The Comtest Bonded Splitters are a full dual low-pass filter designed to enable up to two POTS services to coexist with two-line bonded ADSL2+ or VDSL2 data signals up to 30MHz. Bonded Filters simplify and reduce installation time of bonded services in customer’s home or business; while filtering both pairs, thus supporting an additional POTS line or billing service on the second pair. Treating the DSL signals on the second pair maximizes data rates to take full advantage of the bonded xDSL service.
