4.9.1 Auto-Negotiation MDR-8000E auto-negotiation is not a stand-alone function, and proper operation and use of all available functions depends on the capabilities of the external customer equipment that is connected to the radio. Just because an autonegotiation function is checked for provisioning does not automatically mean that function is fully operable. The device on the other end of the cable must also have the capability and be provisioned with a matching function. 4.9.1.
4.9.1.4 Input Pause Feature See Figure 4 - 16. Checking the box next to Allow Input Pause makes the auto-negotiation function willing to stop receiving traffic. When the radio input buffers approach overflow, the function sends a pause message to the ink partner that is transmitting data to the radio, telling the device to temporarily stop sending data. The link partner will stop sending data if the device has and is provisioned with the Allow Option Pause function.
4.9.1.5 Allow Output Pause Checking the box next to Allow Output Pause makes the radio auto-negotiation function willing to stop sending traffic. When the input buffers on the link partner approach overflow, the link partner sends a pause message to the radio, telling the radio to temporarily stop sending data. If the Allow Output Pause function is checked, the radio will stop sending out data. 4.10 PROVISION DS1 FACILITY See Figure 4 - 17 to provision the DS1 lines (if equipped).

The Alarm List found under NOC Alarm Troubleshooting on the enclosed CD, identifies every alarm name indicated by the above alarm display equipment, in alphabetic order.
RECOMMENDED PERIODIC CHECKS Perform XMTR local oscillator frequency verification (Para. 5.18) and XMTR output check (Para. 5.19) 1 year after initial setting and at 5-year intervals thereafter to correct possible drift caused by aging. 5.8 RADIO TROUBLESHOOTING The digital radio system is equipped with alarm circuitry and automatic switching (in hotstandby, frequency diversity, and space diversity configurations) to provide protection against loss of traffic.
5.9.3 Troubleshooting Performance Screen Errors Path and intermod problems can occur that cause errors to be indicated on the Performance monitor screens that are not severe enough to generate an alarm on the USI Alarm and Status screen. Errors of this type fall into two categories: burst and dribbling errors. The performance screens can be a useful tool in troubleshooting a radio with and without alarms being indicated on the Status Alarm screen. 5.9.3.
Loss of XMT signal detected at output of PA. If any other alarms are red, go to 1. If not, go to 2. 1. If Off Normal alarm is lit, check 10.5 V switch on power supply is on. If not, remove/replace PA module. 2. Measure RF level at RF MON connector on XMTR module. If level is low, go to 3. If not, go to 4. 3. Measure frequency at XTAL MON connector on XMTR module. If frequency is correct, remove/replace XMTR module. If not, remove/replace XTAL Oscillator Subboard. 4. Remove/replace PA module.
Both RCVRs at the other end have a problem and have switched the XMTRs to try and clear it. If the RCVRs clear within a defined time frame (which we will hereafter call the CLA window) after switching, the CLA appears. if the RCVRs clear by switching or any other way outside of the CLA window, the CLA does not activate, but switching continues. Switching times vary, depending on RSL. If RSL is above alarm threshold, the first XMT switch occurs 5 seconds after the problem at the RCVRs is detected.
TRANSMITTER STATUS A B DS3 I/O INTFC cannot recover framing from incoming DS3 signal or there is no input signal. Is DS3 AIS Detect Alarm on? Yes, troubleshoot upstream radios and external MUX equipment. No, check input signal. If input signal is OK, replace DS3 I/O INTFC. If not, troubleshoot external MUX equipment. DS3 Frame Loss DS3 input to DS3 I/O INTFC has exceeded provisioned BER threshold (high error condition).Troubleshoot external MUX equipment.
Note Always troubleshoot and clear the most severe alarm first. Channel Fail is the most severe, followed by Radio Frame Loss and Eye Closure.
A Channel Fail alarm occurs when RCVR(s) have lost lock and are not locked on the signal from the farend XMTR(s). Loss of signal also means loss of CMD path. The most effective method of troubleshooting this type RECEIVER alarm is to have a technician at both ends of the hop. Farend status viewing and controls must be performed at the farend site.
Note Always troubleshoot and clear the most severe alarm first. Channel Fail is the most severe, followed by Radio Frame Loss and Eye Closure. Loss of radio frame from RCVR in I/O Interface RCVR circuits. Before starting, check USI for receiver Channel Fail alarms and Common Command Path alarm. If there is a Channel Fail alarm, troubleshoot and clear that alarm first. If there is a Command Path alarm, troubleshoot and clear that alarm second. 1. 2. Verify farend radio configuration.
Errors are being received by the RCVR at a rate exceeding the Eye BER threshold error rate provisioned on the radio configuration screen. This alarm could be caused by a faulty XMTR (farend), radio interference on the RF path (RFI), antenna/waveguide problem, or a faulty antenna/waveguide problem, or a faulty RCVR/RCVR local oscillator failure. Troubleshooting is configuration dependent. RECEIVER STATUS A Receiver Fault Receiver On Line Channel Fail Eye Closure 1.
Note Radio Dade is displayed on DS1 USI Status and Alarm screen only. Low RSL on alarmed RCVR. Alarm only functions if AGC switching threshold is provisioned active. 1. Check for path fading. 2. Check upstream XMTR. RECEIVER STATUS A Receiver Fault Receiver On Line High level of distortion in TDE due to excessive multipath activity. Check path for interference.

d Reduce the frequency span on the spectrum analyzer display while keeping the spectrum centered on the spectrum analyzer display. e Continue to reduce the spectrum analyzer span while observing the Res BW field in the bottom left corner of the spectrum analyzer display. f Continue reducing the frequency span until the correct Res BW for measuring carrier for the Radio Capacity/Modulation is displayed. Refer to the following table for the Res BW for measuring carrier required for the radio under test.
CAUTION Possibility of Service Interruption Adjustment of the carrier signal for minimum amplitude is critical. Do not attempt to null the carrier signal until the correct Res BW is reached. Incorrect adjustment can result in loss of traffic due to slow RCVR lock. g Observe the display at the correct Res BW for measuring carrier for a carrier signal rising above the floor of the spectrum. Is a carrier signal rising 3 dB or more above the spectrum visible? No. STOP. This procedure is complete.
a. Center carrier on screen. Note It is extremely important to keep the carrier signal centered in the display so that the carrier will become visible as the span is reduced. b. Reduce Span to 30 mHz. 10 dB above spectrum floor c. Center carrier on screen. d. Reduce Span to 5 mHz. Res BW for measuring carrier Note Res BW automatically decreases as Span decreases.
e. Center carrier on screen. f. Reduce Span to 1 mHz. g. Center carrier on screen. h. Observe Res BW i. Reduce Span to 500 kHz.
Note XMT LVL ADJ PWR MON FREQ CONT XMT PWR ALM You must watch the trace carefully on the spectrum analyzer when adjusting the I and Q carrier controls on the XMTR module. the I and Q carrier controls are interactive and the slightest change on one control causes a change on the other. You must alternate between controls until carrier null is obtained. The direction to turn the controls is not defined.
