2. Connect the appropriate RS-232 cable between the modem and the PDIU-DS. Figure 12-29,
“RPCI-DI/PDIU-DI/PDIU-DS Modular Cable/RJ45 Adapter Connections” shows an example
PDIU-DS to “smart modem” RS-232 connection.
Important!
All 10 PDIU-DS EIA leads (signals) should be connected to the modem. Consult the
modem’s documentation for correct RS-232 pin requirements; the requirements may
vary with each manufacturer.
3. Connect the line side of the modem to a RDSU/RSTS, RSTUS2, or PESU standard telephone
circuit or a dedicated CO line (consult the modem’s documentation to install it to a CO line).
Chapter 10 – Universal Slot PCB Wiring provides station port wiring information.
4. Set the PDIU-DS DIP switch (SW1-1~4) for the desired application. (See Figures 12-31 and
12-32 .)
Note If the modem tracks carrier detect (DCD, AT&C1), SW1(4) should be On, and SW1(2)
should be Off when PDIU-DS is connected to a modem.
5. Configure the PDIU-DS to connect to an asynchronous modem using Programs 20, 21, 22, 31
and 33.
PDIU-DS Programming
Note
See the Strata DK Programming Manual for instructions and record sheets.
♦ Program 20
♦ LED 01: Should always be On for PDIU-DS ports
♦ LED 02: Should be On for PDIU-DS ports connected to modems, enabling the use of AT
commands and result codes when incoming calls are made from outside the system to
modems connected to PDIU-DSs.
♦ LED 03: Should be set On for PDIU-DS ports connected to modems.
♦ LED 04: Should always be On for PDIU-DS ports.
♦ LED 05: Should be Off if the system is installed behind a PBX/Centrex that uses access
codes to place outgoing trunk calls.
♦ LED 06: Should be Off for DIUs connected to modems. The modem cable must be
modified per
Figure 12-29 or Figure 12-37 , or the PDIU-DS internal jumper plugs must be
set per the instructions in the DKi Admin/DKi Backup User Guide .
♦ LEDs 17~20: Data security groups can be used to allow or deny digital telephones
equipped with PDIU-DIs access to the PDIU-DS ports connected to a modem. DIU
stations can only make data calls to DIUs in the same data security group.
♦ Program 21: For each PDIU-DS/modem pair, assign the digital, RSTU2, RDSU/RSTS, and
PESU ports that will be connected to the PDIU-DS and modem, respectively.
♦ Program 22/33: If more than one modem/PDIU-DS pair is configured as a system modem
pool, the PDIU-DSs should be set to hunt each other in Program 22. The modem RSTU,
PSTU, RDSU/RSTS, or PESU ports should be set to hunt each other in Program 33.
♦ Program 31: LED 18 should be turned On for all RSTU2, RDSU/RSTS, or PESU station ports
that are connected to modems. This provides data security by preventing executive or privacy
override of modem calls.
