7.6
The following table shows the necessary configuration for the Digital Clock Interface Mode (DCIM), see ITU-T
G.703 11/2001, chapter 13. The receive clock at RL1/RL2 (2.048 MHz) is supported at multi function port RPC.
The transmit clock at FCLKX (2.048 MHz) is transmitted at XL1/XL2.
DCIM mode is standardized only for 2.048 MHz (E1 mode, MR1.PMOD = ´0´). The OctalLIU
1.544 MHz if MR1.PMOD = ´1´.
