Description

ABSTRACT:
A method and apparatus are disclosed for bypassing a first RF broadband amplifier in a CATV network so as to permit substitution of a second broadband amplifier for the first amplifier to permit repair, replacement and/or analysis of the bypassed first RF amplifier. A switching circuit is employed to rapidly substitute the second amplifier for the first amplifier and to reinsert the repaired of replaced first amplifier in the CATV network following maintenance thereof. Bypassing of the first amplifier and utilization of the second amplifier in its stead allows maintenance to be performed on the first amplifier without disruption of service to the portion of the network downstream of the first amplifier.
