TESTING THE SYSTEM 7 The Fractional Interface Card supports a complete set of loopback functions that allow you to test the data communication path between the host equipment, the Campus unit, and the remote unit. You can use the LCD and menu buttons or an ASCII terminal to initiate loopback tests. To initiate a loopback from the LCD, see “Configuring Loopbacks” on page 4-20. To use an ASCII terminal to initiate a loopback, see “Configuring Loopbacks” on page 5-28.
Testing the System The following figure shows the Local to Local (1) and Remote to Local (2) loopbacks. Remote Unit B Local Unit A Data Port HDSL 1 Data Port 2 The following figure shows the Remote to Remote (3) and Local to Remote (4) loopbacks. Remote Unit B Local Unit A Data Port 4 HDSL 3 Data Port The following sections describe each type of loopback. Local to Local Loopback The Local to Local loopback tests the local data port and a small portion of the Fractional Interface Card.
Testing the System Remote to Local Interface The Remote to Local loopback tests the local data port, the entire data path inside the local Campus unit, the HDSL line, the HDSL transceivers of both units, and most of the internal data path inside the remote unit. Use this loopback to verify that the HDSL line is operational, and that the HDSL transceiver of the remote unit is operational. This loopback also tests the same areas as the Local to Local and Local HDSL loopbacks.
Testing the System CANCELLING LOOPBACKS There are two ways to cancel a loopback test: • cancel the loopback manually • set the Loopback Timeout option to cancel the loopback after a set period of time Cancelling Loopbacks Manually You can cancel a loopback from either the LCD or an ASCII terminal. To use the LCD, see “Configuring Loopbacks” on page 4-20. See “Configuring Loopbacks” on page 5-28 to use an ASCII terminal.
Testing the System V.54 Loopback Support The Fractional Interface Card supports V.54-compliant loopbacks, which enable initiation of loopback tests from a V.54-capable host device. Before you can use V.54 loopbacks, you must enable V.54 loopback support. To enable V.54 loopback support through the LCD menu, see “Enabling V.54 Loopback Support” on page 4-22. See “Enabling V.54 Loopback Support” on page 5-31 to enable V.54 loopback support through an ASCII terminal. The V.

TIMING AND CLOCK OVERVIEW 8 This chapter describes different issues in determining the correct settings for Campus-RS Fractional Interface Card clock and timing source options. TIMING SOURCE For normal operation, communications networks normally require that communicating elements be separated into data circuit-terminating equipment (DCE) and data terminal equipment (DTE). DCEs normally provide timing information for the DTEs.
Timing and Clock Overview Standard Timing Configuration In this configuration, the internal oscillator of one unit is used as a frequency reference for all clocks in the system. Since the Fractional Interface Cards are designed as DCE, they are expected to provide both Serial Clock Transmit (SCT) and Serial Clock Receive (SCR) output signals. Within a Campus system, set the Timing Source option for one of the Fractional Interface Cards to HDSL timing, as shown in the following figure.
Timing and Clock Overview Port Timing Configuration If one of the Fractional Interface Cards needs to accept primary timing from the connected host equipment, set its Timing Source option to Port timing. Set the Timing Source option for any connected Campus units to HDSL timing. The TT input of the “Port-timed” unit is used as a frequency reference for all clocks in the system, as shown in the figure below. A phase lock loop (PLL) keeps the Campus system in phase with the host timing.
Timing and Clock Overview The SCT signal on the Fractional Interface Cards cannot be configured as an input. Also, in a standard DCE host, the SCT signal is also an output. There are two critical implications for the configuration shown in the figure above: • The Fractional Interface Card accepts only one clock input (TT), this clock is assumed to provide a timing reference for both the transmit and receive data paths.
Timing and Clock Overview Data Cable Campus Desktop or Line Unit Host Equipment SCR RD SCT TT SD HDSL Internal or HDSL Timing To circumvent this potential problem, set the Transmit Clock option on the Fractional Interface Card to External, so that the transmit clock is taken from the TT input instead of the SCT output. With this approach, the TT and SD signals experience the same delay as they propagate through the data cable, and remain synchronized to each other.
