The Cisco BWX 8303 provides three 10-MHz and three 1-PPS signals at the front panel, each
isolated and short-circuit-protected from the other two. One Cisco BWX 8303 provides the required
reference signals for three BWX 8300 or BWX 2300 Series Basestations; only a single BWX 8303
is required at a tri-sectored site.
The Cisco BWX 8303 package includes:
●
One GPS antenna
●
One lightning arrestor
●
Three pairs of color-coded BNC cables (2 meters)
●
One Ethernet cable (6 feet)
●
AC unit with AC cord, DC unit with one pair of AWG 18 wires (8 feet)
