Acknowledge command and the link is established Data originates at the local DTE and is looped at the Remote PROCESSOR back to the Local DTE Note that the data is also passed through to the Remote DTE and is not squelched When a Remote unit enters RDL it changes its Restart timeout to one minute the reason will be explain in the RDL with 511 511E section If the line is discon nected the local unit will Restart NS led activat ed after 4 6 seconds but the Remote unit will wait for one minute before it Restarts Note that the transmit data at the Remote DTE is ignored When the switch is thrown or the DTE removes the RDL request the local unit will transmit an RDL_OFF Request to the Remote unit The local unit will keep its TM led active until this request has been completely sent out If the switch is thrown again before the completion of the termination phase the switch will be ignored until it is placed back into the normal position Figure 12 Block Diagram Remote Loop 28 Remote Digital Loop with 511 511E The Remote Digital Loop with 511 511E is shown above After RDL is established the Remote units Restart Timer is set to one minute This has been done because when the 511 511E generator is started on the local unit the Remote framer begins seeing unframed packets The Remote unit can not distinguish the 511 511E pattern from the line being dis connected so the Restart Timer has been lengthened to allow the
6. TERFACE The Model 1095 supports communication between two DTE devices at distances to 5 miles 8 km over 24 AWG 5mm twisted pair wire There are two essential requirements for installing the Model 1095 1 These units work in pairs Both units at the end of the twisted pair must have the same 2 Wire connection and DTE rate 2 To function properly the Model 1095 needs one twisted pair of metallic wire This twisted pair must be unconditioned dry metallic wire between 19 9mm and 26 AWG 4mm the higher number gauges will limit distance Standard dial up telephone circuits or leased circuits that run through signal equalization equipment or standard flat modu lar telephone type cable are not acceptable The RJ 45 connector on the Model 1095 s twisted pair interface is polarity insensitive and is wired for a two wire interface The signal pin relationships are shown in Figure 4 below 4 2 CONNECTING THE SERIAL PORT The serial port interface on the Model 1095 uses interchangeable QuikConnect Modules Each QuikConnect Module has a 50 pin card edge connector on one side and a serial port interface on the other Figure 4 below shows how a QuikConnect Module plugs into the back of the Model 1095 Figure 5 Installation of Model 1095 Plug in Serial Interface Module 4 2 1 Changing QuikConnect Modules When you purchase a particular version of the Model 1095 it should be shipped to you with the appropria
