The system can use both B-channels for data until a call is initiated or received. When acall comes up, it may then drop back to a single B-channel for data, and reserve the other B-channelfor POTS use (such as voice or fax).The POTS service supports 3.1 Khz Audio or Speech service. This service guarantees the properchannel bandwidth in regard to the phone companies.Each of the two POTS ports may have either the same or different phone numbers. If each port hasits own number, each has its own data link allocated to it.POTS supports the alternate outbound and forward incoming call features. These features, if enabled,recognize when a second data link is available, and automatically uses it when its allocated datalink is busy. For example, in a one-person sales office, you could use the forward incoming feature toalways ring on the first line, which would attach to the telephone on your desk. However, if yourline were busy, the call would automatically be routed to the second line, which is attached to ananswering machine.To use the POTS interface, configure the following:• POTS devices• the POTS information including:the encoding standardthe POTS lines configuration information• per device POTS priority information
