eXmux - Model 3501 -Teleprotection System
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.
Transfer Trip over Ethernet/IP/MPLS
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
