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.
