Introduction
PRODUCT OVERVIEW
The MX410/MX412 delivers full DS0 control to service locations, allowing carriers full utili-
zation of DS1 bandwidth. The MX410 interfaces to four long-haul outside plant protected
DS1s via RJ-48 connectors, while the MX412 interfaces to 12 DS1s. Data and management on
the DS1s can be cross connected on a non-blocking per-DS0 basis to any DS1, V.35 port, and
four PPP ports. Data Ethernet connectivity is provided via four PPP connections used for
Ethernet network extension throughout the network and Telnet-based terminal server ports.
The MX410 houses up to two hot-swappable Power Supply Units (PSU) that provide power
redundancy when two units are deployed. At least one MX410 PSU (P/N 1189501L1) must be
inserted into the MX410 for the MX410 to function. The MX412 has an internal PSU.
See Figure 1-1 and Figure 1-2 on page 1-3 for overview diagrams.
