ATCA Hardware platform (1/2) •
Nokia Siemens Networks ATCA HW platform is based on the Advanced Telecommunications Computing Architecture (AdvancedTCA or ATCA) specifications
•
The configuration consists of ATCA blades, advanced mezzanine cards (AMC) and rear transmission modules (RTM) housed within an ATCA shelf.
•
It is possible to install three ATCA shelves into one cabinet.
ATCA hardware building blocks The ATCA hardware architecture allows network elements to be created from a set of basic hardware building blocks. - Cabinet: provides enclosure for up to three shelves - PDU:
power feed from site power feed to shelf-level power modules
- Shelf:
provides enclosure, cooling, power and HW management to blades and RTMs
- Blades: (front boards): blades plug into the front side of the shelf. - RTMs:
(rear boards): rear transition modules plug into the backside of the shelf. RTMs are extension modules for blades.
- AMCs:
advanced mezzanine cards plug into the AMC bay of a blade.
All field replaceable units (FRUs) are hot-swappable, meaning that they86can be removed TM51155EN04GLA2 and replaced without shutting down the entire unit. ATCA shelf © Nokia Solutions and Networks 2014

Power feed system (1/2) Shelf power feed concept •
Power distribution units (PDUs)
- There are two power distribution units (PDUs) for each shelf, located between the shelf and the cabinet frame on the rear side of the cabinet.
Shelf power feed concept
- Each PDU has two -48/-60 VDC inputs for the site power feed (protected by 60 A circuit breakers), and four -48/-60 VDC outputs to the power entry module (protected by 30 A fuses). The PDU provides protection against surges and transients in the battery feed cables. •
Power entry modules (PEMs)
- There are two power entry modules (PEMs) for each shelf, located on the lower rear side of the shelf. Each PEM provides power terminals for four (25 A) power feeds from its dedicated PDU in the shelf. Each power feed from the PDU to the PEM consists of one physical cable, which includes a -48/60 VDC conductor and its return conductor. - PEMs provide -48/-60 VDC via backplane to the blades, fan modules and shelf managers. AMCs and RTMs receive their power via the blade to which they are connected to. TM51155EN04GLA2 88 power feed subsystem - The is fully redundant: one PDU-PEM pair/ alone can

Power distribution to units
- Blades, fan modules and shelf managers receive their power from the PEMs via the shelf backplane. AMCs and RTMs receive their power via the blade to which they are connected to. - Shelf managers generate a 3.3 V auxiliary supply voltage to the PEMs, fan modules, shelf alarm panel, shelf alarm display and shelf data modules. - Each PEM consists of four power segments (feeds) that share common management, control and supervision functions. - The backplane powerfeeds are divided into four segments. 89

CPU Blade ACPI2-A The ACPI2-A ATCA CPU Blade SAS is a central processing unit (CPU) in the AdvancedTCA system. The ACPI2-A is a single-width blade that can be equipped to any node slot in the ATCA shelf. The ACPI2-A supports: - Dual 1000Base-T Ethernet for the base interface - Dual 1000Base-BX Ethernet for the fabric interface - Serial attached SCSI (SAS), connected to the AMCs and RTMs - Additional interfaces such as USB, serial ports, dual IPMB - Dual 1000Base-BX from the backplane fabric interface to the AMC bays - Linux and DMX operating systems

Ethernet interface ETHAM-A Ethernet AMC •
External interfaces to Ethernet networks in Flexi NS are based on ETHAM-A Ethernet AMC. This means that Ethernet interfaces are connected directly from the computer units without any integrated switches.
•
It can be used both for user plane (such as up/downlink data) and control traffic (such as O&M).
•
ETHAM-A is installed into the AMC bay of a ACPI2-A CPU blade, with all packet processing relayed to the CPU blade.
•
ETHAM-A does not rely on any processor of its own. It has four RJ-45 connectors and can function in 10 Mbit/s (10Base-T), 100 Mbit/s (100Base-TX) or 1 Gbit/s (1000Base-T) mode.
•
ETHAM-A Ethernet AMC does not contain any software related to network interfaces as it is part of the operating system that runs on the CPU blade.

Hard Disk drive
Hard disk drive carrier AMC (HDSAM-A) •
The hard disk drive carrier AMC (HDSAM-A) is a mid-size AMC
providing serial attached SCSI (SAS) storage in the AdvancedTCA (ATCA) system. The AMC complies with AdvancedTCA and AdvancedMC specifications of the PICMG. •
The HDSAM-A is equipped in the AMC bays on the CPU blade.
•
The HDSAM-A is equipped with a 2.5-inch small form factor serial
attached SCSI (SAS) hard disk drive. •
Serial Attached SCSI (SAS) protocol is used as a storage solution. SAS uses serial communication instead of the parallel method found in traditional SCSI devices but still uses SCSI commands for interacting with SAS devices. The maximum data transmission capacity through this interface is 3 Gbit/s. In this solution the hard disks are simply implemented as AMCs which can be shared by two CPU blades using SAS cabling through RTMs.

Hub Blade AHUB2-A • AHUB2-A Hub Blade implements the LAN switching functionality for both Base Interface (BI) and Fabric Interface (FI). AHUB2-A is used to connect computer units inside a single shelf together. It is always duplicated within the shelf. It is located in the shelf’s physical slots 8 and 9. • The hub blade provides connections for two types of internal networks: - Base interface (BI) switch for the network elements internal traffic (for communication between computer units inside a single shelf) - Fabric interface (FI) switch for communicating with the outside world as well as for the network element’s internal user data communication (for example, user data transmitted through AMC modules).

Rear transition module (RTM) Rear transition module ARTM2-A for CPU blade •
The ARTM2-A ATCA CPU Blade RTM provides additional connectivity for the CPU
blades in the AdvancedTCA system. The ARTM2-A is a singlewidth rear transition module (RTM) which can be equipped into any node blade RTM slot where the CPU blade is located. It is accompanied by the ACPI2-A and controlled by the unit computer of the ACPI2-A (it can not be used without ACPI2-A). In Flexi NS it implements redundant SAS HDD and switchover connections of 2N units (OMU and MCHU). In other units ACPI2-A operates without ARTM2-A. •
The ARTM2-A can be used for:
- SAS disk cross-sharing: redundant CPU blades can access each other's hard disks - wired alarms - providing a serial port connection for the blade

Interconnection of blade, RTM, AMC and backplane Interconnection of blade, RTM, AMC and backplane •
The hardware implementation of functional units in ATCA HW Platform is based on blades, RTMs and AMCs. Their interconnection is presented in the figure.
•
The blade is connected directly to the backplane and the RTM Zone 1 connectors are used for power connection, testing and hardware management. Zone 2 is reserved for the data transport through fabric and base interfaces. Zone 3 provides I/O interconnection between blade and RTM.
interconnection of blade, RTM, AMC and backplane
• The RTM is connected only to the blade (it has no direct connection to the backplane). The CPU Blade has two AMC slots in front panel.

•
Marking and Charging Unit (MCHU) uses the ACPI2-A blade coupled with an ARTM2-A rear transition module
•
Signalling and Mobility Management Unit (SMMU) uses the ACPI2-A blade
•
Control Plane Processing Unit (CPPU) uses the ACPI2-A blade

Principal Requirements for Next Generation Gateways
Throughput • High bandwidth consuming Internet and multimedia services are driving the bandwidth demand – VoIP increasing the number of small packets
Signalling • Flat network architecture increasing requirements for signalling performance
Scalability • Future network architecture requires flexibility for a centralized or distributed gateway deployment and capacity to support traffic growth and always on bearers
Reliability • Packet switched networks will need to fulfill the reliability requirements of CS networks on longer term as VoIP becomes reality
Functionality • To add value in Internet and service connectivity, operators need to be able to manage the traffic in their networks
Operability • Easy operability drives down OPEX 110
