Patton Electronics' technical staff is also available to answer any ques- tions that might arise concerning the installation or use of your Model 2073RC. Technical Service hours: 8 AM to 5 PM EST (8:00 to 17:00 UTC-5), Monday through Friday.
X.21 or ethernet device to communicate bi-directionally over the G.703 co- directional PCM network. Supporting internal, external DTE timing or G.703 network generated timing, the Model 2073RC is perfect for network- ing applications that require speeds of 64 kbps. The modular rear cards...
This section describes all possible hardware switch configuration. Figure 1 shows the location of the DIP switches on the top of the printed circuit board Figure 1. Model 2073RC top view showing location of DIP switches Figure 2 shows the orientation of the DIP switches with respect to ON/ OFF positions.
3.1 CONFIGURING THE FRONT INTERFACE CARD Switches SW3-2 and SW3-1: Clocking Mode Use Switch SW3 to set the system clock for the Model 2073RC. When using two Model 2073RC together in a point-to-point application as short range modems, set one unit for either Internal or External transmit clock and the other unit to Network clock.
Switch SW3-4 Response to Remote digital (RDL) Loopback Use Switch SW3-4 to enable or disable response to Remote digital Loop- back by the local 2073RC when a RDL request is sent by a remote device. SW3-4 Switch SW3-3 Terminal (DTE) data sampled using the 2073RC Transmit clock or External Clock (provided by V.35 DTEs only)
3.2 CONFIGURING THE REAR INTERFACE CARD Your Model 2073RC comes with one of the following rear cards: • The Model 1001RCM13448C (M/34/ RJ-48C) • The Model 1001RCM11548C (DB-15/RJ-48C) • The Model IM2RC/IA (RJ-45/10Base-T RJ-48C) Each of these options supports one DTE interface connection and one 4- wire line connection.

Figure 4. Orientation of Interface Card Straps The following sections describe the strap locations and possible settings for each rear card.
Model 1001RCM13448C Strap Settings Figure 5 shows the strap location for the Model 1001RCM13448C (M/34) rear card. This strap determines whether Signal Ground and Frame Ground will be connected. Figure 5. 1001RCM13448C strap locations. Table 1 provides an overview of interface strap functions for the rear interface cards.

Note If the 2073RC is being used for private short-range modem applications, the twisted-pair cable connected to its port will need to be a cross-over cable.
This section describes the functions of the Model 1001R14 rack chassis, tells how to install front and rear Model 2073RC Series cards into the chassis, and how to connect to the twisted pair interface and the serial interface. 4.1 THE MODEL 1001R14 RACK CHASSIS The Model 1001R14 Rack Chassis (see Figure 10) has 14 or 16 device card slots, plus a single power supply or dual redundant power supplies.
4.2 INSTALLING THE MODEL 2073RC INTO THE CHASSIS The Model 2073RC is comprised of a front card and a rear card. The two cards meet inside the rack chassis and plug into each other by way of mating 50 pin card edge connectors. Use the following steps as a guide- line for installing each Model 2073RC into the rack chassis: 1.
RJ-48C (see Figure 11). Figure 11. NetLink-E1 twisted-pair interface Note If the 2073RC is being used for private short-range modem applications, the twisted-pair cable connected to its port will need to be a cross-over cable. 1 RX data (TIP)
Once the 2073RC is installed and configured properly it is ready to place into operation.This section describes the function of the LED indicators, and the use of the loopback and pattern test modes. 5.1 LED DESCRIPTIONS The 2073RC is equipped with 12 LED indicators that monitor the status of communication.
To perform a LL test, follow these steps: 1. The Local Loop can be initiated from the 2073RC unit either by acti- vating the LL signal on the DTE (if you are not sure which lead is the RDL signal, please refer to the Appendix,) or by toggling the top front panel switch towards the label “LLB”.
The Remote Digital Loopback (RDL) test checks the performance of both the local and remote 2073RC as well as a point-to-pointcommunication link between them. Any characters sent to the remote 2073RC in this test mode will be returned back to the originating device (i.e,characters typed on the keyboard of the local terminal will appear on the local terminal screen after having been passed to the remote 2073RC and looped back).
