6.9.7 PDIU-DS Disassembly and Assembly
To set the jumper plugs (Pl - P9) on the PCB inside
the PDIU-DS for DCE or DTE operation, the PDIU-DS
must be disassembled. Disassemble the PDIU-DS' in
accordance with the following steps:
Subsection 6.9.8 paragraphs 2 - 6 provide tests for
five RCPI/DIU data call applications. These test
routines only check the data communications mode of
the RPCI-DI; they do not check the RPCI-DI API
mode. The telephone and port numbers used in these
figures are provided for explanation purposes only;
when actually testing, use port and telephone
numbers appropriate for the system.
4 If the PDIU-DS is connected to a DCE device,
set the plugs to the "B-C" position.
Note:
Do not cut PDIU-DS PERCEPTION jumper
wire for Strata DK280 installations.
Assembling the PDIU-DS
1. Position the back panel to the PCB (see
Figure 6-34).
2. Slide the back panel down into its side grooves.
3. Attach the bottom panel, and secure with the four
non-captive screws.
Each of these tests can be conducted with manual
dialing from a digital telephone's dialpad or AT dialing
from a personal computer's keyboard; however, only
the preferred method of dialing for application is
presented.
