MDF/IDF DESIGN: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES
When 4-pair installation cables and spare cables or cables dedicated to systems terminated on the MDF
other than Generic 2 with universal modules are terminated on the MDF, add two more fields to the
arrangement.
Port Fields and Short Jumper Lengths. For most installations, combine the line and trunk fields to
accommodate the CPC, as shown in figure 7-8, Combined Trunk and Line Ports.
Some fields may be better arranged with separated port and trunk blocks, as shown in figure 7-9,
Separated Trunk and Line Ports. Use space for port trunks sparingly in large installations.
