Calls will be launched by dialinga commercial toll-free number for authorization prior to reaching the on-netterminating location. The 10-digit authorization code plus a 4-digit PIN numberprovides a means for overriding the default level of screening associated with acaller’s telephone line. This temporary override of COS restriction assigned to acaller’s station allows an individual user to place an on-net call at a higher networkCOS for the call’s duration. AT&T will support actual requirements for calling partyidentification, COS assignment, specified by the Government as part of serviceordering. The authorization code feature is described in paragraph 2.2.1.2.2.1.b.4.When the COS is overridden by an authorization code, the call will be billed to theholder of the authorization code. Call processing will be without excessive delaycaused by waiting for digits to be dialed before recognizing the call as one involvingan override. Critical users with priority access to FTS-LD services will be providedauthorization codes unique from all other users.Upon successful matching of the authorization code to a caller group list, the networkwill determine from the screening group list currently in effect (dependent on timeand day) whether the call is permitted to proceed. If the call is not allowed, the callwill be routed to an appropriate announcement. If the call is permitted to proceed, thenetwork will instruct the AT&T switch to process the call. CDRs for the call willreflect the authorization code entry to redirect billing the call to the holder of thecode, rather than to the originating station.FTS-LD Calling Cards will be made of durable plastic with magnetic strip (swipe)coding and imprinted with authorization code, user’s name, and organization.

FTS-LD will support stationidentification via CCITT No. 7 signaling from the access providers whereit is available. In addition, the network will support ANI from PBXs usingcentralized automatic message accounting signaling. This will coveroriginating station identification from Integrated Services Digital Network(ISDN) terminal equipment.2. Time and Day Restrictions ⎯ The screening group list to which the callergroup lists points may vary by time of the day, day of the week, and day ofthe year to provide flexibility requested in the RFP. There may be___________ specified for the caller groups.3. Traveling Classmark ⎯ This feature will provide for the acceptance oftraveling classmarks from any FTS-LD location served by PBXs andCentrexes that are able to provide these classmarks, including calls extendedby operators. For FTS-LD, traveling classmarks generated by PBXs orCentrexes will be accepted for call screening privilege determination. Callscreening will then proceed as described earlier in this section. The acceptableformat will conform to the Travel Class of Service (TCOS) format.The user PBX or Centrex will need to be configured for operationscompatible with transmitting a traveling classmark. This will usually be asoftware translation in the PBX. No additional special interfaces (e.g., FeatureGroup D) are required. There is no limitation to the implementation of thisfeature caused by the type of representative equipment at the SDP, except forthe requirement that the equipment must in fact generate a traveling classmarkin the specified format.Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposal.q:\mcghee\vol_1sec2d_r.docI-2-89

The entire platform is designed, developed and supported by a team ofAT&T personnel that are dedicated to supporting only AT&T TeleConferenceServices. At the core of the architecture is a proprietary; custom-developed OperatingSupport System (OSS). This OSS is comprised of leading edge hardware supplied byand in partnership with the best in the industry, including manufacturers such as SUNand IBM. The hardware platform is a complex, three-tiered architecture deployed atmultiple sites around the world. The data network is the same data networksupporting AT&T’s most mission-critical applications, including its core 4ESS voicebackbone network. The software running the OSS is primarily custom-developed, butalso makes use of state of the art operating systems, database systems and othersoftware components. Some of the software partners include Sybase, Oracle and Sun.In addition to this core OSS, AT&T TeleConference Services utilizes and integrateswith several other components, including AT&T’s voice and data network, CustomerCare call centers and bridges. AT&T TeleConference Services utilizes sophisticatedteleconference bridges of various types, strategically placed throughout the AT&Tnetwork, to reduce the impact of any network failure. The primary bridge type used isa custom-developed, proprietary bridge that was designed by and supported byAT&T TeleConference Services Development Team in conjunction with AT&TLabs.

Each of the various hardware, software, and networkcomponents associated with our bridging technology has its own back up andrecovery plan. AT&T’s standard practice is to appropriately staff trainedmaintenance personnel twenty-four hours a day, seven days a week.The audio teleconference network supports High Availability Software, which inessence is a redundant configuration. This redundancy allows constant monitoring;therefore, if one component is not functional, the other component will support thefunction.Our audio teleconference network is designed with spare and backup equipment thatcan be automatically or manually activated. In the unlikely event these backups fail,emergency plans allow us to re-route calls to one or more of the alternate bridge,operator or central office locations not impacted by a failure, via AT&T FastRestoration Service (FASTAR). The FASTAR network control mechanism allowsAT&T network traffic to avoid outages and/or reroute traffic in the event of outages___________.AT&T employs an uninterruptible power supply system at central office facilities.Should commercial power fail, AT&T Conference Offices are equipped with UtilityPower Supply (UPS), battery backup, and generators. The switching and bridgingequipment is powered directly with DC power through a series of lead acid batteries.These batteries can survive for ___________ without being recharged.
