Figure 1-37. Interfacing Interleaved Highway to CX2839x (Frame Sync Externally Provided)
Each Interleaved highway interface carries four separate T1, E1, Fractional T1, or Fractional E1 style data streams
(32 8-bit timeslots per frame). The data streams are interleaved one timeslot at a time. T1 links are supported over
the Interleaved Highway interface, by mapping the 24 T1 timeslots (numbered 1-24) into the corresponding E1
timeslots. The remaining E1 timeslots, 0 and 25-31 are unused.
The interleaved highway mode can be selected on a per group of four link basis where the groups are as follows:
Input pins IHRxSync and IHTxSync are provided to indicate the first bit (MSB) of the first timeslot of the first data
stream, in the receive and transmit directions respectively. The streams are multiplexed in order of the lowest
numbered stream to highest number.
