1. INTRODUCTION
The 86431 Power Unit is one of the family of u
nits in the GE Multilin’s
JungleMUX SONET and T1 Multiplexer (T1MX) digital transport/access systems
designed specifically for the requirements of the utility (Power, Transportation,
Pipelines, Oil & Gas, etc.) industry using optical fiber transmission.

There are two generations of Power Units for JungleMUX multiplexers; the old-

units implement completely different hardware solutions. The descriptions and
block diagrams for both generations of units are included.
Engineering documentation includes EAS schematics for all unit circuitry.

Product Color and Nomenclature
The JungleMUX product line has undergone a transition to a new colored
package. To distinguish between legacy gray and new black, a "B" prefix is
added to all black shelf and unit code numbers to identify the item color. Note
that there is no functional difference between gray and black versions of
individual module types sharing the same code numbers as there is no
difference in their internal electronics/hardware. Note that the gray colored
modules were discontinued in June 2008. The modules added to the product
portfolio after November 2007 have been available in black only.
