Ordering
The circuit modules described in Section 2 can be ordered as spare parts
kits (K1-4). Table 8-A shows the contents of the kits along with the part
numbers to order modules individually.
Handling
The following guidelines describe an electrostatic discharge (ESD)
prevention method that is consistent with the proper handling and
protection of circuit packs in a central office or outside plant
environment. These guidelines satisfy the minimum requirements for all
three ESD-sensitive classifications (I, II, III) and, therefore, all circuit

Electrostatic Discharge Warning
Grounded antistatic wrist straps must be worn for all circuit pack
handling. The alligator clip connector of the wrist strap must be
connected to a bare metal frame ground. The wrist strap must
contact the skin and is not to be worn over clothing. At least once
every week of use, verify that the resistance between the wrist strap
and its connector plug is 1 milli ohm ± 10%. If a static-sensitive
pack has already been found faulty, do not ignore requirements for
handling static-sensitive packs. Continued mishandling may create
other, more serious, problems with the pack.
