Overview
- Carrier Grade Transmission Equipment over Optical / Wireless Links
- Uses IEEE-1588v2 PTP synchronization technology
- Provides time-of-day and frequency synchronization to a single central GPS source with 0.5 micro-second (< 500 nanosecond) accuracy.
Uplink Network Interfaces (Any 4 user selectable ports)
- 4x10/100/1000BaseT / 4x1000Base SX/LX (use any 4 interfaces)
- Less than 4ms latency on all TDM (E1) over IP transmission links.
User Side Interfaces
- 8x10/100BaseT Ethernet Ports (4x10/100BaseT Ethernet Ports with PoE)
- 8x 100BaseFX Optical Ethernet Ports (SFP)
- 8x E1/T1 Interfaces
- 1x IRIG-B outputs
Features and Highlights
- IEEE-1588v2 Synchronous Ethernet PTP Clock
- 4 GigE Uplink Ports – Copper, Fiber, Copper + Fiber Gigabit Ethernet Ports.
- 4 x 10/100/1000BaseT Copper Ports or 4 x 1000BaseFX Optical Fiber Ports
(User selectable combination of only 4 Copper or Fiber Ports) - IEEE-1588 packet synchronization mechanism provides frequency and time-of-day synchronization for all points of the network to a common, single source.
- Industry ‘benchmark’ in transmission latency – less than 4ms for E1 Channels and 6ms for T1 Channels in IEEE-1588v2 (PTP Synchronization) versions.
- Fully managed Layer2 Switches which offer QoS by implementing IEEE 802.1p, 802.1Q VLANs and Differentiated Services (Diffserv) and packet priority classification protocols for traffic management and optimization.
Solution Highlights:
- Packet Optical Transport
- 1+1 Link Protection
- IEEE-1588v2 PTP Synchronization
- All Alarms and events time stamped to less than 500 nano seconds accuracy
- < 4 ms. Latency on TDM (E1 or T1)

Applications
Applications - Cellular / Mobile
With IEEE 1588 PTP Synchronization
- Reduce network latency to under 4ms for E1 Channels and 6ms for T1 Channels
- Synchronize all cell sites to a common clock (time-of-day) and frequency
- Frequency synchronize all BTSs and BSCs with the MSC using IEEE-1588 V2 phase synchronized frequency
- Distribute IEEE-1588v2, Time-of-Day (ToD) across all nodes of the network with 500ns (0.5 micro-second) accuracy
- Distribute 1 PPS and NMEA information across all nodes of the network.
Applications – Power and Transportation
- Frequency synchronization across the entire network with IEEE-1588 V2 phase synchronized frequency
