Comcast is eliminating more than 1,000 positions across its cable and broadband units as part of an operational overhaul. More than 600 of the cuts are in Pennsylvania. The company says the changes are intended to make it more agile and competitive.

The layoffs come ahead of the planned spinoff of NBCUniversal and Sky media assets into a separate company. Comcast expects to record a restructuring charge of more than $1 billion in the fourth quarter. Its connectivity business has faced declining broadband and video subscriber numbers.
