Page 11: Section Introduction
This provisioning part of the section describes provisioning options available with the MDR-8000 software application. Provisioning allows for the deﬁnition, editing, and storing of speciﬁc functions. The MDR-8000 provides the ability to provision equipment and facili- ties through a series of Windows™-based screens and messages. The Provisioning menu lists equipment and functions which may be provisioned.
Page 12: Security Management
SECURITY MANAGEMENT Note A password is not required to operate the MDR-8000. The radio is shipped without a password and if a password is desired, it must be entered using the Change Password screen. Once entered initially, the password must be entered each time the user wants to access the provi- sioning screens (level 1 password required) or download software (level 2 password required).

TEST PROCEDURES The radio has been properly aligned and tested at the factory before shipment eliminating the need for testing after initial turn-up. The only time testing and/or adjustment is required is after a maintenance action such as removal and replacement procedure and/or constant alarms requiring corrective maintenance action.

Page 40: Auto-Negotiation
Auto-Negotiation 4.9.1 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 pro- visioning does not automatically mean that function is fully operable.
Page 41 Input Pause Feature 4.9.1.4 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.

Allow Output Pause 4.9.1.5 Checking the box next to Allow Output Pause makes the radio auto-negotiation function willing to stop sending trafﬁc.

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. RADIO TROUBLESHOOTING The digital radio system is equipped with alarm circuitry and automatic switching (in hot- standby, frequency diversity, and space diversity conﬁgurations) to provide protection against loss of trafﬁc.
Page 67: Troubleshooting Performance Screen Errors
Troubleshooting Performance Screen Errors 5.9.3 Path and intermod problems can occur that cause errors to be indicated on the Perfor- mance 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.

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 STATUS viewing and controls must be performed at the farend site.

XMTR REMOVAL AND REPLACEMENT 5.17 Use this procedure to remove and replace the UD-35( ) XMTR and/or Capacity Key and Crystal Oscillator Subboards on the XMTR. Note Spare XMTRs and XMTRs repaired at the factory normally do not con- tain Crystal Oscillator Subboards or Capacity Keys. The user must retain the crystal Oscillator Subboard and the Capacity Key from the module being replaced before sending the module back to the factory for repair.

Transmitter, in service. For out-of-service carrier null procedures, refer to CD. Note Carrier leakage can be nulled in the MDR-8000 using any one of three methods. Method 1 (the preferred method) uses a spectrum analyzer to determine if carrier leakage is present while a modulated signal is being transmitted (in service) and then nulling any carrier present.

Page 109 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. Observe the display at the correct for measuring carrier for a Res BW...
