Avaya 6402D Guia Do Utilizador

For Generic 2 with universal modules, IDFs serve as secondary cross-connect points between
distribution cables and installation cables, which connect to the IOs. The IDFs usually are housed in
closets.  Along with the IDF, these closets frequently house the auxiliary power units that some

telephones require.

Although the design of an IDF depends upon the site, it should conform as closely as possible to the

Premises Distribution System (PDS) guidelines. The recommendations in this section supplement the
PDS guidelines, and are essential to the design of IDFs. Beyond these recommendations, use your
experience and best judgement in designing IDFs.

Use 110AB1-100 or 110AB1-300 terminal blocks for both the blue and white fields of the IDF.

If you are terminating fewer than 1200 cable pairs (riser and installation cables combined) on an IDF,
wall mount the terminal blocks directly (without a frame). If you are terminating more than 1200 pairs
on an IDF, use a wall-mounted type-1 frame (discussed earlier in this chapter under Recommended
Frames for Terminal Blocks.)

Remote groups are not supported by Generic 2 with universal modules.
