TRANSITION NETWORKS | PB-ISDN-4U-NT-AC-NA | Quad BRI port unit. 2-wire BRI NT interface. Internal AC Power supply. 1 Gigabit SFP port for fiber connectivity.

  • Réf. fabricant PB-ISDN-4U-NT-AC-NA
  • PART #555063
Type of Device: ISDN ACCESS

The PacketBand-ISDN-4x-x delivers transparent switched ISDN data services across packet networks. All ports are synchronized with central, or network clocks, providing a fully clock-locked environment across asynchronous packet networks - no there is no data loss due to free-running and slipping clocks. This system provides ISDN over Ethernet/IP networks for both voice and more critically, data applications

  • Product supports 4 x ISDN BRIs
  • 4-wire "S" interface (NT or TE)
  • 2-wire "U" interface (NT-User presentation)
  • US-ANSI and Euro-ETSI ISDN available
  • (2) 10/100/1000 Base Ethernet ports
  • 1 x 1GE SFP cage
  • AC power only, transmits all/any data and voice protocols over packet networks
  • Totally transparent to all data formats
  • All PacketBands and interfaces locked to the same clocks
  • Various clocking options with high quality clock recovery
  • Any "B" channel can dial any other on the packet network, or "break-out/in" to the PSTN via a PRI/BRI "gateway"
  • Provides low-cost migration to IP networks for legacy equipment, low data overheads
  • Configurable packet size- Compensates for "jitter" or packet delay variation
  • Re-orders packets; Very low latency or processing delay; Local ethernets support rate limiting
  • Quality of Service (QoS) options, VLAN and double VLAN tagging, full cross-connectivity
  • A-law to u-law conversion- Support for contention or over-booking- Call progress tone generation
  • Number manipulation/conversion/LCR, automatic primary/secondary/tertiary routes
  • Routing profiles can be scheduled at different times of the day/week
  • ISDN layer 2 and layer 3 message capture and log for analysis
  • Easy and intuitive to configure via GUI management package, Compact table-top with optional rack-mount extenders, Optional 19 Inch rack-mount kits
