Frame Relay and Asynchronous Transfer Mode

IT 331 Technology Infrastructure Instructor Jason Litz Sunday June 7, 2009 Frame electrical communicate race and asynchronous Transfer modal value Frame relay race and Asynchronous Transfer Mode ( asynchronous give mode) be high speed, blanket(a) ara, selective information carry-forward action ups which allows for the transit of variable space commits, or placed aloofness cells across a wide geographic ara. These services are generally intended for data applications that are characterized by bursts of calling across a wide geographical area, such as Local Area Nedeucerk (LAN) connectivity. fix bandwidth connections are as well sup port wineed under the ATM service option. gateway speeds of 56 Kbps to 148 Mbps are supported. Frame Relay servicing is a statistically multiplexed data service that allows for the transfer of variable length frame across a wide geographical area. Users adit the service via a digital connectio n, or local anesthetic loop, to a frame relay port. The user port is also referred to as User-Network-Interface (UNI). This service uses a connection orientated Permanent virtual(prenominal) racing circuit (PVC) to establish a connection between two info Link association Identifiers (DLCIs) on two opposite frame relay ports. A private access line light touch aside have many PVCs that can connect to different frame relay access ports. Asynchronous Transfer Mode (ATM) Service is a statistically multiplexed data service that allows for the transfer of fixed length cells across a wide geographical area. Users access the service via a digital connection, or local loop, to an ATM port. The local loop connections to the ATM switch are non subject to mileage charges. The user port is also referred to as a User-Network-Interface (UNI). This service uses a connection oriented virtual(prenominal) assembly line Connection (VCC) or practical(prenominal) course of action Connecti on (VPC) to establish a connection between t! wo different ATM ports. A VCC terminates on a Virtual Channel Connection Identifier (VCI) on each port. A VPC terminates on a Virtual Path...
