Figure 26
In LT-T configurations, the DELIC receives the reference clock from the Central Office
via the IOM-2000 REFCLK line. The VIP selects the reference clock source via two
multiplexers. The source may be either one of the 8 VIP channels operated in LT-T mode
or the CLKIN pin when driving multiple cascaded VIPs on the IOM-2000.
