Modem Summary

This screen provides the following:

Fields

Field Description
Channel Channel number. Possible values are 1-23 for PRI, 1-24 for Channelized T1, or 1-30 for E1. 
State Possible values are Idle, Inbound, Outbound, Busied Out, Inbound/Delayed Busy Out, and Outbound/Delayed Busy Out.

Idle means that nothing is happening on the channel at the moment.

Inbound means that the remote side initiated the connection. 

Outbound means that this system initiated the connection.

Busied Out means that a channel is in the busied out state.  

Inbound/Delayed Busy Out means that a channel with an inbound connection is in a delayed busy out condition. That is, when the connection ends the channel will be put in a busy out state. 

Outbound/Delayed Busy Out means that a channel with an outbound connection is in a delayed busy out condition.

Note: Resetting the modem will not clear a busy out condition.

Connect Time Duration of the current connection in days, hours, minutes and seconds
Current Tx/Rx Rate Rate at which the modem is transmitting and receiving expressed in bits per second
Max/Min Config Rate Maximum and minimum rate at which the modem on this channel will operate. This rate can be changed using AT commands on your adapter.
Byte Tx/Rx Count Byte count, both incoming and outgoing for this channel.
RTS/CTS/DTR/DSR/RI/DCD EIA-232 modem control signal state. A gray sphere (LED) indicates off, and blue sphere (LED) indicates on.

Note: No LED is present when the State is Idle.

Modulation Modulation technique the modem is using.
Busy Out/Clear Busy out means that the channel has been configured to not accept incoming calls. You use busy out to take a channel that is not working out of commission. When you do this, you can continue to use your adapter though it is only partially functioning. 

Choose Busy Out to busy out a channel (that is, to make it unusable) and Clear to clear a busy out condition on a channel (make it ready to handle calls again).
