2 Alcatel-Lucent Service Router SONET/SDH MDAs
Alcatel-Lucent 7750 SR and facilitates
the reuse of selected MDAs to mini -
mize CAPEX. Designed for smaller points
of presence (PoPs), hub sites and enter -
prise offices, the Alcatel-Lucent 7710 SR
family gives service providers, cable
MSOs and enter prise customers a com -
petitive edge by allowing them to
right-size their infrastructure buildouts
with a fully featured router in a smaller
footprint. The Alcatel-Lucent 7710 SR
family is also an ideal solution for enter -
prise customers in key vertical markets,
such as government, utilities and trans -
portation, that need to pro vide more
secure, reli able and manage able data
services for their end users. Available in
two modular chassis sizes that support
up to 4 or 12 interface cards, the Alcatel-
Lucent 7710 SR offers a wide range of
interface options using compact media
adapters (CMAs) and selected MDAs
with unmatched service performance.
All products in the Alcatel-Lucent SR
family are based on the carrier-grade,
production-hardened Alcatel-Lucent
Service Router Operating System
(SR OS), which is designed to deliver
residential, business and mobile services
with optimal cost-effectiveness.
Alcatel-Lucent SR SONET/
SDH MDAs
The SONET/SDH MDAs provide the
critical high-speed, high-density service
interfaces required for a new wave
of next-generation IP-based services.
Table 1 lists the SONET/SDH MDAs that
are supported by the Alcatel-Lucent
SR family.
The three available chassis of the Alcatel-
Lucent 7750 SR — SR-12, SR-7 and SR-1
— support ten, five and one I/O module
(IOM) respectively. The I/O slot capacity
for all chassis is 20 Gb/s (full duplex),
with scaling to 40 Gb/s (full duplex) for
the Alcatel-Lucent SR-12 and SR-7. Each
IOM accepts two MDAs.
The Alcatel-Lucent 7710 SR supports
the 8-port OC-3c/STM-1c MDA and the
2-port OC-48c/ STM-16c MDA, as listed
in Table 1. Each MDA requires an MDA
carrier module (MCM), which is a small
hot-pluggable module that fits across
two standard Alcatel-Lucent 7710 SR
I/O positions. Each MCM accepts one
MDA as a daughter module. The Alcatel-
Lucent 7710 SR-c4 supports up to two
MDAs while the 7710 SR-c12 supports
up to six MDAs, with a throughput rate
of up to 4.4 Gb/s per MDA (full duplex)
to each control and forwarding
module (CFM).
SONET/SDH MDAs provide:
• Interface speeds from OC-3/ STM-1c
to OC-192/STM-64c
• High interface density — up to 320
OC-3c/STM-1c or OC-12c/ STM-4c
ports per Alcatel-Lucent 7750 SR-12
chassis
• Multiple-rate OC-3c/OC-12, STM-1c/
STM-4c, and software selectable on
a per-port basis
• Multimode and single-mode media
types
• SFP optics for added flexibility and
optimal slot utilization
• Optical link budget, supporting
dis tances up to 85 kilometers
(52.8 miles)
• In-service removal and insertion
FEATURES
The SONET/SDH MDAs support the full
scope of the Alcatel-Lucent SR OS
feature set, including:
• Flexible, high-performance services:
¬ virtual private LAN service (VPLS)
¬ BGP/MPLS VPN (based on RFC
4364) and IP-VPN services
¬ dedicated Internet access services
¬ Ethernet, frame relay and ATM
virtual private wire (VPWS) services
• High-performance IP and MPLS
tunneling
• Rich MPLS multiservice transit
capabilities
• Flexible Fast Path technology,
providing up to 10 Gb/s packet
processing with service headroom
• Tens of thousands of configurable
ingress/egress access control lists
(ACLs)
• Scalable BGP, OSPF and IS-IS routing
with traffic-engineering extensions
• Per-service hierarchical quality of
service (H-QoS), with up to 8,000
ingress and egress queues per MDA
and 200-ms buffering up to 10 Gb/s
• Granular, per-service accounting
and billing
• Extensive operations, administration
and maintenance (OAM) tools for
service-aware troubleshooting and
faster service activation
