LMF Software
The Local Maintenance Facility (LMF) application program is a
graphical user interface (GUI)–based software tool. This product is
specifically designed to provide cellular communications field personnel
with the capability to support the following CDMA Base Transceiver
Station (BTS) operations:
S Installation
S Maintenance
S Calibration
S Optimization
Ethernet LAN Transceiver
S PCMCIA Ethernet Adpater + Ethernet UTP Adapter
3COM Model – Etherlink III 3C589B
10BaseT/10Base2 Converter
S Transition Engineering Model E–CX–TBT–03 10BaseT/10Base2
Converter (or equivalent)
NOTE
Xircom Model PE3–10B2 or its equivalent can also be used to
interface the LMF Ethernet connection to the frame.
Ethernet LAN External In/Out Port Adapter
Trompeter Electronics, Inc., ADBJ20–E1–PL75 or equivalent BNC (F)
to TRB (M) adapter is required if it is necessary to connect the LMF
computer to the LAN external interface triaxial connectors located in the
power entry compartment.
RS–232 to GPIB interface
S National Instruments GPIB–232–CT with Motorola CGDSEDN04X
RS232 serial cable or equivalent; used to interface the LMF to the test
equipment.
S A standard RS–232 cable can be used with the modifications shown in
Figure 1-1.
NOTE
Pin 8 (CTS) does not have to be jumpered/shorted to the others
as it is a driver output. The DTR is already a driver output
signal. The other pins are to receivers. Short pins 7, 1, 4, 6 on
each cable end.
