SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
6. Place two HSD Swift64 ISDN voice calls (one call from each channel card)
and while both calls are connected, place two Aero H/H+ voice calls.
The Aero Watts value should initially increase to a value of 8 to 10 W and
then stabilize to lower watt value of 1.5 to 2.5 W when the call has stabilized.
Refer to Figure 4–43 and Figure 4–44.
7. Toggle OFF report 78. (Press = , then type 78. Report 78 appears as “OFF”).
(e) Verifying System Operation when “In-Call” (Report 78)
The values shown in the following examples of the HSD Maintenance Port Utility,
Report 78, are derived from an HCM system operating with a 12 dBW gain and
2.5 dBW HPA-to-antenna-loss and assumes good beam coverage.
