2. NOTICE WHEN USED

2.1 Consideration of PBX, Power-related Equipment and Peripheral Equipment

This item describes the consideration before using PBX, the power-related equipment, and the peripheral equip-

ment (such as console, MDF, DAU, telephone, PC, printer, etc).

Preserve the following:

DANGER

When the system gives off smoke or burning smell, it might cause a fire, an electric

shock, or a failure if the system keeps operating. Turn off the power and confirm the

smoke disappears, and then contact supplier.

If equipment (such as PBX, Main Power, cabinet, and peripheral equipment) fall down

and be broken, turn off the power, and then contact the supplier.

If the inside of PBX or Main Power is wet by liquid such as water, turn off the power.

It might cause a fire, an electric shock, or a failure if the system keeps operating.

Do not touch the internal parts of Main Power for the purpose of disassembly and re-

modeling. It might cause a fire, an electric shock, or a failure.

(NEC does not take any responsibilities if the system or the equipment is disassembled

or remodeled.)

Do not put any container (such as vase, cup, and cosmetics) on Main Power and periph-

eral equipment. It might cause a fire, an electric shock, or a failure.

DANGER

Do not damage, remake, forcefully bend, forcefully extract, nor forcefully twist an elec-

tric code and a wiring to/from PBX, Main Power and peripheral equipment. It might

cause a fire, an electric shock, or a failure. If the wiring is damaged, ask the supplier to

fix it.

Insert the electric plug into the outlet properly. Confirm no dust is on the blade of plug;

it might cause a fire.

Do not use other than the power designated when installed.

Do not try to fix or move Main Power by yourselves without the supplier or service tech-

nician’s help. Please ask them when the repair or the movement is necessary.

Do not put any metal or combustible object into a vent of PBX, Main Power, and the

peripheral equipment. If the object is in those equipment, turn off the power and ask the

supplier. It might cause a fire, an electric shock, or a failure if the system keeps operat-

ing.

Be careful of using the display part which the peripheral equipment has. In the case of

liquid crystal, the liquid is leaked and causes harm to human body and systems.

Before connecting customer-provided equipment (such as the other company products)

with NEC products such as PBX and peripheral equipment, ask the supplier and make

sure your equipment is compatible with NEC product. If it is not confirmed, do not con-

nect them. It might cause a fire or an electric shock.

WARNING

Fix the equipment. Do not put any object on PBX and Main Power; it might be danger-

ous if the object should fall down.

When plugging off a plug, be sure to grip the plug and extract it. If you grip the code

and extract it, it might cause a fire and an electric shock.

If a fault is considered as the lightening cause, ask the supplier.

Other than fulfilling the appropriate humidity and temperature, it is necessary to consid-

er the maintenance operation and the all-time ventilation in non-loading operation dur-

ing day-off and night. For example, when the height above floor is 1 m (3.281 feet), the

temperature should be from 20 to 25 °C (68 to 77 °F ) and the humidity should be more

or less 50 %.

WARNING

Be careful of using a battery as following:

Rechargeable lead battery is used as the emergency battery of PBX. Check the back-

up for an electricity failure.

Battery electrolyte is harmful to human body. If the battery electrolyte is put on the

cloth, clean it using enough amount of water.

Do not cause the battery short intentionally. Do not put it near fire or put it into fire.

Do not damage it, such as disassembly, falling, and impact.

The battery life varies depending on the surroundings. The battery life is approxi-

mately three years. If the battery is used outside with high temperature, the battery

life is shortened to approximately one year.

If not replacing terminal or dead battery, the PBX system will not work in case such as

power failure. Besides it might cause smoking or fire due to leaking battery electrolyte.

Perform the periodic diagnosis surely. Note that the battery is one of periodic replace-

ment parts whose cost are charged to the customer. We recommend you to make a con-

tract with supplier or service technician about the routine maintenance.

Do not touch the peripheral equipment by wet hand. Do not wet the peripheral equip-

ment.

Do not touch the ink head and the internal of the printer. When replacing the ink ribbon

or the paper, make sure it is cool enough.

Do not drop nor impact the peripheral equipment. It might cause a failure.

2.2 Notice Regarding Lightenning Strikes

ATTENTION

Do not use benzine, thinner, and alcohol for cleaning. When it is difficult to clean dust

and dirt, put weaken neutral detergent onto a cloth, and give the cloth a wiring. Clean

dust and dirt with the cloth, and rub them with a dry cloth.

Do not place equipment in the following:

Locations which receive direct sunlight

Locations where the moisture exceeds the allowed level

Locations which might be wet with water, oil, and chemicals

Locations which is particularly low in temperature (such as an ice compartment)

Locations which receive the electric wave or the magnetism from TV and (two-way)

radio

Locations which receive the illegal electric wave

Note that the life of PBX and Main Power is shorten if placed in the location affected

by much of hydrogen sulfide or salt, such as seaside area.

WARNING It is necessary to take proper procedures to avoid damage to the PBX caused by local lightening strikes

and other electrical surges.

As for grounding conductors, there needs to be two-type grounding conductors; one is below 10 Ω

(Type 1) and the other is below 100 Ω (Type 2). In particular, the Type 1 is used for the electronics

circuit installment, therefore, it must be used as isolated system to keep from electricity difference

caused by lightening strikes.

The Type 1 is used when connecting the FE of PBX, the PE of Main Power, MDF, etc.

Extract the ground terminal (grounding electrode of three terminals) from the earth board same with

that of the main equipment. The ground terminal attached with AC100V plug outlet is used for MAT,

printer, MODEM, and measurement machine for maintenance.

CHAPTER 2 GENERAL INFORMATION FOR CCIS

1. GENERAL

This chapter describes the functional outline of CCIS, hardware required for CCIS, and service features which can

be provided by CCIS.

2. DESCRIPTION OF CCIS

The modular architecture and wide range of voice and data features available with the digital PBX’s have been de-

veloped with emphasis on continued enhancement within a single PBX. In order to meet the growing demand for

further enhancement on a network level, NEC developed a networking system employing Common Channel Inter-

office Signaling (CCIS). The CCIS system links together individual PBX systems (nodes) to form a transparent

voice and data network which acts as a single large PBX, even though terminals within the network are, in fact, con-

nected to different PBX’s. Common Channel Interoffice Signaling (CCIS) derives its name from the fact that a sig-

naling channel (link), separate from voice and data channels, is provided between nodes for the sole purpose of

signal exchange. This signaling link is used in common by all voice and data links for exchange of information re-

lating to addressing (e.g. dialed digits, calling/called number); supervisory functions (e.g. call setup and termina-

tion); and network accounting and management (e.g. centralized billing and fault reporting.) This is unlike

conventional tie line networks which exchange signaling information over the same links as are for voice transmis-

sion (Associated Channel Interoffice Signaling.)

The block diagrams in Figure 2-1 and 2-2 illustrate the difference between Common Channel Interoffice Signalling

(CCIS) and Associated Channel (In-band) Interoffice Signaling (ACIS).

Some advantages of the separate signaling link provided by CCIS are:

(a) Network Transparency

Because CCIS allows data relating to service features and station/trunk status to be exchanged between nodes

at a high rate of speed (64 Kbps), service is provided to all users as though the CCIS network was a single PBX.

(b) Centralized Facilities

Centralized Management: Fault messages from all nodes can be directed to one centralized (management)

node.

Centralized Billing: Billing information for all nodes in the network can be processed at one central

location.

Centralized Attendant Service: It is not necessary in a CCIS network to have an Attendant Console at each

node in the network. Attendant services can be provided to multiple nodes from

one or more central location(s).

Because network signaling is carried over separate signaling links, more efficient use can be made for network

trunks (reduced call holding time, reduced connection time, etc.). In another word, the number of trunk cir-

cuits, which required to provide a specified traffic capacity, can be reduced.

GENERAL INFORMATION FOR CCIS

(d) Network Reliability

Alternate Routing provides the CCIS network with maximum reliability. If the signaling link between two

nodes should fail, signaling is sent over an alternate route, via another node, without loss of service. Directly-

connected redundant links can also be provided to assure the reliability of the network.

(e) Reduction in Personnel

Because management, cost accounting, and services, such as Attendant operation, can be centralized, the num-

ber of people necessary to administer the network can be reduced.

(f) Reduced Hardware

Signaling over a common channel; better utilization of trunking facilities; and centralized management and

services all result in a vast reduction in hardware when a CCIS network, rather than a conventional Tie line

network, is used.

3. SYSTEM CONFIGURATION

3.1 Outline

This Section describes the hardware configuration and its specification, the names of interface equipment and other

related subjects. Figure 2-3 shows No. 7 hardware configuration, respectively. The control signal circuit used for

CCIS is classified into the digital circuit and analog circuit. The CCH card can be used for both digital and analog

control signal circuit and the CCT card is used for digital one. CCH sends control signals to and receives from the

distant office. Also, for network synchronization, PLO/OSC or TSW (Phase Lock Oscillator/Oscillator or Time Di-

vision Switch) are used.

For the analog control signal circuit, CCH circuit card is used with MODEM.

4. NETWORK CONFIGURATION

With application of No. 7 CCIS added to the PBX, a network of multiple functions as if it were a single PBX.

Since calls can be freely transferred between one PBX and another, most of the existing station services can be ap-

plied to inter-PBX call connections.

Further, using the CENTRALIZED BILLING-CCIS service and the CENTRALIZED SYSTEM MANAGEMENT

REPORT-CCIS service, billing information and fault information can be processed at one center point instead of

processing at each PBX concerned.

of network configuration for CCIS Analog Line.

GENERAL INFORMATION FOR CCIS

4.1 Types of Network

CCIS networks can be divided into the following types, depending upon the numbering plan used:

Main-Satellite Networks

Main-Remote/Campus Networks

Both networks provide uniformity of services throughout the CCIS network, and, because of numbering plan flex-

ibility, station users are not conscious of the distance between nodes.

Main/Satellite Network:

In this type of network, offices are connected by means of a numbering plan consisting of a three-digit office code,

which denotes the location, and four-digit station numbers. An example of a Main/Satellite Network is shown in

Figure 2-6.

Main-Remote/Campus Network:

In these types of networks, offices are connected by means of a numbering plan consisting of four or five digit station

numbers. The first one or two digit(s) of these station numbers are used to denote the location. An example of a

Main-Campus Network is shown in Figure 2-7. Figure 2-8 shows an example of a Main-Remote Network. In this

network, a part of the Main Office is installed as a Remote Office at a nearby site, either within or outside the pre-

mises of the Main Office. An advantage of this network is that it requires far less cabling than would be necessary

if stations were connected to a single PBX. Network numbering specifications are summarized in Table 2-2.

4.3 CCIS Network Modes

The signaling channels of a CCIS network can be connected in one of two ways: Associated Mode or Quasi-Asso-

ciated Mode.

4.3.1 Associated Mode

An Associated Mode network is configured with a signaling channel (data link) between all nodes in the network.

Signaling functions for all inter-node calls are carried over these dedicated signaling channels. In an Associated

Mode Network, if one of the signaling links should fail, signaling can easily be rerouted via another node. An ex-

ample of an Associated Mode network is shown in Figure 2-9 below.

Common Signaling Channel

ND-71762 (E) CHAPTER 2

Page 13

Issue 2

GENERAL INFORMATION FOR CCIS

4.3.2 Quasi-Associated Mode

In Figure 2-10 below, nodes A and B, and A and C are connected in the Associated Mode. Nodes B and C are con-

nected in the Quasi-Associated Mode.

In this configuration, signaling data between nodes B and C is routed via node A, while the communication channels

are established directly between nodes B and C. This type of network reduces the hardware necessary to establish

the signaling links.

Figure 2-10 Quasi-Associated Mode Network

4.4 CCIS Network Redundancy

To provide maximum network reliability, two levels of redundancy are provided for the signaling links.

(1) Signaling Channel Redundancy

Redundancy of the inter-node signaling links is provided directly between the nodes by adding one more link

than is necessary for the signaling traffic. This is the N+1 method. If one link fails, signaling is automatically

routed via an alternate link.

(2) Alternate Signaling Path Redundancy

An alternate method of providing network signaling redundancy is to configure the network so that an alternate

path is provided between the nodes.

In the network shown in Figure 2-9, if the signaling link(s) directly connecting nodes B and C should fail, the

signaling would automatically be reconnected via node A without loss of service. (Node A would be designated

as the Signaling Transfer Point [STP]).

5. DIGITAL NETWORK AND NETWORK SYNCHRONIZATION

5.1 Outline

To set up a digital network, it is necessary to establish clock level synchronization among the offices composing the

network.

Among various kinds of synchronizing methods, the PBX is using Receiver synchronization as the standard method.

As for the office ranks, there are the following four kinds:

• Source Office

• Sub-Source Office

• Receiver Office

• Local Receiver Office

Refer to Table 2-3 for synchronization method at network-level.

For types of PBX applicable for each office hierarchy, refer to Table 2-4.

×: Applicable —: Not Applicable

The clock precision is as follows.

M-OSC EXT. OSC High precision - PLO/OSC Subordinate - PLO/TSW

Note 1: M-OSC (Master Oscillator) and EXT. OSC (External Oscillator <for back up>) is not to be furnished by

NEC.

Note 2: High Precision Oscillator - PLO (PH-CK17) / OSC (PA-CK14)

Subordinate Oscillator - PLO (PH-CK16) / TSW (PH-SW10)

For the 1-IMG system, the OSC/TSW card is used in place of PLO.

5.2.3 Receiver Office and Local Receiver Office

For connecting the DTI (Digital Trunk Interface) of the user office to the DTI of a higher-ranking office, the user

office must establish clock synchronization with the higher-ranking office concerned.

A Receiver Office or a Local Receiver Office extracts carrier clocks (24DTI: 1.544 MHz/30DTI: 2.048 MHz) from

the DTI opposing to the higher-ranking office and establishes clock synchronization with the higher-ranking office

by supplying the extracted carrier clocks to the PLO/TSW (Subordinate oscillator) in the user office.

GENERAL INFORMATION FOR CCIS

Table 2-5 shows the algorithm for changeover of input clocks from the DTI. The Table shows how the PLO selects

a specific route for input clocks according to the input clock status of four routes, thus establishing clock synchro-

nization. For example, in a case where Route 1, which has been selected due to a fault occurrence to clock input

Route 0, has also become faulty, Table 2-5 should be looked up as follows:

STEP 1: Look at Route 1 block under “Selected Route Before changeover” (the current input clock route) column.

STEP 2: Under “Each Route Input Clock Status” column, look for the block which shows that only Routes 0 and

1 are faulty.

STEP 3: Under “Route To Be Selected After Changeover” column located at the right extremity of the Table,

Route 2 is indicated in the block corresponding to the block found in Step 2.

If a route of which priority order is higher than the current route has been restored to normal, the route is changed

over to that specific route.

6. NETWORK THROUGH FCCS GROUPS AND NEAX2000 IPS Internet Protocol Server

6.1 Network Configuration

The network through multiple FCCS Networks (FCCS Groups) and NEAX2000 IPS Internet Protocol Server system

can be realized to manage the telephone number data in those systems altogether and to centralize functions in the

network.

* FCCS Group: network where multiple NEAX2400 IPXs are connected via FCCS link.

* In this section, NEAX 2400 IPX system is described as IPX and NEAX2000 IPS Internet Protocol Server system

is described as IPS.

GENERAL INFORMATION FOR CCIS

1. The following table shows the network type classification.

IPX: NEAX 2400 IPX IPS: NEAX 2000 IPS Internet Protocol Server

For these network types, the following services are realized or enhanced.

Number Portability - CCIS [N-46]

Centralized Maintenance - CCIS [C-167]

Centralized Billing - CCIS [C-55]

Centralized System Management Report - CCIS [C-57]

Message Center Interface - CCIS [C-67]

For availability of the other services in this network, see “Feature and Specifications Manual”.

2. There are two connection types for the network.

a.) IPS - IPX connection

b.) IPX - IPX connection

6.2 Conditions for Network Establishment

•IPS - IPX

1. Additional IPS cannot be connected to IPS that has already been connected with IPX. (Only one SPAN is

allowed for IPX-IPS connection.)

2. A maximum number of routes and that of nodes for the IPS system are given by subtracting the number of

routes (LGRT) used for the IPX system from 899 (maximum number of routes in an FCCS group).

Note: This condition is applied to the IPX side. The IPS system may accommodate up to 255 nodes (including IPX)

because the maximum number of Point Codes (PCs) assigned at IPS system is 255.

3. When a signal route is deleted, another signal route can be shared with multiple routes (the voice route is

required per route). However, when the network is established using EVENT BASED-CCIS (For details,

ISDN System Data Design Manual), the signal route is required per route.

•IPX - IPX

1. The maximum number of nodes per FCCS group is 253.

2. The maximum number of routes assigned in each FCCS group is 899.

3. An individual NCN and NDM exist in each FCCS group.

GENERAL INFORMATION FOR CCIS

6.3 FCCS Group (FUG)

1. Since multiple FCCS networks are connected in the network, FCCS network group number is required to

distinguish each FCCS network from others. An FCCS network group is called FCCS group (FUG), and a

maximum of 4 FUGs can be connected in the network.

2. A center FUG should be specified from among multiple FUGs in the network. It is the sole node allowed

assigning and deleting telephone numbers within the self FUG and the others.

3. The network consists of FUGs and NEAX2000IPS systems within the range of 2 SPANs from the center

FUG and within the range of 4 SPANs from end to end.

2.1.5 PAD Setting

When setting up a No.7 CCIS Network, PAD setting differs from that in the case of analog network.

(a) For an outgoing call to/incoming call from a Tie Line:

• Via “ARTD” command (CDN=30) or by switch setting on the circuit card (DTI/CCT).

(b) For a tandem Tie Line connection:

• Via “APAD” command or switch setting on the circuit card

At both the originating and terminating offices, 0 dB is set to the outgoing side and 8 dB is set to the terminating of

the DTI/CCT route via “ARTD” command or switch settings.

At the tandem office, 0 dB is set for both the terminating and originating sides of each DTI/CCT route via “APAD”

command.

This arrangement is shown in Figure 5-4.

BASIC DATA ASSIGNMENT

Since Point Code is used to identify each office in a CCIS network, any identical PCs are not allowed in the

same network. The following three kinds of point codes may be programmed in the system. The first PC, Orig-

inating Point Code (OPC), is mandatory. The remaining two Point Codes can be assigned as required.

• Originating Point Code (OPC): assigned by Indexes 180 and 181.

• Centralized Billing Point Code (DPC 0): assigned by Indexes 182 and 183.

• Centralized Management Point Code (DPC 1): assigned by Indexes 184 and 185.

1) Originating Point Code (OPC):

The OPC is a self-office code, which should be assigned without exception. 14 bits can be used for specifying

OPC. Note that available PC ranges from 1 to 16367 (PCs16368~16383 are used for Loop Back Test). Node

A whose OPC is 10, for example, should be assigned as follows.

2) Centralized Billing Point Code (DPC 0): Note 1

The DPC 0 is used when billing information of the PBX (Node A) should be sent to the Centralized Billing

Office. When DPC 0 is assigned as “20”, for example, billing information of Node A can be obtained at Node

B whose PC is 20. When this Centralized Billing feature is not necessary, skip these Indexes.

Note 1: Assign DPC 0 = 00 Hex to Centralized Billing Office.

3) Centralized Management Point Code (DPC 1): Note 2

The DPC 1 is used when system messages of the PBX (Node A) should be transmitted to the Centralized Man-

agement Center, from which all PBXs in the network can be managed. When DPC 1 is assigned as “30”, for

example, system messages can be automatically sent to Node C whose PC is 30 in this case.

Note 2: Assign DPC 1 = 00 Hex to Centralized Management Office.

BASIC DATA ASSIGNMENT

2.3 FCCS Data Assignment Procedure

This section explains the basic data assignment to be required when CCIS services are activated in an FCCS Net-

work. Feature and Specifications Manual shows the CCIS services allowed in an FCCS Network. See “FCCS Net-

work System Manual” and “Office Data Specification Manual” for details.

Note: This data setting is necessary for the following services since they may be provided to FCCS system.

•CENTRALIZED MAINTENANCE-CCIS [C-167]

•NUMBER PORTABILITY-CCIS [N-46]

For details of this feature, see “Feature Programming Manual”.

When the above features are used, there are conditions of FCCS data assignment as described below.

1. When connecting the stand-alone PBX, non-FCCS system, with another FCCS Group (FUG) or

NEAX2000IPS,

(a) The system must be the NCN.

(b) The system is programmed as the FCCS Network configured by one NCN only.

2. When connecting the NEAX2400IPX system and the NEAX2000IPS system, CIC (Circuit Identification

Code) =1 should always be assigned using ACIC2 command.

3. Common Channel Handler (CCH) location of the Common Channel Signaling Controller Group (CSCG) data

(CCH location per CSCG) must be programmed against each PC of the connected IPX or IPS system using

ACSCL command.

4. PCs (Point Codes) in the network through FUGs and IPS are programmed as unique (All PCs used in the net-

work are different).

For the system to be connected with the next system via CCIS link or the large sized network, this assignment

is basically recommended.

5. The CCH to be used is selected as follows.

when the call is processed using the speech line (Bch), the outgoing/incoming route (Logical Route: LRT)

decides CCH.

LRT → PC → CSCG → CCH

when the call is processed without speech line (Bch) - inter-office service such as CALL BACK, MES-

SAGE WAITING service, MCI, etc., the called party’s number or PC of the destination decides CCH.

(a) the called party’s number → LRT → PC → CSCG → CCH

(b) PC → CSCG → CCH

when logging into IPS or IPX in the remote FUG from the Centralized-MAT, PC of the node to be logged

in decides CCH.

(a) IPS

PC → CSCG → CCH

(b) IPX in Remote FUG

FUG + FPC → PC → CSCG → CCH

*FUG and FPC to be designated for logged-in node are converted automatically within the system.

2.2 Technical Terms for Explaining Message Detail Data

Some technical terms are used to explain the detail data in each system message and circuit card information. Some

technical terms and the circuit card mounting information, which are used in common to explain the various system

message, are shown below.

Phase 1 Restart Processing Execution

All the processing being executed is suspended, and the system operations are allowed to restart from the monitor

program without any hardware controlling involved. More specifically, the processing on calls being handled by the

programs are abandoned, and all the connections already established are maintained.

Phase 3 Restart Processing Execution

By initializing each PM (Line/Trunk circuit card), the following processes are executed:

• Forcibly releasing the calls connected with the initialized Lines/Trunks.

• Releasing the related links.

Data for Analysis by NEC Engineers

These message detail data are used by NEC engineers when analyzing faults, and thus they are not used in ordinary

fault repair works.

When a fault is complicated one, the data are used when reporting the fault to NEC or when NEC engineers inquire

about the fault.

MAINTENANCE PROCEDURE

2.3 How to Proceed with Diagnostic Work from System Message

The diagnostic procedure after seeing a system message is illustrated in Figure 8-2. Judge whether the fault status

coincides with the indicated status, following the sequence beginning with START.

STEP 1: Judge whether the fault coincides with the fault status (1).

STEP 2: If the fault status does coincide, the fault is indicated by (2). Repair the fault according to paragraph ×.

×. × as shown by (3). Otherwise, proceed to (4).

STEP 3: Perform the work indicated by (4).

The result of the work (4) is broken down as indicated by (5).

STEP 4: Make a judgment as to whether the result of work (4) coincides with the status indicated by (6).

If so, the fault is indicated either by (7) or by (2’). If not, proceed to the next step.

STEP 5: Perform the work indicated by (4’), and if the result of the work is the same as the status indicated, the

fault is indicated by (2’’).

If the fault repair work indicated by (2’’) affects another normal line, recheck the work as indicated by

(8).

(5): Branching as the result of the operation (4)

(6): Judgment of the status as the result of the operation

(7): If, as a result of a fault diagnosis, the faulty condition cannot be reproduced and is judged to be

temporary, this information is displayed.

In this case, clear the indicated alarm and the system message using the RALM command and

place the system under supervision to see if the same fault recurs.

(8): While a fault repair is in progress, perform various operations such as system changeover, ini-

tialization, etc. When such operations are performed, they affect the normally operating station

lines, attendant consoles, trunks, etc. in the form of momentary disconnection, speech interrup-

tion, forced release of calls in progress, etc.

By comparing the urgency of the required fault repair with the above-mentioned effects on the

lines, trunks, etc., determine the proper timing for performing the necessary recovery work.

“13-B”: CCH C-Level Infinite Loop Failure. (Permanent)

(1) Meaning

The system message “13-B” indicates that C-level infinite loop (Note) of the PM (Port Microprocessor) within

the CCH/CCT circuit card has occurred more than 15 times within an hour. When this fault has occurred, the

specific PM is placed into make-busy state and restarted. (The fault counter is “0” at the beginning of every

one hour.)

Note: This is a state in which the C-Level Monitor Program (the program which detects off-hook/on-hook related

to lines/trunks) repeats a specific routine. The number of times to be repeated is counted by the error-

counter corresponding to the CPU.

(2) Related System Message

When the C-level infinite loop failure occurs less than 16 times, the Phase 1 restart or Phase 3 restart is exe-

cuted at the specific PM of CCH/CCT card and the system message “13-C” is output.

MAINTENANCE PROCEDURE

3. CCIS (Common Channel Interoffice Signaling) Line Fault

This paragraph explains the fault repair procedure when any of the faults shown in Table 8-1 occur to a specific

CCIS line.

3.1 Check Point

When repairing a CCIS Line fault, consider the following:

(1) Check alarm lamps on the CCH or CCT circuit card

(2) By referring to Figure 8-5, check the cable connection.

3.2 CCIS Line Control

The CCH within the CCH/CCT circuit card controls the signal link of the interoffice common channel signaling sys-

tem and transmits/receives call processing information.

The signal link controls to send/receive the call processing information.

The call processing information is converted into No. 7 signal format for channel 1 (any channel) of the DTI before

being transmitted to a distant office.
