The eXmux® 3501 Teleprotection System provides an integrated end-to-end teleprotection function in the eXmux® 3501 IP Access Multiplexer. The teleprotection system comprises of an eXmux® TPS Interface Unit and a 1 RU TPS I/O Box, providing a teleprotection channel over Ethernet/IP or MPLS network using TDM over IP. It is mid-span compatible with the IMUX 2000 T1/E1 multiplexer MTS Teleprotection system.
The eXmux® 3501 Teleprotection system provides 4 bidirectional transfer trip commands point-to-point between two peer units or between one unit and an IMUX 2000 MTS unit. The system allows the transport of two independent 4 function inputs/outputs; in addition to 2 controlling inputs logic and 2 outputs for alarming & status for each TPS I/O unit.
Provides Teleprotection channel over an Ethernet/IP or MPLS network
Programmable Logic
Supports a number of programmable logic functions including auxiliary controlling inputs
Communication Interface
Two independent 64kb/s DS0 using TDM over IP technology with future option to include Serial to IP with encryption
Inputs/Outputs
4 Optically isolated inputs with 2 auxiliary controlling inputs logic and 4 outputs with solid state and relay options
Sequence of Events (SOE)
Maintains 1500 SOE records, each time stamped with 1 ms accuracy and synchronized via NTP/SNTP or IEEE 1588 network timing signals
IMUX 2000 MTS Compatibility
Mid-span compatibility with IMUX 2000 T1/E1 multiplexer MTS Teleprotection module for ease of migration to IP
Hitless Teleprotection Channel
Teleprotection channel packets are sent simultaneously both ways around the ring for a zero-data-loss path recovery, providing high dependability/availability using TDM over IP
User Friendly Interface
User interface via the slickest eXmux® 3501 Visual Network Management Software for an effortless user friendly experience and easy system management
Point-to-Multipoint Functionality*
Future capability to include point-to-multipoint communications providing integrated multipoint Teleprotection functionality between multiple substations (*Future)

Network Diagram Example
The above example is a typical communication network using the RFL eXmux® 3501 TPS.
The eXmux® 3501 IP Access Multiplexer comes with an advanced Graphical User Interface (GUI) Network Management Software for Operations, Administration, Maintenance and Provisioning (OAM&P). The intuitive and user friendly eXmux® 3501 VNMS is designed to allow the user to manage their eXmux® 3501 network, making configuration, port mapping, network monitoring and diagnostics simple and easy.
The VNMS communicates using the latest SNMPv3 for authentication and encryption along with cyber security features meeting NERC requirements. The Network view provides the user an overall view of the network and the status of each node in the network and is further enhanced by allowing the user to graphically represent the physical interconnection of each node in the network. The Node view displays a virtual physical view of the unit as configured with real-time status information. Programming details of each module are easily accessible by a simple double click on the module.
The uniquely designed Port Mapping interface allows the user to easily map any port on an eXmux® 3501 to any other eXmux® 3501 on the network by a simple point and click (“Map this Port”) function. The dynamic Current Active Alarm view gives the user specific information as to which node is in alarm, the type of alarm, the source and the description of the alarm so that diagnostic can be straightforward and quick. The “Tooltip” function provides the user “On-demand” information on any setting, status and alarm from any screen without the need for a manual or cumbersome Help function.
