 An alarm indicates that a port is not available for some reason. Thus it
 is probably not a good idea to try to call out through it.

 Red Alarm
 ^^^^^^^^^
-Your T1/E1 port will go into red alarm when it maintain synchronization
-with the remote switch.  A red alarm typically indicates either a
-physical wiring problem, loss of connectivity, or a framing and/or
-line-coding mismatch with the remote switch.  When your T1/E1 port loses
-sync, it will transmit a yellow alarm to the remote switch to indicate
-that it's having a problem receiving signal from the remore switch.

 The easy way to remember this is that the R in red stands for "right

 (AIS -- Alarm Indication Signal)
 
-Your T1/E1 port will go into blue alarm when it receives all unframed 1s

-indicate that the remote switch is having problems with it's upstream
-connection.  As far as I know, dahdi_tool/zttool and Asterisk don't
