4.19.8. DChanDesc (D Channel Identifier)

Description: The DChanDesc parameter is an ISDN parameter used to select the D channel that the B channels in the set will use. A value of 0 selects the default D channel. This parameter is ignored for T-1 CAS, clear channel and PDK protocols.

For example, on T-1 ISDN lines, DChanDesc is set to a value of 1 as follows:

defineBSet=10,1,1,23, 0,1,1,1,20,1, 1,1,3,23,0
defineBSet=20,2,1,23, 0,1,1,1,20,1, 1,1,3,23,0
defineBSet=30,3,1,23, 0,1,1,1,20,1, 1,1,3,23,0
defineBSet=40,4,1,23, 0,1,1,1,20,1, 1,1,3,23,0 

Values:

• 0 = Use default channel (24 for T-1, 16 for E-1)
• 1 to 24 (T-1)
• 1 to 30 (E-1)
