on the ISWM backplane.
 EXCLK0/EXCLK1 connector Pin Assignment
Pins are assigned as follows on “EXCLK0/EXCLK1” connector. When clock is distributed from a digital inter-
face, use one pair of “DIUxxx” leads among a maximum of 4 inputs. DIU leads have the following precedence:
DIU0xx(High)-> DIU3xx(Low). Contrarily, to receive clock from an external high-stability oscillator, use “DC-
Sxx” leads.

This figure shows an example of distributing clock from a digital interface. This example also assumes that the
Digital Trunk POUT leads are used as the 1st clock distribution route.
Note 1:PLO has a maximum four inputs. DIU0xx leads are used for the 1st clock distribution routes. Thus,
DIU3xx leads are used for the 4th. The first input has the highest priority.
Note 2:The connection is required for a dual PLO system.

Cable running Referring to Figures 015-2 through 015-5, run the cables 
between each DESK CONSOLE and its Modular Block 
(Jack), and between the Modular Blocks and the MDF.
Protect the cables by using cable ducts, etc.
Termination of cables Referring to Figures 015-2 through 015-5 terminate the 
installed cables to the MDF and the Modular Blocks.
Check the terminal locations on 
the Module Group side of the 
MDF.Referring to Port Accommodation sheet and description of PA-
CS33 card in the “Circuit Card Manual,” identify the lead 
names for the card and the terminal locations of the leads.
Cross Connection Referring to Figures 015-2 and 015-5, provide the necessary 
cross connection at the DESK CONSOLE side and the PBX 
side.
Mounting of Headset (Optional) Referring to Figure 015-6, mount optional Headset on DESK 
CONSOLE.

To connect DESK CONSOLE(s), the PA-CS33 card is used as the interface card. The card may be mounted
in slot No.12 or in slot No.23. The leads appear on LT5 and LT11 respectively. However, when replacing At-
tendant Console with DESK CONSOLE, the leads appear on the LT connector on the ATT TERM (See 
Note
on the next page).
 PA-CS33(ATI) mounting slots
PA-CS33(ATI) card may be mounted in
slots 12 and/or 23.
 LT cable connectors
Use LT5 connector when the PA-CS33 card
is mounted in slot 12. When the card 
is mounted in slot 23, use LT11 connector.
