This file is of course about DMS 100. Expect full length files about the other

variations of DMS (DMS 200 & 250) coming a later date. Much of the information

in this file was obtained from manuals acquired from Jester Sluggo.  Note: IBN

stands for Integrated Business Network.

DMS-100

-------

The DMS-100/IBN consists of electronic business sets and standard telephones,

data units, and attendant consoles, all located on the customer's premises; and

DMS-100 digital switching, and support hardware/software, located at the

telephone company's premises.  Together they create an integrated business

communications network that provides an unparalleled combination of features

and benefits.



o  DMS-100/IBN integrates voice and data in a total business communications

   system.



o  Effectively serves all sizes of organizations, from small businesses using

   only a few lines, to the most complex network systems with up to 30,000

   lines.



o  The IBN system monitors and controls its own operations automatically;

   diagnoses problems; and in some cases, does its own repairs.



o  Fully modular, to meet present needs, and accommodate new features as they

   are needed.



o  Cost effective: Helps control communications costs through more efficient

   use of facilities; centralization of attendant service where needed; Call

   Dial Rerouting (CDR) to control and restrict long-distance calling; and

   network management.



o  Worry free operation-Northern Telecom's DMS-100 digital switches are backed

   up by highly trained telephone company personal.

----------------------------------------------------------- --------------------



Some of the other features that DMS 100 has include:



o  Automatic Route Selection - automatically routes long distance calls over

   the most economical route available.



o  Station Message Detail Recording - provides a detailed record of long

   distance charges, including the originating number, time, and duration,

   authorization code, etc.



o  Direct Inward System Access (DISA) - enables company personnel to use

   cost-saving company facilities for long distance calling, even from outside

   the company.
