The layer underneath the phone system
Four decades in, BT-SA occupies a specific position: it is the company that puts the cabling, racks, UPS, cooling and access control into a building so that somebody else’s phone system and internet service can run on it. That is genuinely useful if you are fitting out offices, building a data centre or standardising cabling across sites, and it is why the client list runs to banks, mines and manufacturers. It is not what you want if you are shopping for extensions, call rates or a hosted PBX — for that, compare the phone system providers WhichVoIP has verified, then let BT-SA or a firm like it handle the cabling behind it.
Who BT-SA is a fit for
- Businesses fitting out or recabling offices to a certified structured-cabling standard
- Data centre and server room projects needing cooling, backup power and containment together
- Multi-site organisations wanting one maintenance contract across cabling, power and security
