Wideband Column Switch Components
The OC-48 wideband switch in TUPP 2488 caters for multicast applications and thus requires 8
OC-12 MSUs in each direction and a 16*OC-12 input CCB. The switching system appears as in
Figure 43. Note that the muxes out of the Egress MSUs select (on a per column basis) which of
the OC-12 MSUs are sending information onto the OC-12 egress busses. These muxes are
controlled by the EMSU_SEL lines which are set up in the MSU configuration RAMs.
