1.1 RADIO AND TV INTERFERENCE  
The Model 2073RC generates and uses radio frequency energy, and if  
not installed and used properly-that is, in strict accordance with the man-  
ufacturer’s instructions-may cause interference to radio and television  
reception.The Model 2073RC has been tested and found to comply with  
the limits for a Class A computing device in accordance with specifica-  
tions in Subpart B of Part 15 of FCC rules, which are designed to provide  
reasonable protection from such interference in a commercial installa-  
tion. However, there is no guarantee that interference will not occur in a  
particular installation. If the Model 2073RC does cause interference to  
radio or television reception, which can be determined by disconnecting  
the unit, the user is encouraged to try to correct the interference by one  
or more of the following measures: moving the computing equipment  
away from the receiver, re-orienting the receiving antenna and/or plug-  
ging the receiving equipment into a different AC outlet (such that the  
computing equipment and receiver are on different branches).

Status. Blinks yellow from one to eleven times to indicate system status.  
Each pulse pattern is separated by a 2 second “off” period. Greater  
pulse patterns have higher priority (buffer saturation has greater priority  
than an empty MAC table). Valid system statuses are:  
• 1 pulse = system status ok  
• 2 pulses = No MAC entries in the MAC address table  
• 3 pulses = Clear to send (CTS) or Carrier Detect (DCD) from base unit  
are not asserted  
15  
 
       
• 4 pulses = IMRC2/IAbuffer is saturated  
• 5 pulses = WAN receive frame(s) too large  
• 6 pulses = WAN receive frame(s) not Octet aligned  
• 7 pulses = WAN receive frame(s) aborted  
• 8 pulses = Detected WAN receive frame(s) with bad CRC  
• 9 pulses = Detected LAN receive frame(s) too large  
• 10 pulses = Detected LAN receive frame(s) not Octet aligned  
• 11 pulses = Detected LAN receive frame(s) with bad CRC  
After a status code is displayed eight times and the associated condition  
is removed, the status code will no longer appear.

4.0 INSTALLATION  
This section describes the functions of the Model 1001R14 rack chassis,  
tells how to install front and rear Model 2073RC Series cards into the  
chassis, and how to connect to the twisted pair interface and the serial  
interface.  
4.1 THE MODEL 1001R14 RACK CHASSIS  
The Model 1001R14 Rack Chassis (see Figure 10) has 14 or 16 device  
card slots, plus a single power supply or dual redundant power supplies.  
Measuring only 3.5” high, the Model 1001R14 is designed to occupy only  
2U in a 19” rack. Sturdy front handles allow the Model 1001R14 to be  
extracted and transported conveniently.  
Figure 10. Model 1001R14 Rack Chassis with power supply  
The Rack Power Supply  
The power supply included in the Model 1001R14 rack uses the same  
mid-plane architecture as the modem cards. The front card of the power  
supply slides in from the front, and the rear card slides in from the rear.  
They plug into one another in the middle of the rack. The front card is  
then secured by thumb screws and the rear card by conventional metal  
screws.  
There are no user-serviceable parts in the power  
supply section of the Model 1001R14 rack. Volt-  
age setting changes and 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  
WARNING  
[email protected], for more information.  
18  
 
     
Powering up your 1001R14 rack  
The power supplies that come with your 1001R14 rack system are  
equipped with a power entry connector on the rear power supply card.  
The power supplies are hot-swappable, so you are not required to  
remove the cards from the rack while applying power to the system.  
Note Please refer to the Model 1001R14 Series User Manual AC and  
DC Rack Mount Power Supplies for fuse and power card  
replacement information.  
4.2 INSTALLING THE MODEL 2073RC INTO THE CHASSIS  
The Model 2073RC is comprised of a front card and a rear card.The two  
cards meet inside the rack chassis and plug into each other by way of  
mating 50 pin card edge connectors. Use the following steps as a guide-  
line for installing each Model 2073RC into the rack chassis:  
1. Slide the rear card into the back of the chassis along the metal rails  
provided.  
2. Secure the rear card using the metal screws provided.  
3. Slide the card into the front of the chassis. It should meet the rear  
card when it’s almost all the way into the chassis.  
4. Push the front card gently into the card-edge receptacle of the rear  
card. It should “click” into place.  
5. Secure the front card using the thumb screws.  
Note Since the Model 1001R14 chassis allows “hot swapping” of  
cards, it is not necessary to power down the rack when you  
install or remove a Model 2073RC.  
4.3 CONNECTING TO A DTE DEVICE  
The serial port on most rear interface cards are hard-wired as “DCE”  
(Data Communications Equipment). The interfaces are designed to plug  
into a DTE such as a terminal, PC or host computer. When making the  
connection to your DTE device, use a “straight through” cable. When pur-  
chasing or constructing an interface cable, refer to the pin diagrams in  
Appendix B on page 25 as guides.  
4.4 CONNECTING TO A DCE DEVICE  
The rear interface cards on most interface modules are hard wired as  
“DCE”.Therefore, you must use a tail circuit cable when connecting to a  
modem or other DCE device. When purchasing or constructing a tail circuit  
interface cable, use the pin diagrams in Appendix B on page 25 as a guide.  
19  
 
       
Note Pin-out requirements for tail circuit applications vary between  
equipment manufacturers. If you have any questions about a  
specific installation, please contact Patton Electronics Technical  
Support.  
4.5 CONNECTING TO A G.703/64 KBPS NETWORK  
The Network Line Interface is an 8-position keyed modular jack config-  
ured as an RJ-48C (see Figure 11).

5.0 OPERATION  
Once the 2073RC is installed and configured properly it is ready to place  
into operation.This section describes the function of the LED indicators,  
and the use of the loopback and pattern test modes.  
5.1 LED DESCRIPTIONS  
The 2073RC is equipped with 12 LED indicators that monitor the status  
of communication.  
TD  
RD  
When the unit sends a one, the TXD LED is green.When it  
sends a zero, the TXD LED is yellow.  
When the unit receives a one, the RXD LED is green.When it  
receives a zero, the RXD LED is yellow.  
CTS  
CD  
Glows green to indicate that the clear-to-send signal from the  
2073RC is active.Yellow indicates inactive CTS.  
Glows green to indicate that the a carrier from the remote  
modem is being received.  
DTR  
Link  
TM  
Glows green to indicate that the DTE attached to the 2073RC  
is active.  
The Link LED lights when the unit is synchronized with the  
incoming 64k/G.703 network signal.  
The Test Mode indicator will turn on when the unit enters local  
or remote loopbacks. It will also turn on when test patterns 511  
or 511ER are activated.  
ERR  
The error LED indicates various error conditions, when send-  
ing a test pattern, the LED will remain lit if the unit does not  
receive the identical pattern. When it receives the correct pat-  
tern, the LED will turn off.If error insertion is on, the LED will  
blink once a second if everything is operating properly.  
21  
 
   
Loop (V.54 & Telco) Diagnostics  
The 2073RC offers two loop diagnostics for diagnosing the 2073RC and  
any communication links.These tests can be activated via signals on the  
serial port interface or the front panel switch.  
Operating Local Loopback (LLB)  
The Local Loopback (LLB) test checks the operation of the local 2073RC  
and is performed separately on each unit. Any data sent to the local  
2073RC in this test mode will be echoed (returned) back to the user  
device (i.e.,characters typed on the keyboard of a terminal will appear on  
the terminal screen).  
Figure 12. Local loopback  
To perform a LL test, follow these steps:  
1. The Local Loop can be initiated from the 2073RC unit either by acti-  
vating the LL signal on the DTE (if you are not sure which lead is the  
RDL signal, please refer to the Appendix,) or by toggling the top  
front panel switch towards the label “LLB”. The Yellow TM (Test  
mode) LED will turn on to indicate a successful Local loop condition.  
2. Verify that the data terminal equipment is operating properly and  
can be used for a test.  
3. Perform a V.52 BER (bit error rate) test bit error rate (V.52) diagnos-  
tics.If the BER test equipment indicates no faults, but the data termi-  
nal indicates a fault, follow the manufacturer’s checkout procedures  
for the data terminal. Also, check the interface cable between the  
terminal and the 2073RC.  
22  
 
   
Operating Remote Digital Loopback (RDL)  
The Remote Digital Loopback (RDL) test checks the performance of both  
the local and remote 2073RC as well as a point-to-pointcommunication  
link between them. Any characters sent to the remote 2073RC in this test  
mode will be returned back to the originating device (i.e,characters typed  
on the keyboard of the local terminal will appear on the local terminal  
screen after having been passed to the remote 2073RC and looped back).  
Figure 13. Remote loopback  
either by activating the RDL signal on the DTE (if you are not sure  
which lead is the RDL signal, refer to Appendix B “Interface Pin  
Assignment” on page 25) or by toggling the top front panel switch  
towards the label “RDL.The Yellow TM (Test mode) LED will turn on  
to indicate a successful RDL.  
2. Perform a bit error rate test (BERT) using the internal V.52 generator  
(as described in section “Bit Error Rate (V.52) Diagnostics”, turn the  
Bit error rate (V.52) diagnostics on or using a separate BER Tester.If  
the BER test indicates a fault, and the Remote Line Loopback test  
was successful for both 2073RC you may have a problem with the  
twisted pair line connection.  
Bit Error Rate (V.52) Diagnostics  
The 2073RC offers V.52 Bit Error Rate (BER) test patterns that can be  
invoked along with the LLB and RDL tests to evaluate the unit(s) and the  
communication links. When a 511 test is invoked, the 2073RC generates  
a pseudo-random bit pattern of 511 bits, using a mathematical polyno-  
mial.The receiving 2073RC then decodes the received bits using the  
same polynomial.If the received bits match the agreed upon pseudo-ran-  
dom pattern, the 2073RC and the communications link are functioning  
properly. 511 or 511/E is initiated by setting the bottom front panel switch  
towards the label ‘511’ or 511E” respectively. The Yellow TM (Test mode)  
LED will turn on to indicate activation of the 511 or 511E test modes.
