This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modification.
Packages received without an RMA number will not be accepted. If you have questions about installing or using your Model 1082/F, con- tact technical support at: +1 (301) 975-1007. Technical support is avail- able from 8 AM to 5 PM EST (8:00 to 17:00 UTC-5), Monday through...
• CE marked 2.2 DESCRIPTION The Patton Model 1082/F is a high speed, AC powered short range modem that is able to convert data from a 64K G.703 network and trans- mit it at extended distances via 2 wire (single twisted pair) DSL. The G.703 network provides a 64K co-directional three level signal using...
(without byte integrity preservation) over the modem link. The 1082/F is capable of handling either network timing or modem timing, thereby realizing network extension or network replacement con- figurations. Clock jitter is attenuated according to G.823. The Model 1082 is capable of point-to-point distances up to 5 miles using 24 AWG wire.
Applications and Associated Timing There are two typical applications that result in two different timing modes for the G.703 interface. These are described in the following sections. Timing of Application 1: Network Loop Extension. In this application, the network supplies the timing for the entire system. The first G.703 recovers the timing.
The first G.703 interface is in Network Timed mode. The second is in Recover Clock mode. See Figure 2. G.703 G.703 NETWORK G.703 INTERFACE Figure 2. Network Loop Extension Configuration Timing of Application 2: Network Replacement. The first modem uses an internal timing source and supplies the timing for the entire system.
The first G.703 modem is in Internal Clock mode. The second modem is in Receive Recover mode. See Figure 3. G.703 G.703 Figure 3. Network Replacement Configuration 2.5 TIMING MODE SELECTIONS Based on the timing arrangements and clock sources mentioned above, there are two timing modes in which the interface can work.
Octet timing. The Octet timing frame is embedded in the data. Note Octet timing mode is supported only when two 1082/F modems are connected to each other. It is not supported when the 1082/F modem is used with the 1092A or 1092ARC modems from Patton.
The Model 1082/F is equipped with 8 DIP switches that enable configu- ration of the unit for a variety of applications. This section describes switch locations and explains the different configurations. 3.1 CONFIGURING THE HARDWARE DIP SWITCHES Using a small flat-tip screwdriver, remove the protective cover located on the underside of the Model 1082 (see Figure 4).
Figure 5 shows the orientation of the DIP switches in the “ON” and “OFF” positions. Configuring DIP Switch S1 DIP switch S1 is where you configure the units for Octet or clear channel timing, enabling or disabling the front panel switches, SNMP control enable or disable, Clock mode, and RDL enable or disable.
SW1-1 Octet Function. This switch determines whether the modem will be set for clear channel mode or Octet timing. The 1082/F can be used with either another 1082/F, a 1092A/F or a 1092ARC/C/OO modem from Patton. However, when used in Octet timing mode, the 1082/F must be used with another 1082/F.
Placing SW1-6 and SW1-7 in the OFF mode performs reset of the hardware/software. SW1-8 RDL Function. Use Switch S1-8 to allow Model 1082/F to enter the Remote Digital Loopback diagnostic test when requested to do so by the far end Modem. For example, when switch S1-8 is set to “ON”, it will enter RDL mode when requested to do so by the remote Model 1082.

The RJ-45 connector on the Model 1082’s twisted pair interface is polar- ity insensitive and is wired for a two-wire interface. The signal/pin rela- tionships are shown in Figure 7. Figure 7. Model 1082 twisted Pair line interface The RJ-45 connector for connection to the 64 kbps co-directional inter- face is pre-wired according to the signal/pin relationships shown in Figure 8.
Connection of the Patton 1082/F to a CSU DTE requires a crossover twisted pair cable. Connection of the 1082/F to a PCM network requires a straight through twisted pair cable. If you need more assistance with cable selection and preparation, contact Patton Technical Support at (301) 975-1007.

There are no user-serviceable parts in the power supply section of the Model 1082. Fuse replacement should only be performed by qualified service personnel. Contact Patton Electronics Technical support at +1 (301) 975-1007, via our web site at www.patton.com, or by E-mail at support@patton.com, for more information.
Once the Model 1082 is properly configured and installed, it should oper- ate 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 1082, first be sure that you have read “Con- necting Power”...
5.3 TEST MODES The Model 1082 offers two proprietary loopback test modes, plus a built- in V.52 BER test pattern generator, to evaluate the condition of the modems and the communication link. These tests can be activated phys- ically from the front panel, or via the interface. Local Line Loopback (LLB) The Local Line Loopback (LLB) test checks the operation of the local Model 1082, and is performed separately on each unit.
Remote Digital Loopback (RDL) The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 1082s, and the communication link between them. Any characters sent to the remote Model 1082 in this test mode will be returned back to the originating device (see Figure 12). For exam- ple, characters typed on the keyboard of the local terminal will appear on the local terminal screen after having been passed to the remote Model 1082 and looped back.
Using the V.52 (BER) test pattern generator To use the V.52 BER tests in conjunction with the Remote Digital Loop- back tests (or with Local Line Loopback tests), do the following: 1. Locate the 511/511E toggle switch on the front panel of the Model 1082 and set the toggle to the down position.
