2.1.2 Required Test Equipment, Jigs and Tools Table 2-2. Patch cord connection
For proper mechanical adjustment, the following test equip-
ment, jigs and tools are strongly recommended. Without
them, a long trial-and-error period would be necessary,
resulting in possible damage. In addition, general-purpose
tools and a metric hex key (obtain locally) are required.
