SYSTEM MAINTENANCE ALARMS
The 400si continuosly performs internal system diagnostics. When either a major
or minor fault is detected the system can ring stations with an ALARM KEY as-
signed. The keyset display shows information that includes the description, loca-
tion and date and time stamp for each alarm.
A log of 100 alarms are stored in a buffer and can be reviewed at a display keyset
or sent to a printer (see sample Alarm Report in section 4.11 of this document). In
addition to the keyset displays LEDs, the front of the DCCU card will light to indi-
cate a major or minor alarm.
SYSTEM DIRECTORY
Each station, station group and outside line can have an 11 character directory
name. This name will appear on keyset displays to provide additional information
about lines and stations.
TENANT SERVICE (2)
There are several programs that allow the DCS 400si to be installed in tenant
applications. These features allow a technician to split the system in two with each
tenant having individual control over operator groups, page zones, ring modes
(manual or automatic), DISA and customer level programming. Each tenant is sepa-
rate. No intercom calling between tenants is permitted.
TOLL RESTRICTION
There are 500 allow and 500 deny entries of 11 digits each. Each of these entries
can apply to dialing classes B, C, D, E, F and G. Expensive 976, 1-900, 411 and
operator-assisted calls, as well as specific area and office codes, can be allowed or
denied on a per-class basis. Class A stations have no dialing restrictions and Class
H stations cannot make outside calls.
Any outside line may be programmed to follow station toll restriction or follow the
toll restriction class assigned to it. Each station and trunk can have a day dialing
class and a night dialing class.
SPECIAL CODE TABLE
A Special Code Table of ten entries (four digits each) allows use of telephone
company features such as CID blocking (✱67) or call waiting disable (✱70) without
interference to toll restriction or LCR. The Special Code table allows use of these
custom calling features on a per call basis.
TOLL RESTRICTION OVERRIDE
Program options allow system speed dial numbers to follow or bypass a station’s
toll restriction class. In addition, users may make calls from a toll restricted station
by using the walking class of service or authorization code feature.
