The MUNICH256 in 28-port mode supports T1, E1 and unchannelized frame structures
on the serial side. Each receive port has a receive data input RD(x) and the
corresponding receive clock input RCLK(x). In transmit direction each port consists of
the transmit data output TD(x) and the transmit clock input TCLK(x). In T1 and E1 mode
a clock gap marks the beginning of a frame. The timing of the unchannelized mode is
identical to the 16-port mode.
