Description MDL is a channel formed by using the three C-bits in the fifth subframe in C-bit
framing. According to ANSI T1.107a, it is used to transmit three types of maintenance
messages, path, idle signal, and test signal, and its data frame format is LAPD.
At the startup of your router, MDL message detection and sending are disabled on
the CT3 interface and the default MDL message information applies.
