BSC and the local BTS terminal. Therefore, site administrationship will be granted to

one side at a time.

When a site is installed and begins to run, BSC has the site administrationship by

before performing any operation at a BTS terminal.

When the operation is over, please release the site administrationship.

II. Access

Activate BTS terminal maintenance console, and select [Site/Site

Administrationship]. Click or in the popped up dialogue box
