Telcos need to provision additional feeder/distribution lines to accommodate serving-area-density-growth, along with the critical initiative of DSL deployment.
The 4220F2KF, 4220G2K and 4230G2K expansion cabinets expand existing 4220F/G and 4230G cabinets without replacing the installed cabinet. The essential base, frames and vertical ends are left in place, without timeconsuming replacement. New extensions are added to existing verticals, frame extensions are added to the existing SS6 frames, and new doors are installed.
Additionally, the cap is reused. New back panels are installed on F cabinets.
