3 DIGITAL TELEPHONE UPGRADES

3.00This section describes how to upgrade and configure 2000- and 1000-series Digital Tele- phones for features and options.

3.10Simultaneous Voice and Data Upgrade (PDIU-DI2 and PDIU-DI)

3.11Both the 2000- and 1000-series Digital Tele- phones can be upgraded with an integrated data interface unit to transmit and receive simultaneous voice and data calls. There are two versions of the integrated unit: the PDIU-DI and the PDIU-DI2. The 2000-series telephones can only be equipped with a PDIU-DI2, and the 1000-series telephones can only be equipped with a PDIU-DI. Asynchro- nous devices, such as personal computers (PC) and terminals, can be connected to the standard RS-232 connector of the PDIU-DI(2). Station us- ers are able to transmit and receive RS-232 data over the single wire pair of the PDIU-DI(2)-equipped telephone.

3.12Data calls can be manually dialed with a Data Call button and disconnected with a Data Release button on the telephone; or, data and voice calls can be dialed from the keyboard of the terminal or PC using standard "AT" commands. Digital telephones may also be assigned a Mo- dem button to reserve a modem or monitor mo- dem availability and status. Assign feature buttons to telephones with Program 39.

NOTES:

1.1000- and 2000-series Digital Telephones equipped with a PDIU-DI(2) cannot be wall-mounted or equipped with an Add- On-Module (ADM), or DVSU for OCA. A 2000-series digital telephone equipped

with a PDIU-DI2 can support an HHEU at the same time, but cannot support a DVSU. A 1000-series Digital Telephone equipped with a PDIU-DI cannot support an HHEU, ADM, or a DVSU for OCA.

2.PDKU1 circuits 1 ~ 7 only can support PDIU-DI(2)s, but all PDKU2 and base unit digital circuits, can support PDIU-DI(2)s.

3.13PDIU-DI(2) Installation. Install the integrated data interface unit (PDIU-DI for 1000-series and PDIU-DI2 for 2000-series) in accordance with the following steps:

1)Loosen the four captive screws securing the digital telephone base and remove it (Figure 6-1).

2)Refer to Figure 6-4 for 2000-series telephones or Figure 6-5 for 1000-series telephones, and insert the two integrated unit wire plugs into the connectors on the printed circuit board (PCB) in the telephone (observing the red wire for correct positioning).

3)Attach the integrated unit to the bottom of the telephone and secure with the four captive screws.

4)Remove the telephone number directory tray from the original telephone base and install it on the integrated unit telephone base. Bend the tray by squeezing its sides so it bows slightly to remove and re-install (Figure 6-4 or 6-5).

5)Check Table 8-D in Section 100-816-208; install 2-pair house cable (or external power) and 2-pair modular cord (supplied with PDIU- DI) if required to achieve maximum distance.
