What’s Cell C?

Many people do not know what is cellC, of course, more do not know its usage cough up! For a kind of new things, people to its eye is very unique! Not only to give it a trial, and worry of being ripped off. In fact, I am also very understand why people will often have such a psychological. So, in order to relieve people's hearts confusion, I am here to write an article introduces Cell C.

Cell C's network has 90% population coverage as of the end of 2011, the balance catered for by Vodacom data coverage. Cell C had completed its technological migration to a new sophisticated core switching network so the network can cope with any unprecedented traffic demand Roaming agreements exist with over 550 telecommunication soperators in more than 187 countries.Cell C has spent over R5-billion (US$660 million) on its state of the art HSPA+. The network supports speeds up to 21 MB/s and 42MB/s, and is available in most parts of South Africa. The 900 MHz band has been re-farmed to provider greater coverage compared to other operators. Despite all of the recent upgrades, there are still areas of urban Johannesburg that do not have adequate signal.

In order to become more competitive and address the new segments by way of the revised product and service value proposition, Cell C took the next step to improve its time to market and level of service. For that, the company decided to migrate from its more than 128 existing IT systems to a platform designed by a single provider, eliminating the need for gateways and the recurrent adaptations they required, which were slowing down the company.
As the implementation of the NGBSS would literally beam Cell C into a new future, the project was called “BEAM.” Speed became a very crucial element to Cell C’s strategy. Not only did Cell C decide to implement a new BSS solution, but it also decided that this transition needed to happen at a very fast pace. Cell C would only sign a contract with a provider that could agree to implement the solution within a six-month time frame (from the initial Cell C requirements specification to cutover). It also required that the actual cutover to the new NGBSS system be a one-time migration event over a single weekend, minimizing any problems it might create.
After clearly identifying its needs and requirements, Cell C consulted with several renowned BSS providers for the solution that would best meet its needs. However, Huawei was the only company that could actually deliver a solution that closely met Cell C’s requirements within the demanding delivery time frame.
Huawei went the extra mile to understand the business challenges caused by Cell C’s service convergence and rising customer sophistication. By leveraging its extensive telecommunications and IT expertise and in-depth benchmarking analyses of Cell C's current business and operations, Huawei supported Cell C's business and strategic IT transformation through the delivery of an end-to-end NGBSS solution.
The solution was implemented based on the application of industry best practices, including customer relationship management (CRM), IP contact center (IPCC), convergent billing system (CBS), mediation and provisioning coupled to a single integration platform.
As mentioned before, one of the concerns raised by Cell C was the time taken to implement the new system. Aside from the actual implementation, the company also required all existing products, services and customers to be migrated from their legacy system into the new system, all within the same aggressive delivery time frame. Both Huawei and Cell C understood that this would represent the world’s first brownfield migration of an entire BSS system within the time frame proposed.
In order to comply with Cell C’s requirements, Huawei went through detailed planning, executing several dry runs and data migration testing. The actual delivery of the NGSS system took 11 months total, and while this was longer than the originally contracted delivery period, it remains a world first. The project delays were accepted in order to provide additional business assurance about service functionality, as well as to provide assurance through additional cutover readiness preparation. In summary, the project was delivered in less than one year and the cutover took no longer than 18 hours, with the overall impact of the migration on customer experience kept to a minimum.huawei switches price
After extensive testing, the cutover process was executed along a strict timetable on Saturday, Feb. 5, 2011, with the actual transfer of services taking just five hours, leading into six hours of post-migration testing. Cell C shops and retail outlets were back online doing business by noon on Sunday, Feb. 6, 2011, after closing at normal business hours on Saturday. The continued post-cutover support allowed Cell C to make smooth progress in the final post-cutover steps, resulting, as mentioned, in minimal impact to its clients. All business-critical issues (i.e., those related to customer operations and service lines) were resolved in the first two weeks after the cutover.
It is also important to mention that this successful transition was made possible not only by Huawei’s commitment to its client, but also by Cell C’s own commitment to the new strategy. “The full engagement of Cell C’s executive team in this transition speeded up the process and allowed for the migration to happen as quickly and as smoothly as possible,” said Michael Ansley, the program director for BEAM and also the company’s executive in Business Partnerships.huawei switches products.
This full commitment was also embraced by Cell C’s marketing team, which launched a PR campaign. The objective was to inform all of Cell C’s customers of the transitions the company was undergoing and what they should expect from the new Cell C after they were completed. This strategy had a very positive impact and generated a lot of trust among Cell C’s customers, which certainly helped to minimize any possible client churn.
Ansley also highlighted the importance of Huawei’s technical expertise and transparency during the process. Also integral to the success was a very competent Cell C program management team, who developed a real-time migration dashboard through which Huawei and Cell C had full visibility of hundreds of migration-related activities and schedules taking place throughout the cutover process.
“It helped Cell C not only to understand all of the steps and challenges of the process, but also to effectively (and in real time) to plan for and communicate changes to migration team members, executives and business stakeholders spread countrywide,” said Ansley.

I think, now if you see this article psychological will probably have to understand what is the Cell C, also can understand his original try but why has been in doubt and not the cause of action now. In fact, Cell C gives users 10 free extra airtime minutes for every R10 (accumulated) spent on recharging. The qualifying period of the free minutes runs from Monday 00H00 to Sunday 23H59. The offer is available to all pre-paid customers.Cell C started a mobile broadband price war in 2010, introducing South Africa's most affordable prepaid data sticks. In advertising the service, Cell C claimed it was offering a 4G network, whereas it used HSPA+. South Africa's Advertising Standards Authority (ASA) ruled that the company should to stop using the term 4Gs in its advertising material. Even though the technology CellC used is described 4G worldwide.^[Other services from Cell C,

includVideomessaging,HSPA+, MMS, internet, Voicemail, Blackberry, etc.

Now, you should have no doubt! I'm happy you see I write this article. I wish a happy life

Product Features ,Powerful Surge Protection

• The S3300 adopts the Huawei patented built-in surge protection technology that can effectively defend against lightning induced over-voltage. Each port has a surge protection capability of 6 KV. Compared with the conventional surge protection design, the Huawei patented surge protection technology greatly reduces the possibility of lightning damage on the device in severe environments or even in scenarios where grounding cannot be implemented.Unique Fan-Free Design

• In the S3300 series, three non-PoE models that have 24 electrical ports adopt a fan-free design, which dramatically reduces the power consumption and noise of the device. In addition, this design reduces mechanical faults and protects the device against damages caused by condensed water and dust.

• The S3300 adopts next-generation highly-integrated chips and power-saving circuit design to ensure even heat dissipation. It also supports idle port sleep to further reduce power consumption.

• The S3300 emits low radiation and complies with the radiation standards of electric appliances, so it has no harm to human body and is more environmentally friendly.Powerful Service Support

• The S3300 supports enhanced selective QinQ by using chips. This function adds outer VLAN tags to packets without occupying ACL resources to support multi-service provisioning.

• The S3300 supports 1,024 multicast groups (the 33HI supports 2,048 multicast groups) and protocols including IGMP snooping, IGMP filter, IGMP fast leave, and IGMP proxy. The S3300 supports line-speed cross-VLAN multicast replication, multicast load balancing among bundled ports, and controllable multicast, meeting requirements for IPTV and other multicast services.

• The S3300 supports Multi-VPN-Instance CE (MCE) to isolate users of different VPNs on a device, ensuring user data security and reducing customer expenditures.

• Multiple models of the S3300 support PoE and comply with IEEE 802.3af and 802.3at (PoE+). By using this function, the S3300 can supply power over the Ethernet to the connected standard PDs such as IP Phones,WLAN APs, and Bluetooth APs. Each port can provide up to 30 W of power. This reduces the power cable layout and management cost for terminal devices. The S3300 can also be configured to provide power for PDs at specified time as required.Security and QoS

• The S3300 provides various security protection measures. It can defend against Denial of Service (DoS) attacks, attacks to networks, and attacks to users. DoS attacks include SYN Flood attacks, Land attacks, Smurf attacks, and ICMP Flood attacks. Attacks to networks refer to STP BPDU/root attacks. Attacks to users include bogus DHCP server attacks, man-in-the-middle attacks, IP/MAC spoofing attacks, DHCP request flood attacks, and DoS attacks by changing the CHADDR field of packets.Product Brochure Qu di way® S3300 Switches

• The S3300 listens to the MAC/IP address, address lease, VLAN ID, and port number about a DHCP user by establishing and maintaining a DHCP snooping binding table. In this way, IP addresses and access ports of DHCP users can be tracked. The S3300 directly discards invalid packets that do not match binding entries, such as ARP spoofing packets and packets with bogus IP addresses, to prevent hackers or attackers from initiating man-inthe-middle attacks to campus networks by using ARP packets. The trusted port feature of DHCP snooping is used to ensure the validity of the DHCP server.

• The S3300 supports strict ARP learning to prevent ARP spoofing attackers from exhausting ARP entries so that authorized users can connect to the Internet. It also supports IP source check to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP address spoofing. The URPF function provided by the S3300 can check packet transmission paths to authenticate the packets received, which can protect the network against the spread of source address spoofing attacks.

• The S3300 supports centralized MAC address authentication and 802.1x authentication. User information such as the user account, IP address, MAC address, VLAN ID, access port number, and flag indicating whether antivirus software is installed on the client can be bound statically or dynamically, and user policies (VLAN, QoS,and ACL) can be delivered dynamically.

• The S3300 can limit the number of source MAC addresses learned on a port to prevent attackers from exhausting MAC address entries by using bogus source MAC addresses. In this way, MAC addresses of authorized users can be learned and flooding is prevented.

• The S3300 can implement complex traffic classification based on information such as the five-tuple, IP priority,ToS, DSCP, IP protocol type, ICMP type, TCP source port number, VLAN ID, Ethernet frame protocol type, and CoS. The S3300 supports inbound and outbound ACLs. The S3300 supports flow-based two-rate three-color CAR. Each port supports eight priority queues, WRED congestion prevention mechanism, and multiple queuescheduling algorithms such as WRR, DRR, SP, WRR+SP, and DRR+SP. This ensures the quality of voice, video and data services.

Good Expandability and High Reliability

• The S3300 switches support Intelligent Stacking (iStack) and plug-and-play. Multiple S3300s start to construct a virtual switch automatically after being connected by stacking cables. Stacked switches are classified into active, standby, and slave switches. After a standby switch is configured, the duration of service interruption caused by faults on the active switch is reduced. The S3300 supports intelligent upgrade, freeing customers from upgrading the software version of a switch after adding the switch to a stack. Utilizing the iStack technology, multiple switches can be interconnected to expand the system capacity and can be managed by using a single IP address,which greatly reduces the cost of system expansion, operation, and maintenance. Compared with traditional networking technologies, iStack has advantages in expansibility, reliability, and system architecture.Product Brochure

• Besides the traditional STP, RSTP, and MSTP, the S3300 supports enhanced Ethernet reliability technologies such as Smart Link (applicable to tree networks) and RRPP (applicable to ring networks), which implements millisecond-level protective link switchover and ensures network reliability. In addition, the S3300 supports multi iinstance for Smart Link and RRPP to implement load balancing among links, further improving bandwidth usage.

• The S33HI supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer of an Ethernet network. SEP is applicable to open ring networks and can be deployed independently from the upper-layer aggregation devices to provide millisecond-level switchover without interrupting services. SEP features simplicity, high reliability, high switchover performance, convenient maintenance, and flexible topology,enabling customers to manage and deploy networks conveniently.Considerate Maintenance-Free and Manageability

• The S3300 adopts a unique maintenance-free design and supports automatic configuration (auto-config), freeing network administrators from heavy configuration workload when deploying a batch of sites.

• The S3300 supports BFD and provides millisecond-level detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network reliability. Complying with IEEE 802.3ah and 802.1ag, the S3300 supports point-to-point Ethernet fault management to detect faults on user links. Ethernet OAM improves the network management and maintenance capabilities on the Ethernet and ensures a stable network. The S33HI provides hardware-based OAM and BFD functions and supports 3.3-millisecond high-precision detection.

• The S3300 supports port-based and VLAN-based traffic statistics and NQA, which enables network administrators to better manage networks.

• The S3300 supports the GARP Registration Protocol (GVRP). The GVRP technology implements dynamic configuration of VLANs. In a complex networking environment, GVRP can simplify VLAN configuration and reduce network communication faults caused by incorrect configuration of VLANs. This reduces the manual configurations of network administrators and ensures correct VLAN configurations.Various IPv6 Features

• The S3300 hardware supports both IPv4 and IPv6, IPv6 over IPv4 tunnels (including manual tunnels, 6-to-4 tunnels, and ISATAP tunnels), and Layer-3 line-speed forwarding. Therefore, the S3300 can be deployed on IPv4 networks, IPv6 networks, and networks that run IPv4 and IPv6 simultaneously. This makes the networking flexible and meets the requirements for the network transition from IPv4 to IPv6.

• The S3300 supports various IPv6 routing protocols including RIPng and OSPFv3. It uses the IPv6 Neighbor.Discovery Protocol (NDP) to manage packets exchanged between neighboring nodes. The S3300 supports the .Path MTU Discovery (PMTU) mechanism. That is, it selects a proper MTU on the path from the source to the destination to optimize network resource usage and obtain the maximum throughput.Applications Serving as Access Devices in Buildings The S3300 can connect to 100-Mbit/s DSLAMs as an aggregation switch in buildings. In this case, the selective QinQ function is configured on the S3300; outer VLAN tags identify the locations of the DSLAMs or campus, and the inner VLAN tags identify users. The S3300 can also connect to home gateways directly or supply power to PSEs such as wireless APs or IP phones through PoE. This enables the S3300 to better support multi-service deployment, unified planning, fine management, and convenient maintenance of customers.
