Coax size, 1/2" or 7/8", is determined by the overall length of the coax run (the
distance in feet from the GPS antenna to the top of the equipment rack
containing the iSC-3). The maximum run length for using 50ohm 1/2" coax is
166'. The maximum run length for using 50ohm 7/8" coax is 290'.

Channel Service Unit (CSU)
The Channel Service Unit (CSU) provides the T1 connection between the iSC-3
and the telephone company that provides the T1 line. The CSU provides surge
protection to the T1 line and loop-back testing for the telephone company.

RadioFrame System (RFS)
The RadioFrame System is comprised of several components, which are
connected in a ‘tree’-style architecture (see the following illustration):
connected in a ‘tree’-style architecture (see the following illustration):
•
The Network Chassis Unit (NCU) acts as the sole connection point (i.e. the
‘root’) to all ACUs (and RFUs) which ‘branch’ off this ‘root’ chassis. The NCU
also connects to the iSC and the customer LAN.

Up to eight Airlink Chassis Units (ACUs) connect from the NCU and send
traffic, power and timing to the RFUs over standard CAT 5 wiring.

Up to seven iDEN RadioBlades (RBs) can be installed per RFU, and up to
three 802.11b RadioFrame Access Points (RAPs) per RFU; the combined
total is seven RBs/RAPs per RFU. Each iDEN RB and RAP provides a single
RF transceiver that supports iDEN or 802.11b (WLAN).
