1. Overview of the 3P@C 4450E IP-DSLAM
This chapter describes the typical networking models, features and performance indexes of the 3P@C 4400E.
1.1. System Overview
As the heart of Next Generation network architecture, SAGEM 3P@C 4450E and 4048E are high-performance
IP-DSLAM platforms that enable to deliver a wide variety of services such as broadband internet, voice over
packet, LAN to LAN connections, video multicast streaming, leased lines and VPN, on any subscriber line.
Thanks to their flexible, modular and scalable design, SAGEM 3P@C systems can provide all services simply by
the composition of relevant units in the same carrier-class platform.
NG-DSLAM
SAGEM 3P@C supports any combinations of ADSL, ADSL2/2+ or VDSL user interfaces in several types of
high-density configurations : mini-shelf and large shelves.
Thanks to its internal architecture, the SAGEM 3P@C is able to concentrate user streams and switch them to
several network interfaces, managing traffic parameters in order to guarantee QoS requirements. Subtending
interfaces can be used to create star and daisy-chain extensions, offering a high scalability in order to reach
remote users.
A wide variety of Fast Ethernet, Giga Ethernet, Packet over SDH and even ATM uplink interfaces allows the
connection to Next Generation IP and Ethernet networks. Enhanced video services can be delivered over
ADSL2+ or ADSL connections, such as TV broadcast, Video on Demand and Pay Per View, using SAGEM
3P@C multicast and IGMP capabilities. Connecting to ISP network, SAGEM 3P@C can support B-RAS features
such as PPP session processing, tunnelling and termination, user authentication, IP address management and
dynamic routing.
Management
SAGEM IONOS NMS management platform is designed for the provisionning, monitoring and supervision of the
whole SAGEM 3P@C product family. This powerful NMS allows network-wide visibility and provides user-
friendly graphical features. In addition, IONOS NMS enhances operational efficiency with its powerful
client/server architecture.
Scalable range
SAGEM 3P@C is a complete range of access equipment, scaling from small sized configurations to large central
office nodes.
SAGEM 3P@C 4450E is dedicated to high density CO, connecting up to 448 DSL users per subrack, whereas
SAGEM 3P@C 4048E is designed for small CO or remote sites connecting up to 48 ADSL users.
The micro-DSLAM is targeted to specific applications, such as Multi-Tenant Unit (MTU) and remote area.
Thanks to its stackable design, up to 192 users can be connected as the need for broadband connections grows.
The 3P@C 4048E can be installed as a stand alone unit connected to a switched network or as an extension of
3P@C 4450E in subtending mode.
