7Alcatel-Lucent 1540 Litespan
Broadband (xDSL) traffic is routed through synchro -
nous transport module 1 (STM-1) optical or E3/DS3
electrical interfaces to the ATM backbone, and
through a GigaEthernet port (10/100/1000Base-T or
optical 100/1000 FX) to the (typically) IP backbone.
This increases your flexibility 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 interfaces (V5 for TDM voice services,
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 completely built and tested. You can also
provision the system from a centralized management
center or a local craft terminal. Moreover, the manage -
ment 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 revenues. 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:
• Starting fiber at the most economical point
• Using standard interfaces
• Interconnecting Ethernet, ATM, public switched
telephone network (PSTN)/ISDN, leased lines,
TDM, etc., in a single node
• Supporting flexible topologies in a single system
• Including open interfaces for multivendor
interworking
• Providing integrated network management
Future-Ready and Safe Investment Evolution to NGN
The Alcatel-Lucent 1540 Litespan is designed to be
NGN ready, letting you smoothly convert from a
multiservice access platform supporting today’s TDM
services to a full access media gateway in NGNs.
Through the simple insertion of a VoIP gateway card,
you can transform the node into an NGN access gateway
that supports VoIP services with minimal future invest -
ment. You can also choose which customers remain
connected to the legacy TDM backbone 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.
