Multilocation Business Group (MBG) technology provides connecting locations-and source revenue local carriers
Multilocation Business Group (MBG) services designed meet needs organizations served multiple switches same LATA, such banks, real estate firms, health-care systems, school systems, government agencies. allows Meridian Digital Centrex (MDC) private-network traffic placed public CCS7 facilities while retaining customer-group identity. When call routed over public CCS7, identity customer group sent destination switch. This allows switch identify calls among members same customer group handle them differently than other calls.

Traffic routed over conventional public facilities loses customer-group identity because normal public trunks support customer-group information. Until MBG, only option retaining private identity calls private trunks among central offices PBXs. allows customer-group identification other information-such Meridian Switched Network (MSN) class-of-service (NCOS) traveling class mark (TCM)-to inserted CCS7 ISUP message sent other switches.

EVOLUTION MULTILOCATION BUSINESS GROUPS
Meridian Digital Centrex (MDC) initially nodal service, designed serve stations single switch. However, telecommunications needs evolved, Northern Telecom developed technologies allow interworking among customer groups different switches. includes features that enable subscriber dedicated private networks effectively, such automatic route selection (ARS), direct access trunks, private dialing plans, network class service (NCOS) control access various trunk routes. Meridian Switched Network (MSN)-also known Electronic Switched Network (ESN)- provides capabilities larger, more extensive private networks, used conjunction with other network services. Customer networks have traditionally used private dedicated trunks between switches (PBXs central offices). Each trunk group restricted traffic from customer group, traffic from particular customer group always placed trunks assigned that customer. This allows switch distinguish between private public calls determine customer-group identity call.

DMS-100 network services work with wide variety trunk types used connect central offices and/or PBXs private networks-both digital trunks older analog trunks. These trunk types in-band signalling carry limited amount call progress information between different switches. ISDN Primary Rate Access (PRI) Common Channel Signaling System Number (CCS7) separate signaling channel (out band signaling) which enable them send more information about call between switches. Area-Wide Centrex (AWC) represented considerable advance over trunk networks with in-band signaling because exploits advantages CCS7 signaling deliver true network features that operate across switches just they single switch. features include: Network Name Number Display Call Redirection with Number Reason Display Network Ring Again Network Attendant Service, including Call Park/Camp with Recall, Busy Verification, Network Name Number Display Network Message Services also used implement networked Centrex service that provide services except Network Attendant Services. AWC-like MSN-requires that private traffic segregated private interoffice trunks dedicated single customer group. switches serving customer distinguish between intra-network traffic other types traffic-and determine customer group identity call-because traffic from particular customer group always placed identifiable trunks. Some customers find disadvantages this reliance private lines networking: Some satellite locations generate enough traffic cost-justify private interoffice lines. network survivability concern, additional separately routed private lines have purchased case other lines fail. fixed capacity private lines cannot dynamically accommodate increases traffic. overflow calls proceeding over public trunks cannot identified internal calls terminating switch. Non-DID stations served cannot accessed from public network without intervening attendant.

SOLUTION
next step evolution Network Centrex-Multilocation Business Groups-is designed address these shortcomings allow private traffic share same interoffice facilities public traffic. added capabilities deliver many advantages networking customers: Satellite locations brought into private network without private lines. survivability mechanisms already place public network (e.g., alternate routing) exceed those available private network. Trunk usage more efficient through dynamic accommodation traffic changes. Corporate traffic keeps customer-group identity over public facilities, allowing internal calls identified, routed, billed such. intragroup feature privileges operate transparently across MBG. Non-DID stations served included network. services-it transport technology that allows features operate over shared public CCS7 trunks instead dedicated CCS7 trunks. accomplishes this allowing customer group identifier inserted Initial Address Message (IAM) CCS7. terminating switch uses this identifier distinguish incoming private calls from public calls, identify customer group which call belongs.

Non-Networked Customers, including Current subscribers Smaller subscribers currently networked because traffic levels justify private lines, partially networked through common dialing plan. Private-Network Customers have more extensive network private lines Primary Rate Interface (PRI) trunks. These businesses extend network access smaller sites where traffic levels justify private lines additional enhanced routing option among existing network locations. these customers, improve call handling, unify corporate network, improve call accounting. first cost-effective networking option many customers cannot afford private-line network. matter level traffic generated each location, MBGs unify corporate network deliver service levels comparable better than private-line network: Networked features-Many feature transparent MBG. Centralized Station Message Detail Recording (SMDR)-In many cases, customer reduce number nodes which SMDR collected, often centralizing SMDR single node.
