  • Page 5: General Information

    GENERAL INFORMATION Thank you for purchasing this GDI Communications LLC. product. The XC-RP300 repeater is an ideal way to extend a VDSL connection and add Ethernet access. No special wiring or networking knowledge required. The XC-RP300 allows you to connect LANs over more than 12,000 feet of inexpensive, twisted copper pair wire, thereby breaking the 300 foot Ethernet distance barrier.

  • Page 6: Applications

    APPLICATIONS The GDI Communications XC-RP300 provides high-speed Ethernet connection between LANs, remote PC’s or any other network enabled 10/100BaseT/TX device. Typical point-to-point operation consists of an XC-LT300 located at one end of the LAN extension and an XC-NT300 located at the other end. Data is passed transparently such that the remote LAN appears to be co-located with the local network.

  • Page 7: Installation

    INSTALLATION Since basic XC-RP300 setup requires no configuration, it can be installed and made operational quickly. Installation takes place as follows: 1. Connect the VDSL line interface between the units (refer to section titled, “Connecting the VDSL Line Interface” on page 4). See Figure 3 for rear panel connector arrangements. 2.

  • Page 8: Connecting To The Vdsl Line Interface

    TESTING NOTE: The XC-RP300 can be bench tested by connecting the Primary VDSL port to the Secondary VDSL port using at least 100 feet of telephone cable. An attenuator can be used in place of the 100 foot cable. Contact GDI Communications for availability. Figure 4.

  • Page 9: Connecting The Switch (Ethernet) Interface

    CONNECTING THE SWITCH (ETHERNET) INTERFACE There are three RJ-45 ports on the front of the XC-RP300 labeled “Switch”. These are 10/100BaseT/TX Ethernet interfaces. These ports are designed to connect directly to a 10/100BaseT/TX network. The interface has the ability to detect whether the connection is DCE or DTE and will automatically configure the interface to support the connected equipment.

  • Page 10: Connecting The Telephone (Pots/Isdn) Line

    CONNECTING THE TELEPHONE (POTS/ISDN) LINE The RJ 11 port labeled “PHONE” is the TELEPHONE or POTS/ISDN interface. A telephone or an ISDN device may be connected to this port and carried over the VDSL line. The XC-RP300 does not need to be powered up for the POTS interface to work. The RJ 11 connector in the XC- RP300 PHONE interface is wired as shown in Figure 7.

  • Page 11: Connecting To Management Console

    DIN connector to a typical 9-pin serial port connector on a PC. Figure 9 shows the pin assignments for the console connector. The converter cable is described in figure 10. Contact GDI Communications for availability. The small switch located next to the console connector allows the user to connect to either the Primary (PRI) or the Secondary (SEC) management port.

  • Page 16: Management Interface

    MANAGEMENT INTERFACE The 10BaseS Manager provides a comfortable graphical user interface (GUI) to the registers of 10BaseS chipset. The GUI enables the user to change the configuration features as well as to monitor the status of the VDSL modems. It supports access of the remote modem via the VDSL Operating Channel (VOC) making configuration very easy.
  • Page 17 VOC channel access The remote modem can be accessed via the VDSL operating channel (VOC). Therefore, the VDSL Manager User’s Manual has special VOC registers, which have to be used. The VOC protocol consists of following steps: 1. Check MS_TXCMD register. The MS_TXCMD register has to equal zero, which indicates that the internal processor is ready for a new VOC operation.

  • Page 18: Management Software Description

    MANAGEMENT SOFTWARE DESCRIPTION Start-up Dialog When the Manager starts, the COM select dialog box appears. The user has to select the COM port that is connected to the VDSL modem. If the SAVE AS DEFAULT check box is checked, the settings are stored and will be available on the next start-up.
