VB 5200 Mobile Backhauling Cell-Site Gateway Multi-generation cellular traffic over packet-switched networks (PSNs) and TDM/ATM, using fiber and DSL uplinks • Ultimate cell-site gateway • Multi-standard pseudowire encapsulation for delivery of Ethernet and TDM/ATM traffic over PSNs • Two modular uplink interfaces supporting GbE, SHDSL.bis, ADSL2/2+ and VDSL2-ready • Designed for 2G/3G/LTE and WiMAX • Flexible clocking mechanism with IEEE 1588-2008 and Sync-E The VB 5200 multiservice cell-site gateway is designed to accommodate the rapid expansion in cellular backhaul traffic resulting from the widespread deployment of new mobile broadband services. It simplifies service provisioning and control by enabling simultaneous delivery of GSM, UMTS and next-generation 3GPP/LTE WiMAX traffic over the same transport network. Working opposite aggregation site gateways, VB 5200 minimizes investments and shortens service rollout times by leveraging available ATM, SDH/SONET, and DSL infrastructure to access high-capacity, economical packet-switched transport networks. BROAD RANGE OF INTERFACES A variety of built-in interfaces is available to serve as user or network ports: • 8 or 16 ATM UNI/IMA/TDM E1/T1 user ports • Optional STM1/OC 3c ATM port • 4 UTP/SFP Fast Ethernet ports. In addition, VB 5200 supports up to two interface modules, accommodating two ADSL2+ ports, four SHDSL.bis ports supporting IMA, M-pair or EFM bonding, and a combo GbE port. Depending on the original traffic type, IP traffic (received from IP Node B), ATM or TDM traffic (received via E1/T1) is transmitted over Ethernet, TDM, ATM PWE, EthoATM, PWEoATM or ATM cross-connects. VB 5200 Mobile Backhauling Cell-Site Gateway PSEUDOWIRE CAPABILITIES ADVANCED PSEUDOWIRE QOS EFM BONDING VB 5200 allows up to 128 PW connections to be established over PSN, 32 clock distribution PWs and 2 clock recovery PWs. Required QoS is achieved by employing different prioritization techniques: Rates of up to 22 Mbps can be achieved by aggregating up to four 2wire SHDSL.bis interfaces into a single Ethernet link. This EFM bonding technolgy enables carriers to deliver state-of-the-art Ethernet services while leveraging the existing copper infrastructure and DSLAM deployments. • Layer 2 – outgoing pseudowire packets are assigned with a dedicated VLAN ID according to 802.1q. A priority is defined using 802.1p bits. • MPLS – outgoing pseudowire packets are assigned to a specific MPLS tunnel and a priority is defined using EXP bits. ATMoPSN – Pseudowire connections can be established over PSN according to RFC 4717: • 1-to-1 VC/VP – Each VCC/VPC is mapped into a single pseudowire connection. • N-to-1 VC/VP – Several VCs or VPs can be encapsulated into a single pseudowire connection. • AAL5 SDU – Each VCC is mapped to a single pseudowire connection. TDMoPSN – TDM pseudowire connections can be established over PSN according to IETF RFC 5086 (CESoPSN/ SAToP). SAToP complies with IETF RFC 4553. Ethernet – Ethernet pseudowire encapsulation is used to carry Ethernet/802.3 traffic over an MPLS network. Ethernet PW operation complies with IETF RFC 4448. Following PSN encapsulation formats are supported: • IP –a priority is defined to outgoing pseudowire packets using ToS/DSCP bits ATM SWITCHING AND POLICING Full ATM switching capabilities include scheduling and shaping of ATM based traffic. Operators can assign each virtual connection (VC) or virtual path (VP) to a service class, define the QoS parameters and shape the ATM egress traffic. ATM traffic policing allows operators to discard, tag or count nonconformant cells per configuration. BRIDGING LAN-To-LAN In addition to ATM and TDM over DSL backhauling, LAN to LAN bridging facilitates backhauling of Ethernet traffic originating from the cellular site/IP Node B towards the PSN. LAN-To-ATM LAN-to-ATM bridging, according to the RFC 1483/2684 requirements, allows backhauling Ethernet traffic originating from the cellular site/Node B over ATM core networks. ETHERNET OVER ATM Up to 32 Ethernet flows can be mapped into ATM VCCs. Ethernet flows can be defined as follows: • MPLS IMA • VLAN ID • MPLS over IP MPLS over GRE • PPPoE • DST IP • Inverse E1/T1 multiplexing over ATM (IMA) versions 1.0 and 1.1 allows users to define up to 4 IMA groups. VLAN ID + p-bits • • UDP over IP (TDM PWs only). • DST IP + IP-Precedence • DST IP + DSCP PWoATM allows carrying any type of pseudowire payload over AAL5 VC over any ATM or xDSL port (bridge PDU mode only). MPLS SUPPORT – LDP The MPLS label distribution protocol (LDP) is used to automatically assign and distribute pseudowires and tunnel labels between MPLS peers (LDPoMPLS according to RFC 3036/3037). Note: This functionality requires a software license as specified in the Ordering section. VB 5200 Mobile Backhauling Cell-Site Gateway CLOCK SYNCHRONIZATION PATH REDUNDANCY FIXED INTERFACES Robust clock synchronization and flexible timing modes include: Pseudowire and management traffic is protected by using two static routing paths with different priority values. Only one path is operational at a time, and its status is defined by the following: The chassis is also equipped with fixed E1/T1, Fast Ethernet and optional STM-1/OC-3c interfaces. • • • • • • Distribution and recovery of the 1588 high-precision clock (according to IEEE 1588-2008). Distribution and recovery of the clock on Ethernet interfaces (SyncE) according to the ITU-T G.8261/G.8262/G.8264 requirements. Clock recovery – a dedicated clock recovery module (optional) allows VB 5200 to adaptively recover the clock from a source device that distributes the ATM clock over a PSN. NTR clock recovery – VB 5200 supports clock synchronization via NTR over SHDSL. In this case, the DSLAM provides the clock reference via the DSL connection. Unicast clock distribution – the master clock is distributed with a dedicated stream towards up to 32 remote PSN peers via pseudowire connections Multicast clock distribution – the master clock is distributed towards the PSN using a single IP multicast clock stream (IGMPv2 host) via pseudowire connections. • E1/T1 clock transmission and recovery according to G.823/G.824. • Hardware ready for 2 MHz interface clock for external synchronization. Note: For the clock recovery feature, VB 5200 must be ordered with the “S, A or AS” suffix. For more information, refer to the Ordering section. • Physical link • IP-BFD (if the IP-BFD destination equals the static route next hop) • GRE keep-alive (for GRE interfaces) • Next hop ARP entry. VB 5200 supports up to 12 prioritized static routes. MODULAR INTERFACES The interface profile can be customized using interchangeable interface modules that can easily be inserted and extracted. Note: The modular interfaces are not hot-swappable. ADSL2+ Module The module includes two ADSL2+ interfaces, which support ADSL2+ over POTS (Annex A) and ADSL2+ over ISDN (Annex B), as well as auto-mode synchronization to ADSL/ ADSL2/ ADSL2+ (complying with G.992.1/ G.992.3/ G.992.5). SHDSL Module The module includes four SHDSL interfaces, which support SHDSL Annex A, Annex B and SHDSL.bis Annex F & G. SHDSL interfaces support the following bonding modes: • IMA • M-pair • EFM. GbE Module The module supports a single combo Gigabit Ethernet interface, which can be used for a network or user connection. E1/T1 Interfaces VB 5200 includes 8 or 16 E1 or T1 multiservice ports that can be configured to work in ATM UNI/IMA or TDM mode. This Any Service-Any-Port framework enables high flexibility in deployment within various backhaul solutions. The E1 ports are available with balanced or unbalanced interfaces (via an optional RJ-45 to BNC adapter cable). Fast Ethernet Interfaces VB 5200 includes four Fast Ethernet RJ-45 or SFP ports, used as user or network interface. The Ethernet ports can also be used for out of band management. The Ethernet interfaces can be ordered as electrical (RJ-45) or fiber optic ports. The fiber optic ports utilize hot swappable Ethernet-compliant SFPs, which are identical in structure to the STM1/OC-3c SFPs. STM1-OC-3c Interface VB 5200 can be ordered with one STM1/OC-3c TM SFP-based interface. Note: For more information, refer to the SFP Transceivers data sheet and to the Ordering section.
