Product SummaryRAD's ACE-3105 cell-site gateway utilizes widespread wholesale ADSL2+ and SHDSL.bis deployments over copper infrastructure for cost-effective delivery of GSM, UMTS and HSDPA mobile broadband services over ATM, PSN or hybrid transport networks. The ACE-3105 grooms fractional E1/T1 UNI, several IMA (Inverse Multiplexing over ATM) links, circuit-emulated (CES) E1/T1 TDM lines, or Ethernet links onto a single network interface. In addition, it employs standard pseudowire emulation (PWE) capabilities and advanced clock recovery mechanisms, enabling carriers to transparently provision ATM and TDM services over IP DSLAMs and packet-switched networks. Benefits• The only entry-level DSL modem gateway in the market with built-in pseudowire capabilities• Lowers backhaul OpEx by optimizing RAN bandwidth utilization through grooming of underutilized E1/T1 channels and ATM statistical multiplexing• Simultaneously delivers 2G/3G traffic and supports multi-generation cell site colocation• Ensures service reliability and differentiated QoS through traffic classification and shaping• Supports gradual migration to PSN networks• Allows limited space installations with small size and total front access design Further Product InformationRAD's ACE-3105 multiservice cell-site gateway is specifically 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 HSPA traffic over the same transport network. Working opposite the ACE-340x and ACE-3600, the ACE-3105 minimizes capital investment and shortens service rollout times by leveraging available DSL infrastructure to access ATM, SDH/SONET and high capacity, economical packet switched networks. Advanced QoS, pseudowire and OAM featuresThe advanced ATM shaping and scheduling capabilities of the ACE-3105 permit operators to implement overbooking strategies, enabling them to optimize network utilization, conserve existing resources and reduce the number of leased services required to support their network. The device also enables operators to converge multi-generation traffic over an all-IP RAN by using IMA/UNI or standards-based CES/SAToP pseudowire (PW) encapsulation. These are enhanced with various QoS schemes, including VLAN priority (802.1p), EXP or ToS/DSCP, as well as comprehensive monitoring and diagnostic capabilities, including pseudowire VCCV-BFD and ITU-I.610 ATM OAM. In addition, the ACE-3105 uses PPP over Ethernet (PPPoE) protocol to allow HSDPA connectivity in a variety of DSL-based cellular backhaul applications. Full range of standard synchronization optionsThe ACE-3105 is designed to provide highly accurate synchronization over packet transport and meet the key requirements for cellular backhaul, such as +/-16 ppb (parts per billion) frequency accuracy. The clock can be recovered either from the TDM links or from the DSL links, using NTR recovered clock over SHDSL or adaptive clock recovery (ACR). SNMP Management and securityThe ACE-3105 features flexible management capabilities, including local management via an ASCII terminal (RS-232). In addition, remote management can be performed either inband or out-of-band, using the network or user ports. Advanced FCAPS (Fault, Configuration, Accounting, Performance, Security) and diagnostic tools are provided by RADview-EMS, RAD's carrier-class element management system, via an SNMP-based GUI. The ACE-3105 also supports a variety of configuration access channels, including CLI over Telnet, SNMP, Web server, and TFTP. Incorporated security features include Secure Shell (SSH), Web-based Secure Socket Layer (SSL), SNMPv3, and RADIUS, as well as management access control list (ACL).
