Page 4-8
 2005, ADC Telecommunications, Inc.
In order to balance the reverse path the following procedure is followed:
1. Measure or calculate cable loss from BIM Output to BTS input
2. Enter cable loss value (forward and reverse) into the transceptTenantForwardCableLoss
and transceptTenantReverseCable Loss fields of the Tenant OAM MIB field for this
Tenant Sector
3. Enter reverse gain setting (-10 to +10 dB, typically +10 dBm) into the
transceptTenantReverseGain field of the Tenant OAM MIB for this Tenant Sector.
3.3 RGC Changes
In a duplexed configuration, the RGC gain is set from +10dB to -10dB (see Figure 4-5?). In a
non duplexed configuration (Figure 4-6?), the WSP would need the uplink set for 21 dB of
gain with consideration give to:
• No 20 dB high power pad
• Cable loss from the BIM to BIP
• BIP losses.
The BIM to BIP losses must be measured by the installer and the result entered into the
TENANT MIB.
3.4 FGC Changes
FGC requires that the output power of the EBTS is known and the losses from the EBTS to the
input to the BIM be measured and entered into the Tenant MIB.
3.5 Functional RAN Call Verification
At the completion of BTS integration, that the coverage area is driven to insure all RANs are
functional. Recommended In order to verify RAN calls the following procedure is followed
1. Place calls on all RF channels supported by targeted RAN sector
2. Ensure hand-offs between RANs and RAN to tower are functional.
