Toshiba Strata Vi Electronic Key Telephone System Installation And Maintenance Manual

DP for rotary dial outpulsing). 
Each !VICOU PCB serves up to 
three CO/PBX lines. 
MSTU-an interface between the 
MKSU and EKTs, which includes 
the solid-state space division mat- 
rix used for voice connections be- 
tween the EKTs and the CO/PBX 
lines. Each W!?TU PCB serves up 
to eight EKTs. Two-pair wiring is 
required for each EKT; one pair 
carrying voice and the other pair 
carrying data to and from the EKT. 
MCCU-all system control functions 
are performed by the single-chip 
microprocessor...

nor ma1 electrical power. 
No calls will 
be disconnected during switch-over to 
battery power. 
The principal components of 
the STRATA VI Electronic Key Tele- 
phone (Figure 8) are: Handset, Dial Pad, 
Speaker, Ringing

Speakerphone Volume Control, 2 Inter- 
com Keys, 6 CO/PBX Line Keys and 6 
Feature Keys, Keys for the Intercom, 
CO/PBX Lines, Speakerphone, Message

This section contains brief 
descriptions of the STRATA VI features 
listed earlier in Tables B and C and 
some associated operating instructions, 
Detailed operating instruct 
found in the STRATA VI 
or Operating Instructions. 
All Call Voice Page-dialing a one 
digit access code permits a station 
user to page via all EKT speakers 
simultaneously. The system can 
also be programmed to include the 
External Page feature in an All 
Call Page. 
Alternate Point Answer-an inter- 
com call can be answered...

The timing of 
the flash can be 
programmed to signal a PBX for 
feature operation or can be long 
enough to cause a disconnect and 
dial tone recall on a CO line. 
Also see Message Waiting. 
Flexible Line Ringing Assign- 
ment-a programmable ring or no 
ring option is provided for each 
line selectively by each station. 
Each line may be programmed to 
ring a maximum of eight stations. 
Message Waiting-the operator can 
indicate a message is waiting for 
any station with 
the Message 
Waiting/Flash LED...

Do Not Disturb-this feature is 
activated .and deactivated by al- 
ternate depressions of the DND 
key. A station calling a station 
that is in the DND mode will 
receive a fast busy tone. 
Executive Override of Privacy-a 
station that is programmed for this 
feature will override the automatic 
privacy feature and is able to 
enter any existing conversation. A 
warning tone, however, is inserted 
before the overriding station is 
actually connected. A maximum of 
two stations can be programmed 
for...

Night Transfer-the relay oper- 
ates (interrupted at the ringing 
rate) when the system is in the 
night mode and an incoming call 
appears. A “make” contact is 
provided to 
control a high 
power relay and loud ringing 
device. 
System Battery Back-up-an option- 
al PCB can be plugged into the 
STRA’T.4 VI EPSA to provide auto- matic switching to standby battery 
power. During normal power con- 
ditions the batteries are kept fully 
charged by the EPSA. 
20-key EXT-an optional executive 
unit provides,...

received, examine all packages and 
make careful 
note of 
any visible 
damage. 
If any damage is found, bring 
it to the attention of the delivery 
carrier and make the proper claims. 
Check the STRATA VI system 
against the purchase order and packing
