SIR card connectors and wiring
The side interface right (SIR) card connector field (see Figure 13-31 on page
13-46) is located on the right-hand side of the ABM shelf.
The SIR connectors provide high-speed digital cable links to the CDS for VF
lines. The VT and D links are numbered from the bottom left line drawer (1)
to the bottom right line drawer in sequence to the top line shelf. This is in the
same numbering sequence as the VF lines, that is, from the bottom shelf left
drawer for line one (1) to the top shelf right drawer for line six hundred
seventy-two (672).
The VT and D 44-Pin D-sub connectors and the designations for each is shown
in Table 13-11 on page 13-45.
Figure 13-31 on page 13-46 shows the SIR card connector layout.
Figure 13-32 on page 13-47 shows the 44-Pin D-sub connector pin locations
and layout.
Figure 13-33 on page 13-48 shows the SIR card connector wiring block
diagram for the access link cabling.
