SEL University will be offering training courses for the SEL ICON in spring and fall 2023.
SEL has released firmware upgrades for the Nx64F, Async, and Async Data—Channel Bank submodules. This fixes an issue that can cause the submodule circuit not to fail over correctly when a Protected Line Module (PLM) or Enhanced Protected Line Module (EPLM) is rebooted or removed. We recommend upgrading as soon as possible and before performing any updates to the PLM or EPLM on your network.
We released new firmware that addresses recently identified issues with the SEL ICON’s time synchronization subsystem. These issues have the potential to impact the stability of the network under certain timing reference conditions. The new firmware also provides enhancements that improve the resiliency of the network during time interruption events.
The latest versions of DS1 Sync Submodule and Server Module firmware introduced two new features. Users can define the severity of Loss of Signal alarms as Minor or Major, depending on whether the port is a line or access port. In addition, interoperability with third-party voice modules has been improved with Robbed Bit Signaling.
SEL has released a full set of DS1 Async and DS1 Sync Submodules, functionally equivalent to and hot-swappable with installed counterparts. These alternatives will help address a supply chain issue with an FPGA part used in SEL ICON submodules.
SEL has released a new version of the SEL 5051/5052 Client/Server Network Management System Software and Server Module Firmware R127. These updates address a supply chain issue with a field-programmable gate array device used in various ICON modules.
SEL offers significant enhancements in its newly released version of the SEL-5051/5052 Client/Server Network Management System Software.
A new firmware release for the Transfer Trip Module (TTM), Firmware R105, provides an increase in the latency alarm threshold from 2–15 ms to 2–30 ms.
A new firmware release adds DS1 line timing support for the Enhanced Protected Line Module (EPLM), Firmware R101-V1, and the DS1 Sync Submodule, Firmware R102-V1. This timing support enables the SEL ICON to synchronize to an external DS1 reference or BITS clock.
SEL’s newly released line module, the Enhanced Protected Line Module (EPLM), is fully backwards compatible with the existing Protected Line Module (PLM) and provides significant new capabilities to the SEL ICON platform.
SEL’s recent release of Version 18.104.22.168 of the SEL-5051/5052 Client/Server Network Management System (NMS) Software provides support for the Enhanced Protected Line Module (EPLM) and Async Data CB Submodule.
SEL released a new access module to provide support for EIA-232, EIA-422, and EIA-485 circuits when operating as a DS1 channel bank.
An SEL ICON network can now synchronize to an external DS1 reference or BITS clock using the latest firmware release for the Protected Line Module (8021-01) and DS1 Sync Submodule (8057-02) that adds DS1 line timing support.

SEL has released several new enhancements for the SEL ICON platform and SEL-5051 Client and SEL-5052 Server Network Management System (NMS) software.
We have released new versions of the SEL-5051 Client Network Management System (NMS) Software and SEL-5052 Server NMS Software.
SEL has released new firmware for the SEL-8053-01 Async Submodule and the SEL-8021-01 Protected Line Module (PLM).
We have recently added support for 10, 20, and 50 Mbps bandwidths in virtual synchronous networking (VSN) transport mode. We also added several new usability tools to the SEL-5051 Client and SEL-5052 Server Network Management System (NMS) Software.
Two new SEL ICON firmware versions add support for single-fiber GigE small form-factor pluggable (SFP) modules for VSN mode and Ethernet virtual wire (EVW) and Bridge Protocol Data Unit (BPDU) support for SONET-only mode.
In October 2017 SEL released a firmware upgrade for the SEL ICON Protected Line Module to support deterministic packet transport. This new capability allows the ICON to interoperate more effectively with other devices and packet-based networks while maintaining the deterministic performance require for critical protection circuits.
SEL has released a new client server implementation of the ICON Network Management System (NMS). The client server architecture provides a solution for efficiently managing multiple users’ access to an ICON network. The software uses a centralized server to manage physical connectivity between the client and ICON network, provide user authentication, and manage access privileges.
SEL has released a series of new features for the SEL ICON Integrated Communications Optical Network, including a new access submodule and an updated version of the SEL-5051 Network Management System (NMS) Software.
To address the challenges of providing low-latency deterministic communications for critical applications, managing legacy TDM services, and migrating to packet-based transport, we are developing a solution that combines TDM with deterministic packet transport to provide the best of both technologies.
SEL has released new firmware for the SEL-8030 Server Module, SEL-8020 Line Module, and SEL-8021 Protected Line Module as well as an updated version of SEL-5051 Network Management System (NMS) Software. This new release provides network security managers with the ability to manage authorization by “separation of duty” requirements for each user on the ICON Integrated Communications Optical Network.
SEL has released new firmware for the SEL-8030 Server Module and an updated version of the SEL-5051 Network Management System (NMS) Software to provide support for multiple individual user accounts and the ability to report system events and alarms in syslog.
This month, we are excited to introduce several new products and features for the SEL ICON Integrated Communications Optical Network multiplexer! Together with ongoing additions to the ICON SEL-5051 Network Management System (NMS) Software, SEL is excited to introduce two new access modules, a new ICON chassis form factor, two new supported network topologies, and a new Firmware Lock option to help simplify managing your network.
If you are using an external timing source to synchronize your ICON network and are also using IRIG-B, you need to take action now to prepare for the next leap-second event, which will occur on Tuesday, June 30, 2015. Every node that has an external timing source connected to the IRIG-B input on the ICON Server Module (SEL-8030) will require an adjustment. This is true even if the IRIG-B serves as a backup timing source for nodes that use GPS as a primary timing source. Nodes that use GPS for network timing with no IRIG-B input do not require any action, as the GPS system updates them automatically.
Since the last edition of ICON News, SEL has introduced several new enhancements for the SEL ICON Integrated Communications Optical Network platform. These include the ability to build branched linear spurs off ICON ring networks as well as a new release of the SEL-5051 Network Management System Software that includes the new Circuit Wizard functionality.
New ICON firmware releases are now available to address IRIG-B time quality assurance, undetected bit errors after an SSM event change, and the potential for misreporting Power Over Ethernet (PoE).
A new revision of the SEL-5051 NMS software and firmware updates for the SEL-8030-01 Server Module and SEL-8053-01 Async Module were released on July 8, 2014.
A typical ICON network relies on optical fiber to provide a high-bandwidth communications path between sites. However, it is not always possible to install fiber at every site. For these situations, it is possible to use a microwave radio to create a path to a remote site or provide a link to complete a ring topology. A new application guide is now available that shows how the ICON can operate over an Alcatel-Lucent 9500 Microwave Packet Radio system.
SEL released new firmware for the Server Module (R111) on March 12, 2014, which corrects potential missed detection of ICON inventory changes, status alarms, and log entries after 497 days of continuous operation.
The SEL ICON has been enhanced to support two fiber-optic Gigabit Ethernet access ports on the SEL-8020 Line Module. You can use these new GigE connections (ports E and F) to connect to the SEL-2730M 24-Port Ethernet Switches' upstream ports or to other local high-speed intelligent electronic devices (IEDs) within a substation.
The new SEL-3400 IRIG-B Distribution Module is the perfect complement to the ICON Integrated Communications Optical Network. Including the SEL-3400 allows you to time-synchronize more devices and adds new capabilities to your system.
