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. |
