What Is a Fractional Channelized Card?
Currently, fractional channelized cards refer to the 1E1T1-F, 2E1T1-F, 4E1T1-F, and 8E1T1-F cards.
The transmission line of a fractional channelized card is divided into 32 timeslots that are numbered 0 through 31. In fractional channelized mode, timeslot 0 is used to transmit synchronous information, and other timeslots can be bundled into a channel set.
