IMG 1010 - NFAS Examples

Both these examples below do not affect the already configured channels running calls. Both these scenarios show a single Channel Group called ISDN_Inbound. The IMG could also have separate Channels Groups with the 2 scenarios mentioned and get the same results.

Example 1: Multiple ISDN Circuits within the same ISDN Group

Step #1: Create 2 spans (Span 0, Span 1). The D-Channel is on span 0 and the first facility span is 1.

Step #2: Add another Facility (Span 2) to the ISDN Group.

Example 2: Multiple ISDN Groups

Step #1: Configure 2 spans (Span 0, Span 1). The D-Channel is on span 0 and the first facility span is 1.

Step #2: Add another Facility (span 2) to the new ISDN Group. This allows you to set attributes such as Bearer Capabilities and Network Type differently from the other ISDN Group.
