05.02 Functional block diagrams of the systems 
are shown in Figures 9 (STRATA XII) and 10 
(STRATA XX). The systems, which are nearly 
t f identical, consist of: station interfaces (MSTU), 
which include a portion of the solid-state switch- 
ing matrix; the MXPU PCBs, containing the re- 
mainder of the switching matrix; the CO line 
interfaces (MCOU); the intercom circuits (MINU); 
DSS interface (MDSU); power, paging and MOH 
- interface (MPRU); the central control consisting 
of the MCAU/AMMU (the AMMU...

MPRU - one per system: 
Performs several system functions: 
l Provides connection points for the 24 VDC 
input power. 
l Houses the voltage regulators that provide 
12 VDC and 5 VDC for system operation. 
l Houses circuitry and connection points 
for the relay services and music-on-hold 
(MOH). 
l Houses the external page amplifier.

EKT varies from the standard EKT only in dif- 
ferent dedicated key functions and lacking an 
intercom key (it is on the DSS). The DSS is e- 
quipped with up to 56 station keys, an intercom 
key, an All -Call page key, Message Waiting/Flash 
key and a Night Transfer key. Either system may 
be equipped with one or two fully functional 
DSS consoles. 
06.26 One or two DSS consoles may be option- 
ally added to either system as BLF consoles. Their 
only function is to provide station status 
information....

Automatic Callback (Intercom) : 
Permits a station user who encounters a busy 
station on intercom to request a callback by 
dialing a dedicated access code. The system then 
monitors the called station and signals the caller 
when it becomes idle. 
Automatic Dialing-System: 
This standard feature allows 24 numbers to be 
stored in the system memory. After selecting 
an outgoing line, any station user can cause 
one of the stored numbers to be...

may also be broadcast from EKT speakers 
and external page when the background music 
options are selected.
