CON
PU0
PU1
–
Send continuous binary zeros (96 kHz)
Send single binary zeros (2 kHz)
Connected to the S bus.
CON = 0:
Disconnected from S bus; an activation of the S/T line initiated
by the TE/LT-T is not possible: Info 1 cannot be transmitted.
An activation initiated by the network (reception of Info2/Info4) is still
possible.
CON = 1: Connected to the S bus; normal operation, transmission of Info 1
(upon an ARU command) is possible.
Pull-up pin for IDP0 (power saving option in TE mode, see chapter 2.4.2)
Pull-up pin for IDP1 (power saving option in TE mode, see chapter 2.4.2)
not used
X0 Mode Specific Pin (PEB 2086)
The X0 pin of the PEB 2085 ISAC-S which was intended for the CON-input (Connected to the
S-Bus) has been eliminated on PEB 2086. As a result, the C/I response DIS (Disconnect) will
not be generated.
