TESTING THE SYSTEM (LOOPBACK TESTS) The Campus-Flex RS 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 either the LCD and menu buttons or an ASCII terminal to initiate loopback tests. To use an LCD to initiate a loopback, see page “Initiating a Loopback Condition” on page 4-27.
Testing the System (Loopback Tests) Remote to Local Loopbacks The Remote to Local loopback tests the selected remote data port, the entire data path inside the local and remote Campus units, the HDSL line, and the HDSL transceiver of both units. Use this loopback to verify that the HDSL line is operational and that the HDSL transceiver of the remote unit is operational. If the remote unit is not a Campus-Flex RS unit, not all the remote loopback options are available.
Testing the System (Loopback Tests) CLEARING LOOPBACKS You can clear a loopback test in the following two ways: • cancel the loopback manually from either the LCD or an ASCII terminal • set the Loopback Timeout option to cancel the loopback automatically after a set period of time Clearing Loopbacks Manually You can clear a loopback from either the LCD or an ASCII terminal. To use the LCD, see page “Clearing a Loopback” on page 4-29.
Testing the System (Loopback Tests) V.54 LOOPBACK SUPPORT The Campus-Flex RS Interface Card supports V.54-compliant loopbacks. This lets you initiate loopback tests from a V.54-capable host device. Before you can use V.54 loopbacks, you must enable V.54 loopback support. To do so through the LCD menu, see page “Enabling or Disabling V.54 Loopback Support” on page 4-30. To do so through an ASCII terminal, see page “Enabling or Disabling V.54 Loopback Support” on page 5-48. The V.
TIMESLOT ASSIGNMENT (CHANNEL MAPPING) The 24 timeslots (channels) of the HDSL link carry voice, data, and/or video signals from all three ports of the Campus-Flex RS Interface Card. You must decide how to allocate the 24 timeslots among the three ports to suit your needs. To map the channels, assign timeslots and ports on the Campus-Flex RS Interface Card to individual HDSL channels. You can assign the 24 timeslots using either straight mapping or cross mapping.
Timeslot Assignment (Channel Mapping) • Channels 20 through 24 on the local Campus-Flex RS Interface Card map to the same channels on the remote card over Data Port 2 to transfer 280 kbps (56 x 5) or 320 kbps (64 x 5), depending on the rate multiplier.
Timeslot Assignment (Channel Mapping) The following illustration shows an example of cross mapping ports: • Channels 1 through 12 on the local DSX-1 port and channels 13 through 19 on the local Data Port 1 all map to channels 1 through 19 on the remote DSX-1 port. • Channels 20 through 24 on the local Data Port 2 map straight to channels 20 through 24 on the remote Data Port 2. For the following two examples, the Insert Framing option must be turned on for both the local and remote units.
Timeslot Assignment (Channel Mapping) The following illustration shows another example of cross mapping ports. Channels 1 through 12 on the local DSX-1 port, channels 13 through 19 on the local Data Port 1, and channels 20 through 24 on the local Data Port 2 all map to the remote DSX-1 port.
Timeslot Assignment (Channel Mapping) The previous illustration is similar to the mapping if the remote unit is not a Campus-Flex RS Interface Card (for example, a DSX-1 or V.35 unit). In that case, all three ports on a Campus-Flex RS Interface Card map to a single remote port. • To use the LCD menus to assign timeslots, see page 3-3. • To use an ASCII terminal to assign timeslots, see page 5-12.

CLOCK AND TIMING SOURCE OPTIONS This chapter discusses the issues that determine the correct settings for the clock and timing source options of the Campus-Flex RS Interface Card. DSX-1 TIMING If the DSX-1 port on a unit is enabled, the Primary Timing Source must be set to DSX-1. This means that if the DSX-1 port is enabled on both the local and remote ports, both units must have the Primary Timing Source set to DSX-1. The DSX-1 ports support independent transmit and receive timing.
Clock and Timing Source Options DATA PORT TIMING The following sections provide guidance for configuring the timing options if only the Data ports are used and the DSX-1 ports on both the local and remote units are disabled. 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.
Clock and Timing Source Options Within a Campus system, set the Timing Source option for one of the Campus-Flex RS Interface Cards to Internal timing. Connect all other Campus-Flex RS Interface Cards to HDSL timing, as shown in the following figure.
Clock and Timing Source Options Port Timing Configuration If one of the Campus-Flex RS 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 following figure. A phase lock loop (PLL) keeps the Campus system in phase with the host timing.
Clock and Timing Source Options Host Equipment as DCE Primary Timing Cross-Over Data Cable TT SD SCT NC SCR RD NC Campus Desktop or Line Unit as DTE SCR RD SCT TT SD HDSL Port Timing The Serial Clock Transmit (SCT) signal on the Campus-Flex RS Interface Card cannot be configured as an input. In a standard DCE host, the SCT signal is also an output.
Clock and Timing Source Options Transmit Clock Option Set the Transmit Clock option only if the Timing Source is set to either Internal or HDSL. When the Timing Source option is set to Port timing, the Transmit Clock option does not need to be set because TT is equivalent to SCT. The Transmit Clock option can be set to either External or Internal. It determines how the SD signal is sampled. If the Transmit Clock option is set to External, the SD is sampled based upon the clock transitions on the TT input.
Clock and Timing Source Options When the Timing Source is set to either Internal or HDSL, the Campus-Flex RS Interface Card uses the SCT signal to establish the frequency of the transmit data path. The SCT signal does not necessarily indicate exactly where the transitions on SD should occur. SD typically has a constant phase delay from SCT. The TT signal, on the other hand, indicates the exact location of the binary transitions on SD. Any phase delay from the SCT output to the TT input must be constant.
