INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE SPECIFICATIONS Issue 2, May 1990 indicate that the buffer on the attached device is full, the KCB will not send data. 5.7 The APM 52 port will send a logic true ( > + 5V) on pin 6 (Clear to Send) while it is ready to receive data. If the buffer on the APM becomes full, a logic false (< -5V) will be sent. In addition, the APM will monitor pin 1 (Request to Send). The APM will only send data if it receives a logic true ( > + 5V) over pin 1. If the APM receives a logic false (< -5V) to indi- cate that the buffer on the attached device is full, the APM will not send data. 5.8 TheAPMJlportwillsendalogictrue(> +5V) on pin 1 (Clear to Send) while it is ready to receive data. If the buffer on the APM becomes full, a logic false (< -5V) will be sent. In addition, the APM will monitor pin 6 (Request to Send). The APM will only send data if it receives a logic true ( > + 5V) over pin 6. If the APM receives a logic false (< -5V) to indi- cate that the buffer on the attached device is full, the APM will not send data. 5.9 If using the port on the KCB, the programming terminal and output device must communicate at 300, 1200,2400, or 4800 baud. Baud rates are set by placing the DIP switches on the KCB in the desired position. (Ihe location of the switches is shown in Figure 3-16 on page 3-31.) 5.10 If using the 52 (to DTE) or Jl (to DCE) port on the APM, the programming terminal and output de- vice must communicate at 1200 baud. 5.11 Other programming terminal and output de- vice specifications include: l The data format must be 8 bit standard ASCII. l Parity is off (ignored). l Communication is full duplex. l There is one start bit and one stop bit. 5.12 For remote programming, the system requires an external, auto-answer modem that is capable of ASCII asynchronous serial data communication. The customer-provided modem is connected directly to an RS-232-C port (either the KCB or an APM) and to an available APM circuit or an available C.O. line (re- fer to INSTALLATION, page 3-48, for details). The programming device must also be equipped with a modem. 5.13 The SMDRSAR output device(s) must be able to print reports with a width of either 60 or 80 characters. Also, the cable(s) between the device(s) and the KSU must not be longer than 50 feet (15 me- ters). 5.14 For save/restore operation, the storage device (e.g., a personal computer) must be capable of storing a minimum of 1OOK bytes of text. All other character- istics are the same as described for the programming terminal. B. SYSTEM BATTERY BACK-UP 5.15 To provide back-up power in the event of an AC power failure or brownout condition, the GMX-48 System power supplies can have optional battery back-up using the unit designed for the system or using a customer-provided uninterruptable power supply (UPS) unit or standby power supply (SPS) unit. 5.16 If installing the battery back-up unit (part no. 662.0110) designed specifically for use with the GMX-48 System, complete informationdand installa- tion instructions are included with the unit. 5.17 If installing a UPS or SPS unit, it is recom- mended that it have the following characteristics: Sine wave output Transfer time of less than 20 milliseconds Output rating of 365 Watts (minimum) for the 662.0100 power supply, 175 Watts (minimum) for the 662.0200 power supply, and 100 Watts (mini- mum) for the 662.0600 power supply Batteries can be external or internal Low voltage cutoff circuit of 105VAC (minimum) NOTE: Even if the power supply unit has the specifi- cations listed above, it cannot be guaranteed that it will work properly with the GMX-48 System. Contact Inter-Tel Customer Support for a listing of approved units. 5.18 Batteries connected in series form a “string.” The voltage of the string is equal to the sum of the in- dividual battery voltages. For example, five 6V batter- ies connected in series form a 30V battery pack. If desired, connect two strings in parallel to double the amp/hour rating, which results in longer discharge rates; the voltage level remains the same as a single string. Page 2-17
SPECIFICATIONS Issue 2, May 1990 ‘.. INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE 5.19 Batteries must be fully charged when installed. Charge each individually using a constant-voltage, current-limited charger with less than three percent ripple. The charge voltage per cell must be set accord- ing to the manufacturer’s specifications. Be careful not to damage the batteries by overcharging them. For example, new Globe brand batteries require 25 days of float voltage or 25-30 discharge cycles to at- tain full capacity. Initial capacity might only be 80 per- cent of rated capacity. 5.20 All batteries should be of the same age and am- pere-hour (AH) rating. Some manufacturers date batteries by stamping them with a date code. For ex- ample, Globe stamps their batteries with a code such as 410-B, where 4 = the last digit of year, 10 = the month, and B = the type of electrolyte. If a battery in a string needs to be replaced, the age of the string will determine if a fresh battery can be added. If the string is two to three years old, adding a fresh battery will reduce the life of the entire string. This is because a fresh battery will be overcharged, while the older bat- teries are undercharged. 5.21 Batteries may give off explosive and/or corro- sive gases. To reduce the effects of this gas, place the batteries (or battery compartment) in a room with good ventilation and coat the terminals with an anti- corrosive agent. Avoid storing batteries; they will self- discharge and their capacity decreases with age. If you must store batteries, recharge them every six months. Recharge time may vary depending on the charger’s current limit and the battery’s state of charge. C. DOORBOX 5.22 For a doorbox application, Inter-Tel recom- mends the Valcom V-2901 Universal Door Answer- ing Unit. This unit, along with the Valcom V-1070A Door Plate SpeakeF, is hooked up to a C.O. circuit on the GMX-48 System. When a person presses a button on the door plate speaker, the unit generates ringing on the C.O. line. By answering the ringing line, a sys- tem user can talk with the person at the door. If the door is equipped with an electric strike plate, the sys- tem user may allow access by dialing a code or press- ing an external button. To call the Valcom doorbox, the system user goes off hook and presses the line key assigned to the unit (or dials the appropriate C.O. line access code). 5.23 In database programming, the C.O. circuit as- signed to the Valcom unit should be programmed as “not subject to toll restrict.” It should alsobe assigned a C.O. line identification name, such as: DOOR 1. 5.24 The Valcom door answering unit and talkback speaker can be ordered from a local supply house. In- stallation and operation instructions are included with the unit. D. VOICE MAIL NOTE: Available only in the Intermediate and Ad- vanced software packages. 5.25 If desired, an optional single- or multi-port voice mail system can be connected to an APM on the GMX-48 System. Depending on the specific capabili- ties of the voice mail system used, calls can easily be placed, transferred, or forwarded to the voice mail unit. After a message is recorded, a message waiting indication is left at the appropriate station location, and the message can easily be retrieved by the user. 5.26 For additional information and for specific voice mail unit recommendations, contact Customer support. E. FAX MACHINE NOTE: Available only in the Intermediate and Ad- vanced software packages. 5.27 A facsimile (FAX) machine allows the trans- mission of a picture, drawing, or document over a standard phone line to be reproduced by another ma- chine at the receiving end. This can be an efficient, cost-effective communication tool. 5.28 Standard installation procedures for FAX ma- chines involve connecting the machine to a dedicated line for sending and receiving documents. With a GMX-48 System, the FAX facilities are integrated with the telephone system and make use of many of the GMX-48 call processing and money saving fea- tures. Some of the special capabilities that a GMX-48 System can add to a FAX installation include the fol- lowing: l Outgoing FAX calls can be placed using automatic route selection (ARS) to make the best use of long .-. distance lines and reduce costs. _:’ Page 2-18
INTER-TEL PRACTICES GMX-48 INSTALLATION 8z MAINTENANCE SPECIFICATIONS Issue 2, May 1990 e l Incoming FAX calls can ring in directly to a FAX machine or a group of machines, and/or they can be answered by an attendant (human or auto- mated) and transferred to the FAX machine. This allows FAX calls to come in on any line; there is no need for a dedicated line. Multiple FAX machines can be placed in a hunt group or in a “call forward no-answer” chain. In- coming FAX calls can then be sent to a single in- tercom number where they can be processed even if one machine is busy or out of service. When FAX documents are received, a designated operator (keyset station) is notified immediately by a flashing MSG key and a display. Each FAX machine can have a different designated operator. Assigning forced account codes to the FAX sta- tions can prevent unauthorized use of the ma- chines or their telephones. The SMDR and SAR features can help track out- going FAX calls for billing purposes. The GMX-48 System is compatible with standard FAX machines; there are no special require- ments. 5.29 A FAX machine can be installed on any unused APM circuit. The circuit is identified as a FAX port and assigned a FAX message center in station pro- gramming. The station can also be placed in a hunt group, assigned incoming and outgoing lines, as- signed a forced account code, assigned a user name, etc. 5.30 An example of a FAX installation that uses the automated attendant, hunt group, and message cen- ter features is shown below. In this example: Incoming calls‘are answered by an automated at- tendant. Three FAX machines are connected to APM cir- cuits. The FAX machines are in a hunt group. A 24-line display keyset station is the designated FAX message center for the FAX machines. 0) (2) (3) (4) (5) (6) (7) (8) 5.31 A call rings in and is answered by the auto- mated attendant. The caller hears a message such as, “Thank you for calling. Dial 1 for Sales, 2 for Service, or 3 to send a FAX.” The caller dials 3. FAX #1 is busy (being used to send or receive a document) so the call goes to the next machine in the hunt group. FAX #2 is out of service and does not answer so the call goes to the third machine in the hunt group. FAX #3 answers the call and receives the FAX transmission. The MSG key at the FAX message center lights and the display shows “MESSAGE RE- CEIVED FROM FAX #3”. The keyset user clears the message by pressing the asterisk (*) key and goes to pick up the transmitted document from the FAX machine. The following example shows the use of ARS, forced account codes, and SMDRISAR records. The FAX circuit has been programmed with ARS-only and a forced account code. (1) (2) (3) (4) (5) Using the FAX machine telephone, the user dials the ARS feature code (default is 80) and the assigned forced account code. The system checks the account code. If it is not valid, the user hears reorder tones. If the code is valid, the user can dial the telephone num- ber of the receiving FAX machine. The system checks ARS and places the call on the selected line. The receiving FAX machine answers and the user transmits the document. The system logs the call and its account code in the SMDR and SAR records. Page 2-19
