PA-8ILCE-A
ISDN Terminal Line Circuit
1. General Function
The PA-8ILCE-A (ILC) circuit card provides an interface between the system and a maximum of eight
ISDN BRI (Basic Rate Interface) terminals, allowing the system to use eight ISDN BRIs, which are made
up of two B channels at 64 kbps and one D channel at 16 kbps (2B+D
×
8), on the same bus. In addition,
this card supports D channel packet function. For this feature, however, available channels are seven
channels, ranging from No. 0 to No. 6.
