Installation of the Desk Console and 
Cable Connection
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
Attendant 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.
 LT cable Pin Assignment
Pins are assigned as follows for PA-CS33 card.

INSTALLATION PROCEDURE
Note:
When replacing Attendant Console with DESK CONSOLE, follow the procedure below:
1 Turn OFF the PWR card in the PIM.
2 Remove installation cables connected to ATT0, ATT1 and LT connectors on the ATT TERM.
3 Remove installation cables connected to the following connectors:
RLT connector on the ATT TERM
ATI0 and LT5, ATI1 and LT11 connectors on the PIM
4 Install DESK CONSOLE using the LT connector on the ATT TERM.
5 Turn ON the PWR card in the PIM.

INSTALLATION PROCEDURE
2. CALCULATION OF THE DISTANCE BETWEEN THE ATI CIRCUIT CARD AND MODULAR ROSETTE
The distance M in Figure 016-3 is determined by the Direct-Current resistance of power supply cables (–48V and
GND). Note that the maximum resistance is 26 
Ω as shown in the following formula:
M = a + b + c 
≤ 26 
Ω
M: Maximum Direct–Current resistance between the ATI circuit card and Modular Rosette
a: Direct-Current resistance of power supply cables (–48V and GND) in the range of A
b: Direct-Current resistance of power supply cables (–48V and GND) in the range of B
c: Direct-Current resistance of power supply cables (–48V and GND) in the range of C
Example of Calculation
a, b, and c are calculated by the following formula:
Note:You are not required to use cable lengths in meters in the following formulae. You may use cable lengths in
feet, yards, or whatever unit you prefer. However, the units of resistance you use must match the units of
length you use. For example, if you use distance in feet, you must also use DC resistance per foot.
u: Direct-Current resistance per meter in the range of A (
Ω/m)
v: Direct-Current resistance per meter in the range of B (
Ω/m)
w: Direct-Current resistance per meter in the range of C (
Ω/m)
x: Cable length (m) in the range of A
y: Cable length (m) in the range of B
z: Cable length (m) in the range of C
