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
• Spanning Tree (RSTP)
• DHCP relay option 82
Security
• IP address anti-spoofing
• MAC address anti-spoofing
• MAC filtering
• DHCP incoming message rate control • Broadcast storm control
• L2/L3/L4 filtering
• MAC flooding prevention
• 802.1x authentication
• AAA server and RADIUS client
Wire-speed architecture The wire-speed architecture enables the bottleneck-free provisioning of high-bandwidth services, such as IPTV or
VoD. This assures QoS by avoiding transmission delay and delivering the appropriate performance in the end-to-end
system.
