The 7705 Service Aggregation Router (SAR) is optimized for multiservice adaptation, aggregation, and routing, especially onto a modern, economical 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. Strong Quality of Service (QoS) capabilities ensure service-level awareness and the management of multiple traffic streams. The 7705 SAR is well suited to the aggregation, backhaul, and routing 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. The U.S. Federal Government can deploy with confidence, achieving reliable and resilient support of legacy and advanced services.
7705 SAR-M
The 7705 SAR-M is a series of high-performance, one rack unit (1 RU), high form factor Service Aggregation Routers that are available in four different configurations. All four variants of the SAR-M support four 10/100/1000 Base-TX with small form factor pluggable optics (SFP) plus three 10/100/1000 Base-T auto-sensing Ethernet ports. The variable capabilities of the four variants include:
- Fan cooled with a module slot
- Fan cooled with a module slot, plus 16 T1/E1s any-service-any-port (ASAP) ports
- Passively cooled with no module slot
- Passively cooled with no module slot, plus 16 T1/E1s any service any port (ASAP) ports
The expansion module slot, provided on two of the 7705 SAR-M variants, can support one of the following plug-in modules:
- An integrated GPON ONT
- A DSL Combo Module (DCM) supporting four pairs of G.SHDSL, plus two pairs of ADSL2/2+/ VDSL2 with ATM/PTM bonding
- An xDSL module supporting up to eight pairs of PTM bonding over ADSL2/2+/VDSL2
- An integrated CWDM Optical Add-Drop Mux (OADM) module
The T1/E1 ASAP ports, provided on two of the 7705 SAR-M variants, can be configured to support ATM, ATM IMA, TDM and MLPPP.
Network uplink connectivity options are: Ethernet, Fast Ethernet (FE), Gigabit Ethernet (GigE), n × T1/ E1 MLPPP or n × T1/E1 ATM IMA, GPON, multi-pair bonded DSL or CWDM interworking via colored SFPs. Integrated DS3 point-to-point trunking is supported using a SFP device.
7705 SAR-8
The 7705 SAR-8 is a 2 RU version of the 7705 SAR with industry leading access density. The platform can be optionally configured with a redundant control and switch module and uplinks. The 7705 SAR-8 has eight slots: two slots are allocated for control and switch modules (CSMs), with the remaining six slots available for user traffic adapter cards. The 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 platform 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. Network uplink connectivity options are: Ethernet, FE, GigE, n × T1/ E1 MLPPP or n × T1/E1 ATM IMA. Integrated DS3 point-to-point trunking is supported using the 4-port DS3 adapter card. OC-3/STM-1 trunking is supported using packet over SONET/ SDH (POS) on the 4-port OC-3/STM-1 clear channel adapter card.
7705 SAR-18
The 7705 SAR-18 is a 10 RU version of the 7705 SAR with industry leading scalability. The platform can be optionally configured with a redundant control and switch module and uplinks. The 7705 SAR-18 has 18 slots: two slots are allocated for control and switch modules (CSMs), with the remaining 16 slots available for user traffic adapter cards. Twelve of the adapter card slots have full duplex 2.5 Gb/s connectivity to the switching fabric, while the remaining four slots have full duplex 10 Gb/s connectivity.
The platform can optionally support 1+1 fully redundant CSMs for high availability. The twelve 2.5 Gb/s adapter card slots support the same adapter cards as the 7705 SAR-8. Network connectivity options include: Ethernet, FE, GigE, n × T1/ E1 MLPPP or n × T1/E1 ATM IMA. Integrated DS3 point-to-point trunking is supported using the 4-port DS3 adapter card. OC-3/STM-1 trunking is supported using POS on the 4-port OC-3/STM-1 clear channel adapter card.
