Page 4: General Information
The Model 1070RC Synchronous Short Range Modem Rack Card operates full duplex, over two unconditioned twisted pair. Supporting data rates to 19.2 Kbps, the Model 1070RC has a maximum range of 10 miles (@ 1200 bps over 19 AWG wire). The Model... - Page 5 The Model 1070RC uses a set of eight DIP switches that allow configuration to a wide range of synchronous applications. These DIP switches are accessible when the card is slid out of the rack chassis.

Page 6: Detailed Switch Settings
Data Rate Switches 1 thru 3 are set in combination to allow the Model 1070RC to be used at data rates from 1200 bps up to 19,200 bps. Switch 1 Switch 2 Note: Switch 4 is not used. - Page 7 RTS/CTS Delay Switches 6 and 7 are used together to specify RTS/CTS delay. After request to send (RTS) is raised by the host terminal, the 1070RC raises CTS after a slight delay in order to give the remote terminal time to receive an incoming signal.

3.3 REAR CARD CONFIGURATION The 1070RC has four interface half-card options: DB-25/RJ-11, DB-25/RJ-45, RJ-45/RJ-11, and dual RJ-45. Each of these options supports one RS-232 connection and one 4-wire connection. Figure 4 (opposite page) illustrates the four different interface options for the... - Page 9 3.3.1 DB-25/RJ-11 & DB-25/RJ-45 STRAP SETTINGS Figure 5 (below) shows strap locations for the Model 1000RCM12511 (DB-25/RJ-11) and the Model 1000RCM12545 (DB- 25/RJ-45) rear cards. These straps determine various grounding characteristics for the RS-232 and twisted pair lines. (peg 1 on left) (peg 1 on top) (peg 1 on left) Figure 5.

Page 17: Operation
Once you have configured each Model 1070RC and connected the cables, you are ready to operate the units. Section 5.0 describes the LED status monitors, the power-up procedure, and the use of the built- in loopback test modes. 5.1 LED STATUS MONITORS The Model 1070RC features ten front panel status LEDs that indicate the condition of the modem and communication link. - Page 18 1070RC when its card-edge connector makes contact with the chassis' mid-plane socket, or when the chassis' power supply is turned on. Note: The 1070RC is a "hot swappable" card--it will not be damaged by plugging it in or removing it while the rack is powered up.

Local Analog Loop The Local Analog Loop test mode causes any data sent to the local 1070RC by the local RS-232 device to be echoed back to that RS- 232 device. For example, characters typed on the keyboard of a terminal will appear on the terminal screen. - Page 20 APPENDIX A. MODEL 1070RC SPECIFICATIONS Transmission Format: Synchronous External Interface: RS-232C/CCITT V.24 connection via DB-25 Female; EIA/TIA-561 connection via RJ-45 (10 wire); twisted pair connection via RJ-11 or RJ-45 (8 wire). Internal Interface: Connection to Model 1000R16 rack chassis via 50 pin male card edge.
