Description
ISDN (Integrated Services Digital Network) is a digital network service providing digital audio
and control. In ISDN, control signaling is provided over a ‘D’ (data) channel and voice is
provided over a separate ‘B’ (Bearer) channel. Separating the signaling and content channels
provides more efficient control and bandwidth.
The ipLDK-60 supports the ISDN Primary Rate Interface (PRI). This interface provides high-
speed digital services for multiple bearer channels. In the ETSI standard, 30 bearer channels,
1 framing channel and a signaling channel are provided. In NA standards, 23 bearer channels
and 1 signaling channel is provided.
