REPARATION

This section provides the requirements for installing the system. The installer should be familiar with this section before installing the system.

ITE

The technician should plan the installation before actual work begins. Advanced planning will minimize time, cost and disruption of the customer’s business activities. Additional benefits include flexibility for changes and expansion, efficient maintenance and increased customer satisfaction.

Precautionary Information

The following warnings shall be observed during installation:

1. Never install telephone wiring during a lightning storm.

2. Never install telephone jack s in wet locat ions unles s the j ack is speci fical ly desi gned for wet locations

3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

4. Use caution when installing or modifying telephone lines.

Site Survey

Inmost cases, a survey of the customer’s premises is needed to develop cost estimates of the installation. Preliminary information is used to determine the placement of the Main Distribution Frame (MDF). A second visit to the site may be necessary to obtain the exact dimensions of the area selected for MDF, cable lengths and possible IDF (intermediate Distribution Frame) locations.

Site Limitations

Installation of a telephone system is seldom a routine procedure. The uniqueness of each customer’s situation requires a tailored approach to each job. In selecting a permanent site for the MDF, the technician may encounter problems such as, but not limited to th e following:

! Limited space is available and must be used regardless of its sui tability. ! The available space may be adequate, but may pose one or more environmental

hazards.

! The proposed location has limitations. Such as insufficient lighting or the lack of a

suitable ground for grounding the KSUs.

Whatever the nature of the adversities encountered, the technician must make the necessary decisions to arrive at the best possible solution for installing the equipment. It is beyond the scope of this document to cover all possible situations, precautions and actions.

Grounding Requirements

The KSU must be properly grounded. This can be achieved by a c orr ectly wi red AC outl et. I f there is any uncertainty, obtain advice from a licensed electrical contractor. Where a ground (other than conduit ground) is used, a grounding terminal is provided on a B614-B13 KSU. (Refer to Figure 2-13:: KSU Grounding, Pg 32.)

Figure 2-13: KSU Grounding

Connecting the B614-B13 KSU

The CPU is the central processing unit (CPU). An 8-bit microprocessor executes the programs stored on the ROM ICs to control the whole system, while transferring data to and from other KTUs.

The KSU consists of a main control section and a Time Division Switch (TDSW) section. It also has an external ringer interface six 4-party conference circuits, two CO/PBX interfaces, six station interfaces and two power failure transfer circuits.

The RAM memory, on the CPU is back up with a non- rechargeable lithium battery whi ch will retain the memory for up to 18 months.

Switch Settings

Before programming System Data, the non-rechargeable lithium battery must be switched on (SW1→HOLD) to allow memory content retention in case of a power failure or brownout. Failure to activate the backup battery circuit may result in System Data being reset to the default values, the status of all stations will reset to the default values and the data programmed on the station may clear if a power failure or brownout occurs. (If programming using a Multiline Terminal, refer to Chapter 2, Programming in this manual for instructions.)

NOTE: Wait at least 30 seconds after turning on system power before changing

memory switch SW1 from CLEAR to HOLD.

When the KSU is removed for long term storage, switch off the lithium battery (SW1→CLEAR). This will prevent the battery from constantly discharging. The battery, when fully charged will retain memory contents for a minimum of three months. (Refer to

Settings, Pg 33

Table 2-1: KSU Switches and Connections, Pg 33

and

Figure 2-14:: KSU Switch

To clear the system memory, use the foll owing procedure.

Telephone Connections

The B614-B13 ETU supports the connection of 6 digital extensions via CN1. Each port requires a single twisted pair cable and the connection is not polarity conscious. (Refer to Figure 2-15:: Telephone Connection, Pg 34)

Figure 2-15: Telephone Connection

Exchange Line connection

The B614-B13 ETU supports the connection of 2 analogue exc hange lines (Cent ral Of fice or PABX) via CN2. This 2-wire connection is not polarity conscious. (Refer to Figure 2-16:: Exchange Line Connection, Pg 34.)

Figure 2-16: Exchange Line Connection

Power Fail Telephone and Fax Connection

The B614-B13 ETU supports the connection of 2 analogue telephones via CN2 for use during period of power failure (i.e. when AC power is lost and the system backup batteries are depleted). Connection of each 2 wire analogue telephone is shown in Figure 2-17:: Power Fail Telephone and Fax Connection, Pg 35. In the event of a power failure the analogue telephones are connected immediately to a CO/PBX line as follows:

FAX/PFT1 ! CO1 (CN2, pins 5-6)

FAX/PFT2 ! CO2 (CN2, pins 7-8)

A detailed explanation of the operation and usage of Power Fail Telephones is given at the end of Section 5.

A6-506000-642-01

If not required as power fail telephone ports, the FAX/PFT ports of CN2 can be used to connect other analogue equipment such as faxes and modems. These devices can make and receive calls as per the normal operation, when the associated trunks are not in used by other users of the system. Note t hat each device is dedicated to a trunk (CO1 or CO2) as indicated above. Any activity by these devices will be shown as a busy trunk status on the handsets of other users on the system.

External Ringer and External Paging Control connection

The B614-B13 ETU supports the connection of an External Ringer, via CN3-RLY, which can be used to activate a locally supplied loud sounding alarm. This alarm can be programmed to sound while an incoming CO/PBX, DID or DIT call is ringing and is ideal for large or noisy areas, or for the hearing impaired. The output of CN3 is a no-voltag e relay contac t opera tion with the following specifications.

Cadence (Cycle): 1 second ON (closed)/2 seconds OFF (open) Maximum Voltage: 24 Vdc Maximum Current: 200 mA

Alternatively, CN3-RLY can be programmed to operate as an External Paging Amplifier Controller. In this mode, the relay of CN3 will close when an external page is initiated and will remain closed until the page is terminat ed. This no-voltage signal can be used to turn on (and off) the locally supplied external paging amplifier. But not that the voltage and current limits shown above will always apply!

Figure 2-18: External Ringer Connection

External Speaker Connection

The B614-B13 ETU provides one pre-amp level output for connection of an External Paging System. This paging system would include as a minimum, a Line Isolation Unit, Audio Amplifier and Speaker. As well as external paging, this speaker may also be sued as alert upon incoming external calls.

the dialling type of the corresponding CO/PBX line (10 pps, 20 pps or DTMF) where it is connected.

General Information

Connection Requirements

The KSU is connected with each of the Multiline Terminals, Single Line telephones, optional equipment and analogue trunks by a separate twisted-pair cable through the MDF. ISDN connection requires two twisted-pair cables. (Refer to Chapter 2 for details.)

Cabling Precautions

When selecting cables and the MDF, future expansion or assignment changes should be given due consideration. Avo id running cables in the following places:

! A place exposed to wind or rain. ! A place near heat radiating equipment or where the quality of PVC covering could be

affected by gases and chemicals.

! An unstable place subject to vibration. ! Close proximity to computers or radio frequency generating equipment.

APR-UA Unit (Analogue Port Ringer)

The Analogue Port adapter with Ringing provides an interface for installing Single Line Telephones, modems, NEC VoicePoint Conferencing unit, and other compatible analogue devices. The APR-UA Unit also generates ringing signals. By providing ring generation, the user can install a personal fax machine or an answering machine for convenience. Two user-adjustable switches are provided on the adapter; one allows for 600<Symbol>W or a complex impedance interface to devices such as a modem or Single Line Telephone, the second switch (SW1) is permanently set to position 2. The APR-UA Unit requires an AC adapter (ACA-UA Unit). If a CTA-UA Unit or the HFU-UA Unit and an APR-UA Unit are both installed, only one AC adapter is required.
