Note:When replacing Attendant Console with DESK CONSOLE, follow the procedure below:
(a) Turn OFF the PWR card in the PIM.
(b) Remove installation cables connected to ATT0, ATT1 and LT connectors on the ATT TERM.
(c) Remove installation cables connected to the following connectors:
 RLT connector on the ATT TERM
 ATI0 and LT5, ATI1 and LT11 connectors on the PIM
(d) Install DESK CONSOLE using the LT connector on the ATT TERM.
(e) Turn ON the PWR card in the PIM.

Calculation of the distance between the ATI circuit card and Modular Rosette
The distance M in Figure 015-3 is determined according to 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 formulae:
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

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.
