How we work

01

Built from the ground up

We start with the physical network, so the layers above it work.

02

One accountable team

Cabling, IT, cloud, security and phones come from one provider, not five.

03

Local since 1982

We know the region, and we show up.

04

Security built in

Protection is part of how we run your network, not an add-on.

Local since 1982

DTC started in Southern California in 1982. We have been a NEC distributor since 1987 and support more than 2,500 phone systems. Our team knows the region, the buildings and the industries we serve.

That local history is why we can walk your space, test the cabling, review the network and answer the phone when something breaks.
