• Manufacturer Part Number: psf2115
• Description: Isdn Adapter Circuit Ipac
• Manufacturer: ETC-unknow

An LED with pre-resistance may directly be connected to this pin and a low level is driven
on ACL as soon as the layer 1 is activated (see figure 34).
Figure 34
By default (PCFG:ACL=0) the state of layer 1 is indicated at pin ACL. If the automatic
indication of the activated layer 1 is not required, the state on pin ACL can also be
programmed by the host (see figure 35).
If PCFG:ACL=1 the LED on pin ACL can be switched on (PCFG:LED=1) and off
(PCFG:LED=0) by the host.
