4. Cabling of T1 cables in the cabinet
The T1 lightning arrester is equipped with two T1 cables. Before connecting the
T1 lightning arrester with the cabinet, label the T1 cables at the position near the
connectors with “OUT#” or “IN#” (#=1, 2, 3 or 4”).
“OUT#” and “IN#” should be the same as “OUT” or “IN” marked on the cable
outlets at the back of the lightning arrester. When installing the T1 lightning
arrester, ensure that the serial number “#” marked on the T1 cables is consistent
with the silk-screen at the bottom of the BDM and the cabinet.
To facilitate recabling the T1 cables connected with the lightning arrester, these
T1 cables should be laid along the upper edge inside the cabinet, and the cable
tie bases should be installed at the positions convenient for uninstallation. See
Fig. 11-8. It is suggested to bundle the T1 cables with cable ties every 150mm.

If a micro-BTS need be configured as a remote station, an OIM should be added on the
BDM of the micro-BTS.
See Fig. 10.3-4 for the corresponding relations between the OIM expansion slots in
BDM and the sectors.
