For example, you can use it for networking printers, PCs and other data equipment. Installing the 3-DCI Module(Figure 5-11) 1. Locate an available DDK connector in a station (B) block. 2. For the DDK connector chosen, cross-connect the associated wire pair from the A or B block to the cross-connect block. 3. Install a modular jack for the 3-DCI Module within six feet of the module. 4. Run one pair of 24 AWG station cable from the cross-con- nect block to the 3-DCI’s modular jack. 5. Terminate the station cable WHT/BLU - BLU/WHT leads to the RED and GRN lugs in the modular jack. 6.

Plug a line cord into the back of the 3-DCI Module and the module’s modular jack. 9. Plug the RS-232-C cables into the data device (e.g., PC serial port or serial SMDR printer.
5. Data and SMDR5-13 PROGRAMMING Basic Programming Note:For DCI units, the data (software) port number is the same as the extension’s port number. DCI Modules use the extension’s port number and the next two port num- bers for data (software) port numbers. 0503 - DCI Extension Number Assign an unused extension number to each DCI data (soft- ware) port. 1006 - Programming Function Keys Assign a data key (code 1029) at each keyset with a DCI unit. 1201 - DCI Setup For each of the DCI sub-types (1-10 set in Program 1202), set the values for the modem S-registers (Register Type 1) and X.25 packet switching (LAPB) registers (Register Type 2). 1202 - DCI Port Type Assign a DCI port type (1 for RS-232-C, 2 for Centronics, or 4 for DCE port [modem]) to each DCI data (software) port installed. Also, assign the sub-type (1-10 used in Program 1201) to each software port1206 - Initialize DCI After changing register values in Program 1201, be sure to use this program to initialize each DCI software port. You must ini- tialize a DCI software port before any changes made in Program 1201 will take effect. Programming for System and Alarm Reports 0007 - System Report Setup If the device connected to the DCI will also be for system reports, enter the DCI software port number as the system report port number. 0008 - Alarm Report Port Setup If the device connected to the DCI will also be for alarm reports, enter the DCI software port number as the alarm report port number. Refer to Data Communications Interface(DCI) in the Software Manual for additional details.

Data and SMDR 5-14 SOME TYPICAL DATA APPLICATIONS Non-Dedicated 3-DCI Modem Pooling Network (Figure 5-12) In this application, a data port on the 3-DCI connects to a modem which in turn connects to an available circuit on an ASTU PCB. To place a data call through this network, an extension user places a call from their PC or terminal using the following ATDT dial string: ATDT + (first 3-DCI data port’s extension number) + (code for accessing outside line) + (destination’s telephone num- ber) + Enter For example: ATDT 310 9 926 5400 Figure 5-12 A NON-DEDICATED 3-DCI MODEM POOL RS-232-C Cable (50’ max) 4-Conductor Line CordDCE to DCE Adaptor (P/N 88079) 120V AC Outlet Power Supply Modem B Block B Block 25-Pin RS-232-C Connector 13 12 11 10 9 8 7 6 5 4 3 2 1 25 24 23 22 21 20 19 18 17 16 15 14 DCE (3-DCI, DCI-A or Modem) Direction of Signal Flow ( output or input) DTE (PC or Printer) Description RS-232-C Pin Out Information RS-232-C Connector DCD RXD TXD DTR DSR RTS CTS GND 8 3 2 20 6 4 5 7 3DCI 625 Modular Jack 625 Modular JackStation Cable Station CableLine Cord To 16 DSTU Station Port 14 AWG to known Earth Ground BLK BLK YEL YEL RED REDGRN GRN BLU-WHT BLU-WHTWHT-BLU WHT-BLU One-Pair Cross-Connect One-Pair Cross-Connect DDK Connector DDK ConnectorTo digital station circuit on DSTU PCB To analog station circuit on ASTU PCB25-Pair DDK Installation Cable 25-Pair DDK Installation CableCross Connect Block Cross Connect Block 926 - 63
5. Data and SMDR5-15 SOME TYPICAL DATA APPLICATIONS Dedicated 3-DCI Modem Pooling (Figure 5-13) In this application, a data port on the 3-DCI connects to a modem, which in turn directly connects to a dedicated outside line. This application is also useful for incoming remote mainte- nance calls. To place a data call through this network, an exten- sion user places a call from their PC or terminal using the fol- lowing ATDT dial string: ATDT + (destination’s telephone number) + Enter For example: ATDT 1 203 926 5400 Figure 5-13 DEDICATED 3-DCI MODEM POOLING RS-232-C Cable (50’ max) Dedicated Modem CO Line DCE to DCE Adaptor (P/N 88079) 120V AC Outlet Power Supply Modem B Block 25-Pin RS-232-C Connector 13 12 11 10 9 8 7 6 5 4 3 2 1 25 24 23 22 21 20 19 18 17 16 15 14 DCE (3-DCI, DCI-A or Modem) Direction of Signal Flow ( output or input) DTE (PC or Printer) Description RS-232-C Pin Out Information RS-232-C Connector DCD RXD TXD DTR DSR RTS CTS GND 8 3 2 20 6 4 5 7 DCE 625 Modular JackStation Cable Line Cord To 16 DSTU Station Port 14 AWG to known Earth Ground BLK YEL RED GRN BLU-WHT WHT-BLU One-Pair Cross-Connect DDK ConnectorTo digital station circuit on DSTU PCB 25-Pair DDK Installation CableCross Connect Block 926 - 60
