    Introduction Chapter 1 PRODUCT OVERVIEW The T3SU 300 is a multiport DSU/CSU (data service unit/channel service unit) that provides access to T3 services. The unit provides a cost-effective, versatile approach for migrating T1 services to T3. The TDM (time division multiplexer) multiport design allows you to share the cost of a T3 line between multiple applications.

  • Page 16: T3 Overview

    This connection can be made via ethernet, a local EIA-232 link, or through the built-in V.34 modem. Advanced dial-out on trap capabilities through the built-in modem allow the T3SU 300 to contact remote hosts and alert them to DSX-3 network conditions (without dedicated management connections).

  • Page 17: Telnet

    TELNET TELNET provides a password-protected, remote login facility to the T3SU 300 that allows a remote user to control the T3SU 300 through the terminal menus. Only one TELNET session may be active at a time.

  • Page 18: Hssi Card

    Quad DSX-1 Card The optional Quad DSX-1 interface card plugs into the card slots on the rear of the T3SU 300. This card allows you to transport up to four DSX-1 lines per card over the DS3 interface of the T3SU 300 along with high-speed data from the other HSSI/V.35 ports.
  • Page 19 T3SU 300 DTE port card slots. Even though the Quad DSX-1 interface card allows you to transport T1 information, the T3SU 300 still operates the DS3 interface in an unchan- nelized fashion. Therefore, your DS3 network provider must supply you with an unchannelized, point-to-point DS3.

    44.2 Mbps data over unchannelized T3 circuits. In the application shown in Figure 7-1, the T3SU 300 provides network connectivity for a router running at 44.2 Mbps. The data is frame relay and the unit is SNMP-managed via the local ethernet.

  • Page 92: Point-To-Point Multiport Application

    When networking requirements call for sharing the bandwidth of a point-to-point T3 circuit, additional data ports can be installed into the T3SU 300 for multiport operation. The T3SU 300 supports up to three port option cards (Quad DSX-1, V.35 or HSSI). These option cards are hot swappable and can be field installed.

    (using the HSSI ports), as well as the V.35 data connection requirements of the video conferencing unit and the main frame. The bandwidth is split by the T3SU 300 to provide 18 Mbps for each router, 1.5 Mbps for the video conference units, and 6 Mbps for the main frames.

  • Page 94: Fractional T3 Carrier Application

    FRACTIONAL T3 CARRIER APPLICATION When network providers want to provide service at rates less than full T3, T3SU 300 units can be used in pairs for deploying sub-T3 rate services. In this application example (shown in Figure 7-3), a carrier provides fractional T3 access at 8 Mbps for internet connectivity.
