3.9 Interconnecting Cabling
Site planning requires true single point grounding. The Telco entrance and Telco
termination board should be located as close to the transmission line entry and
AC service entrance as possible. This enables the individual
ground leads to
bond to a single point, with the least amount of distance between the ground
leads.
3.9.1 T1
T1 lines are used to connect the RadioFrame System with the Mobile Switching
Center (MSC). Each RFN customer iDEN/802.11b RFS site is typically fed with a
single T1 line, and subsequently protected with a surge suppressor. The
suppressor is located between the "smart jack" (maintained by the local
telephone company) and the Channel Service Unit (CSU). The suppressor
should be grounded downward directly to the master ground bus (MGB) using a
#6 AWG green wire.
The Telco board and the MGB should be mounted adjacent to each other on the
same wall (the coax ground and power ground should also be at this same
