2.10 Using The External Paging Interface The system provides a special transformer-isolated paging port that you can use to couple the system to a customer-supplied external paging amplifier. This external paging port does not provide a talk-back path nor will it recognize DTMF dial tones. You can use the relay closure dry-contact points that the system makes available at the ringing port terminal for controlling the external paging amplifier during a paging operation. These contacts close and stay closed during the time that a paging operation is active to provide a constant enable signal path for the paging amplifier. NOTE: This paging enable constant closure function overrides the ring pattern closure provided when ringing is sent to the paging port. ·Connect the audio input of a customer-supplied external paging amplifier to the paging port. ·If the paging amplifier requires an enable signal, connect the enable leads to the station 17 audible terminals.

2.11 Using A Line Port As An External Paging Interface You can use class of service programming to program a line port to be an AUXILIARY port. As an AUXILIARY port, a user can use it to couple a telephone to an external paging device that you have wired to the line port. He or she does this from any station with that line presence by pressing the proper line button to select the AUXILIARY port. The user can dial DTMF tones or dial pulses through the AUXILIARY port as needed. The paging enable relay closure feature discussed previously is not available for use with this installation. ·Connect the audio input of a customer-supplied external paging amplifier to the tip and ring leads of the AUXILIARY port. ·You can install a DTMF tone select, zone-paging amplifier if you wish. If you do install this type of amplifier, the user must dial the zone-select code after he or she presses the AUXILIARY port line select button.

2.12 Connecting Data Devices To The System The DSU II includes serial data ports for use. The common equipment cabinet provides these ports as standard modular jacks labeled COM 1 and COM 2 This section contains information on two stages of wiring these connections for data devices. Section 2.12.1 explains connections from stations to modular jacks. Section 2.12.2 details wiring from the modular jack to the DSU. 2.12.1 Making Modular Jack Data Connections Modular jack connections are wiring connections from a station to a modular (wall) jack. The system provides two serial data ports on the J0408 and four serial data ports on the J0816 and J1632 for use. ·When you use a personal computer (PC) to perform class of service programming or to load system software into the system, connect it to COM 1. ·When you use a serial data printer for SMDR, SMDA, COS printout, or Caller ID, connect it to the COM 2. NOTE: The distance between a data device and the common equipment can be up to 500 feet in a quiet electrical environment. Some sites may require shielded cable for long runs. For longer distances, you must install limited distance modems to relay the data communications between the common equipment and a data device. When preparing a cable for connection to a data device, refer to the manufacturer’s manual for the equipment being interfaced and make the following wiring connections: ·Wire the common equipment RD (data from device to common equipment) connection to the device TD (transmit data) connection. ·Wire the common equipment TD (data to device from common equipment) connection to the device RD (receive data) connection. ·Wire the common equipment SG (signal ground) connection to the device SG (signal ground) connection. ·If required for proper operation, wire the common equipment CTS (clear-to-send status from device to common equipment) connection to the device RTS (request-to-send) connection. NOTE: The common equipment requires a positive voltage, with respect to signal ground, in order to send data.

2.12.2 Making The Common Equipment Data Connections You must make wiring connections from the modular jack (wall jack) to the common equipment cabinet modular jack for the data connection. The default data communications format is as follows: ·8-bit data with 1 stop bit and no parity ·Baud rate of 9600 baud. Configure a data device to match this format for initial operation or reprogram the system’s data format to match those of a data device. The tables below list the system’s data ports. NOTE: The distance between a data device and the common equipment can be up to 500 feet in a quiet electrical environment. Some sites may require shielded cable for long runs. For longer distances, you must install limited distance modems to relay the data communications between the common equipment and a data device.

2.12.3 Connecting A Personal Computer For Remote Programming You can connect a personal computer (PC) to the DSU II digital telephone system remotely through modems as described below. (For information on direct connection, refer to Section 2.12.1. ) You will need the following customer-supplied equipment: ·PC and appropriate software program, ·Pair of data modems. The data modems must be: “Hayes-compatible,” capable of 300-, 1200-, 2400-, or 9600-baud data speeds, and have auto-answer capability. Be sure to verify the auto-answer capability before purchasing the units. You are assured of best results if you employ modems of the same make and model at both the installation site and the remote programming site. Make the equipment connections per the following procedure: 1. Determine the signal needs of the modem from the user’s manual for it. (The digital telephone system only requires TD, RD, and SG but the modems may require more signals. Check with the modem manufacturer for special requirements). 2. Wire the proper connector (to match the data jack) on one end of a length of multiline cable. 3. Punch down the appropriate leads on the connector block. 4. Connect the network jack of the data modem to an outside telephone line. (If a line is not reserved for remote programming, have a line switch installed so that on site personnel can switch the outside telephone line between the data modem and the digital telephone system cabinet when you are going to perform remote programming.) 5. Refer to the user’s manual for the modem, and program the modem to automatically answer after the first ring. 6. Interface the PC with the modem at the programming site per the user’s manuals for the equipment be used. 7. Establish a communications link for programming the system from a remote site. ·If you have had a line switch installed at the customer site, call someone there and ask them to set it for modem operation. ·After the outside line is connected to the modem, make the data link between the originating and the remote modems, and perform programming from your remote site just as if the PC was connected directly to the system.

If you experience difficulty in establishing a communications path between your PC, modems, and the digital telephone system, note the suggestions that are listed below. ·Confirm that the modems are wired correctly. Be sure RD, TD, and SG are connected to the system’s serial data connection. Reverse connections at pins 2 and 3 if necessary. Sometimes you must strap pin 4 to 5, or pin 6 to 7, or pin 6 to 8 to 20 in the modem wiring. Check the modem’s installation manual for this requirement. Also check the manual for any additional wiring connections. ·Use a breakout box data tester to troubleshoot the data communications lines. ·Be sure that your modem has: auto-answer capability, DTR override, and CD override and that the Result Codes, On-Line Echo, Off-Line Echo, and Flow Control are disabled. Plus, make sure that you have enabled the modem’s auto-answer feature. The way to do this is to program an initialization string into the modem. A typical initialization string that uses generic modem AT Commands for connection to a telephone system’s serial data port is as follows: AT E0 F1 L2 Q1 S0=0 &C0 &D0 &K0 &W0 &Y0.Remember, this is a typical initialization string—not all modems will respond to it. You should refer to your modem’s instruction manual if you have difficulty.

2.13 Using The Music Interface If music is to be part of the system, connect a customer-provided music source to the common equipment music interface jack (phono jack) provided for this purpose. The impedance of this input is approximately 500W. Use the volume control on the music source to adjust the audio level of the music as required.
