Backup number

Another use for the Optional Second Number item is for storing a backup number in case a connection cannot be made using the primary number. For example, if calling the primary number returns a busy signal, the Netopia Router will attempt to use the secondary number stored in Optional Second Number. If a connection also cannot be made using the secondary number, see the event history to determine the problem and its solution. See Appendix E, “Leased line and ISDN Events”, for more information.

If the remote network's directory number is part of a hunt group, a second directory number may not be necessary to make a successful connection using two B-channels.

Dynamic B-channel usage

If the B-Channel Usage item in a connection profile’s PPP/MP Options screen is set to Dynamic or 2 B, Pre-emptible, one or both B channels may be in use at any time during a call made with that connection profile. Use of the second B-channel depends on traffic volume.

In addition, one of the B-channels may be relinquished if there is an incoming call, or if a second outgoing connection is made using another connection profile.

The ability to allow incoming calls when both B-channels are in use depends on the type of switch protocol on the local ISDN line, and how that line is provisioned (configured). Some types of switch protocols never allow incoming calls when both B-channels are in use. Switch protocols that do allow incoming calls must have the additional call offering (ACO) parameter turned on for data. ACO for data is off by default.
