Charter Communications is promising its Southern California customers it won’t bungle the transition from Time Warner Cable to Charter Communications like Frontier Communications did with former Verizon customers.

“We purchased all of Time Warner Cable and Bright House Networks. With this transaction we acquired everything,” company spokesman Justin Venech said. “We’re able to take more time in the integration process and not rush to make changes.”

Charter will take up to 18 months to make its presence fully known in areas formerly served by Time Warner Cable, and then primarily under its brand name known as Spectrum.

Time Warner Cable customers will be able to keep their current service and packages even after the transition, at least for a while.

But not all customers are happy about Charter’s slow transition plans. Customers waiting for Time Warner Cable Maxx upgrades, some already in progress, may be out of luck. Charter’s new management team put an indefinite hold on Time Warner’s more aggressive upgrade plans in favor of Charter’s much more modest commitment to offer customers two broadband speed tiers – 60 and 100Mbps over the next 18 months. Customers in the northeast and midwest have been told there are no longer any definitive dates for the introduction of Maxx, which offers free speed upgrades up to 300Mbps.

Almost all of Time Warner Cable’s executive management has been escorted out of the company’s Manhattan headquarters, severance pay and benefits in hand. In fact, Charter plans to abandon Time Warner Cable’s Manhattan headquarters altogether and shift top management to its plush Connecticut office. Most workers will be reassigned to other locations yet to be announced, some possibly upstate.

Charter has already begun repricing service and packages that will resemble Spectrum offerings, at least for new customers across Time Warner Cable and Bright House territories. The packages will not carry the Spectrum brand just yet, however.
