the selected DS1 port (1-4 on the MX410 and 1-12 on the MX412).
Figure 5-10. Primary Timing Mode Menu
The Primary Timing Mode menu options are shown in Table 5-7 .
CAUTION
The entire MX410/MX412 is timed from a single source and all
transmitters are synchronized. Any device attached to the MX410/
MX412 should be placed in loop or line timing mode, unless it is
providing timing. If an attached device is providing timing, the
MX410/MX412 must be configured to use this interface as its pri-
mary timing source. If the MX410/MX412 is set for internal timing,
all devices connected to it must be set to loop or line timing.
