STM1 Network Solution in the Largest Power Utility Company of Kenya

Situation

The largest power utility company in Kenya wants to extend its SCADA system to cater for existing distribution stations in the different regions of the country. However, the cost of their current core STM-4/16 network would be too high in case it is used for SCADA applications. The customer finally decides to build an independent STM-1 ring network strictly to transport SCADA services with low latency, deterministic transport paths and larger capacity.

Solution

Loop offers a cost-effective STM1 (SDH, PDH) ring network solution and deploys Loop-IP6820 GBE self-healing switch at the station where RTU’s communication protocol is 104 and IP6810 for RS232 Serial communication. At SFH level, the O9500R with 8GESW high-speed plugin card is used to encapsulate Ethernet traffic to be carried over SDH (EoS) network. Loop-IP6820 offers both GBE LAN Ports and WAN Trunk ports which can be the ideal solution for future Ethernet Data Transport expansions. The high speed 8GE card provides a reliable way to carry a large haul of Ethernet Traffic over SDH (EoS) Network for faster Data switching and transport.

                                                   The simple solution diagram is shown below.

Public Transportation

In many ways, a telecommunication network often mirrors a physical transportation network -- thus the old phrase "information superhighway" used to refer to the internet. However, physical transportation networks such as roadways and railways often require their own separate communication network to relay alarm and status information to human ...

TDM over Ethernet

The move from a TDM (time division multiplexing) based network to an Ethernet or IP-based packet switched network is gradual and necessary in order to improve performance and keep costs down. However, this switch is being approached different ways depending on if the customer is a telecom carrier, utility, financial institution, or other indus...

Enterprises & Offices

While not as physically demanding as large factories, offices require strong communication networks as well. Many companies seek better ways to organize their traffic and this is where the IP6510-LN and the IP6610 can help. Our devices can add VLAN tags to direct traffic. They can also aggregate company leased lines for more efficient use. Vid...

Management

Every network needs to be managed. All Loop devices support SNMP and SSH into a remote terminal. Loop-iNET and LoopView allow you to change settings through a GUI format, and also switch easily between multiple devices. For complex network features such as circuit provisioning, Loop-iNMS fulfills customer needs. Loop products support both inba...
