IPS-803GSM is a managed industrial grade Ethernet switch that is designed to meet the demands of power substation systems and is fully compliant with the requirement of IEC 61850-3 and IEEE 1613. The switch provides a variety of redundant functions to increase the reliability of your communications system, including redundant and isolated power supplies (24/48 VDC) and 110/220 VDC/VAC). The managed Ethernet functions include STP/RSTP/MSTP/ITU-T G.8032 ERPS and multiple µ-Ring for redundant cabling, layer 2 Ethernet IGMP, VLAN, QoS, ACL, Security, IPv6, bandwidth control, port mirroring, cable diagnostic and Green Ethernet. Housed in rugged DIN rail or wall mountable enclosures,these switches are designed for harsh environments,such as power substation networks (See Figure). The series product can be managed centrally and conveniently by CTC Union's SmartView™ Element Management System or other third party SNMP managers.



IEEE 1588 PTP V2

These switches  support IEEE 1588 PTP V2 for precise time synchronization.  Each port may be configured independently  to operate in Ordinary-Boundary,  Peer to Peer Transparent Clock,  End to End Transparent Clock, Master, or Slave mode.  Accuracy is measured in nanoseconds, making it suitable for time sensitive applications such as mobile phone networks, military systems and large scale financial networks.
