Global Positioning System (GPS) is a navigation aid system that uses signals from
satellites to calculate the actual position of a GPS-capable receiver. These signals are
not only used for determining the position of the receiver on Earth but also as a very
accurate time base. There are GPS receivers with 10-MHz clock frequency output
synchronized to a GPS satellite. The ACX Series router has a SubMiniature version B
(SMB) connector that can take 10-MHz sine-wave input from a GPS receiver. To configure
this 10-MHz clock from a GPS receiver as a candidate clock source for chassis
synchronization, include the
source ] hierarchy level.
NOTE: ACX500 routers do not require an external GPS receiver because the
GPS receiver is integrated into the system.
