Installation Requirements
Site Planning
Select a KSU location that has enough space for easy installation, is well ventilated and has adequate lighting. Select a KSU location to minimise station cable lengths. Maximum cable length is 400 metres using AWG 24 cable for telephones. Equipment should not be exposed to direct sunlight, corrosive fumes, dust, constant vibration or strong magnetic fields such as motors, copying machines, etc. A direct commercial AC power outlet is required. Do not use an extension cord. Ensure that all wires and cables going to and coming from the KSU are properly routed. Do not cross fluorescent lights or run parallel with AC wires. The equipment must be located within a temperature range of 0o - 45oC and a humidity range of 10% - 90% (without condensation). Do not install equipment within a 2-mile radius of a broadcasting antenna.

Installation Procedure
Mounting the KSU
Select a wall that is strong enough to support the weight of the KSU (maximum 4.5 kg). Select hardware that will support the system when it is mounted. It is recommended that the KSU be mounted on a plywood backboard no less than 1.5 mm thick. Secure the KSU with screws using mounting holes in flanges on right and left sides (Figure 2). Do not over-tighten the screws or the slots on lefthand side of KSU could be squeezed closed. Plug in the KSU.

Grounding the KSU
NX - 308 system requires a solid earth ground to the KSU frame (maximum 50 ohms). Failure to provide an adequate ground may cause confusing trouble symptoms or even circuit board failure. In most cases, the third wire ground at the AC power outlet will be satisfactory. If you are not sure of a good, solid ground on third prong of outlet, connect the grounding lug on KSU to a ground rod or metal cold water pipe using 10 AWG solid copper wire. NB: Do not use both methods of grounding. Use only one path to ground. The third wire of the electrical cord may be disconnected from the power supply board then taped and stored, if you connect ground through the other path.

WARNING Hazardous voltages may cause death or injury. Observe extreme caution when working with AC power line voltage.

Internal Music Source
NX-308 system is equipped with a melody chip containing six melodies which run continuously: "La Reine Deo Saba" "For Elise" "Santa Lucia" "Maiden Pray" "Music Box Dancer" "Moonlight on the Colorado" The system has two music sources which may be selected by the related shunt pin, J37, on the base board (Figure 4). Near shunt pin J37 are two identifying marks INT and EXT: INT position EXT position Selection for Internal Music Source Selection for External Music Source

Volume levels are adjusted by the variable resistor, RV1, near the shunt pin. Note: When the customer does not want internal or external music provided, disconnect the external music source and select external music by moving the shunt pin.

External Music Source Connections

NX - 308 system is equipped with an internal melody chip to provide music on hold and background music through the keysets. However, an external music source such as a radio or recorder can be connected to the system.

The system has two music sources which may be selected by the related shunt pin, J37, on the base board (Figure 4). Near shunt pin J37 are two identifying marks INT and EXT: INT position EXT position Selection for Internal Music Source Selection for External Music Source.

Volume levels are adjusted by the variable resistor, RV1, near the shunt pin. Use one-pair twisted cable, 24 AWG. The external music source can be connected through MDF. IMPORTANT When Music On Hold is used it may be necessary for a Performing Rights License to be held. Consult your supplier.

External System Paging Connections
Use one-pair twisted cable, 24 AWG. The external amplifier is connected through the MDF. Refer to the Amphenol connection table in Figure 3. Ring and Tip terminal for external system paging has no polarity. The output impedance is 600 ohms. If the amplifier input impedance is less than 600 ohms, the output level is reduced. The output level of the external page circuit is fixed. Volume adjustments must be made at the customer's amplifier. This external speaker and amplifier may be installed at the system for use by all users. External individual paging is different from this speaker; external individual paging is set up on a keyset basis and can be installed at each keyset.

Connecting Door Phone and Lock Control
NX - 308 system users can communicate with an optional door phone when it is installed. Prepare a three-pair twisted cable for the door phone and lock release. Connect the voice pair and power pair to the door phone unit. Take care when connecting the power pair because of its polarity. Connect the third pair to the customer-provided electronic door lock unit for control of the door lock release mechanism. Refer to the Amphenol connection table in Figure 3. Note: Door lock release control is to be used for low-voltage relay control only. Do not connect to commercial AC power. Relay maximum rating : 1 AMP, 24 VDC When the door phone is required by the user, you should install the unit provided by Securicor Telecoms. Any other unit will not work with the system.

20

The lock release mechanism controls door opening only and does not lock the door. The maximum rating of the control signal connected to the system should be less than the specifications described above.

Connecting PSTN Lines
NX 308 system operates with loop start C.O. lines which have no polarity. Three loop start C.O. or PBX lines can be connected to the system.

Telephone company lines should be terminated on an LJU located near the KSU. Connect PSTN lines to CO1, CO2, and CO3 by connecting the modular plug supplied to the system PSTN modular jack. The other end of the cable should be connected to the LJU. Cabling PSTN line cord RJ11 Connector Pin 1 Pin 2 Pin 3 Pin 4 Yellow Green Red Black TIP BT Connector Pin 2 Pin 3 Pin 4 Pin 5

RING

Note that the cable for trunk lines (C.O. or PBX lines) should be isolated from the cables for the stations, preventing signal interference and surge inducement.

Power Failure Transfer
NX-308 system transfers two C.O. lines to the related single line telephones automatically during AC power failure. The first trunk line and the second trunk line are transferred to the 7th station and 8th station respectively only when the stations are assigned to single line telephones. Trunk 1 to Station 7 Trunk 2 to Station 8 For power failure transfer, you should assign DIP switch S7 on the base board correctly. The DIP switch includes four levers and each telephone line requires two lever adjustments. Set to the ON position to enable this feature (Figure 4). If a facsimile station is installed at the system, assigning the FAX station to one of these ports is useful because you can receive fax messages regardless of power failure.

AC Power Connection

21

The system operates with 220 VAC and is equipped with two fuses: AC Fuse Battery Fuse 1 AMP, 250 VAC. slow acting 3 AMP, 250 VAC, slow acting

If failure occurs, replace only with same type and rating of fuse.

Connecting System Back-up Battery
NX - 308 system will continue full operation during AC power failure (or "brown-outs") when a 24V battery supply is connected. To supply 24 volts, use two 12V batteries or four 6V batteries connected in series. Any battery used must have a rating of not more than 40 AH and not less than 6 AH. The required connector with red and black leads is supplied with the KSU: Red lead Black lead = = Plus (+) Minus (-)

Power supply circuitry will monitor and recharge batteries as required. A 10 AH battery will keep the KSU and six keysets fully operational for approximately six hours. WARNING Take extreme caution when connecting live batteries to avoid personal injury or damage to the system.

Memory Protection
NX - 308 system is equipped with a memory back-up battery that prevents loss of the customer database, stored in RAM, during a power failure. The 3.6 V DC Ni-Cd battery is connected through switch J38 in the top righthand corner of the base board (Figure 4). This memory back-up is turned off at the factory before shipping to preserve battery life. Immediately after installation of the KSU, switch J38 to ON. Allow 48 hours of continuous operation to fully charge Ni-Cd battery.

Installing Surge Protection Equipment
The system is equipped with adequate surge protection circuitry at telephone line interfaces and power supply input interfaces. However, for additional surge protection it is recommended that surge protection equipment is installed.

Before Power On

22

Before switching the power on, ensure that: The KSU is reassembled correctly. All cables are correctly connected and that twisted pair cables are used. The system is grounded adequately. AC power is settled in a valid range. AC power selection switch is correctly set according to the installation site or AC outlet. All selection switches are correctly set; in particular, memory back-up switch J38 is set to ON. AC power switch is OFF. Plug the power cord into the AC power outlet and switch the system AC power switch to ON. Ensure that the system works correctly. Otherwise, contact your installer.

SYSTEM PROGRAMMING

Levels of Programming

25

This section provides system programming instructions. Programming can be done at any electronic station port equipped with a display keyset. There are three levels of programming: Technician, User (Customer) and Station. All system programming can be accessed by entering a technician's password at any display station. (Only an authorised person can program the features which apply to all stations in the system.) User programming is intended for customer's use and allows limited access to system programmes via a user-level password. The attendant keyset will use this level of access to enable specific features. Station programming can be done at any station without a password because these features apply to that station only. This section describes technician- and user-level programming. Station programming is described in the NX-308 Keyset User Guide. Features operate when the system is turned on because they are factory programmed with default data. You may use the features as factory programmed (default) or change them. Programming should be done using the following procedures while on-hook. 1. The system must first be set into `program enable' mode: Enter: 20 Password 0/1 (where 0 = Programmable Disable 1 = Programmable Enable)

2. To program each feature: Enter Program Number Enter Data Reminder: Set J38 (top righthand corner of base board in Figure 4) to ON before entering customer data. Failure to do so will result in loss of data during a loss of power to the system.

Toll Restriction Examples
NX-308 programming provides for all eight stations to be assigned an individual class of dialling. There are five classes (see program # 30). Because class A has no restrictions and class E cannot make outside calls, these require no additional programming. However, classes B, C and D must be assigned, in other programs, the digits they are allowed or restricted from dialling.

Classes B and C have a deny list assigned to each. Class D is intended for stations with limited outside calling requirements and which therefore can only dial what is in their allow list. Each of these allow or deny lists has 10 entries (0 - 9) with a maximum of 12 digits in each entry. Toll restriction is configured as follows: CLASS B DENY LIST Prog # 33 0 - 9 Example 1 : ALLOW LIST Prog # 34 0 - 9 CLASS C DENY LIST Prog # 35 0 - 9 ALLOW LIST Prog # 36 0 - 9 CLASS D ALLOW LIST Prog # 37 0 - 9

Class of service B phones need to dial 1-800 numbers, 1 plus 7 digits and local calls. They are to be restricted (denied) 0 + calls, 976, and 1 + any area code + 7 digits.

You would program this as follows: # 33 Deny Class B Entry 0=0 Entry 1=1*0 Entry 2=1*1 # 34 Allow Class B Entry 0=1800

34

Entry 3=976 Example 2 : Class of service C phones need to dial 1 + A/C + 7 digits, 1-800, and local calls. They are to be denied 1-900, 976, 1-A/C-976, 0 + calls, and 411 calls.

You would program this as follows: # 35 Deny Class C Entry 0=0 Entry 1=1900 Entry 2=976 Entry 3=1***976 Entry 4-411 Example 3 : Notes: 1. 2. 3. # 36 Allow Class C

(No Entries Required)

Class of service D phones need to dial 911 for emergencies only. Program # 37, Entry 0 = 911.

`*' indicates any digit dialled. Exceptions to a deny entry are listed in the allow table. Pressing the HOLD button will enter the letter "E". This means end of dialling - no more digits are allowed.

# 39

LCR Programming (Technician) Forced LCR
If LCR is enabled on any line and the user presses the line key rather than dialling `9', the system still forces the user to use LCR.

MMC900

LCR Enable

Used to enable LCR. When LCR is enabled, a valid trunk group access code (9 or 80) must be entered in MMC47 and 40. The NX-308's LCR system provides a means to automatically route calls over specific trunk groups according to the digits dialled. The method of programming makes no assumptions about office codes, area codes or number of digits dialled. It is therefore suitable for any country in the world with any numbering plan.

44

When enabled, LCR is invoked by dialling an access code; this code is usually 9. LCR is enabled in this MMC on a trunk by trunk base. NX-308 provides a "fake" dial tone to the station user as a signal to begin dialling. The digits are dialled but are not immediately sent to the C.O.; they are stored in a buffer for analysis by LCR Digit Table. System toll restriction checks each digit as it is dialled to determine if the call is allowed for the dialling station. Action 1. 2. 3. 4.

MMC902 LCR Route Table
LCR Route Table is responsible for selecting a specific trunk group in the completion of an outward bound call. This table works in conjunction with LCR Digit Table and LCR Modify Digit Table. After the user dials a valid digit string, the system uses LCR Route Table to select a specific predetermined trunk group. A maximum of 16 routes are available, beginning with the Route Number. If more than one group is available for call completion, the system will use the first designated trunk group and then start to use succeeding trunk groups. If all trunk groups are busy in a selected route, call queue will become active and allocate trunks as they become available. Action 1. 2.
