AAAL AAL1 AAL2 AAL3 - 4 AAL5 ABC ABR ABS ACD ACELP ADPCM ADSL ADTF AFI AIS AM API A_PCR APPN APS AQM ARN ARP ASIC ATM ATMARP ATMIF ATM MPE ATUATM Adaptation Layer .The AAL is what gives ATM the flexibility to carry entirely different types of services within the same format. It is important to understand that the AAL is not a network process but instead is performed by the network terminating equipment. Thus the networks task is only to route the cell from one point to another, depending on its header information. Transport for constant bit rate data traffic as voice, video or other continous user data . Contains timing information, CRC for error detection and corection for AAL overhead. Variable bit rate as video or other interrupted user data. Uses MINI CELS that have 3 octets header and payloads up to 64 bytes Merge of AAL3 & AAL4. Variable lenght frames and packets. Inefficient, is replaced by AAL5 ATM adaptation layer 5 -1 VCC per trunk. Passport trunks over ATM carry DPRS traffic using AAL5 to convert frames to ATM cells. ATM buss controller avaible bit rate* ABR is an ATM layer service category for which the limiting ATM layer transfer characteristics provided by the network may change subsequent to connection establishment. ATM bearer service An Automatic Call Distributor (ACD) is a telephone facility that manages incoming calls and handles them based on the number called and an associated database of handling instructions. Many companies offering sales and service support use ACDs to validate callers, make outgoing responses or calls, forward calls to the right party, allow callers to record messages, gather usage statistics, balance the use of phone lines, and provide other services.

Typically, a call center has the ability to handle a considerable volume of calls at the same time, to screen calls and forward them to someone qualified to handle them, and to log calls. Call centers are used by mail-order catalog organizations, telemarketing companies, computer product help desks, and any large organization that uses the telephone to sell or service products and services. Virtual call center is a call center in which the organization's representatives are geographically dispersed, rather than being situated at work stations in a building operated by the organization. Virtual call center employees may be situated in groups in a number of smaller centers, but most often they work from their own homes. This is an attractive arrangement for many employees: the hours are often flexible, and there's no dress code or commute. For the organization, the virtual call center model saves housing and equipment costs and can lead to lower employee turnover rates, which tend to be high for physical call centers. CallPilot 4.0 provides a variety of new unified messaging features, as well as Cost of Ownership improvements designed to help reduce on-going management and maintenance costs. CallPilot is a unified messaging application for businesses using Meridian 1 PBX phone systems, Meridian SL-100, Communication Server 1000, and CPE Centrex systems. It combines voicemail, e-mail and fax messages into a single mailbox accessible by phone, any desktop PC, or mobile e-mail enabled devices (PDAs). CallPilot Unified messaging provides a compelling solution for businesses that are looking at reducing costs, improving productivity, and staying connected to their customers and suppliers.

It requires BTDS for signaling- ts 24 for DS1, ts 16 for E1 CDMA (code-division multiple access) refers to any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands cell delay variation Cell delay variation tolerance also known as network jitter (tolerance) Code excited linear prediction circuit emulation service Contivity Extranet Switch Control and function processor congestion level Customer identifier Cost,Insurance and Freight(... named port of destination) means that the seller delivers when the goods pass the ship's rail in the port of shipment. The seller must pay the costs and freight necessary to bring the goods to the named port of destination .The CIF term requires the seller to clear the goods for export. This term can be used only for sea and inland waterway transport. If the parties do not intend to deliver the goods across the ship's rail, the CIP term should be used. Chief Information Officer (CIO) is a job title commonly given to the person in an enterprise responsible for the information technology and computer systems that support enterprise goals. Carriage and Insurance Paid To(... named place of destination) means that the seller delivers the goods to the carrier nominated by him but the seller must in addition pay the cost of carriage necessary to bring the goods to the named destination. This means that the buyer bears all risks and any additional costs occurring after the goods have been so delivered. However, in CIP the seller also has to procure insurance against the buyer's risk of loss of or damage to the goods during the carriage. Consequently, the seller contracts for insurance and pays the insurance premium.If subsequent carriers are used for the carriage to the agreed destination, the risk passes when the goods have been delivered to the first carrier. The CIP term requires the seller to clear the goods for export. This term may be used irrespective of the mode of transport including multimodal transport.

Community of interest COI COMPANION The name for the communication systems which use radio technology to transmit and receive WIRELESS signals between its components and the Business Communications Manager. A contact center (also referred to as a customer interaction center or e-contact center) is a central point in an enterprise from which all customer contacts are managed. The contact center typically includes one or more online call centers but may include other types of customer contact as well, including e-mail newsletters, postal mail catalogs, Web site inquiries and chats, and the collection of information from customers during in-store purchasing. A contact center is generally part of an enterprise's overall customer relationship management (CRM).A contact center would typically be provided with special software that would allow contact information to be routed to appropriate people, contacts to be tracked, and da
