the connection moment- to- moment. A certain amount of fluctuation is normal. However, if the readings stay below the line on the meter, you should hang up and redial as soon as convenient.

The system monitors the quality of the connection in each direction, and will prompt you if the connection has become unstable. You will have the option of "retraining" the modem or shifting to "phone" mode should this happen.

This default display will appear after the system has been left idle for 120 seconds.

POTS Connection Status (see section 3.1.2 for ISDN Connection status)

The connection status indicates the status of the line as follows:

On Hook - POTS mode idle

Off hook - Line is in use

Modem Detected - Modem carrier has been detected and modem training begun

Connecting. - Modem "handshake start"

Connecting.. - Modem "Ranging" stage is complete

Connecting… - Modem "Training" stage complete

Connect - Modem connection is operational

Connect Lock - Modem connection is operational and aacPlus decoder has valid data

Renegotiation Request - Far end has authorized modem re- negotiation. Audio will be re- established in 3- 5 seconds. Or, far end has dropped the call. Or, modem operation is no longer possible, and system will revert to Phone mode.

Retrain Request - Modem connection will be re- negotiated.

Modem Lost Sync - Modem connection has been lost; unit reverting to phone mode

Warning Dialogues

In a few cases, the Xport will warn the operator about status of the modem connection.

Marginal Performance – This indicates that the modem has detected marginal conditions that could cause dropouts or instability. Often the problem is transient, and you can choose “IGNORE”. If you see the dialogue more than once in a 10 minute period you may wish to choose “RETRAIN” or to redial during a break in programming (Retrain will cause a short 5-6 second gap in audio). If you cannot take a break, you can choose “PHONE” mode which will seamlessly switch to the telephone quality mode until you can redial.

Bit Rate Too Low…Falling back to Phone Mode - The modem is unable to negotiate an acceptable connection and therefore the connection has been established in “Phone” mode. You may wish to try redialing.

Unacceptable Modem Performance…Falling back to Phone Mode – The modem connection has failed and therefore the connection has been converted to “Phone” mode. You should redial when convenient.
