EPLOYMENT
All generations of HiGain HLU and HRU modules are compatible with each other. Although all HiGain doublers
are backward-compatible with all prior HLU and HRU models, some of the circuit application enhancements of
newer doubler models require that all circuit modules be of the same vintage in order to realize these
enhancements. Enhanced doubler applications preclude the mixing of newer doubler models with older models of
the HRU and HLU.
provides a matrix of HiGain doubler deployment rules to achieve maximum circuit
enhancement. It lists:
•
Maximum number of doublers allowed for a given circuit, depending upon the doubler and line unit models
used to implement the circuit.
•
Any restrictions on the HRU models.
The Charles Ind. 343-00 and 340-00 shelves do not support the HLU-319 List 5A System Alarm
output on pin H. Also, if slots 1 and 2 of these shelves were wired for the 3408 Fault Locate unit,
they must be rewired to accept the HLU-319.
All spans are fully CSA-compliant unless otherwise specified. Circuits that use more than one
type of doubler are governed by the most limiting doubler rules. For example, if the HDU-451 is
used with the HDU-409, use the HDU-451 deployment rules.
