The DMS-200 Auxiliary Operator Services System (AOSS) is used primarily for
Directory Assistance and the intercept needs that are not included in the TOPS
package. The AOSS is similar to TOPS and co-exists with TOPS on the DMS-200
Toll system.
Major benefits of the AOSS include: Directory Assistance is provided with a
modern environment, AOSS position administrative activities are performed by
the DMS-200 toll maintenance system, trunking savings are achieved by
combining trunking for 1+, 0+, and Directory Assistance traffic, DA services
are managed by using TOPS methods, creation of a built-in training system
which does not require additional training equipment and reduces training
costs.
Integrated Business Network
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Integrated Business Network (IBN) is a revenue-producing concept designed
for small and big businesses to offer modernized PBX and Centrex features.
The Operating Company can use the IBN to maintain and enhance its competitive
position on a operational DMS-100 and DMS 100/200 switches. While using the
DMS-100 switch, the Operating Company can support varying business features
along with existing local/toll traffic.
IBN services can be introduced to a Centrex-Central Office (CO) or a
Centrex-Customer Unit (CU) by additional software modules and minor hardware
enhancements.
Current IBN features include: A growing system that can handle 30,000 lines,
networking capabilities, city wide service for DMS-100 switch and remotes for
any one customer Station Message Detail Recording (SMDR), which gives IBN
customers call records. The records can be used for system analysis and
control and station charge-back. SMDR can use LAMA records (if the IBN host
has LAMA equipment), centralized attendant maintenance, and administration
functions and Direct Inward Dialing (DID).
Electronic Switched Network (ESN)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Electronic Switched Network is designed to meet the telecommunication
needs of large multi-location corporations. The ESN is made up of a SL-1 or
SL-100 Digital Business Communications System with networking features or a
DMS-100 IBN host. The SL-1 can handle from 30-5000 lines. The SL-100 and the
DMS-100 IBN hosts can hold from a few thousands to 30,000 lines.
A DMS-100 IBN or SL-100 can remotely serve many locations from the host site.
This is done by a connection through digital transmission facilities which are
set up at remote modules at the subscriber's premises.
Here are some diagrams showing the differences between normal private
telecommunications networks and ESN networks.
