3 3 . . 0 0 C C O O N N F F I I G G U U R R A A T T I I O O N N The Model 1094A is equipped with three sets of eight DIP switch- es, which allow configuration of the unit for a wide variety of applica- tions. This section describes switch locations and explains all possible configurations. 3.1 CONFIGURING THE HARDW ARE DIP SWITCHES The 24 external [...]

7 Switches S2-6 and S2-7: Clock Mode Use Switches S2-6 and S2-7 to configure the 1094A for internal, external, or receive recover clock mode. Switch S2-8: Enable/Disable Loop T ests from DTE Use Switch S2-8 to allow Model 1094A to enter loopback tests when the DTE raises the appropriate loop request pin. S2-8 Setting On Response to DTE Loopback Req[...]

11 4.2 CONNECTING THE SERIAL PORT The serial port interface on the Model 1094A uses interchange- able QuikConnect™ Modules. Each QuikConnect™ Module has a 50-pin card edge connector on one side and a serial port interface on the other . Figure 4 below shows how a QuikConnect™ Module plugs into the back of the Model 1094A. 4.2.1 Changing QuikC[...]

4.2.4 Configuring the X.21 QuikConnect™ Module The serial port on the X.21 QuikConnect™ Module is default wired as a DCE, but may be switched to a DTE. This is done by reversing the orientation of the DCE/DTE strap, as described below: T o reverse DCE/DTE orientation, remove the module according to the instructions in Section 4.2.1 . The DCE/DT[...]

5 5 . . 0 0 O O P P E E R R A A T T I I O O N N Once the Model 1094A is properly configured and installed, it should operate transparently . This sections describes power-up, read- ing the LED status monitors, and using the built-in loopback test modes. 5.1 POWER-UP T o apply power to the Model 1094A, first be sure that you have read Section 4.3 , [...]

Framer The framer is used to determine the status of the line. In normal operation the framer trans- mits and expects to receive framed packets from the far end. If the framer receives framed packets from the far end, CTS and CD will be active. If framed packets are not received, CTS and CD will be inactive. The restart procedure uses this informat[...]

5.3.2 Loops and Patterns The following section describes the T est Modes used in the Model 1094A. At the bottom of each T est Mode, a figure is included to show the data path. Local Loop There are two different modes of operation for a Local Loop depending on the status of the units at the time that the Local Loop is initiated. If the units are not[...]

Local Loop After the 51 1/51 1E pattern times out, the ER led with 51 1/51 1E will begin flashing. It will remain this way until (continued) the pattern generator switch is turned off. Note that the data at the local DTE and the remote DTE are not valid. Because the data is unframed there is no way for the framer to send this data out to the DTE. T[...]

Remote Digital The Remote Digital Loop with 51 1/51 1E is Loop with shown above. After RDL is established the 51 1/51 1E Remote units' Restart T imer is set to one minute. This has been done because when the 51 1/51 1E generator is started on the local unit, the Remote framer begins seeing unframed packets. The Remote unit can not distinguish [...]

5.3.3 Using the V .52 (BER) T est Pattern Generator T o use the V .52 BER tests in conjunction with the Remote Digital Loopback tests (or with Local Line Loopback tests), follow these instructions: 1. Locate the “51 1/51 1E” toggle switch on the front panel of the 1094A and move it UP . This activates the V .52 BER test mode and transmits a “[...]
