I can't remember but... this also helps dialer pool-member number [priority priority] [min-link minimum] [max link maximum] - Assigns a physical interface to a dialer pool. priority priority - Sets the priority of the physical interface within the dialer pool (from 1 to 255). Interfaces with the highest priorities are selected first when dialing out. min-link minimum - Sets the minimum number of ISDN B channels on an interface reserved for this dialer pool (from 1 to 255). Used for dialer backup. max-link maximum - Sets the maximum number of ISDN B channels on an interface reserved for this dialer pool (from 1 to 255).
