ing power. All trunks and stations are assigned according to the default numbering plan.
This numbering plan is flexible and may be changed to suit customer requirements. The
installing technician customizes this default data to meet the end user’s requirements.
The system can be programmed from any LCD display keyset without interrupting system
operation. There are three levels of programming: technician, customer and station. The
technician level has access to all programs and can allow the customer access to system
programs as needed. Technician and customer access are controlled by different security
passcodes and access procedures.
The DCS also allows the use of a proprietary computer program called PCMMC. This
permits a technician to program the system using a personal computer. PCMMC can be
used on-site to modify the customer database or to download (save) the entire customer
database to a file. This file can then be saved as a backup and be uploaded when required
to restore the database.
Through the use of modems, PCMMC can access a DCS system remotely (off-site) to
make database changes or perform uploads or downloads of the customer database as if
the technician were on-site.

CADENCE (CVM8A)
The CADENCE Voice Mail system is a fully integrated
Auto Attendant/Voice Mail/Fax System on a single DCS
circuit card (see Figure 2–7). This optional card is desig-
nated the CVM8A and provides 4 or 8 channels of com-
munication. Only one card is permitted per system and
it can be installed in any universal card slot.
This fully featured self contained system is connected
directly to the DCS data bus and communicates with the
DCS processor. This design means that installation time
is minimized, operation is streamlined and many fea-
tures can be implemented that are not normally possible
with older conventional stand alone Voice Mail/Auto At-
tendant systems.
All power to run this self contained system comes from
the DCS telephone system power supply. Each of the
DCS power supply is rated according to the number of stations it will support. When
CADENCE is installed it counts as (8) eight stations of the PSU 40 or PSU 60 rating
regardless of the number of Voice Processing Modules installed.
NOTE: Requires DCS Release 4.x or higher software.
