The Alcatel-Lucent 7705 Service Aggregation Router delivers industry-leading IP/MPLS and pseudo-wire 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 7705 SAR is extremely well suited to the transport needs of the evolving mobile RAN (radio access network). 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 in wireline aggregation and routing, for example in a T1/E1 private line multiplexing environment. The 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 7705 SAR brings a powerful, service-oriented capability to the RAN, but in a form factor and price point that is particularly appropriate for cell sites and hub locations. With end-to-end service creation under the 5620 management portfolio, the 7705 SAR greatly enhances the IP/MPLS RAN transport solution from Alcatel- Lucent. Industry-leading scalability and density is provided in the 8 slot, 2 RU version, supporting up to 96 T1/E1 ASAP ports. On the network uplink side, media connectivity options are: Ethernet, Fast Ethernet, Gigabit Ethernet, or n x T1/E1 multi-link point-to-point protocol. The platform can be optionally configured with a redundant core control module and uplinks. The 7705 SAR-8 has eight slots, two are allocated for control modules, with the remaining six being available for user traffic interface modules. The 7705 SAR has a compact modular architecture, constructed to allow flexible use of line cards for optimisation based upon per-site requirements. With the modular architecture comes additional resilience and flexibility. The solution can optionally support 1+1 fully redundant control cards. Each line card has dual paths to the active and standby control cards. Each slot can be used for any line card, removing the burden of complex pre-engineering and future scenario planning. The two line cards supported in R1.0 are a 16 port ASAP (any service, any port) T1/E1 card and an 8 port Ethernet card. The ASAP card supports ATM, IMA, TDM and MLPPP to allow equipment to be daisy chained. The Ethernet card has 6 ports of auto-sensing 10/100 Base-T ports plus 2 further ports supporting 10/100/1000 Base TX with small form factor pluggable optics (SFPs). Each slot is connected to the switching fabric via a 1 Gb/s link to host existing and future interface types.
