Issue 1, May 1986 
2.01 Introduction. This section describes the design con- 
siderations and maintenance facilities incorporated in the 
SATURN IIE EPABX. The maintenance concept for the EPABX 
is based on detecting and isolating failures to the Least 
Replaceable Unit (LRU), replacing the faulty LRU, and restor- 
ing normal service as soon as possible. The maintenance con- 
cept does...

2.03 Design Considerations. The design considerations in- 
corporated in the SATURN IIE EPABX are discussed below. 
a. Component Packaging. The SATURN IIE EPABX ar- 
chitecture is modularly designed to allow maintenance 
personnel to quickly recognize and isolate failures. 
Modularity is achieved primarily by using Large Scale 
Integration (LSI) and Medium Scale Integration (MSI) 
techniques. Extensive use of...

either a portable test phone, test set, or a standard two-wire 
station instrument used to access the maintenance functions 
of the system, either locally or remotely. 
a. Local Maintenance Functions. The maintenance line 
is usually assigned as a Dual-Tone Multifrequency 
(DTMF) station type; however, a Dial Pulse (DP) or 
DTMF maintenance phone may be...
