clopez2007 creo que valdría la pena que busques el significado de cada una de las alertas, para que puedas determinar si agregas u omites alguna de ellas..
Te comparto lo que encontré en una búsqueda rápida en google, sin embargo, recomiendo que lo confirmes:
RED: Your T1/E1 port will go into red alarm when it cannot 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 remote switch.
YELLOW: remote alarm indication (RAI): Your T1/E1 port will go into yellow alarm when it receives a signal from the remote switch that the port on that remote switch is in red alarm. This essentially means that the remote switch is not able to maintain sync with you, or is not receiving your transmission.
