CHAPTER 1 INTRODUCTION

1. GENERAL

This manual describes routine system maintenance and fault repair procedures. This chapter explains how to
follow the manual and p rovides precaut ions pertaining t o maintenance jo bs as a whole. Be s ure to read thi s chap­ter thoroughly before starting the req uired maintenance job.

2. HOW TO FOLLOW THE MANUAL

If technicians engage in a fault repair with a sufficient amount of knowledge of the system (system
configurations, controlling systems, functions, etc.), the time spent repairing the system is minimized. This
manual provides explanations about the system, while placing emphasis on system configurations, controlling
systems, and functions. If fau lts of all conceivable cas es are to be assumed for the expl anations, the explanat ions
may lack reality and be more difficult to understand. Therefore, this manual provides the explanations on the
basis of the following points:

(1) It is very important to judge whether the fault has occurred in the system or at any of the peripheral

equipment.

(2) In case the system is faulty, explanations will be given about the actions to be taken until you identify the

faulty circu it card/cards.

(3) Explanations will be omitted pertaining to the following faults:

• Fault of peripheral equipment (MAT, telephone sets, etc.)

• Fault due to an error in office data assignment

• Fault due to an error in ins tall atio n proced ure (an er ror i n circ uit ca rd swit ch s etting, c ross- conn ecti on,
etc.)

(4) How to Read This Manual

• When a fau lt is to be repaired fo r the first time

[ Details on Ether Cable Connections: When using MAT via Ethernet ]

The IPX-U system can use both IOC (PH-IO24) card or each CPR-accommodated LANI (PZ-PC19) card as
an interface for the connection to a MAT. This figure shows an example where a MAT is connected via the
LANI card in PCI slot 01 of each LN/ISW.

Fusion Link

Ether for MAT

This figure is an example where a MAT is connected to LN1 via the 10 BASE-T ca bles
(Ethernet). As seen from this, the MAT, a single terminal connected to the Ether, can control
the whole system status , thus capable of a single-point entry to each LN and ISW.

2.3 Local Partition (LP) Number

The Local Partition (LP) number refers to a logical local processor number, theoretically assigned for each
IMG that consists of four (or less) Port Interface Modules (PIM). Though the local processor does not
actually e xist in any of the IM Gs, ex cept for IMG0, the system can apply the tw o-digit LP number to each
IMG (see Figure 2-17) on i ts data memory program. The LP numbers are used primaril y i n the followi ng
cases:

• Display of system messages

• Assignment of line load control data (ALLC command)

• Backup for Call Forwarding/Speed Calling data (MEM_HDD command), etc.

The Local Partition No. (two digits, even number) is assigned on each IMG.

2.4 Assignment of Network Control Node (NCN)

The IPX-U system can be in service by dialing a T elephone Number assigned for each station at a Network
Control Node (NCN). Because these network-level data (NDM data) can be assigned via the MAT
dedicated to the NCN only, designate any of the following nodes as this network data manager (NCN):

• One of the Local Nodes (LN), excepting for the ISW, within the IPX-U system

• One of the belonging Fusion nodes outsi de the IPX-U system

For more det ails, refer to Figure 2-18.

Note 1:

W ithin the IPX-U sys tem, the NCN can be designat ed only fr om the Loca l Nodes (LN0-LN3). The ISW
cannot be assigned as the NCN.

Note 2:

On a Fusion network, assign only one NCN. Multiple nodes cannot be assigned as the NCN.

Because the Fusion link can be es tablished e ither independe ntly within the syste m (IPX-U) or jo intly with
other outside IPX series, the assignment of NCN can differ, depending on the network configuration.

NDA-24307 CHAPTER 2

SYSTEM MAINTENANCE OUTLINE

Pattern 1 When the system has a Fusion link independently of other systems

If the system has a Fusion li nk only within the system (i.e. no Fusi on link is esta blished with ot her IPX
series), an NCN must be assigned from any of the existing Local Nodes, excepting the ISW. In this
example, LN0 is assigned as the NCN.

The system fin ds a f ault b y its f aul t dete cting c ircui t and th e f aul t detec ting progr am. Once a fa ult occ urs,
the system initiates a remedial action such as system changeover, make-busy setting, or restart processing
by the automatic di agnosis func tion. This ac tion reduces the influe nce of the f ault so t hat system ser vicing
may be minimized. The result of the process ta ken and the fault situat ion are indica ted for equipmen t con­cerned.

Among the faults, those related to speech path (noise , one-way speech, sp eech inability, etc.) are not
detectable. Since t hese f ault r eports a re to be obtaine d from a s tation o r operator, periodic trunk tests mus t
be performed without failure to detect the faults related to speech path.

Figure 2-20 and Figure 2-21 shows an outline of fault detection, and Figure 2-23 shows a block diagram

of fault detect ion.

SYSTEM MAINTENANCE OUTLINE

(a) Main Faults

Faults that may o ccur in the syst em can be general ly categor ized into Processo r System F ault, Speech
Path System Fault, Line/Trunk Fault, etc.

• Proces sor System Fault
The CPU alarm detecting circuit contin uously monitors whether the CPU is working normally. If

a fault is detected, the CPU calls up the diagnostic program, which identifies the cause of the fault
and determines whether the fault is temporary or permanent. When the fault affects system
operations, Active/Standby status of the CPU is changed over (provided that the system has dual
configuration).

• Bus System Fault
The CPU transfers line/trunk card control information to the associated peripheral circuits via IO

Bus. When a parity error is detected in the transfer data or when the required information cannot
be transferred from a circuit card, the CPU identifies the cause of the fault, changes over the CPU
so that system operation is not affected, and executes restart processing.

• Speech Path Fault
The CPU monitors the operating status of the TSW card, the occurrence of errors in writing data

to the switch memory, and the basic clocks s upplied t o the spee ch path. Upon detecti ng a fau lt, the
CPU identifies the cause of the fault, determines whether the fault is temporary or permanent, and
executes required processing such as changeover of the TSW card.

• Others
The alarm detecting circui t on the EMA card con tinuousl y monitors the occ urrence of fa ults in the

PWR supply cards, such as abnormal temperatures within the equipment frame, and lights the
alarm lamp on the TOPU when a fault is detected.

(b) Lamp Indications on the TOPU

When a fault occurs, the corr esponding lamp on the T OPU indicate s the locati on of the f ault. F or the
meaning of each lamp indication, refer to Chapter 6.

CHAPTER 2 NDA-24307

SYSTEM MAINTENANCE OUTLINE

2.7 Range of Faults Specification

(1) Upon receiving a fault report from a station user or an operator, the technician can assume a faulty card

exists if the range to be affected by the fault can be determined. For the de tailed procedure, re fer to

Chapter 5. Use the following actions to check the MDF:

(a) Check the LENS of the reporter (Station or ATTCON/DESKCON).
(b) Check other circuits of the circuit card in which the reporter (station line or ATTCON/DESKCON)

is located.

(c) Check the other groups (ot her ci rcuit car ds mounte d in t he sa me modul e) i n the module i n wh ich th e

reporter is located.

(d) Check lines in each of the other modules on the basis of plural lines.

(2) If the fault cannot be detecte d by the system (a f ault related to the speech path such a s noise during speec h,

one-way speech, speech inability), the range of (a) through (d) (itemized above) should be limited.

(3) When a major faul t is det e cted i n the du al sys te ms , the C PU or TS W sy st em auto m ati c al ly ch ang es over

if the fault ra nge is (c) an d (d). In th is case, the w hole modul e involved is placed into m ake-busy sta tus
even if the fault is partial, and the station lines currently operating normally become faulty status.
Diagnose the fault from the content of the system message displayed and repair the fault as required.

(4) When limiting the range of faults, consider the system circuitry that consists of the control (see Figure 2 -

24 and Figure 2-25, where CPU 0 is active) and speech path systems (see Figure 2-26).

(5) As seen from the block diagrams in Figure 2-24 through Figure 2-27, if a fault occurs within the common

portions to be controlled, all other associated portions are affected by that fault occurrence. If the range
of faults is outside PIM fault, CPU/TSW system changeover is executed (only when the fault is detectable
by the system).

2.8 Explanation of Terms

• C-Level Infinite Lo op
The program repeatedly e xecutes speci fic routines due to a fault of the main memory , data des truction,

etc. The program is not a ble to b e proces se d normall y. This faulty conditi on is re ferr ed to as Program
Infinite Loop. C-Level infinite loop is a state where a clock-level program, which runs under clock
interrupt disable state, is in an infi nite loop status.

• B-Level Infinite Lo op
This is a state where a program infinite loop has occurred during a connection processing and the

connection for the ne xt call is not able to be processed.

• PM (Port Microprocessor)
Each line/trunk card mounted in the PIM is equipped with a processor called Port Microprocessor

(PM), which continuously supervi se s the lines /t runks.

• Ready Error
For acknowledging the connection between the CPU and a circuit card, an interface signal called

Ready Signal is used. When the CPU has accessed a specific circuit card and the normality of the
connection is ac kno wledged, the Ready S ignal is returne d to th e CPU within 6 µs. If t he Ready si gnal
is not returne d to the CPU withi n 6 µs after access, the situation is referred to as Ready Error.

SYSTEM MAINTENANCE OUTLINE

• Parity Error
For confirming the normality of data transfer be twee n the CPU and the circuit card un der the control

of the CPU, parity check is made. When an error is detected in a parity check, it is referred to as Parity
Error. Parity check means to confirm the normality of data by adding an error detecting parity bit to
a set of data to be transferred.

When a set of data is transferred , a parity bit is added to the data so that the data has an even-number
of “1” bits (it is referred to as Even Parity). When there is an odd-number of “1” bits in the received
one set of data, it is detected as an error.

• Monitor Restart
Monitor restart processing suspends current processings in progress without applying any hardware

controlling, allowing the system to restart its operations from the monitor program.
The system abandons only the processings of the calls being handled by the program, and maintains

all the connections that have already been established.

• Circuit Card Front Initializing Restart
The whole system is forcibly initialized. However, the initialization varies with the setting of the

SENSE switch on the DSP of CPU (see Table 2-2).

NDA-24307 CHAPTER 2

Page 39

Issue 1

SYSTEM MAINTENANCE OUTLINE

Table 2-2 Kinds of Circuit Card Front Restart

SENSE (0~F) KIND OF RESTART REMARKS

1 DM Clear Restart
2 DM Load Restart When the system is in operation
5 OAI Memory Clear Restart
C OFF-line Restart

• PM (Line/Trunk Card) Make-Busy Restart
In this processing, the fault y PM (Line/Trunk Card) is isolated from the system and, at the same time,

the calls associated with that faulty PM (Line/Trunk Card) are released. No calls related to the faulty
PM (Line/T runk Card) are processed and t he system normal ly runs without the faulty PM (Line/T runk
Card).

• Data Copy Restart
In a system of dual CPU conf iguration, t he RAM memory (including th e data memory) is copi ed from

the ACT side CPU into the STBY side CPU, and ACT/STBY is changed over and monitor restart is
executed.

In the case of this restart processing, only the ACT side CPU and the STBY side CPU are changed
over without any effect on the current connections. However, no call processings are executed while
the restart processing is in progress (from copying until the end of the changeover).

(3) When a circuit card appears to be faulty, check the following items before replacing it with a spare:

(a) Poor connector contact at the circuit card may be responsible for the fault. Repeat insertion and

extraction of the circuit card a few times. Clean the connector portion, and recheck for proper
operation.

(b) Check the le ad w i re s of vert ic al ly- m oun t ed par ts ( re sis to rs , ca pa ci tor s , e tc .) to ens ure th ey have not

shorted each other or b roken.

(c) Check the back side of the circuit card to see if there is any short-circuited soldered portion, or

modified cross connection wires erroneously left unconnected.

(d) Check the ROMs to ensure proper seating in the IC socket. Figure 2-30 s hows a leg th at is be nt a nd

SYSTEM MAINTENANCE OUTLINE

The following is an example where the fault was recovered after the replacement of circuit cards:

START

Set the 1st circuit card back into its mounting slot

If the fault recurs: Replace the circuit card.

Set the 2nd circuit card back into its mounting slot

If the fault recurs: Replace the circuit card.

Set the 3rd circuit card back into its mounting slot

If the fault recurs: Replace the circuit card.

If a circuit card is found to be faulty, send the faulty circuit card for repair.

The fault may be a temporary one, or due to poor contact of the circuit card. Observe the
situation fo r a while.

END

(8) When a fault recovery is completed, use the RALM/RALMN command to clea r all the alarm indications

and registered system messages. If required, restore temporary cross connections and transient data for
testing to the original ones.

3.2 How to Follow Diagnostic Procedure/Fault Repair Procedure

(a) Diagnostic Work

A fault diagnostic proced ure by system messa ge is expl ained in the “TREE” format o n an individual
system message basis.

• Proceed with judgment as to whether the fault status coincides with the indicated status, following
the sequence beginning from START.

• How to proceed with the diagnosis work is explained in Figure 2-33.

STEP 1 Determine whether the fault coincides with the fault status (1) in Figure 2-33.

STEP 2 If the fault status does coincide, t he fault is indica ted by (2) . Repair the fault by r eferri ng to the

relevant section in Chapter 5. Otherwise, proceed to (3).

STEP 3 Perform the work indicated by (3). The result of the work (3) is broken down as indicated by

(4).

STEP 4 Determine whether the result of work (3) coincides with the status indicated by (5). If so, the

fault(s) is/are indicated either by (6) or by (7). If not, proceed to the next Step.

STEP 5 Perform the work indicated by (8), and if the result of the work is the same as the status

indicated, the fault is indicated by (9). If the fault repair work indicated by (9) affects another
normal line, recheck the work as indicated by (10).

(b) Fault Repair Procedure

A fault repair procedure is explained by means of “TREE” format in Chapter 5. The following
explains how to follow the “TREE” format and proceed with designated work. See Figure 2-34.

• Begin from START and proceed with the necessary repair work following the sequence.

• When a faulty circuit ca rd (or circuit cards) is suspect ed, replace the f aulty circu it card with a spar e
in accorda nc e with the work pr ocedure pertainin g to that specific circuit card.

STEP 1 Replace the circuit card indicated by (A) with a spare and check it. Perform the detailed work

as per (B). If the fault status is beyond repair, proceed to the next step.

STEP 2 If the range of the fault or the system configuration is as indicated by (C), perform a check as

indicated by (D). If the fault status is beyond repair, proceed to the next step.

STEP 3 Replace the circuit card indicated by (E) with a spare and check it. The detailed procedure

indicated by (G) varies with the system configuration indicated by (F).

4. REPORTING FAULT TO NEC

When the cause of a fault is uncertain, make note of the situation involved and report it to NEC. When
forwarding faulty circuit cards to NEC, exercise caution to protect from static electricity.

4.1 Fault Reporting Method

The following three items must be included in the report without fail:

(1) Faulty situation (reports should be similar to “dial tone is not heard only on individual lines,” “incoming

C.O. line calls are not able to be terminated only to a specific ATTCON/DESKCON,” etc. )

• Faulty phenomena
On lifting the handset, d ia l tone is not heard but side tone is heard, etc.

• History of fault
When did the fault occu r? What kind of repair procedur e has been executed? Does the fault still exist

or not exist? etc.

• Range of fault
Range of fault sh ould be report ed: Single li ne?, Specif ic trunk? , Specif ic circuit card?, Speci fic PIM?,

Whole system?, etc.

(2) Circuit Card Version Number, Program Name, and Program Package V ersion Number of the circuit card.

4.2 Forwarding Faulty Circuit Card Method

Send the faulty circuit card to the NEC agent to whom a request is made for a replacement card. Adhere
to the following procedure for sending the faulty circuit card:

(1) Insert connector covers onto the circuit card terminals.

(2) Put the circuit card into a static electricity protective bag.

(3) Pack the circuit card with air cap, etc.

(4) Set the circuit card into the cardboard box for that specific circuit card.

(5) If multiple circuit cards are to be sent, set each circuit card in a separate cardboard box and stuff the box

with shock absorbing material.

Note:

When sending a faulty circuit card, put it in a static guard bag. To prevent damage, NEVER place the
circ uit card in a vin yl bag or ship it without a protective bag .
