The ASR 5000 Platform

The ASR 5000 multimedia core platform is designed for deployment in multimedia-enabled core networks. It features a distributed architecture that allows all tasks and services to be allocated across the entire platform. This platform allows operators to deploy more efficient mobile networks that support a greater number of concurrent calls, optimize resource usage, and deliver enhanced services, while providing scalability.

ASR 5000 hardware components support the following features:

•	1:1 redundancy for all hardware elements

•	Hot-swappable sub-components

•	Inter-chassis session recovery (ICSR)

•	CLI support for telnet, SSH, and local login through a console port

•	SNMP support for event notification

ASR 5000 Chassis

Chassis Configurations

The system is designed to scale from a minimum configuration, as shown in the table below, to a fully-loaded redundant configuration containing a maximum of 48 cards.

If session recovery is enabled, the minimum number of packet processing cards per chassis increases from one to four cards. Three packet processing cards are active and one packet processing card is standby (redundant). This minimal configuration is designed to protect against software failures only.

Notes:

1. These numbers represent the minimum number of components for hardware redundancy. Additional components are required if Session Recovery is to be supported.

2. These numbers represent the minimum number of components for: a) hardware and software redundancy; b) platforms with combined services. Additional components are required if Session Recovery is to be supported.

3. PSCs and PSCAs can be mixed in the same chassis. However, in a mixed card environment, system capacity reverts to the lower limit of a PSC and incompatible components prevent the running of crypto functions. PSCs, PSC2s, PSC3s and PPCs must not be mixed with other packet processing card types.

4. This is the minimum configuration for redundant SGSN service and MME service.

5. This number varies based on network deployment requirements.

*The maximum number of half-height line cards you can install is 28. However, redundant configurations may use fewer than the physical maximum number of line cards since they are inactive behind standby packet service cards.

**The 10 Gigabit Ethernet Line Card (XGLX) is a full-height line card that takes up the upper and lower slots in the back of the chassis. When referring to an installed XGLC, use the upper slot number only. Slot numbering for other installed half-height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs.

Chassis Components (front and rear views)

This diagram shows exploded views of the front and rear chassis components. They are described below.

Chassis and Sub-component Identification Key

Item	Description
1	Chassis: Supports 16 front-loading slots for application cards and 32 rear-loading slots for line cards. To support the XGLC, a full-height line card, remove the half-height guide from the rear slots. The chassis ships with blanking panels over every slot except the following: 1, 8, 17, and 24. These are intentionally left uncovered for initial installation of application and line cards.
2	Mounting brackets: Support installation in a standard 19-inch rack or telecommunications cabinet. Flush and mid-mount options are supported. In addition, each bracket contains an electrostatic discharge jack for use when handling equipment.
3	Upper fan tray: Draws air through the chassis for cooling and ventilation. It then exhausts warmed air through the vents at the upper-rear of the chassis.
4	Upper bezel: Covers the upper fan tray bay.
5	Lower fan tray cover: Secures the lower fan tray assembly in place. The cover also provides an air baffle allowing air to enter into the chassis.
6	Lower bezel: Covers the lower fan tray bay.
7	Lower fan tray assembly: Draws ambient air through the chassis’ front and sides for cooling and ventilation. It is equipped with a particulate air filter to prevent dust and debris from entering the system.
8	Power Filter Units (PFUs): Each of the system’s two PFUs provides -48 VDC power to the chassis and its associated cards. Each load-sharing PFU operates independently of the other to ensure maximum power feed redundancy.

Chassis Description

Slot Numbering

The ASR 5000 chassis features a 48-slot design with 16 front-loading slots for application cards and 32 rear-loading slots (16 upper and 16 lower) for line cards.

Front Slot Numbering Scheme for Application Cards

The rear of the chassis features a half-slot design that supports up to 32 line cards:

Rear Slot Numbering Scheme for Line Cards

The following table shows the front slot numbers and their corresponding rear slot numbers.

Front and Rear Slot Numbering Relationship

Position	Slot Number
Front	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1
Rear Top Slots	32	31	30	29	28	27	26	25	24	23	22	21	20	19	18	17
Rear Bottom Slots	48	47	46	45	44	43	42	41	40	39	38	37	36	35	34	33

‌

Rear Slot Numbering for Half-Height Line Cards

Rear-installed line cards must be installed directly behind their respective front-loaded application card. For example, an application card in Slot 1 must have a corresponding line card in Slot 17. The redundant line card for this configuration would be placed in Slot 33. This establishes a directly mapped communication path through the chassis midplane between the application and line cards.

To help identify which rear slot corresponds with the front-loaded application card, the upper rear slot numbers are equal to the slot number of the front-loaded card plus 16. For example, to insert a line card to support an application card installed in slot 1, add 16 to the slot number of the front-loaded application card (Slot 1 + 16 slots = Slot 17). Slot 17 is the upper right-most slot on the rear of the chassis, directly behind Slot 1.

For lower rear slot numbers, add 32. Again, a redundant line card for an application card in Slot 1 would be (Slot 1 + 32 = Slot 33). Slot 33 is the lower right-most slot on the rear of the chassis, also behind Slot 1.

Rear Slot Numbering with Full-height Line Cards

ASR 5000 systems may be configured with 10 Gigabit Ethernet Line Cards (XGLCs). These are full-height line cards that require the removal of the half-height card guides to accommodate the cards. In this case, only the upper slot number is used to refer to the XGLC. For half-height cards installed with the XGLCs, the half-height slot numbering scheme is maintained.

For example, XGLCs installed in slots 17 and 32 also take up slots 33 and 48, but are referred to as cards in slots 17 and 32 only. The slots in which the SPIOs and RCCs are installed in the same configuration, are slots 24 and 25, and 40 and 41, respectively.

Mounting Options

The chassis is designed for installation in a standard (EIA-310-D, IEC 60297) 19-inch wide (482.6 mm) equipment rack or telco cabinet. Additional rack hardware (such as extension brackets) may be used to install the chassis in a 23-inch (584.2 mm) rack. Each chassis is 24.50 inches (62.23 cm) high. This equates to 14 Rack Units (1 RU = 1.75 in. [44.5 mm]).

You can mount a maximum of three ASR 5000 chassis in a 2- or 4-post equipment rack, or telco cabinet, provided that all system cooling and ventilation requirements are met. Three stacked chassis will occupy a minimum of 42 RUs.

There are two options for mounting the chassis in an equipment rack or telco cabinet:

•	Flush mount: In this configuration, the flanges of the mounting brackets are flush with the front of the chassis. This method is typically used with 4-post racks and telco equipment cabinets. This is the default configuration as shipped.

•	Mid-mount: In this configuration, the flanges of the mounting brackets are recessed from the front of the chassis. This method is typically used with 2-post racks. You must remove and re-install the mounting brackets in the middle of the chassis on both sides.

Caution: The equipment rack or cabinet hardware must not hinder air flow at any of the intake or exhaust vents. The ambient environment (conditioned space) must allow the system to function within its specified operating limits.

Midplane Architecture

The midplane separates the front and rear chassis slots. The connectors on the midplane provide intra-chassis communications, power connections, and data transport paths between the various installed cards.

The midplane also contains two independent -48 VDC busses (not shown) that distribute redundant power to each card within the chassis.

Midplane/Switch Fabric Architecture

Midplane and Bus Descriptions

Item	Description

5	Chassis slot number 17: upper right-most line card slot. The 10 Gigabit Ethernet Line Card (XGLC) is a full-height line card that takes up the upper and lower slots in the back of the chassis. Use the upper slot number only when referring to installed XGLCs. Slot numbering for other half-height lines cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs.
6	Chassis slot number 48: lower left-most line card slot

‌

The following subsections describe each bus.

320 Gbps Switch Fabric

The System Management Card (SMC) is an IP-based (packetized) switch fabric that provides a transport path for user data throughout the system. Its 320 Gbps switch fabric establishes inter-card communication between the SMCs and other application cards within the chassis along with their associated line cards.

32 Gbps Control Bus

The Control Bus features redundant 32 Gbps Ethernet paths that interconnect all control and management processors within the system. The bus uses a full-duplex Gigabit Ethernet (GigE) switching hierarchy from both SMCs to each of the 14 application card slots in the chassis. Each application card is provisioned with a GigE switch to meet its specific needs. This bus also interconnects the two SMC modules.

System Management Bus

The System Management Bus supports management access to each component within the chassis. It provides a communication path from each SMC to every card in the system with a 1 Mbps transfer rate to each card. This allows the SMCs to manage several low-level system functions (such as, supplying power, monitoring temperature, board status, pending card removals, data path errors, redundant/secondary path switchovers, card resets and failovers). Additionally, the System Management Bus monitors and controls the fan trays, PFUs, and alarming functions.

280 Gbps Redundancy Bus

The Redundancy Bus consists of multiple, full-duplex serial links providing packet processing card-to-line card redundancy through the chassis’ Redundancy Crossbar Cards (RCCs) as shown below.

RCC Logical View

Each RCC facilitates 28 links:

•	One link with each of the 14 packet processing card slots

•	One link with each of the line card slots

•	The RCC in slot 40 supports line card slots 17-23 and 26-32 (upper-rear slots)

•	The RCC in slot 41 supports line card slots 33-39 and 42-48 (lower-rear slots)

Each serial link facilitates up to 5 Gbps symbol rate, equivalent to 4 Gbps of user data traffic, in each direction. Therefore, the Redundancy Bus provides 140 Gbps symbol rate (112 Gbps user data) of throughput per RCC, 280 Gbps symbol rate (224 Gbps user data) total for both.

OC-48 TDM Bus

The system also hosts a dual OC-48 TDM bus consisting of 128 independent TDM paths each consisting of 512 DS0 channels. This bus supports voice services on the system. Higher speed TDM traffic requirements are addressed using the system’s data fabric.

SPIO Cross-Connect Bus

To provide redundancy between Switch Processor I/O (SPIO) cards, the system possesses a physical interconnect between the ports on the SPIOs. This cross-connect allows management traffic or alarm outputs to be migrated from an active SPIO experiencing a failure to the redundant SPIO.

While an SPIO should be installed directly behind its corresponding SMC, this bus allows either SMC to utilize either SPIO.

Power Filter Units

Located at the bottom rear of the chassis are slots for two 165-amp Power Filter Unit (PFU) assemblies. Each PFU provides DC power from the site’s power distribution frame (PDF) to the chassis and its associated cards. Each load-sharing PFU operates independently of the other to ensure maximum power feed redundancy. The maximum input operating voltage range of the PFU is -40 VDC to -60 VDC; the nominal range is -48 VDC to -60 VDC.

Important: The ASR 5000 does not offer an AC power supply option. If only AC power is available at the installation site, an adequately sized AC-to-DC converter will be required to supply -48 VDC power to the chassis.

The following drawing shows the PFU and its connectors.

‌

Fan Tray Assemblies

There are two fan tray assemblies within the chassis. A lower fan tray intakes ambient air and an upper fan tray exhausts warmed air from the chassis. Each fan tray is connected to both PFUs to ensure power feed redundancy. Both fan tray assemblies are variable speed units that automatically adjust fan speed based on temperature or failover situations.

Thermal sensors monitor temperatures within the chassis. In the event of a fan failure or other temperature-related condition, the SMC notifies all operable fans in the system to switch to high speed, and generates an alarm.

Lower Fan Tray

The lower fan tray assembly contains multiple fans and pulls ambient air into the chassis from the lower front and sides of the chassis. The air is then pushed upward across the cards and midplane to support vertical convection cooling.

Lower Fan Tray

Air Filter Assembly

The chassis supports a replaceable particulate air filter that meets UL 94-HF-1 standards for NEBS-compliant electronics filtering applications. This filter mounts above the lower fan tray assembly and removes contaminants before they enter the system. Temperature sensors measure the temperature at various points throughout the chassis. The system monitors this information, and generates a maintenance alarm, if necessary.

Particulate Air Filter

Important: A replacement air filter is shipped with each chassis. A minimum of one replacement air filter for each deployed chassis should be kept on site. This allows qualified service personnel to quickly replace the filter when necessary.

Upper Fan Tray

The upper fan tray unit contains multiple fans that exhaust air from the upper rear and sides of the chassis.

Upper Fan Tray

Chassis Airflow

Airflow within the chassis complies with Telcordia recommendations to ensure proper vertical convection cooling of the system.

Application Cards

The following application cards are supported by the system.

System Management Card (SMC)

The SMC serves as the primary system controller, initializing the entire system and loading the software’s configuration image into other cards in the chassis as applicable.

SMCs are installed in the chassis slots 8 and 9. During normal operation, the SMC in slot 8 serves as the primary card and the SMC in slot 9 serves as the secondary. Each SMC has a dual-core central processing unit (CPU) and 4 GB of random access memory (RAM).

There is a single PC-card slot on the front panel of the SMC that supports removable ATA Type I or Type II PCMCIA cards. Use these cards to load and store configuration data, software updates, buffer accounting information, and store diagnostic or troubleshooting information.

There is also a Type II CompactFlash™ slot on the SMC that hosts configuration files, software images, and the session limiting/feature use license keys for the system.

The SMC provides the following major functions:

•	Non-blocking low latency inter-card communication

•	1:1 or 1:N redundancy for hardware and software resources

•	System management control

•	Persistent storage via CompactFlash and PCMCIA cards (for field serviceability), and a hard disk drive for greater storage capabilities

•	Internal gigabit Ethernet switch fabrics for management and control plane communication

The front panel of the SMC with its major components is shown below:

7	Alarm Cut-Off (ACO) —Press and release this recessed toggle switch to reset the system alarm speaker and other audible or visual alarm indicators connected to the CO Alarm interface on the SPIO.

‌

SMC RAID Support

Each SMC is equipped with a hard disk, commonly referred to as a Small Form Factor (SFF) disk.

Important: The hard disk is not physically accessible. Disk failure constitutes an SMC failure.

If there is a redundant SMC in the chassis, the standby disk mirror the disk in the active SMC, forming an active Redundant Array of Inexpensive Disks (RAID).

HD RAID ids configurable via CLI commands. RAID control mechanisms allow xDR charging data to be written to the hard disks on both the active and standby SMCs for later upload to a suitable local or remote storage server.

Event logs related to disk and RAID include disk name, serial number and RAID UUID for reference. They are generated at the Critical, Error, Warning, and Informational levels.

Event logs at the Critical level are generated for service-affecting events such as:

•	RAID failure, including failures during runtime and various cases of initial RAID discovery and disk partition failures

•	File system failure when the system fails to initialize or mount file systems

•	Network failure for NFS server-related errors

Event logs at the Error level are generated for important failures:

•	RAID disk failure, including failures during runtime

•	Internal errors, including forking process failures

Event logs at Warning level are generated for important abnormal cases:

•	Overwriting a valid or invalid disk partition, RAID image, and file system

•	RAID construction in progress and possible failure

•	Low disk space

•	Files deleted to free up disk space

Event logs at the Informational level are generated for normal situations:

•	Disk partition completion

•	RAID discovery results without overwriting

•	RAID construction completion

•	RAID disk added or removed

•	File system initialization

•	NFS service start

•	Files copied/removed from CDR module to RAID disk

The hard disk supports SNMP notifications. These are described in the SNMP MIB Reference.

Packet Processing Cards: PSC, PSCA, PSC2, PSC3 and PPC

The packet processing cards provide packet processing and forwarding capabilities within a system. Each card type supports multiple contexts, which allows an operator to overlap or assign duplicate IP address ranges in different contexts.

Caution: With the exception of the PSC and PSCA, you cannot mix packet processing card types (PSCs, PSCAs, PSC2s, PSC3s or PPCs) in the same chassis.

Specialized hardware engines support parallel distributed processing for compression, classification, traffic scheduling, forwarding, packet filtering, and statistics.

The packet processing cards use control processors to perform packet-processing operations, and a dedicated high-speed network processing unit (NPU). The NPU does the following:

•	Provides “Fast-path” processing of frames using hardware classifiers to determine each packet’s processing requirements

•	Receives and transmits user data frames to and from various physical interfaces

•	Performs IP forwarding decisions (both unicast and multicast)

•	Provides per interface packet filtering, flow insertion, deletion, and modification

•	Manages traffic and traffic engineering

•	Modifies, adds, or strips datalink/network layer headers

•	Recalculates checksums

•	Maintains statistics

•	Manages both external line card ports and the internal connections to the data and control fabrics

To take advantage of the distributed processing capabilities of the system, you can add packet processing cards to the chassis without their supporting line cards, if desired. This results in increased packet handling and transaction processing capabilities. Another advantage is a decrease in CPU utilization when the system performs processor-intensive tasks such as encryption or data compression.

Packet processing cards can be installed in chassis slots 1 through 7 and 10 through 16. Each card can either Active (available to the system for session processing) or redundant (a standby component available in the event of a failure).

The front panel of a packet processing card with its major components is shown below.

Packet Processing Card (Generic)

Packet Processing Card (Generic) Callouts

Number	Description
1	Card Ejector Levers —Use to insert/remove card to/from chassis.
2	Interlock Switch —When pulled downward, the interlock switch notifies the system to safely power down the card prior to its removal.
3	Card Level Status LEDs —Show the current status of the card. (See Applying Power and Verifying Installation for definitions.)
4	Card Identification Label —Indicates the type of packet processing card. See the table at the end of this chapter.

‌

Packet Services Card (PSC)

Each PSC has two x86-based control processor (CP) subsystems that perform the bulk of the packet-based user service processing. The main x86 CP contains four cores split across two chips. It is equipped with 16 GB of RAM. Therefore, a fully-loaded system consisting of 14 PSCs, provides 224 GB of RAM dedicated to packet processing tasks. The second CP on the PSC is in the NPU. This CP contains 1.5 GB of memory, but only 512 MB is available to the OS for use in session processing. Hardware encryption devices are standard on the PSC.

Packet Services Card Type A (PSCA)

The PSCA is a direct replacement for the PSC and can be mixed with PSCs in the same chassis. It is an economical alternative for customers who wish to add more processing power to their ST40 or ASR 5000 chassis. Although the PSCA has a higher throughput capacity than the PSC, when mixed with PSCs, the PSCA will not overrun the PSCs. The PSCA can also be used to populate a new chassis for higher throughput than a PSC but for less cost and throughput than a PSC2.

Important: When PSCs and PSCAs are mixed in a chassis, incompatible components prevent the running of crypto functions. The chassis must also be configured to run in hybrid mode before PSCAs will be allowed to boot.

Packet Services Card 2 (PSC2)

The PSC2 provides increased aggregate throughput and performance, and a higher number of subscriber sessions in comparison with the PSC or PSCA.

The PSC2 uses a faster network processor unit, featuring two quad-core x86 CPUs and 32 GB of RAM. These processors run a single copy of the operating system. The operating system running on the PSC2 treats the two dual-core processors as a 4-way multi-processor.

The PSC2 has a dedicated security processor that provides the highest performance for cryptographic acceleration of next-generation IP Security (IPSec), Secure Sockets Layer (SSL) and wireless LAN/WAN security applications with the latest security algorithms.

PSC2s should not be mixed with PSCs, PSCAs, PSC3s. or PPCs. Due to the different processor speeds and memory configurations, the PSC2 cannot be combined in a chassis with other packet processing card types.

The PSC2 can dynamically adjust the line card connection mode to support switching between XGLCs and non-XGLCs with minimal service interruption.

PSC2 is fully redundant with a spare PSC2.

Important: ICSR is not supported between a chassis using PSC2s and a chassis using PSCs, PSC3s or PPCs due to the different capabilities of the two chassis.

Packet Services Card 3 (PSC3)

The PSC3 provides increased aggregate throughput and performance and a higher number of subscriber sessions than other ASR 5000 packet processing cards. Specialized hardware engines support parallel distributed processing for compression, classification, traffic scheduling, forwarding, packet filtering, and statistics.

The PSC3 features two 6-core CPUs and 64 GB of RAM. These processors run a single copy of the operating system. The operating system running on the PSC3 treats the two core processors as a 6-way multi-processor.

To optimize network efficiency and minimize down time, the system supports 1:n redundancy for PSC3s. If session recovery is enabled, the minimum number of PSC3s per chassis increases from one to four cards. Three PSC3s are active and one PSC3 is standby (redundant). This minimum configuration protects against software failures only. In addition to increased hardware requirements, Session Recovery may reduce subscriber session capacity, performance, and data throughput.

In the event of PSC3 failure, tasks are migrated from the active PSC3 to the standby card. The line card installed behind the PSC3 that was formerly active maintains the interfaces to the external network equipment. Redundancy Crossbar Cards (RCCs) provide a path for signaling and data traffic between the line card and the now active packet processing card.

PSC3s must not be mixed with PSCs, PSCAs, PSC2s. or PPCs.

The PSC3 is fully redundant with a spare PSC3.

Packet Processor Card (PPC) Description

The PPC is an economical alternative for smaller operators who do not require the throughput of PSC2s or PSC3s. It features a quad-core x86 CPU and 16GB of RAM. The processor runs a single copy of the operating system. The operating system running on the PPC treats the dual-core processor as a two-way multi-processor. The PPC supports CDMA, HA, and GGSN functionality.

A second-generation data transport fixed programmable gate array (FPGA) connects the PPC NPU bus to the switch fabric interface. The FPGA also provides a bypass path between the line card or Redundancy Crossbar Card (RCC) and the switch fabric for ATM traffic. Traffic from the line cards or the RCC is received over the FPGA serial links and is sent to the NPU on its switch fabric interface. The traffic destined for the line cards or RCC is diverted from the NPU interface and sent over the serial links.

A PCI-E interface allows the control processors to perform register accesses to the FPGA and some components attached to it, and also allows DMA operations between the NPU and the control processors’ memory. A statistics engine is provided in the FPGA. Two reduced latency DRAM (RLDRAM) chips attached to the FPGA provide 64 MB of storage for counters.

The PPC has a dedicated security processor that provides the highest performance for cryptographic acceleration of next-generation IP Security (IPsec), Secure Sockets Layer (SSL) and wireless LAN/WAN security applications with the latest security algorithms.

PPCs must not be mixed with PSCs, PSCAs, PSC2s, or PSC3s.

The PPC is fully redundant with a spare PPC.

Line Cards

The following rear-loaded cards are currently supported by the system.

Switch Processor I/O (SPIO) Card

The SPIO card provides connectivity for local and remote management, CO alarming, and Building Integrated Timing Supply (BITS) timing input. SPIOs are installed in chassis slots 24 and 25, behind SMCs. During normal operation, the SPIO in slot 24 works with the active SMC in slot 8. The SPIO in slot 25 serves as a redundant component. In the event that the SMC in slot 8 fails, the redundant SMC in slot 9 becomes active and works with the SPIO in slot 24. If the SPIO in slot 24 should fail, the redundant SPIO in slot 25 takes over.

The following shows the front panel of the SPIO card, its interfaces, and other major components.

7	BITS Timing Interface (Optional) —Either a BNC interface or 3-pin wire wrap connector. Used for application services that use either the optical or channelized line cards.
8	CO Alarm Interface—Dry contact relay switches, allowing connectivity to central office, rack, or cabinet alarms. See the Applying Power and Verifying Installation for more information.

‌

Management LAN Interfaces

SPIO management LAN interfaces connect the system to the carrier’s management network and applications, normally located remotely in a Network Operations Center (NOC). You can use the RJ-45 copper 10/100/1000 Mbps Ethernet interfaces or optical SFP Gigabit Ethernet interfaces to connect to the management network.

When using the RJ-45 interfaces, use CAT5 shielded twisted pair (STP) cabling.

Important: Use shielded cabling whenever possible to further protect the chassis and its installed components from ESD or other transient voltage damage.

SFP Interface Supported Cable Types

Module Type	Card Identification	Interface Type	Cable Specifications
1000Base-SX	Ethernet 1000 SX	Fiber, LC duplex female connector	Fiber Type: Multi-mode fiber (MMF), 850 nm wavelength Core Size (microns)/Range: • 62.5/902.23 feet (275 meters) • 50/1640.42 feet (500 meters) Minimum Tx Power: -9.5 dBm Rx Sensitivity: -17 dBm

‌

Console Port

The console uses an RS-232 serial communications port to provide local management access to the command line interface (CLI). A 9-pin-to-RJ-45 console cable is supplied with each SPIO card. The console cable must provide carrier-detect when attached in a null modem configuration.

Should connection to a terminal server or other device requiring a 25-pin D-subminiature connector be required, a specialized cable can be constructed to support DB-25 to RJ-45 connectivity. The baud rate for this interface is configurable between 9600 bps and 115,200 bps (default is 9600 bps).

BITS Timing

The Building Integrated Timing Supply (BITS) timing interface is optional and required only when the system is used in support of non-data applications. A BITS module is available on two versions of the SPIO: one supports a BNC interface and the other a 3-pin interface. If your system uses optical and/or channelized line cards for SDH/SONET, you can configure it to have the BITS module provide the transmit timing source, compliant with Stratum 3 requirements, for all the line cards in the chassis.

Central Office Alarm Interface

The CO alarm interface is a 10-pin connector for up to three dry-contact relay switches for connection to a CO alarm monitoring panel. The three Normally Closed alarm relays can be wired to support Normally Open or Normally Closed devices, indicating minor, major, and critical alarms.

A CO alarm cable is shipped with the product so you can connect the CO Alarm interfaces on the SPIO card to your alarming devices. The “Y” cable design ensures CO alarm redundancy by connecting to both primary and secondary SPIO cards.

Redundancy Crossbar Card (RCC)

The RCC uses 5 Gbps serial links to ensure connectivity between rear-mounted line cards and every non-SMC front-loaded application card slot in the system. This creates a high availability architecture that minimizes data loss and ensures session integrity. If a packet processing card were to experience a failure, IP traffic would be redirected to and from the LC to the redundant packet processing card in another slot. Each RCC connects up to 14 line cards and 14 packet processing cards for a total of 28 bidirectional links or 56 serial 2.5 Gbps bidirectional serial paths.

The RCC provides each packet processing card with a full-duplex 5 Gbps link to 14 (of the maximum 28) line cards placed in the chassis. This means that each RCC is effectively a 70 Gbps full-duplex crossbar fabric, giving the two RCC configuration (for maximum failover protection) a 140 Gbps full-duplex redundancy capability.

The RCC located in slot 40 supports line cards in slots 17 through 23 and 26 through 32 (upper rear slots). The RCC in slot 41 supports line cards in slots 33 through 39 and 42 through 48 (lower rear slots):

10 Gigabit Ethernet Line Card (XGLC)

The XGLC supports higher speed connections to packet core equipment, increases effective throughput between the ASR 5000 and the packet core network, and reduces the number of physical ports needed on the ASR 5000.

The XGLC (10G Ethernet) is a full-height line card, unlike the other line cards, which are half height. To install an XGLC, you must remove the half-height card guide to create a full-height slot.

The single-port XGLC supports the IEEE 802.3-2005 revision which defines full duplex operation of 10 Gigabit Ethernet. PSC2s or PSC3s are required to achieve maximum sustained rates with the XGLC.

The XGLC use a Small Form Factor Pluggable Plus (SFP+) module. The modules support one of two media types: 10GBASE-SR (Short Reach) 850nm, 300m over multimode fiber (MMF), or 10GBASE-LR (Long Reach) 1310nm, 10km over single mode fiber (SMF).

The XGLC is configured and monitored by the SMC via the system’s control bus. If the firmware needs to be upgraded. the XGLC uses the Star Channel for a faster download.

Install XGLCs in chassis slots 17 through 23 and 26 through 32. These cards should always be installed directly behind their respective packet processing cards, but they are not required behind any redundant packet processing cards (those operating in Standby mode).

The supported redundancy schemes for XGLC are L3, Equal Cost Multi Path (ECMP) and 1:1 side-by-side redundancy.

Side-by-side redundancy allows two XGLC cards installed in neighboring slots to act as a redundant pair. Side-by-side pair slots are 17-18, 19-20, 21-22, 23-26, 27-28, 29-30, and 31-32.

Side-by-side redundancy only works with XGLC cards. When configured for non-XGLC cards, the cards are brought offline. If the XGLCs are not configured for side-by-side redundancy, they run independently without redundancy.

When you first configure side-by-side redundancy, the higher-numbered slot’s configuration is erased and then duplicated from the lower-numbered slot. The lower-numbered top slot retains all other configuration settings. While side by side redundancy is configured, all other configuration commands work as if the side by side slots were top-bottom slots. Configuration commands directed at the bottom slots either fail with errors or are disallowed.

When you unconfigure side-by-side redundancy, the configuration for the higher-numbered top and bottom slots are initialized to the defaults. The configuration for the lower-numbered slot retains all other configuration settings. If you install non-XGLC cards in the slots, you may bring them back online.

Optical Line Card (OLC2)

The OLC2 is labeled OLC2 OC-3/STM-1 Multi Mode (or Single Mode depending on SFP type). The OLC2 supports either OC-3 or STM-1 signaling and ATM.

The OLC2 support both SDH and SONET. The basic unit of framing in SDH is STM-1 (Synchronous Transport Module level - 1), which operates at 155.52 Mbps. SONET refers to this basic unit as STS-3c (Synchronous Transport Signal - 3, concatenated), but its high-level functionality, frame size, and bit-rate are the same as STM-1.

SONET offers an additional basic unit of transmission, STS-1 (Synchronous Transport Signal - 1), operating at 51.84 Mbps—exactly one third of an STM-1/STS-3c. The OLC2 concatenates three STS-1 (OC-1) frames to provide transmission speeds up to 155.52 Mbps with payload rates of 149.76 Mbps and overhead rates of 5.76 Mbps.

The OLC2 optical fiber line card supports network connectivity through Iu or IuPS interfaces to the UMTS Terrestrial Radio Access Network (UTRAN). These interfaces are commonly used with our SGSN products to provide either non-IP 3G traffic or all IP 3G traffic (for all-IP packet-based networking) over ATM (Asynchronous Transfer Mode).

Each OLC2 provides four physical interfaces (ports) that are populated by Small Form-factor Pluggable (SFP) modules which include LC-type connectors. The Optical (ATM) line card supports two types of SFP modules (ports) and applicable cabling, but each card supports only one type at-a-time, as indicated in the following table.

 

Module Type	Card Identification	Interface Type	Cable Specifications
Single-mode Optical Fiber	ATM/POS OC-3 SM IR-1	Single-mode Fiber, LC duplex female connector	Fiber Types: Single-mode optical fiber Wavelength: 1310 nm Core Size: 9 micrometers Cladding Diameter: 125 micrometers Range: Intermediate/21 kilometers Attenuation: 0.25 dB/KM Min/Max Tx Power: -15 dBm/-8 dBm Rx Sensitivity: -28 dBm

Channelized Line Card (CLC2)

The CLC2 is also referred to as the Frame Relay line card. It provides frame relay over SONET or SDH. The CLC2 supports network connectivity through a gigabit interface to connect to the Packet Control Unit (PCU) of the base station subsystem (BSS) in a mobile network. These interfaces are commonly used with the SGSN product to support frame relay.

In North America, the card supplies ANSI SONET STS-3 (optical OC-3) signaling. In Europe, the card supplies SDH STM-1 (optical OC-3). The transmission rate for the card is 155.52 Mbps with 336 SONET channels for T1 and 252 SDH channels for E1.

Each CLC2 provides four optical fiber physical interfaces (ports). The ports are populated by a Small Form-factor Pluggable (SFP) modules which include an LC-type connector. The ports of the CLC2 supports two types of SFP modules and cabling, as shown in the following table.

Card Interlock Switch

Each card has a switch interlock mechanism that is integrated with the upper card ejector lever. The interlock ensures proper notification to the system before a card is removed. You cannot configure or place a card into service until you push the card interlock switch upward. This locks the upper ejector lever in place and signals the system that the card is ready for use.

Pulling the interlock downward to the unlocked position allows you to operate the upper ejector lever. This sliding lock mechanism notifies the system to migrate various processes on the card prior to its removal.

The following figure shows how the card interlock switch works in conjunction with the ejector lever.
