After reading the article a user would have gained understanding of technical specifications of Cisco ONS 15600 MSSP.

The article will educate a user about Cisco ONS 15600’s features such as scalability, patented cooling for high port-density long-reach optics, SONET/SDH DCC Processing Power, Management and provisioning, etc.

The Cisco ONS 15600 MSSP provides 320 gigabits of switching, grooming, aggregation, and bandwidth management capacity in a single shelf, with each 7-foot Network Equipment Building Systems (NEBS) 2000 rack supporting up to three shelves. Networkwide scalable capacity must extend through the edge and metro core and ultimately to service POPs. The Cisco ONS 15600 MSSP in conjunction with the Cisco ONS 15454 MSPP enables network scalability from the metro edge all the way to the services POP.

Patented Cooling for High Port-Density Long-Reach Optics
The Cisco ONS 15600 MSSP has a patented cooling system that enables it to provide 32 OC-192/STM-64 or 128 OC-48/STM-16/Gigabit Ethernet optical interfaces in a single shelf. This patented cooling system makes it possible for the Cisco ONS 15600 MSSP to scale to higher bit-rate interfaces such as OC-768/STM-256.

SONET/SDH DCC Processing Power Provides Full Visibility of the Network
The Cisco ONS 15600 MSSP is capable of terminating and processing hundreds of DCC channels simultaneously, allowing full network visibility. It is this inherent capability that allows end-to-end services to be provisioned and the complete network to be monitored through management software such as Cisco Transport Controller and Cisco Transport Manager.

Like the Cisco ONS 15454, the Cisco ONS 15600 MSSP uses advanced IP for DCC communications. However, Cisco realizes that many traditional metro edge network elements use the OSI protocol stack for DCC communication. Attempting to communicate with network elements which use OSI in their DCC channel is an interoperability limitation. To address this and to eliminate the need for colocated traditional network elements, the Cisco ONS 15600 MSSP uses the ITU G.7712 standard to terminate OSI-based DCC channels and forward the traffic to the data communication network (DCN) router. The G.7712 standard provides a framework for interworking between network elements that use OSI and IP in the DCC channel.

Management and Provisioning
With the Cisco Transport Controller, an easy-to-use Java-based, point-and-click craft graphical user interface (GUI), the Cisco ONS 15600 MSSP provides scalable bandwidths, easy switching and grooming, A-to-Z circuit provisioning, auto network element discovery with network topology, and custom bandwidth management, allowing service providers to design transport networks around subscriber needs rather than around equipment limitations.

The Cisco ONS 15600 MSSP is also supported by the Cisco Transport Manager. Cisco Transport Manager is the carrier-class element management system that provides advanced capabilities in the functional management areas of configuration, faults, performance, and security for Cisco optical network elements, subnetworks, and networks. Cisco Transport Manager is based on a client-server architecture that scales to support up to 3000 network elements and 100 simultaneous clients.

A user should note that the Cisco ONS 15600 MSSP meets all OSS/NMS and Operations Systems Modification of Intelligent Network Elements (OSMINE) requirements, supporting Transaction Language One (TL1), Common Object Request Broker Architecture (CORBA), Simple Network Management Protocol (SNMP), TIRKS, NMA, and TEMS interfaces.

The article will provide a reader with information and guidance on Carrier-class serviceability. The Cisco ONS 15600 MSSP offers servicing features to meet the high expectations of a carrier-class product.

• Backplane connector replacement
The Cisco ONS 15600 MSSP allows for the in-service replacement of backplane connectors if they are damaged. When repair is performed properly with the supplied tool, a backplane can be safely repaired without powering the system down.

• Fully hot-swappable
All system components, including line interface cards, common cards, fan trays, power distribution units (PDUs), and customer access panels, are fully hot-swappable, allowing a service technician to add and remove components without having to remove power from the system.

Carrier-Class Operations
Now, let’s have a look at the Carrier-Class Operations. The Cisco ONS 15600 provides carrier-class software features optimized for deployment in today’s large carrier networks.

• Fully nonblocking connectivity
Helps ensure that all connections made through the Cisco ONS 15600 are nonblocking, thereby providing a very high degree of network reliability.

• Errorless software upgrades
There are no bit errors observable in overhead or payload streams during a software upgrade on the Cisco ONS 15600. An upgrade is normally characterized by a bulk reconfiguration of the system database and/or a replacement of system software or firmware.

• Multiarea Open Shortest Path First (OSPF)
Enables network scalability to scores of nodes directly connected to the Cisco ONS 15600 MSSP.

• Security features
Security is a top priority for every service provider, because without effective security, provisioned circuits and service provider revenue are at risk. Several security features are provided to offer adequate protection for a service provider’s network:

– Firewall capability
Prevents users outside of the section data communication channel (SDCC) management network from sending traffic into the SDCC management network.

– Superuser-initiate
Allows the superuser to log out another user immediately.

– Password spinning
Allows a maximum number of login attempts, and blocks that username after the maximum number of attempts has been exceeded.

– Audit trail
Offers capability to archive the audit trail records.

– Timeout control
Times out a user session after a specified period of time has passed.

• Provisionable alarms
Alarm severity (critical, major, minor) as well as the service-affecting designation (rot reported, not alarmed) can be provisioned. The software also provides user-defined alarm profiles, along with a default alarm profile that is set to Telcordia or ITU specifications.

• Ease of use
The Cisco ONS 15600 MSSP software enables customers to perform operations, administration, maintenance, and provisioning (OAM&P) tasks in the most efficient manner possible. This is accomplished with such features as a Java-based craft interface (Cisco Transport Controller) self-install wizard, span upgrade wizards, and circuit provisioning wizards.

After reading the article, a user would have gained knowledge and understanding about Cisco ONS 15600’s Carrier-Class Serviceability

The article will provide a user with information and guidance on Cisco ONS 15600 MSSP Carrier-Class Reliability and Availability.

The Cisco ONS 15600 MSSP provides greater than five-nines reliability, or 99.9995 percent uptime. These reliability figures are a combination of numerous system-level and component-level attributes including:

• System components
The Cisco ONS 15600 MSSP uses components with life spans that well exceed the serviceability lifetime of the five-nines reliability. The use of high-availability components minimizes the chances of a failure because of a component fault. If there is a component fault, the entire Cisco ONS 15600 system is 1:1 protected to help ensure carrier-class availability.

• Restoration time
The Cisco ONS 15600 MSSP supports less than 25ms protection switching time, a 50 percent improvement over current industry standards.

• System exposure
Exposed reset buttons produce a higher probability of vulnerability to faults caused by external forces. To remove that exposure, the Cisco ONS 15600 MSSP eliminates exposed reset buttons that could be pressed inadvertently.

• Power
The power feeds need to be extremely robust when compared to a typical wire feed and must provide a mechanically rigid power delivery system that would be extremely difficult to displace. Each power feed to the Cisco ONS 15600 MSSP is carried over individually laminated solid metal bars that also provide an integrated approach to power filtering. These power feeds are fully redundant and fully isolated. The power feeds supply power to the A and B power bus bars, which in turn provide power to each shelf component through the redundant power backplane. If one of the power feeds fails, each shelf component automatically selects the working power backplane in an error-free transaction.

• Automatic shutdown
If both central office power feeds fail, the Cisco ONS 15600 MSSP performs an orderly, sequenced system shutdown. This “graceful shutdown” feature allows the platform to power down in an orderly and predictable manner, helping ensure that the platform sustains no damage and the system is ready to return to service when the central office/service point of presence (POP) fault is repaired.

• SONET/SDH backplane
The Cisco ONS 15600 MSSP has fully redundant backplane connectivity to the line interface cards and the cross-connect cards. The Cisco ONS 15600 MSSP traffic moves from the interface cards to the cross-connect cards and back by traffic being placed on both copies of the backplane. Each backplane trace on both copies is constantly monitored for quality. If errors are detected within the system, a hitless redundant copy switch is performed.

• Control backplane
Similar to the other data paths on the Cisco ONS 15600 MSSP, control signals are sent to each shelf component over a fully redundant control backplane.

• Timing
The Cisco ONS 15600 MSSP provides an internal stratum 3E clock, providing extended holdover when operating in an internal timed mode. This timing or timing derived from an external BITS or line-timed source is provided to each of the shelf components through a redundant timing backplane.

Additionally, Multipoint Switch cascading is supported to enable meetings with up to 90 screens. Please note that only static meetings are supported when cascading.

Impromptu Calling
During an active meeting, the conference manager can add another party from the web interface and the participant is automatically added to the meeting. The automated-Attendant capabilities on the Multipoint Switch allow any Cisco TelePresence endpoint to dial into a scheduled meeting. After a user enters the conference ID that the Automated-Attendant requests, a user is joined into the appropriate meeting.

High Performance and Low Latency
The high-performance Cisco TelePresence Multipoint Switch server provides very low latency, allowing natural conversation and quick multipoint switching between Cisco TelePresence meeting rooms.

Audio Add-On
Remote, audio-only participants can join a meeting by using conferencing features on the meeting-room phone or by integrating an audio conferencing bridge into the meeting in both point-to-point and multipoint calls.

Director Controls
For special events, custom video switching and audio mixing are often required. It is now possible using the web-based controls in the Cisco TelePresence Multipoint Switch Administration.

Encryption
The Cisco TelePresence solution supports full media and signaling encryption with no discernable latency to the Cisco TelePresence call for up to 48 screens. In addition, Cisco TelePresence meetings can be designated as nonsecure, secure best effort, and always secure. Meeting encryption status is indicated on-screen at the start of a call or when it changes, and on the phone at all times.

Video Announce
This configurable option allows new participants joining a meeting to briefly be shown on the displays of all participants already in the meeting so they know a new party has joined.

Bandwidth Management
Automatic camera transmission control significantly reduces network traffic by eliminating the data feeds of nonspeaking meeting participants. Each meeting can be assigned a maximum quality (rate). If a Cisco TelePresence endpoint that has been assigned a lower bandwidth rate joins, the bandwidth rate of the conference automatically decreases.

IBM and HP jointly held the number 1 position in the worldwide server market with 30.5% and 29.8% factory revenue share respectively for 2Q11, a statistical tie. IBM experienced 24.5% year-over-year growth in factory revenue gaining 1.6 points of share in the quarter on the performance of System x, Power Systems, and System z. HP’s factory revenue grew 9.3% year over year in 2Q11 based on solid demand for x86-based ProLiant servers and blades. Dell maintained third place with 13.8% factory revenue market share in 2Q11.

Dell’s factory revenue increased 5.1% compared to 2Q10, driven in part by strong demand from SMB customers. Oracle and Fujitsu jointly held the number 4 position with 7.2% and 6.5% factory revenue share, respectively, in 2Q11. Oracle’s 2Q11 factory revenue increased 4.2% compared to 2Q10, driven in part by improved demand for x86-based Exadata systems. As a direct result of the large scale K-computer HPC system in Japan, Fujitsu experienced a sizable 133.6% year-over-year improvement in server revenue.

Top Server Market Findings

• The market for non-x86 servers, including servers based on RISC, EPIC (Itanium-based), and CISC processors, increased 23.3% year over year to $4.8 billion in 2Q11. This is the third consecutive quarter in which non-x86 servers have exhibited positive growth and the second consecutive quarter that non-x86 based system revenue has grown faster than the market overall. Growth in non-x86 server revenue was driven by improved demand for Unix servers and IBM System z platforms.

• Unix servers experienced a second consecutive quarter showing year-on-year factory revenue improvement, growing 1.5% when compared to 2Q10. Unix server revenues were $2.9 billion, representing 22.0% of quarterly server revenue in the quarter. IBM’s Unix server revenue increased 14.0% year over year in the quarter, as IBM gained 6.0 points of Unix server market share.

• IBM’s System z servers experienced the fourth consecutive quarter of positive revenue growth, with 61.1% year-over-year growth in 2Q11 to $1.2 billion, representing 9.0% of quarterly server revenue worldwide. This was the fourth consecutive quarter that IBM System z revenue exceeded $1 billion, driven by new product introductions and demand for capacity within the IBM installed base.

• Linux server demand increased for the seventh consecutive quarter in 2Q11, with revenue growing 47.5% to $2.7 billion when compared with the second quarter of 2010. Linux servers represent 20.5% of all server revenue in the quarter as Linux server demand was helped significantly by Fujitsu’s large scale K-computer HPC system in Japan.

• Microsoft Windows server demand also continued to show strong growth as Windows-based hardware revenue increased 12.4% year-over-year. Quarterly revenue of $5.9 billion for Windows servers represented 45.5% of overall quarterly factory revenue and 71.0% of all quarterly server shipments.

“The Unix server marketplace is seeing some rebound in revenue, based on technology refresh for Unix server products from all major vendors,” said Jean S. Bozman, research vice president, Enterprise Servers at IDC. “This segment was hard-hit in 2009 and 2010 during the economic downturn as customers deferred or delayed acquisition of midrange and high-end Unix servers.
