MX410 DATA PATH BLOCK DIAGRAM
As shown in Figure 3-1, the MX410 contains a 1/0 cross connect that allows DS0s to be
mapped between four DS1s (twelve DS1s on the MX412), four PPP ports, and a V.35 port.
Refer to “PPP BCP/IPCP Menu” on page 5-38 for more information about using PPP.
Any DS0 in DS1 1 can be mapped to any DS0 in DS1 1-4, any PPP port, or the V.35 port.
Any unmapped DS0 in a DS1 is filled with all ones. Therefore, if an entire T1 is unmapped,
framed all ones are sent.
The 1/0 cross-connect default mapping of the DS1s is odd to even ports (for example, DS1 1 is
mapped to DS1 2). By default, DS0s are not dropped to the PPP or V.35 ports.
