    Figure 2 shows the orientation of the DIP switches with respect to the “ON” and “OFF” positions. Front Panel Figure 2. Close up of the configuration switches NOTE: The ON position is oriented toward the front of the Model 2715RC.
  • Page 7 DIP Switches S1 - S8 The configuration switches on S1 - S8 may be set to allow config- uration for a wide range of applications. Default settings of S1 through S8 are shown in the table below. Descriptions of each switch follow the table.
  • Page 8 MF. Otherwise, the one using CRC-4 MF will detect loss of sync. In unframed mode, SW3 is used along with SW4 to determine the clock mode. In unframed mode, the model 2715RC can be set to Network, internal, or external clock mode.

  • Page 9: Clock Modes

    External Clock Transmitter timing is derived from the local DTE device. Note: When using the 2715RC as a high-speed short range modem, one unit of the link must be configured in either internal or external clock, and the other end must be configured for network clock mode.
  • Page 10 NOTE: When the data rate is set to 2.048Mb/s, then the unit is in G.703 mode, and it transmits user data on all 32 timeslots. There is no framing information; therefore, the CAS MF (SW2) is ignored and SW3 defaulted to clock mode. In all other rate settings, the unit employs G.704 framing;...

    Model 2715RC when its card-edge connector makes contact with the chassis’ mid-plane socket, and when the chas- sis’ power supply is turned on. Note: The Model 2715RC is a “hot swappable” card—it will not be damaged by plugging it in or removing it while the rack is powered up.
  • Page 16 The Loss of Sync LED lights when the unit loses synchronization with the incoming signal. This may happen when there is a framing mismatch or a loss of signal. In unframed mode, the LOS LED monitors the status of the transmit clock. The alarm LED indicates the presence of a AIS or RAI, or Out of Frame condition.
  • Page 17 The Local Loopback (LL) test checks the operation of the local Model 2715RC, and is performed separately on each unit. Any data sent to the local Model 2715RC in this test mode will be echoed (returned) back to the user device (i.e., characters typed on the key- board of a terminal will appear on the terminal screen).
  • Page 18 5.4 BIT ERROR RATE (V.52) DIAGNOSTICS The Model 2715RC offers a QRSS V.52 Bit Error Rate (BER) test pattern. This test pattern may be invoked along with the LAL and RDL tests to evaluate the unit(s) and the communication links.
