* The Directory Number, Circuit-Switched Voice, Maximum B Channels, and Circuit-Switched Voice
Limit parameters should be set to 2 to allow both analog ports to be used simultaneously. If those
parameters are set to 1, the ISDN line can only place or receive one call at a time.
† Flexible Calling (FCO) provides 3-Way Calling (Call Conference), Hold, Drop, and Transfer from
analog equipment attached to the modem.
‡ Additional Call Offering (ACO) allows you to use incoming Dynamic Bandwidth Allocation (DBA) as
well as Call Waiting.
**Caller ID is necessary to employ the Call Logging feature. If you would like to have Call Logging,
you must order Caller ID. However, Caller ID itself, which requires an external device to monitor
incoming calls, is not supported.
††Call Forwarding allows you to forward calls to another telephone number.
