Alcatel-Lucent 7705 SAR S E R V I C E A G G R E G A T I O N R O U T E R | R E L E A S E 1 . 0 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. 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 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 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 optionally 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 AlcatelLucent 7705 SAR 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. 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. The ASAP adapter card supports ATM, inverse multiplexing over ATM (IMA), TDM and MLPPP. The Ethernet adapter card has six ports of auto-sensing 10/100 Base-T ports plus two further ports supporting 10/100/1000 Base TX with small form factor pluggable (SFPs) optics. Each slot is connected to the switching fabric on the CSM via a 1 Gb/s link to host existing and future interface types. Service aggregation and networking To provide the most efficient transport solution, the Alcatel-Lucent 7705 SAR employs pseudowire encapsulation (PWE3) methods to map services end to end. The use of pseudowires ensures that the key attributes of the service are maintained, while using a costeffective packet environment to aggregate services. The Alcatel-Lucent 7705 SAR supports RFC 5086 — Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation Service over Packet Switched Network (CESoPSN) for the encapsu lation and transport of TDM traffic, for example, 2G TDM services. The use of circuit emulation service (CES) ensures that only the active timeslots are transported, keeping bandwidth usage to a minimum. The Alcatel-Lucent 7705 SAR also supports RFC 4717 — Encapsu lation Methods for Transport of Asynchronous Transfer Mode (ATM) over MPLS Networks (also known as draft-ietf-pwe3-atm-encap). The Alcatel-Lucent 7705 SAR supports N:1 cell mode for transport of ATM-based services. Multiple access ATM ports are bundled together to attain higher speeds using IMA. The IMA protocol is terminated on the Alcatel-Lucent 7705 SAR and only the cells containing user data belonging to a virtual circuit/virtual path (VC/VP) structure are transported. In addition, the Alcatel-Lucent 7705 SAR supports RFC 4448 — Encapsu lation Methods for Transport of Ethernet over MPLS Networks, which specifies how Ethernet pseudowires can be used to transport Ethernet traffic across the packet network. To offer greater scalability, all the traffic out of an Ethernet port can be carried over a single Ethernet pseudowire or, alternatively, a pseudowire can be created for each VLAN that is assigned to a different service or end-customer. When dynamic signaling is deployed, the end-to-end pseudowire is established using targeted label distribution protocol (T-LDP) and the MPLS tunnel via LDP. In addition to efficient LDP-based dynamic signaling, static provisioning of both the MPLS tunnel and the pseudowire is also supported. Quality of service and traffic management It is critical to maintain the end-to-end quality of service (QoS) for packet traffic. Not all types of traffic have the same set of requirements. Voice traffic in particular requires low latency and jitter (latency variation) and also low loss, whereas data traffic often has less stringent delay requirements but may be very sensitive to loss, as packet loss can seriously constrain applica tion throughput. To offer the req uired treatment throughout the network, traffic flows with different requirements are identified at the access and marked in-line with the appropriate QoS metrics. Traffic classification and marking is carried out based on the following: Classification (Layer 1/Layer 2/Layer 2.5 and/or Layer 3 header): • Timeslot/port • Ethernet port/VLAN • ATM service category (CBR/rt-VBR/nrt-VBR/UBR) • ATM VC • Ethernet 802.1p/VLAN • IP DSCP/MPLS EXP Marking: • Layer 2 (802.1p) • Layer 2.5 (EXP) both for tunnel and PWE3 • Layer 3 (DiffServ) Figure 1.

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: • LSP ping • LSP traceroute • Service distribution path (SDP) ping ¬ Verifies, for example, tunnel connectivity and round trip delay • Virtual circuit connectivity verification (VCCV) ¬ Verifies, for example, service level existence and round trip time ¬ Extends OAM to pseudowire services • Service Assurance Agent (SAA) ¬ Runs in background, periodically collecting network “health” information from OAM mechanisms such as VCCV and monitoring for problems such as SLA transgressions. 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. 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. 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.
