Kentrox DataSMART IDSU T3 E3 Intelligent DSU


The DataSMART® T3/E3 IDSU provides powerful access for bandwidth-intensive Frame Relay and high-speed router applications. With a selectable T3 or E3 network interface, the DataSMART IDSU supports worldwide enterprise applications. And with a HSSI and V.35/EIA-530/X.21 data port, the versatile IDSU supports almost any data requirement. For maximum flexibility, these data ports support both full T3/E3 bandwidth and variable clock rates in Nx.5 Mbps increments. These variable clock rates allow users to control the amount of bandwidth utilized. Ideal for carrier backbone connectivity, this IDSU can support router and Frame Relay backbone applications. The DataSMART IDSU is also ideal for enterprise networks requiring increased bandwidth for Internet and corporate LAN access traffic.


• HSSI or V.35/EIA-530 data port for a variety of data equipment
• Selectable data port clock rates for fl exible connectivity
• Embedded SNMP and TELNET for advanced network management
• Extensive monitoring of line and path performance
• Economical access to T3/E3 Frame Relay services
• 5-year manufacturer's warranty

Flexible Data Transport

The DataSMART T3/E3 IDSU includes selectable HSSI (High Speed Serial Interface) and V.35/EIA-530/X.21 data ports. These interfaces allow you to connect a variety of data and video equipment to your network. For maximum flexibility, these data ports support full T3/E3 bandwidth and variable clock rates in Nx.5 Mbps increments. In multi-rate mode, the V.35 port supports rates up to 8M, while the HSSI port supports rates up to 35M (T3) and 24M (E3). The clock rates can also be set at different rates in transmit and receive directions. Variable clock rates allow carriers to offer high-speed, variable-rate Frame Relay access more economically than T3/E3 services. The DataSMART IDSU also protects your equipment investment. You can use the V.35 port with your router today, and upgrade your router to HSSI when your bandwidth requirements change. These upgrades can be accomplished via software commands, and without upgrading your access equipment.

Easy Diagnostics

Front-panel LEDs on the DataSMART IDSU indicate network and DTE interface status, system status, alarm conditions and loopbacks. The DataSMART IDSU includes a loopback activation switch and front-panel monitor jacks. These features assist in fault isolation and allow for non-intrusive monitoring of the network. All standard T3 and E3 alarms are monitored, including signal, sync loss, and remote alarm conditions. The IDSU will also send both alarm occurrence and clear messages to a network management station.

Advanced Network Management

The DataSMART IDSU provides a wide range of network management capabilities. Its embedded SNMP agent supports standard MIBs, SNMP Traps, TELNET and Pings. In addition, all the IDSU functions can be easily managed via direct or dial-up access to the RS232 control port. When alarm conditions occur, the DataSMART IDSU can notify you in a variety of ways. It can be configured to send Trap messages to an SNMP host, toggle an alarm relay, send RS232 messages, even dial out over a modem.
