MX3216 DATA PATH BLOCK DIAGRAM
The MX3216 contains a 3/1 cross-connect that allows DS1s to be mapped between two DS3s,
eight DSX-1 ports, and two expansion slots in the MX3 chassis (see

Each expansion slot has four DS1s available. The expansion slots share two of the DS1s (see
Figure
3-1). How the DS1s are used depends on the module installed. For example, the
MX3RMM only uses two DS1s.
Any DS1 in DS3 A can be mapped to any DS1 in DS3 B, and vice versa. Any DSX-1 port can
be mapped to any DS1 in DS3 A or DS3 B. The expansion slot DS1s can be mapped to any
DS1 in DS3 A or DS3 B and to any other expansion slot DS1. In addition, any two DSX-1
ports can be mapped to expansion slot DS1s.
Any unmapped DS1 in a DS3 is filled with AIS (unframed All Ones). Any unmapped DSX-1
port is disabled with the transmit drivers tri-stated and no alarms reported.
The default mapping of the 3/1 cross-connect is for all the DS1s to pass straight through from
one DS3 to the other. No DS1s are dropped to the DSX-1 ports or the expansion slots. If
needed, re-establish the default mapping through selecting the Restore Map to Factory
