Peripheral Cards and Components 4-9 Chapter 4 - Maintenance and Troubleshooting System Functions The following functions are related to system resources and the common equipment boards controlling them. The Master Processor Board provides system central processing, real-time clock, digital (PCM) voice processing and gain control, feature control, customer database, system tone generation, and conference functions. The Modem Unit provides an asynchronous modem for access to the system database and fault reporting features from a remote site. This unit also provides an RS-232 port for local access. The Program Module Unit (PMU) provides the system operating software. Table 4-7: Master Processor Board (MPB) Problem Possible Solutions Complete system failure… †Check AC power source. †Replace the PMU. †Replace the MPB. †Reset the system. SMDR and display phone time-of- day incorrect…Re-program system time and date. Loss of system intercom dial tone and call processing tones… †Reset system. †Replace MPB. Loss of customer database programming…Verify status of initialization switch and database backup battery connection. SMDR RS232C Port inoperative…Check programming. Modem Port (or 2nd RS-232C port) inoperative…Verify Modem Unit, MODU, is installed and programming is correct. Table 4-8: Modem Unit (MODU) Problem Possible Solutions Can not access system database programming remotely…Check Modem programming. Second RS-232C port is inoperative …Check Modem Bypass programming. Table 4-9: Program Module Unit (PMU) Problem Possible Solutions The system is inoperative…Ensure that an operable PMU is installed. The system does not operate without this component.
4-10 Peripheral Cards and Components Chapter 4 - Maintenance and Troubleshooting The Power Supply Unit (PSU) provides direct current power to the system in the form of +30VDC, +5VDC, and -5VDC. LEDs on the PSU in each cabinet show presence of each voltage type. Each PSU provides connections for batteries and charging current for batteries (optional). The Miscellaneous Interface Board (MISB) provides external paging, external contact control, music on hold and background music inputs. The DTRU and DTRU4 provides dual tone multifrequency tones associated with dialing functions. Table 4-10: Power Supply Unit (PSU) Problem Possible Solutions System does not operate (Loss of +5VDC)… †Check LEDs on PSU. †Check power switch. Analog phones and CO Line do not operate (Loss of -5VDC)… †Check LEDs on PSU. †Check power switch. Battery Back-up for system not working…Check to ensure BATT SW is on. Table 4-11: Miscellaneous Interface Board (MISB) Problem Possible Solutions The external paging port does not work… †Check programming. †Check wiring. Some or none of the 4/6 external control contacts do not operate… †Check programming. †Check RAU. Music on hold is not heard…Check music source on MISB and volume control on music source. Background music is not heard… Table 4-12: DTMF Receiver Unit (DTRU/DTRU4) Problem Possible Solutions DTMF Single Line Telephones can not dial out… †If SLT has dial tone, check for installation of DTRU/DTRU4. †If large volume of calls in the system, you may need to add additional DTRUs. DISA calls can’tdialsystem resources after call connection…Check DISA programming. DID lines won’t ring intended station(s)…Check DID programming.
Peripheral Cards and Components 4-11 Chapter 4 - Maintenance and Troubleshooting Miscellaneous Functions The following units are related to other system functions that are external to the KSU. The Ring Generator Unit (RGU) provides ringing voltages for Single Line Telephones. Each Cabinet supporting SLTs must have an RGU installed. The Power Failure Transfer Unit (PFTU) provides automatic cut-over of up to 6 CO lines to up to 6 Single Line Telephones when system power or the central processor fails. Station Card Functions The system can be equipped with various types of station interface cards. The digital key telephone interface board (DTIB) provides the interface for twelve Digital Telephones, DSS/BLF Consoles. Table 4-13: Ring Generator Unit (RGU) Problem Possible Solutions Single Line Telephones do not ring when called on intercom…Check RGU connection. Message Waiting signal to Single Line Telephones with message waiting lamps does not light lamp…Verify correct SLT type programmed (SLT with Msg Lamp in Station ID programming). Table 4-14: Power Failure Transfer Unit (PFTU) Problem Possible Solutions CO lines connected through the PFTU are never available to the system in normal operation… †Make sure the NORMAL/TEST switch on the PFTU is in the Normal position. †Check PFTU programming.

4-16Maintenance Access Chapter 4 - Maintenance and Troubleshooting Event Trace Buffer The Event Trace Buffer is used to store and dump event traces (up to 30) that occur just prior to anXTSSystem soft or hard restart. These can be reviewed by authorized personnel to aid in system troubleshooting. The basic format for each command is shown in the following table: DTMF Receiver Trace The CONFIG utility allows technicians to take specific DTMF receivers in/out of service. This is useful for troubleshooting DTMF receiver problems to isolate a specific DTMF receiver that may be faulty. To view the status of all DTMF receivers in the system: 1. Connect a terminal to I/O Port 1 on the MPB. 2. At theEnter Password>prompt,typeconfig, then press . 3. Then type:dr Table 4-16: Event Trace Buffer Commands Command Function t DisplaysthecurrentstatusoftheEventtracebuffer. t 0 Turns the Trace buffer OFF. t 1 Turns the Trace buffer ON to record events prior to a soft system reset. t 2 Turns the Trace buffer ON to record events prior to a hard system restart. t 3 Turns the Trace buffer ON to record events prior to either a soft reset or a hard system restart. d E Dumps Trace Events stored from last system reset (soft or hard). d b Permits maintenance personnel to determine the busy status of all the busy keysets and CO Lines in the system, including the T1 lines. r SXXX Permits a specific station to be reset. r CXX Permits a specific CO Line to be reset.

Maintenance Access4-17 Chapter 4 - Maintenance and Troubleshooting The display will show the receiver number, cabinet location, card slot location, receiver status, and state of the receiver. To make a receiver unavailable: Type:drXX (XX is the specific receiver number to make unavailable) To make a receiver available: Type:drXX (XX is the specific receiver number to make available) Monitor The Monitor feature provides access to the installed system for diagnostic purposes. These capabilities benefit Service personnel which enables them to support the end user remotely. Different levels of access, via password, allows authorized personnel to trace, monitor and upload critical information directly from theXTSSystem. This provides a more accurate means of acquiring system information that leads to a quick resolution of problems that may occur. This is all done without interfering with ongoing call processing or normal system operation, and in many cases may be performed without a site visit. Port 1 on the MPB and the modem are used for monitor access. The capabilities allowed and reserved for thishigh-level troubleshootingare: Monitor Mode Enable & Disable Event Trace Dump Trace Buffer (up-load) Monitor Password The Monitor password (likeMaintenance), is entered using a six-character alphanumeric string.
