MDF/lDF DESIGN: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES
INSERT LABELS
Insert labels identify the origins of cables that terminate on the MDF and on the IDFs. The labels are
color-coded and come in sheets with 18 labels per sheet. The labels slip into the ½-in. by 8-in. clear
plastic holders that snap between the horizontal index strips of the terminal blocks. Many different
types of labels are available.
The color coding of the labels indicates the source of terminating leads as follows:
●
Green: network services (CO trunks)
●
Purple: equipment ports
●
Yellow: auxiliary cabinet and miscellaneous switch cables
●
Blue: IOs
●
Gray: connections between IDFs
●
White: connections between the MDF and the IDFs
The color coding of the labels is also used to set off specific fields on the MDF and IDFs as follows:
●
O n t h e M D F :
— Green for the network services (CO trunks) field
— Y e l l o w f o r t h e a u x i l i a r y f i e l d
— Purple for the equipment ports field
— White for the building distribution field (cables coming from the IDFs)
— Blue for the installation field
●
O n t h e I D F s :
— White for the building distribution field (cables coming from the MDF)
— Blue for the IO field
— Gray for the tie cable field (cables coming from another IDF)
— Purple for remote equipment ports terminated at the IDF
In addition to being color coded, the labels are printed in various pair combinations to match the
pairings that can occur on the fields. They also contain preprinted circuit numbers and space to fill in
the module (0-31), cabinet (0), carrier (0-2), and port slot numbers (1-20) at the time of installation.
