ATMIII-PMC

Overview

The ATMIII-PMC card is a high performance PCI Mezzanine Controller designed for use in all aspects of telecommunications networks. The ATMIII-PMC supports port and protocol interworking between any two OC-3 and two GbE interfaces. It is ideal for demanding carrier applications in Wireless 2G, 3G, IMS, Internet access, Fixed/Mobile Convergence (FMC) and Next Generation Networks such as:

• 3G RNC, MSC, SGSN, and Node B
• Voice over Packet
• Video Streaming
• Broadband Networks
• ATM to IP Gateways

The ATMIII-PMC integrates easily into CompactPCI carrier boards and Single Board Computers (SBCs) for the optimal processing of high volume, multi-media traffic on emerging IMS mobile networks. With support for AAL2 and AAL5, the board has the capability for real-time voice and video over AAL2, as well as signaling and IP over AAL5 in 3G networks. The ATMIII-PMC is designed specifically for Node-B, RNC, SGSN and MSC applications over ATM. The PMC form factor enables the full utilization of slot space in a system. Multiple ATM cards can be installed together to provide a highly scalable, flexible and cost-effective solution. The ATMIII-PMC complements the existing PCI and cPCI intelligent controller family from Adax, giving customers maximum flexibility in platform choice.

The ATMIII-PMC enables development flexibility in building next generation infrastructure and can be configured in many ways depending on customer specifications and preferred architecture. This flexibility enables integrators to satisfy a wide range of requirements with a single common core architecture, saving development time and allowing customers to integrate their solutions ahead of the competition.

Application Overview

The ATMIII- PMC offers several different architecture options. Up to two PMC modules can be attached to a carrier card, with communication to the CPU occurring across the bus interface. For a higher performing solution, the Operating System of the application can be independent from that of the I/O by attaching the PMC module to a Single Board Computer (SBC). This independence allows the most suitable OS to be selected for different parts of the system. By attaching the ATMIII-PMC to an SBC, which is PICMG2.16 compliant, communication between the boards in the chassis occurs over the J3 port/via Ethernet, minimizing the bus as a point of failure in the system and increasing the reliability and availability of the solution. Ultimately, the ATMIII-PMC can be configured as a broadband signaling solution on a card. In the case of a SBC with Ethernet ports for connection to IP networks, the set up can act as a gateway between IP-based networks and broadband 3G Nodes.

The Adax ATMIII-PMC can be implemented throughout UMTS/3G network nodes, offering unparalleled flexibility for building SGSNs, MSCs, RNCs and Node-Bs, and making it the ideal solution for developers building crucial 3G infrastructure.

Serving GPRS Support Nodes (SGSN) and Mobile Switching Centers (MSC)

The ATMIII-PMC can sit beneath all the signaling protocol stacks in the SGSN and MSC in a UMTS network, with support for a variety of protocols simultaneously on the card. The Radio Access Network Application Part is the Radio Access Layer for the Iu Interface and is found in both the SGSN and MSC. Here, integration is at the MTP3b and M3UA level via SSCOP/SSCF and SCTP respectively. SSCOP/SSCF runs over AAL5 on the Adax ATM card. The Gateway Tunneling Protocol (GTP) in the SGSN runs over IP over Ethernet, and over AAL5 over ATM using Adax Frame Relay. GTP is supported by the Ga, Gn and Gp interfaces, which interconnect the SGSN to the GGSN and charging gateways.

Radio Network Controllers (RNC)

The Adax ATMIII-PMC supports both the Iu-PS and Iu-CS interfaces for which RANAP is the Radio Network Layer signaling protocol. As described above, Adax can fully support the RANAP stack using AAL5. In addition, the Iu-CS requires AAL2 transport, and the ATMIII-PMC can support the passing of AAL2 multiplexed traffic. This further completes the ability for the ATMIII-PMC to offer a solution for every node in a UMTS network. With the option of either OC-3/STM-1/STS-3c single/ multi-mode interfaces or T1/E1 interfaces, the ATMIII-PMC offers the ideal solution for any customer requiring 3G signaling.

Node-B

With support for AAL2, AAL5 and interworking between AAL2/5 and UDP/IP, the ATMIII-PMC provides high performance signaling and data transfer for the Node-B in UMTS networks. The Adax SSCOP/SSCF/AAL5 links can transfer the control plane traffic. The AAL2 subchannel with interworking feature can transfer and route the real-time user plane traffic. Consequently, the ATMIII-PMC can be deployed within every UMTS network node, from the edge of the Radio Network Subsystem right through into the heart of the Core Network. The ATMIII-PMC supports IMA for T1/E1. By splitting the ATM cells and sending them across T1/E1 lines from the RNC and reassembling them at the Node-B, this allows existing T1/E1 lines to be utilized while still benefiting from the higher bandwidth of broadband signaling.

Single Board Signaling Gateway

The commonality of software between Adax products means that the ATMIII-PMC can be used to migrate narrowband SS7/IP signaling gateways to broadband solutions with minimal change in higher layers. This commonality not only protects a customer’s investment in higher layer software and design time, but also enables customers to quickly and seamlessly utilize the higher bandwidth of broadband ATM solutions.

Adax has a complete set of solutions for next generation network infrastructure in a compact, reliable and scalable format using the ATMIII-PMC cards, which can be configured according to a customers preferred architecture.
