 When the PA-SDTA and PA-SDTB cards are mounted in the 4-IMG system
(a) When to use the 34PH MT24 TSW CA-x cable:
When the PA-SDTA and PA-SDTB cards are mounted in the 4-IMG system, the 34PH MT24 TSW 
CA-x cable is used for connection between the PA-SDTB and TSW. The type of cable varies 
depending on the mounting location of the PA-SDTA/PA-SDTB card(s).

Example: When the PA-SDTA and PA-SDTB circuit cards are mounted in PIM3 of IMG0, and MG07 (PIM2 andPIM3 of IMG3) is assigned for the SDT interface, the type of cable and connector locations are as shown
in the following figure. The mounting location of PA-SDTA/PA-SDTB circuit card has no relationship
to the time slots assigned for the SDT interface so the PA-SDTA and PA-SDTB circuit cards can be
mounted in any PIM.
