Why do we need to assign ip for the D channel ISDN-PRI

Why do we need to assign ip address to the D channel (signaling ) when we configure ISDN-PRI in the example below :

<quote>

Step 1:Specify the D channel of the first Primary Rate Interface (PRI):

AS01(config)# interface Serial 0:23

AS01(config-if)#

Step 2: Assign an IP address and subnet mask to the interface:

AS01(config-if)# ip address 172.16.254.253

You can assing one there, and / or on dialer interfaces. It depends on what you are doing.

These will be the address used by PPP when it runs on the B-channels.
