Features and Highlights

• Gigabit Ethernet, Voice & Data Multiplexer.
• Transmission medium can be either of the following:
• Fiber (1000Base-LX or 1000Base-FX Optical Gigabit)
• Copper (10/100/1000BaseT Ethernet)
• Wireless (Ethernet / IP Radios / E1 Radios).
• Uses IEEE-1588v2 PTP synchronization technology.
• Uses E1 over Packet / TDM over IP / E1 over Ethernet / technology to transport legacy Voice, Data, IRIG-B Time Code and Teleprotection Channels over Gigabit Ethernet / IP links.
• < 4ms latency on the E1 / T1 channels.
• Delivers error free transmission of E1, 2-wire and 4-wire Voice, Synchronous and Asynchronous Data, C37.94 Teleprotection and IRIG-B time over Ethernet / IP / MPLS networks with Stratum 1 (GPS Synchronized) or Stratum 3E level of accuracy.
• Integrated IEEE C37.94 Teleprotection Interfaces.
• Integrated, 8 x IRIG-B interfaces for RTU time-of-day synchronization to a single central GPS source with 0.5 micro-second (500 nanosecond) accuracy.
• 2.048 MBits and Phase-Locked 2.048 MHz Frequency Outputs for accurate synchronization clock distribution over the entire network.
• Suitable for Smart Grid applications.
• Multiple user side Fast Ethernet, Power over Ethernet (PoE) and Gigabit Ethernet Port options for audio or video conferencing applications.
• 1+1 Network Link Protection / Network Port Redundancy on both 'East' and 'West' side.
