8 3.0 PPP OPERATIONAL BACKGR OUND PPP is a protocol used f or multi-ple x ed transport over a point-to-point link. PPP operates on all full duplex media, and is a symmetric peer-to- peer protocol, which can be broken into three main components: • A standard method to encapsulate datagrams o v er serial links • A Link Control Protocol (LCP) to e[...]

9 Figure 2. Cisco router with serial interface, con fi gured as PPP Half-Bridge Figure 2 shows a typical Cisco router with a serial interf ace con fi gured as a PPP Half Bridge. The router serial interface uses a remote de vice that suppor ts PPP bridging to function as a node on the remote Ether net network. The serial interface on the Cisco wil[...]

10 Figure 3. T ransparent bridging between two routers over a serial interf ace Figure 3 illustrates transparent bridging between two routers o v er a serial interface (s0). Bridging will occur between the two Ethernet inter- f aces on router A (e0 and e1) and the two Ethernet interfaces on router B (e0 and e1).[...]

11 4.0 CONFIGURATION The Model 1082/I and Model 1082/144/I each are equipped with 16 DIP s witches that enable con fi gur ation of the unit f or a wide variety of appli- cations. This section descr ibes switch locations and e xplains the different con fi gurations. 4.1 CONFIGURING THE HAR DWAR E DIP SWITCHES Using a small fl at-tip screwdriv er [...]

12 Figure 5. DIP switches S2 and S2 Figure 5 shows the orientation of the DIP s witches in the “ ON ” and “ OFF ” positions. Configuring DIP Switch S1 DIP s witch S1 is where you con fi gure the data r ate, asynchronous or synchronous data f ormat, transmit clock source, and response to RDL request. The f ollowing tab le summarizes def au[...]

13 Note When setting the 1082 for SNMP Management, the DTE r ate switches (S1-1,S1-2, and S2-1) m ust be also set to the ON posi- tion. Theref ore, to set a 1082 unit SNMP Mangagement mode, the follo wing s witches hav e to be at the ON position, S1-1, S1-2, S2-1. Switches S1-1 and S1-2: Data Rate Use s witches S1-1 and S1-2 to con fi gure the asy[...]

14 Switches S1-6 and S1-7: System Clock Mode Use Switches S1-6 and S1-7 to con fi gure the 1082/I or Model 1082/144/ I f or internal, or receive recov er cloc k mode. Switch S1-8: Response to RDL Request Use Switch S1-8 to allow Model 1082/I and Model 1082/144/I to enter the Remote Digital Loopback diagnostic test when requested to do so b y the f[...]

15 Con fi guring DIP switch “ S2 ” Use the eight DIP s witches in S2 to enable 19.2 kbps or 144* kbps syn- chronous operation and set the loopbac k modes. The following tab le summarizes def ault positions of DIP s witches S2-1 through S2-8. Detailed descriptions of each switch f ollo w the table . Switches S2-1: 19.2 kbps or 144 * kbps Synchr[...]

17 5.0 INSTALLATION When the Model 1082 has been properly con fi gured, it may be con- nected to the DSL twisted pair interf ace, the 10Base-T Ethernet Inter- f ace, and the po wer source. This section describes these connections. Figure 6. Model 1082/I or Model 1082/144/I rear view 5.1 CONNECTING DSL INTERFACE The Model 1082 suppor ts communicati[...]

18 The RJ-45 connector on the Model 1082 ’ s twisted pair interface is polar- ity insensitive and is wired f or a two-wire interface . The signal/pin rela- tionships are shown in Figure 7 belo w .

19 5.4 POWER CONNECTION Universal A C Po wer (100 – 240V AC) The Model 1082/I uses a 5VDC , 2A universal input 100 – 240V AC , power supply (center pin is +5V). The univ ersal input power supply has a male IEC-320 power entry connector . This power supply connects to the Model 1082/I by means of a barrel jac k on the rear panel. Many interna- t[...]

20 DC P ower The DC adapter supplied with the DC version of the model 1082/I plugs in a DC source (nominal 48VDC) and plugs into the barrel power supply jac k on the rear of the 1082/I. Refer to Figure 10 below to mak e the proper connection. Figure 10. P ow er adapter W ARNING There are no user -serviceable parts in the power supply section of the[...]
