The answer is an Entrance Facility.
The entrance room or entrance facility is the location for the access provider equipment and demarcation points. This is the area of a building where carrier and private network enter the building. Whenever we talk about a WAN connection, we are talking about a geographically distributed private network that interconnects multiple LANs. Therefore, it is safe to say that you should take the technician to the entrance facility since it is the point at which the outdoor plant cable (WAN) connects with the building’s backbone cable (LAN).
