The total wire path length from the data outlet to the MTR or TER termination point must not exceed 295 feet (90 meters). This is important to meet Ethernet requirements of IEEE 802.3. Please note that in most cases the TER that houses network electronics will service both the voice and data jacks on the floor where it is located. This must be considered when determining adherence to the maximum length for the data outlet wiring.
Each end of all cables will be labeled at their termination locations.
In newly constructed buildings communications outlets will be labeled with the room numbers as provided on the construction documents. The format is as follows:
Building Acronym Room Number – Connection Count Type Connection
Example: DBB101-1D or DBB101-1V
Where DBB is the Building Acronym, 101 is the Room Number – Connection Count is 1 and identifies the first connection in the room and Type Connection D identifies the connection as a data connection. V is to be used for analog voice connections.
The number of connections in a room is determined by standing at the opening to the room then start counting connections beginning with the number 1 from the immediate left wall following in a clockwise direction around the room.
