Alcatel-Lucent 7705 Service Aggregation Router

The Alcatel-Lucent 7705 Service Aggregation Router (SAR) delivers industry-leading IP/MPLS and pseudowire capabilities in compact platforms with the ability to reliably groom and aggregate multiple media, service and transport protocols onto an economical packet transport infrastructure. The Alcatel-Lucent 7705 SAR is optimized for multiservice adaptation, aggregation and routing, especially onto a modern Ethernet and IP/MPLS infrastructure. Leveraging the powerful Service Router Operating System (SR OS) and 5620 Service Aware Manager (SAM), it is available in compact, low power consumption platforms delivering highly available services over resilient and flexible network topologies. The 7705 SAR is well suited to the aggregation and backhaul of 2G, 3G and LTE mobile traffic — providing cost-effective scaling and the transformation to IP/MPLS networking. Business Services modernization is supported in the transition from legacy to consolidated, packet based operation. Hugely reduced equipment footprints are achievable with reduced energy costs. Enterprise and Vertical organizations can deploy with confidence, achieving reliable and resilient support of legacy and advanced services.

Industry-leading scalability and density is provided in the 7705 SAR-8, a two rack unit (2 RU) version of the 7705 SAR that supports up to 96 T1/E1 Any Service, Any Port (ASAP) ports. The platform can be optionally configured with a redundant control and switch 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-8 has a compact, modular architecture, constructed to allow flexible use of line adapter cards so operators can optimize the configuration to meet the specific requirements of a site. With the modular architecture comes additional resilience and flexibility. The solution can optionally support 1+1 fully redundant CSMs. This industry-leading, independently validated High Availability feature has been inherited from the Service Router product line and is a strong contributor to overall network uptime. Each of the six adapter card slots in the 7705 SAR-8 chassis can be used for any adapter card type, removing the burden of complex pre-engineering and future scenario planning.

The five supported adapter card types are: a 4-port OC-3/STM-1 clear channel card, a 2 port OC-3/STM-1 channelized card, a 16-port ASAP T1/E1 adapter card, an 8-port Ethernet adapter card and a 12 port Serial Data Interface(SDI) card. The 4-port OC-3/STM-1 clear channel card supports ATM and Packet over SONET/SDH (POS) in clear channel mode with ports configurable for SONET or SDH operation. The 2-port OC-3/STM-1 channelized card supports ATM, inverse multiplexing over ATM (IMA) and ML-PPP with ports configurable for SONET or SDH operation. The ASAP adapter card supports ATM, inverse multiplexing over ATM (IMA), TDM and multiclass MLPPP. The Ethernet adapter card has six ports of auto-sensing 10/100 Base-TX ports plus two further ports supporting 10/100/1000 Ethernet with small form factor pluggable (SFP) optics. The 12-port SDI card can be configured for RS232 or V.35 operation. Each slot is connected to the switching fabric on the CSM using a 1 Gb/s link to host existing and future interface types.

The 7705 SAR-F is a fixed configuration version of the Service Aggregation Router. The 7705 SAR-F is packaged in a one rack unit (1 RU) high form factor that supports up to 16 T1/E1 any service any port (ASAP) ports. The ASAP ports can be configured to support ATM, inverse multiplexing over ATM (IMA), TDM and MLPPP. Six 10/100 Base-T auto-sensing Ethernet ports are provided, plus two further ports supporting 10/100/1000 Base TX with small form factor pluggable optics (SFPs).

For both chassis configurations, network uplink connectivity options are: Ethernet, Fast Ethernet (FE), Gigabit Ethernet (GigE), n × T1/ E1 multi-link point-to-point protocol (MLPPP) or n × T1/E1 ATM IMA. Integrated DS3 point-to-point trunking is supported via a small form factor pluggable (SFP) device.
