubleshooting. If subscriber loops are
too long, they may be unsuitable for
DSL service. Load coils, bridge taps, or
wideband noise on the line can cripple
DSL service performance. Diagnosing
such problems may require costly truck
deployments and the expertise of
senior technicians. This may result in
delays of several weeks, dissatisfied
customers, lost revenues, and higher
operational costs.
To overcome these issues, service
providers need a streamlined deploy-
ment process. Alcatel’s integrated test
access capabilities provide visibility
of the entire network before lines
are put in service. This allows line
qualification without false positive
or false negative results.
Better tools can help providers qualify,
test, and troubleshoot DSL services
more efficiently. Tools that can be used
proactively help service providers to
identify potential customers and eligible
services and to pinpoint problems early.
As a result, installations proceed
smoothly and quickly, with minimal
deployment delays and lower
operating costs.
Unsurpassed QoS The Alcatel 7300 ASAM LP supports
permanent virtual circuit (PVC)
connections provisioned by network
operators, and SVC connections set up
and managed by the user application
when needed. Users gain greater flexi-
bility in accessing multiple applications
offered by various content providers.
Network operators gain traffic capacity
and simplified provisioning.
The Alcatel 7300 ASAM LP is built
around an ATM architecture that
supports a variety of ATM service
classes including CBR, UBR and UBR+,
real time and non real-time variable bit
rate (rt-VBR and nrt-VBR), and GFR.
This gives service providers exceptional
flexibility in service offerings. These
offerings can range from low cost, low
priority residential services to premium
business access with large bandwidth
requirements, such as LAN-to-LAN,
VPNs, streaming video, and audio.
All of these service offerings have
guaranteed performance.
Reach All PotentialSubscribersIn a fast growing mass market like DSL,
the first provider to the customer wins.
The Alcatel 7300 ASAM and Alcatel 7300
ASAM LP deliver maximum scalability
for small to large system deployments
that allow service providers to reach
more of their potential DSL customers,
whether they are served by a CO or
by remote facilities. The operator can
quickly achieve broad geographic
coverage with small systems, and
extend the capacity of these systems at
the pace of growing customer demand.
The system is temperature hardened so
it can be reliably deployed in extreme
temperature environments or in office
buildings. These capabilities, along
with the multiple DSL types, mean
that service providers can service more
customers and have more flexibility
to meet their demands.
