6 2.0 W ARRANTY INFORMATION P atton Electronics warrants all Model 3088 components to be free from def ects, and will—at our option—repair or replace the product should it f ail within one year from the first date of shipment.
7 3.0 GENERAL INFORMATION Thank you f or your purchase of this P atton Electronics product. This product has been thoroughly inspected and tested and is warranted f or One Y ear parts and labor .
8 4.0 CONFIGURATION The Model 3088 (see figure 1) has two configuration modes , DIP s witch and software . Figure 1. Model 3088 (3088/D version sho wn) DIP s witch configuration mode is entered b y starting the unit with the DIP s witches in any position other than all OFF or all ON.
9 The Model 3088 provides the f ollowing parameters f or configur ing the unit. P arameter Description P ossible V alues Default V alue P ass wor d The pass word used to login to the console. Character strings 1–9 characters long. patton Circuit ID The circuit ID used to identify the unit.
10 Clock Mode Controls DSL and serial clock sources. Inter nal clock mode means the 3088 provides its own cloc k to both the ser ial interf ace and the DSL link. External clock mode means the serial interface pro vides the clock used f or the DSL link.
11 4.1 CONFIGURING THE DIP SWITCHES The Model 3088 is equipped with two sets of DIP s witches, which allo w con- figuration of the unit f or a wide v ariety of applications. This section describes s witch locations and e xplains all possib le configur ations.
12 The two sets of DIP s witches on the underside of the Model 3088 are ref erred to as S1 and S2 . As shown in figure 3, the orientation of all DIP s witches is the same with respect to “ON” and “OFF” positions Figure 3. Close-up of configuration s witches (all sets are identical appearance) 4.
13 Configuration Reset to Factory Defaults T o recov er from a forgotten pass word, the user may reset the unit to its f actor y configuration. After seeing the “Reset Mode” message, the user should type the ‘*’ key . This will result in a ‘:’ prompt.

16 Loops The V .35 interface has pins tw o pins, one to request an LAL and the other to request and RDL. If DTE loops are enabled, then when these pins are asser ted, the 3088/C will star t a local loopback or a remote loopback. If DTE loops are disabled, these requests will be ignored.
17 S2-3: Annex A/B Anne x A is typically used in Nor th American-like networks, whereas Anne x B is typically used in European-like netw or ks. The diff erent anne x es specify different PSD (pow er spectral density) masks because of the diff erence in T1 and E1 PSDs.
18 • Circuit ID : The circuit ID communicated to other units via EOC. EOC (Embedded Operations Channel) is an out-of-band channel specified in the G.991.2 standard f or SHDSL. W e use standard EOC messages f or our remote loopback. The 3088 also suppor ts propr ietar y EOC messages that allow a 3096RC to configure it.
19 • FPSW Settings : What the front panel switches are set to (if the unit is populated with them). • Configuration Mode : Whether the 3088 is configured by DIP s witches or software . • DSL Link State : In Progress, Success , Deactivated, or Idle.
20 Help Commands The f ollowing commands are pro vided to help the user find the correct command: • help: Lists all the commands that the console recognizes . • system help: Lists all the commands that star t with system that the console recognizes .
21 • system set cloc kmode <internal|external|receiverecover>: Sets the clock mode . Inter nal clock mode means the 3088 provides the clock to both the DSL and the serial interf ace. Exter nal clock mode means the 3088 uses the serial transmit clock as its DSL transmit clock (V .
22 • system show leds: Shows the current state of all softw are controlled LEDs. • system show fps w : Shows the current front panel s witch settings. DSL Configuration Commands The f ollowing commands are used to configure the DSL: • dsl set annex <a|b>: Set the anne x.
23 • dsl set errmon startdelay <startdelay>: Sets the number of seconds to wait after the DSL link comes up bef ore the error monitor star ts inspecting inter vals . The f ollowing commands displa y the current DSL configuration: • dsl show anne x: Shows the currently selected G.
24 • dsl show syncstate : Shows the sync state of the DSL link: out of sync, acquiring sync, in sync , or losing sync • dsl show linkspeed : Shows the actual DSL data rate (minus DSL ov erhead) • dsl show linecond : Shows the line condition: good or poor • dsl show nmr : Shows the noise margin ratio .
25 The dsl clear err cntrs command clears the error counters. Remote Console Provided that there is a DSL link to a second 3088, a user ma y login to the first 3088’ s console and enter the remote console command to access the second 3088’ s console.

27 F ollow the instructions below to activ ate RocketLink Plug ‘n’ Play between CO (Model 3096RC and CP (Model 3088) units: • Set the Model 3096RC (CO) to either Internal or Exter nal clocking mode as defined by the application.
28 5.0 INSTALLATION Once the Model 3088 is properly configured, it is ready to connect to the twisted pair interf ace, to the serial por t, and to the power source .
29 The RJ-45 connector on the Model 3088’ s twisted pair interface is polar- ity insensitive and is wired f or a two-wire interf ace. The signal/pin rela- tionships are shown in figure 5. Figure 5. Model 3088 V .35/X.21 interfaces. 5.2 CONNECTING THE MODEL 3088/CA (V .
30 Connecting the Model 3088/CA (V .35) to a “DCE” Device The Model 3088/CA provides a V .35 DCE (data circuit ter minating equip- ment) interf ace on an DB-25 f emale connector. As a DCE, this interface is designed to connect to DTE equipment, such as a router .
31 ment ) f or connection to DCE such as a modem or multiple xer . When connecting the X.21 interf ace of the Model 3088/D to your DTE or DCE de vice, use an X.
32 The DCE/DTE strap is located on the top side of the 3088/D pc board (See figure 10, below). The arrows on the top of the strap indicate the configuration of the X.21 por t (f or example, if the DCE arro ws are point- ing tow ard the DB-15 connector , the X.
33 6.0 OPERATION Once the Model 3088 is properly configured and installed, it should oper- ate transparently . This sections descr ibes power-up , reading the LED status monitors, and using the b uilt-in loopback test modes. 6.1 P OWER-UP T o apply power to the Model 3088, first be sure that y ou hav e read sec- tion 5.

35 . Figure 13. Local Analog Loopback diagram The data received from the serial interf ace is looped back bef ore going out on the DSL line. Note that this loopback occurs after the pattern gen- erator/BER meter . This means that running a 511 pattern is conjunction with an LAL should result in no error detected by the meter .
36 7.0 REMOTE CONSOLE MANUAL INFORMATION The PC user (near-end) ma y configure and verify status of the remote 3088 (f ar-end) via a Remote Console session.
37 — If 3088 (F ar End) already has an activ e remote console session open, you will see the message Console: Remote console con- nection request rejected . This can also happen if the remote 3088 (f ar-end) has an established remote console session with the local 3088 (near-end) which has timed out.
38 Figure 16 is a screenshot of opening a typical remote console session: Figure 16. Opening a typical remote console session How to Disconnect The remote console session ends under any of the f ollowing conditions: • The user enters the command logout • A timeout period of 5 minutes elapses since the user has entered a command to the console.
39 lowing is what is displa y ed upon a user’ s logging out of a remote console session after logging in. > remote console > Console: Remote console connection established. password: ****** > logout Console: Remote console connection lost. > The timeout period is a fixed, non-configurab le parameter of 5 minutes.
