13b-7.1 General requirements Cables shall be labeled at all termination points, splices boxes, PETs, and manholes/hand holes. If there is a splice box in the manhole/hand hole the cables shall be labeled between the splice and the end wall on both sides of a splice canister. For un-spliced (straight through) cables, a label is required at each end where the cable enters and exits the manhole. For cables that penetrate walls or floors a label is required on at least one side of the penetration. Labels will be mechanically generated and not hand written and shall be water resistant.

13b-7.2 LAN cables LAN cables shall be labeled both at the communication jack and in the telecommunication room.

That means as follows:

- 1= Number of the telecommunication room

- 1= Number of the telecommunication rack

- A01=Number of the patch panel and number of door

Note: Telecommunication rooms (TR) are numbered progressively; the first telecommunication room, the one in which the cables coming from the outside of the building are connected, is the number 1 (TR1). In case there are further telecommunication rooms, they will be numbered as TR2, TR3, etc.
