3.0 CONFIGURATION The Model 1088 is equipped with two sets of eight DIP switches, which allow configuration of the unit for a wide variety of applications. This section describes switch locations and explains all possible configurations. 3.1 CONFIGURING THE HARDWARE DIP SWITCHES The 16 external switches are grouped into two eight-switch sets, and are externally accessible from the underside of the Model 1088 (See Figure 1). Front 8 7 6 5 4 3 2 1 S3 8 7 6 5 4 3 2 1 S2 Off On Back Figure 1.
Configuration DIP Switch Set “S2” Switches S1-1 through S1-8 may be used to configure CO/CP operation, line framing and coding, CRC-4 operation, and DTE initiated loop diagnostics. Default settings of S1 switches are shown in Table 1.
1088/C ignores DTE loop requests. In the Off position, loop requests may still be initiated by the front panel switch.

The following table summarizes default positions of DIP Switch S3. Detailed descriptions of each switch follow the table.

When the CO and CP units connect over DSL, the CP will enter a predefined default configuration (Receive Recovered Clocking). During the negotiation process between the units, the CO unit will configure the DTE rate/line rate on the CP unit as defined by the settings of the CO unit. When additional bandwidth is required, only the configuration of the CO unit should be changed. This feature gives ISPs, LECs and PTTs the ability to provision bandwidth on an as-needed basis to customers.
4.0 INSTALLATION Once the Model 1088 is properly configured, it is ready to connect to the twisted pair interface, to the serial port, and to the power source. This section tells you how to make these connections. 4.1 CONNECTING THE TWISTED PAIR INTERFACE The Model 1088 supports communication between two DTE devices at distances to 5 miles (8 km) over 24 AWG (.5 mm) twisted pair wire. Two things are essential: 1. These units work in pairs.
V.35 straight through cable (See Figure 5). Appendix C describes pin assignments and signal sources for the Model 1088/C V.35 interface. When purchasing or constructing an interface cable, please refer to the pin diagrams in Appendix C as a guide.

such as a router. However, the X.21 interface on the Model 1088/D may be configured as DTE (Data Terminal Equipment) for connection to DCE such as a modem or multiplexer. When connecting the X.21 interface of the Model 1088/C to your DTE device, use a X.21 straight through cable (See Figure 7). DSL Span Remote Model 1088) Straight-Through 15-pin D-Sub Cable Router (DTE) OR Mux (DCE) Model 1088/D (DCE or DTE) Figure 7. Connecting the Model 1088/D to X.
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 port (for example, if the DCE arrows are pointing toward the DB-15 connector, the X.21 port is wired as a DCE). Change the DCE/DTE orientation by pulling the strap out of its socket, rotating it 180º, then plugging the strap back into the socket.
120 VAC Power (US) The 100–132 VAC adapter supplied with the U.S. version of the Model 1088 is a wall mount type and may be plugged into any approved 120 VAC wall jack. 230 VAC Power (International) The 230 VAC adapter supplied with the International version of the Model 1088 is a wall mount type and may be plugged into any approved 230 VAC wall jack. DC Power The 36-60 VDC DC to DC adapter is supplied with the DC version of the Model 1088.
5.0 OPERATION Once the Model 1088 is properly configured and installed, it should operate transparently. This sections describes power-up, reading the LED status monitors, and using the built-in loopback test modes. 5.1 POWER-UP To apply power to the Model 1088, first be sure that you have read section 4.4, “Connecting Power” on page 16, and that the unit is connected to the appropriate power source. Then power-up the unit. 5.

The unit can be placed in test mode by the local user or by the remote user. The TM LED will flash for 400msec when a valid packet is received from the Model 1001MC.
Overview Figure 13 shows the major elements used in the loop-back and pattern tests available in the Model 1088. Each block has several functions. Following Figure 13 are descriptions that show how the elements are used during Test Modes. Framer Pattern Gen/Det Loop Control Line Processor Loop Control Pattern Gen/Det Framer Processor Figure 13.

lish a connection after the framer begins seeing unframed packets. The Test Model Timing Chart below shows the amount of time the framer must see consecutive unframed packets before the unit will restart and try to establish a new line connection. The reason that there are different Restart Times will become apparent after reading the rest of the document. The 511/511E Time Out shown refers to the amount of time the 511/511E pattern will be valid.
5.4 LOOPS AND PATTERNS The following section describes the Test Modes used in the Model 1088. At the bottom of each Test Mode, a figure is included to show the data path..

data presented at the far end DTE will be transmitted to the local DTE and then looped back within the local DTE Loop Control block 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.

DTE are not valid. Because the data is unframed there is no way for the framer to send this data out to the DTE. This is an important distinction because other Patton 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 unavailable for transmission. As can be seen from Figure 11, the 511/511E pattern generator has no data path connections available. The 511/511E pattern generator is still available on the remote unit.

This has been done because when the 511/511E generator is started on the local unit, the Remote framer begins seeing unframed packets.

Both framers are now receiving unframed data and will restart after one minute. The 511/511E pattern generators will TimeOut after 45 seconds re-enabling the normal data path.
