7 3.0 CONFIGURATION The Model 1088 is equipped with two sets of eight DIP s witches, which allow configuration of the unit f or a wide v ariety of applications. This section describes switch locations and e xplains all possib le configur ations . 3.1 CONFIGURING THE HAR DWARE DIP SWITCHES The 16 e xternal switches are grouped into tw o eight-s wi[...]

8 Configuration DIP Switch Set “S2” Switches S1-1 through S1-8 ma y be used to configure CO/CP operation, line framing and coding, CRC-4 operation, and DTE initiated loop diag- nostics. Default settings of S1 s witches are shown in T able 1. T able 1: S2 Summary T able Switch S2-1, S2-2, S2-3, S2-4, and S-5. Reser ved f or factory use and mus[...]

9 1088/C ignores DTE loop requests. In the Off position, loop requests ma y still be initiated by the front panel s witch. Configuration Switch Set “S3” Use the six DIP Switches in Switch S3 to enable the DTE bit r ate. The f ollowing tab le summar izes def ault positions of DIP Switch S3. Detailed descriptions of each switch f ollow the table[...]

10 Note Based on the DTE rate chosen, the Model 1088 will automati- cally select the optimum line rate depending on distance and line conditionsfor the distance . The line selection will be based on the lowest line r ate that will suppor t the DTE rate. Switch S3-7: Reset Software Defaults. Switch S3-7 allows the user to reset the software configu[...]

11 Switch S3-8: T ransmit Data (TD) Sampling Point. Switch 3-8 controls the T ransmit Data (TD) sampling point. 3.2 NETLINK PLUG-AND-PLAY The NetLink Plug-and-Pla y f eature allows ISPs , carriers and PTTs to quickly upg rade the link speed f or a customer without requir ing the cus- tomer to re-configure the Customer Premise (CP) Model 1088. This[...]

12 When the CO and CP units connect ov er DSL, the CP will enter a pre- defined def ault configuration (Receiv e Recovered Cloc king). Dur ing the negotiation process between the units, the CO unit will configure the DTE rate/line rate on the CP unit as defined b y the settings of the CO unit. When additional bandwidth is required, only the con[...]

13 4.0 INSTALLATION Once the Model 1088 is properly configured, it is ready to connect to the twisted pair interf ace, to the serial por t, and to the power source . This section tells you ho w to make these connections. 4.1 CONNECTING THE T WISTED PAIR INTERFACE The Model 1088 suppor ts communication between two DTE de vices at distances to 5 mil[...]

When connecting the X.21 interface of the Model 1088/C to your DTE de vice, use a X.21 straight through cab le (See Figure 7). Figure 7. Connecting the Model 1088/D t[...]

16 The DCE/DTE strap is located on the top side of the 1088/D pc board (See Figure 9, below). The arrows on the top of the strap indicate the configuration of the X.21 por t (f or e xample, if the DCE arro ws are point- ing tow ard the DB-15 connector , the X.21 por t is wired as a DCE). Change the DCE/DTE orientation by pulling the strap out of i[...]

23 data presented at the f ar end DTE will be transmitted to the local DTE and then looped back within the local DTE Loop Con- trol bloc k with the Processor . After the Local Loop is deselected, the units will be placed back into DataMode and the normal data paths will be re-established. Figure 16. Block Diagr am Local Loop Mode 1 with 511/511E Fi[...]

24 DTE are not valid. Because the data is unframed there is no wa y for the framer to send this data out to the DTE. This is an impor tant distinction because other P atton units will send out the 511 pattern. When the unit is placed into a Mode 2 Local Loop , the 511/511E pattern generator on the local unit is unav ailable f or transmis- sion. As [...]

After RDL is established the Remote units' Restart Timer is set to one minute. This has been done because when the 511/511E gen- erator is star ted on the local unit, the Remote framer begins seeing unframed p[...]

26 units enable the 511/511E pattern within 4 seconds of each other , both units will be tr ansmitting and receiving the 511/511E pattern. Both framers are now receiving unframed data and will restar t after one minute. The 511/511E pattern generators will TimeOut after 45 seconds re-enabling the normal data path.
