The FBHDC allows use of adjacent channels for GSM and IDEN and W-CDMA.It also offers
unrestricted GSM frequency hopping. Channel tuning is not required, however band tuning is.
Four 20dB or 40dB attenuators are provided with each FBHDC. The attenuators allow a direct
or coupled connection from the BTS while restricting the FBHDC input range. 20dB is used
when coupled and 40dB is used when directly connected.
