The Alcatel-Lucent 7705 Service Aggregation Router (SAR) delivers industry-leading IP/MPLS and pseudowire  
capabilities in a compact platform that has the ability to groom and aggregate multiple media, service and  
transport protocols onto a normalized, economical packet transport infrastructure.  
The Alcatel-Lucent 7705 SAR is extrem-  
ely well suited to the transport needs of  
the evolving mobile radio access network  
(RAN). The platform delivers strong  
convergence capabilities in the mobile  
RAN with native service processing of  
2G, 3G and 4G traffic. In addition, the  
platform can provide a powerful solution  
for wireline aggregation and routing in  
carrier and enterprise applications. For  
example, the Alcatel-Lucent 7705 SAR  
can be deployed in a T1/E1 private  
line multiplexing environment.  
Any Service, Any Port (ASAP) ports. On  
the network uplink side, media connec-  
tivity options are: Ethernet, Fast Ethernet  
(FE), Gigabit Ethernet (GE), or n xT1/E1  
Multi-Link Point-to-Point Protocol  
(MLPPP). The platform can be option-  
ally configured with a redundant core  
control module and uplinks. The  
Alcatel-Lucent 7705 SAR-8 has eight  
slots; two are allocated for control  
and switch modules (CSMs), with the  
remaining six being available for user  
traffic adapter cards. The Alcatel-  
Lucent 7705 SAR has a compact modular  
architecture, constructed to allow  
flexible use of line adapter cards so  
operators can optimize the configura-  
tion to meet the specific requirements  
of a site.  
The Alcatel-Lucent 7705 SAR owes  
much of its development heritage  
to the Alcatel-Lucent Service Router  
(SR) product line. Sharing much of  
the market-leading feature set of that  
product, the Alcatel-Lucent 7705 SAR  
brings a powerful, service-oriented  
capability to the RAN, but in a form  
factor and at a price point that are  
particularly appropriate for cell sites  
and hub locations. With end-to-end  
service management under the  
With the modular architecture comes  
additional resilience and flexibility.  
The solution can optionally support  
1+1 fully redundant CSMs. Each adapter  
card has dual paths to the active and  
standby CSMs. Each of the six adapter  
card slots can be used for any adapter  
card type, removing the burden of  
complex pre-engineering and future  
scenario planning. The two adapter  
card types supported in Release 1.0 are  
a 16-port ASAP T1/E1 adapter card and  
an 8-port Ethernet adapter card.  
Alcatel-Lucent 5620 management  
portfolio, the Alcatel-Lucent 7705 SAR  
greatly augments the IP/MPLS RAN  
transport solution from Alcatel-Lucent.  
Industry-leading scalability and density  
is provided in the 8-slot, two rack unit  
(RU) version that supports up to 96 T1/E1  
 
The Alcatel-Lucent 7705 SAR utilizes  
extensive traffic management policies  
to ensure fairness with detailed  
classification and hierarchical schedul-  
ing including minimum/maximum,  
profiled, round robin and strict priority  
scheduling and multi-tier policing to  
differentiate and prioritize individual  
services and flows.  
The Alcatel-Lucent 7705 SAR supports  
external reference timing, line timing  
and adaptive timing in Release 1.0.  
The adaptive timing is fully capable of  
offering end-to-end synchronization.  
In addition, the Alcatel-Lucent 7705  
SAR is completely hardware-ready to  
support IEEE1588v2. This IEEE standard  
defines a method to minimize the  
effects of delay and delay variation  
(jitter). This is accomplished by a combi-  
nation of built-in architectural features  
and also powerful QoS mechanisms to  
minimize the delay experienced by  
synchronization traffic. This is a corner-  
stone of the design of the Alcatel-Lucent  
7705 SAR. A built-in Stratum-3 clock is  
available in the control and switch module  
to assist in synchronization maintenance.  
Benefits  
• Transition from PDH-based  
connectivity to Ethernet-based  
can greatly reduce recurring  
operating expenditures such  
as line lease costs.  
• Advanced resiliency features lead  
to improved network uptime, which  
can positively impact customer retention  
and allow critical services to be  
offered for increased revenue.  
Operations, administration  
and maintenance  
In order to ensure continuity of  
services, the Alcatel-Lucent 7705 SAR  
has a full set of operations, adminis-  
tration and maintenance (OAM)  
features including:  
• Rapid fault detection and powerful  
commissioning and troubleshooting  
tools can improve productivity of  
operations staff and reduce network  
downtime.  
• LSP ping  
• Multiprotocol and convergence  
capabilities (with flexible and  
• LSP traceroute  
granular QoS) reduce equipment  
instances needed to carry multiple  
fixed and mobile traffic streams.  
• Service distribution path (SDP) ping  
Features  
¬ Verifies, for example, tunnel  
connectivity and round trip delay  
• Cost-effective migration from E1/  
T1-based backhaul to packet-based  
transport, leveraging Ethernet ser-  
vices over a wide range of first mile  
media.  
• Modular, flexible architecture  
alleviates the burden of complex  
pre-engineering and future  
scenario planning.  
• Virtual circuit connectivity  
verification (VCCV)  
¬ Verifies, for example, service level  
existence and round trip time  
¬ Extends OAM to pseudowire  
services  
• Resiliency and redundancy including:  
one-for-one hitless control and switch  
module failover, synchronization re-  
dundancy, network uplink resiliency  
and redundancy of power feeds.  
• Service Assurance Agent (SAA)  
¬ Runs in background, periodically  
collecting network “health” infor-  
mation from OAM mechanisms such  
as VCCV and monitoring for prob-  
lems such as SLA transgressions.  
• Powerful, service-aware OAM  
capabilities complemented by the  
Alcatel-Lucent 5620 management  
portfolio for GUI-based network  
and element configuration, pro-  
visioning, fault and performance  
management.  
These features, when under the  
control of the Alcatel-Lucent 5620  
management portfolio, ensure rapid  
fault detection as well as efficient  
troubleshooting. In particular, SLAs  
can be monitored, and transgressions  
detected and reported via the SAA.  
• Dense adaptation of multiple con-  
verged services onto an economical  
packet infrastructure.  
• Extends service routing IP/MPLS  
capabilities to the cell site, hubs  
and network edge in a compact  
form factor.  
Synchronization  
Cell sites rely on the backhaul network  
to provide synchronous interfaces for  
the proper delivery of data. In addition,  
cell sites may rely on the network  
interfaces as stable references with  
which to derive radio frequencies (RFs)  
and in order to ensure reliable subscriber  
handover between cell towers.  
• Dynamic tunnel signaling for scaling,  
ease of establishment and resiliency.
