Multiservice capabilities for increased

revenue generation

With the multiservice capabilities of the Alcatel-Lucent

1540 Litespan Family, you will be able to expand your

revenue-generating opportunities. In addition to providing

basic narrowband voice and data services (using POTS,

ISDN, basic access/primary rate access, digital leased

lines), the system delivers broadband Internet access,

data transmission and video applications (such as VoD

or IPTV) capabilities over digital subscriber lines (ADSL,

ADSL2 or ADSL2plus) and global standard high bit rate

DSL (G.SHDSL) to enable quicker business data services

for business end users. Alcatel-Lucent’s 1540 Litespan

represents the perfect triple-play solution for many types

of access network scenarios.

Support of multiple topologies for more

ﬂexible applications

Star, ring, tree, point-to-point and mixed topologies are

all supported.

Taking advantage of the Alcatel-

Lucent 1540 Litespan family

Support of multiple transport options for

easy integration with existing networks

The Alcatel-Lucent 1540 Litespan integrates plesiochro-

nous digital hierarchy (PDH) or SDH transport mecha-

nisms for switching and data networks. An SDH add-drop

multiplexer (ADM) with integrated Ethernet over SDH,

occupies just one board. Asynchronous transfer mode

(ATM) and GigaEthernet transport capabilities are also

in the system. Moreover, trafﬁc can be transported be-

tween Litespan exchange units (EUs) and remote sub-

tendingunits(RUs)throughcopperlines(usingHDSL

or g.SHDSL transport protocols), ﬁber connections or

external leased-line networks.

Broadband (xDSL) trafﬁc is routed through synchronous

transport module 1 (STM-1) optical or E3/DS3 electrical

interfaces to the ATM backbone, and through a Giga-

Ethernet port (10/100/1000Base-T or optical 100/1000 FX)

to the (typically) IP backbone. This increases your ﬂex-

ibility when connecting to the IP data backbone through

Metro Ethernet networks.

Open interfaces for

multivendor compatibility,

competitive pricing and

investment protection

The Alcatel-Lucent 1540 Litespan

family is designed with standard in-

terfaces (V5 for TDM voice services,

SIP Megaco/H.248 for VoIP, and

ATM or Ethernet for xDSL trafﬁc)

to ensure that it functions effectively

in open environments. This open

design lets you build competitive,

customized solutions compatible

with your existing investments and

customers’ needs.

Rapid deployment for faster

revenue generation

With the Alcatel-Lucent 1540

Litespan family, your deployment is

simpliﬁed because the indoor racks

and outdoor cabinet conﬁgurations

are delivered from the factory com-

pletely built and tested. You can

also provision the system from a

centralized management center or

a local craft terminal. Moreover,

the management system is consistent

with established systems, minimizing

the learning curve. In short, all of

these features signiﬁcantly shorten

your time-to-revenue.

Lower CAPEX and OPEX and

increased revenues

Because the Alcatel-Lucent 1540

Litespan family provides so many

services on a single platform, it can

signiﬁcantly affect your overall rev-

enues. Plus, its ﬂexible design ensures

you can easily add new services as

user demand requires them.

Just as important, the Alcatel-Lucent

1540 Litespan signiﬁcantly lowers your

capital expenditure (CAPEX) and

operating expenditure (OPEX) by:

Future-ready and safe invest-

ment evolution to NGN

The Alcatel-Lucent 1540 Litespan

is designed to be NGN ready, letting

you smoothly convert from a multi-

service access platform supporting

today’s TDM services to a full access

media gateway in NGNs. Through

the simple insertion of a VoIP gate

way card, you can transform the

node into an NGN access gateway

that supports VoIP services with

minimal future investment. You can

also choose which customers remain

connected to the legacy TDM back-

bone and which migrate to the new

NGN backbone.

Access networks created with Alcatel-Lucent 1540 Litespan can be easily

upgraded to deliver triple play solutions.

Table 1. Alcatel-Lucent 1540 Litespan features and benefits

FEATURES BENEFITS

POTS card integrates ringing and testing The 32-port POTS board integrates the ringing and testing functionality previously provided by dedicated boards

in the system. Integration frees up more slots for services. Together with the available configuration of four multi-

service line shelves (MLSs) per indoor rack, this increases your system capacity to 2,556 POTS lines in a single rack.

Litespan RUs can be subtended from SDH Litespan hubs through an external transport G.703 link.

GigaEthernet network interface xDSL traffic can be redirected toward the backbone through a GigaEthernet port (1000Base-SX, 1000Base-LX,

1000Base-EX, 1000Base-ZX and 1000Base-TX). As a result, your flexibility is increased when connecting to the

IP data backbone through metro Ethernet networks.

Voice controller and servers hot switchover A more reliable architecture for the system’s narrowband controllers is now available. Your subscribers’ voice

calls are not interrupted in case the controller fails while the spare is taking over.

MultiDSL (ADSL, ADSL2 and ADSL2plus) Using different implementations of ADSL technology, the Alcatel-Lucent 1540 Litespan assures you a best-in-class

operation for broadband services in copper loops.

STM-16 ADM with Integrated Ethernet over SDH Smoothly evolve a traditional TDM-based access network to a next-generation packet network. This significantly

improves the service providers’ business case for migrating their access and aggregation from TDM to packet. The

card enables data-aware usage of SDH transport capacity.

Multiple virtual circuits (VCs) allocated per

end-user

Using the Alcatel-Lucent 1540 ADSL boards, several virtual circuits can be established between the ADSL port and

the end-user router. Each VC is devoted to a broadband service (HSIA, video, VoIP, etc.) assuring that no service can

degrade the quality of any other.

IGMP (V3) proxy and snooping for multicast

transmission of video streaming

The Alcatel-Lucent 1540 Litespan uses the IGMP proxy/snooping protocols, allowing a multicast transmission of

IP and optimizing bandwidth resources while delivering IPTV.

Higher scalability and capacity of VoIP server

card

The VoIP server card (VISC) offers up to 508 active calls. A system can include up to 4 VISCs for serving up to more

than 4,000 subscribers. Media gateway functionality is provided for handling POTS, ISDN BA and ISDN PRA connec-

tions. An integrated announcement server and a multiparty conference system are also incorporated.

New Layer 2 and routing protocols and security

features

The Alcatel-Lucent 1540 Litespan is protected against several types of external attacks such as hijacking sessions,

distributed denial of service (DDOS), as well as food attacks. It incorporates the following protocols and security

features, among others:

Protocols

• VLAN Q-in-Q

• IEEE 802.3ad Ethernet link aggregation

• PPPoA, PPPoE, PPPoE relay

• RIP

• OSPF

As part of Alcatel-Lucent’s comprehensive next-genera-

tion access portfolio, the Alcatel-Lucent 1353 Litespan

Management System (LMS) manages the Alcatel-Lucent

1540 Litespan product family. This robust system provides

network viewing, equipment conﬁguration, service provi-

sioning, alarm collection, remote inventory, testing and

remote software upgrades of Alcatel-Lucent 1540 Litespan

network elements. It also offers subscriber management for

voice services.

For ease of service delivery on the Alcatel-Lucent 1540

Litespan platform, the Alcatel-Lucent 1353 LMS, includes

several management applications:

•Alcatel-Lucent 1353 Distributed Network (DN) – Element

manager for voice and leased-line data services. The

Alcatel-Lucent 1353 DN is based on the Alcatel-Lucent

Management Platform (ALMAP). The use of common

system management functions provides an integrated

telecommunications management network (TMN) archi-

tecture, giving you a common look and feel across

ALMAP-based applications.

•1353 SDH Transport Network (NM) – Element manager

for the optional integrated ADM (for SDH services)

¬ Alcatel-Lucent 1353 Gateway (GW) – Application

layered on the Alcatel-Lucent 1353 DN and Alcatel-

Lucent 1353 SH to interface with third-party

operational support systems (OSSs)

•Alcatel-Lucent 1355 DN – Subscriber manager for voice

services

¬ Alcatel-Lucent 1355 GW – Gateway application

layered on the Alcatel-Lucent 1355 DN to interface

with third-party OSSs

•Alcatel-Lucent 5523 ADSL Work Station (AWS) –

Element manager for xDSL (broadband) services

The Alcatel-Lucent 1353 Litespan Management System

Alcatel-Lucent 1540 Litespan10

The modular Alcatel-Lucent 1353 Litespan Management

System (LMS) incorporates several management modules,

depending on the network topology and system manage-

ment requirements. The capability to run network manage-

ment applications from any server in the system reduces

the number of servers required, lowering your CAPEX.

The internal communications framework makes the

Alcatel-Lucent 1353 LMS independent of some third-party

applications, thereby reducing your software license costs.

And, remote provisioning, upgrading and testing reduces

truck rolls and lowers operating expenditures (OPEX).

Managing for success

Table 2. Key features and benefits of the Alcatel-Lucent 1353 LMS

FEATURE DESCRIPTION

Narrowband and broadband applications in a single server The Alcatel-Lucent 5523 AWS and 1353 DN applications can run on a single server, thus optimiz-

ing hardware investments, which are used to run the Alcatel-Lucent 1353 LMS for managing small

networks.

Alcatel-Lucent 1353 LMS high availability System availability is enhanced through N+1 server redundancy, which keeps the system resilient

by having a stand-by server take control of applications running in the faulty server.

Common integrated desktop in Alcatel-Lucent 1353 LMS Operators can run any network management application from any server in the system. This reduces

the number of servers required to run all applications for the Alcatel-Lucent LMS. The net result is

reduced investment in hardware.

Logical inventory Using the logical inventory, operators can query specific access nodes about the type of subscriber,

as well as the directory number, rack, subrack, and physical ports.

Outband and in-band interfaces for the DCN The outband and in-band interfaces provide any kind of connectivity to the access nodes from the

Alcatel-Lucent LMS, by using either outband or in-band connections — the same connections that

are used for traffic payload.
