RAD's ACE-3200 cell-site gateway (CSG) connects one or several base stations (BTSs) and node Bs, over shared access lines, to ATM, SDH/SONET or PSN backbones. Featuring “Any-Service-Any-Port” functionality, the ACE-3200 CSG incorporates flexible port configuration to allow grooming of circuit-emulated (CES) TDM E1/T1s, fractional E1/T1 UNIs or several IMA links into a single IMA, STM-1/OC-3 or Fast Ethernet network interface. Incorporating pseudowire technology with high precision clock recovery capabilities, it supports effective delivery of 2G TDM and 3G ATM services over Ethernet, IP or MPLS networks.
- Expands network capacity and enables controlled introduction of 3G services with no additional capital investments in infrastructure
- Reduces CapEx using economical STM-1/OC-3 ports in the transport network
- Lowers OpEx by aggregation and optimization of deployed SDH/ATM equipment, reducing overall number of network links
- Improves network efficiency by employing statistical traffic multiplexing, performance monitoring and end-to-end QoS attributes, requiring fewer technician truck rolls
- Enables cost effective multi-generation service integration and efficient handling of real-time and delay-tolerant traffic over any transport
- Supports balanced migration to PSN backhaul
- Saves on 2G/3G colocation costs with smallest device in the market
RAD’s ACE-3200 cell site gateway is specifically designed to accommodate the rapid expansion in mobile backhaul traffic resulting from the widespread deployment of new cellular services such as 3G mobile broadband and rich-media communications. It simplifies service provisioning and control by supporting 2G/3G colocation and enabling simultaneous delivery of GSM, UMTS and next-generation 3GPP services over the same transport network. Working opposite the ACE-340x and ACE-3600 aggregation site gateways, the ACE-3200 minimizes capital investments and shortens service roll-out times by leveraging available ATM and SDH/SONET infrastructure. Additionally, it optimizes RAN efficiency, thereby offsetting the cost of increased bandwidth capacity, reduce operating expenses and protect operator revenues.
Reduce cellular backhaul expenses through aggregation and overbooking
The ACE-3200 connects one or several base stations (BTSs) and node Bs to ATM, SDH/SONET or PSN backbones, over shared access lines. Featuring “any service any port” functionality, it incorporates flexible port configuration to allow aggregation of circuit-emulated (CES) TDM E1/T1s, fractional E1/T1 UNIs or several IMA links into a single IMA, STM-1/OC-3 or Fast Ethernet network interface.
This minimizes the number of overall network links and facilitates the use of lower-priced, higher bit-rate STM-1/OC-3 ports in network edge switches, instead of costly E1/T1 links or deployment of additional switches. Mobile operators can therefore allocate their backhaul resources more effectively and reduce the number of leased services required to support their networks, consequently lowering their backhaul capital expenditures (CapEx).
Furthermore, by supporting inherent ATM QoS attributes, the ACE-3200 RAN backhaul solution enables service differentiation and traffic engineering, including prioritization, shaping and scheduling. Together with ATM’s statistical multiplexing nature, this allows operators to optimize network utilization by implementing overbooking strategies, thereby reducing service costs and operating expenditures (OpEx).
Emulated TDM/ATM services over PSN
Packet transport offers great savings in backhaul costs and enables scalable adaptation to required bandwidth capacity. The ACE-3200 supports operators in carrying out a step-by-step transition to PSNs, for example by separating real-time GSM/TDMA and UMTS voice/video traffic from delay-tolerant HSDPA traffic, using a hybrid of PSN and deterministic TDM or ATM transport networks. Alternatively, operators can converge multi-generation traffic over an all-IP RAN, using ATMoPSN, CESoPSN or SAToP pseudowires, with accurate synchronization and clock distribution mechanisms, as well as with various encapsulation and QoS schemes for delivering ATM and TDM traffic over L2 and L3 networks.
Timing and synchronization
Synchronization in cellular networks is critical to ensure proper quality for mobile services. As radio access networks (RANs) are rapidly transitioning to asynchronous packet switched technologies, which introduce packet delay variation and packet loss, timing distribution and recovery have become a major challenge in the migration to IP backhaul.
With powerful synchronization capabilities, the ACE-3220 ensures highly accurate delivery of 2G, 3G and 4G traffic over packet backhaul. It enables mobile operators and transport providers to eliminate the risk of service disruptions, impaired cell hand-offs and excessive dropped calls, thereby supporting reliable transmission of real-time traffic over PSNs. It also ensures QoS priorities for clock traffic and supports “SDH/SONET or Better” performance requirements for voice and video traffic, such as up to 16 ppb (parts per billion) frequency accuracy.
The ACE-3220’s SyncToPTM suite enables clock recovery either from the TDM links, the DSL link or from the Ethernet links, using PTPv2 (IEEE 1588v2), Synchronous Ethernet (Sync-E), NTR recovered clock over xDSL, or adaptive clock recovery (ACR). In addition, it features a built-in input clock interface. The ACE-3220 also enables packet timing distribution, using adaptive clock or IEEE 1588v2, as well as physical clock distribution via the TDM and Ethernet links. Furthermore, it provides unique flexibility in supporting the simultaneous use of different clock transfer methodologies, for example, employing 1588v2 to receive the clock from the network then distributing it to the cell-site with Sync-E.
