For basic rate access in an Integrated Services Digital Network (ISDN) environment, a user-to-network interface reference point that (a) is characterized by a 4-wire, 144-kb/s (2B+D) user rate, (b) serves as a universal interface between ISDN terminals or terminal adapters and the network channel termination, (c) allows a variety of terminal types and subscriber networks, such as PBXs, local area networks (LANs), and controllers, to be connected to the network, and (d) operates at 4000 48-bit frames per second, i.e., 192 kb/s, with a user portion of 36 bits per frame, i.e., 144 kb/s.

All > Technology > Security
A set of specifications for securing electronic mail. Secure/ Multipurpose Internet Mail Extensions (S/MIME) is based upon the widely used MIME standard and describes a protocol for adding cryptographic security services through MIME encapsulation of digitally signed and encrypted objects. The basic security services offered by S/MIME are authentication, non-repudiation of origin, message integrity, and message privacy. Optional security services include signed receipts, security labels, secure mailing lists, and an extended method of identifying the signers certificate(s).

Amazon Simple Storage Service (S3) is the distributed storage component of the AWS platform. It can read, write, and delete objects representing data ranging from 1 byte to 5 gigabytes. You can use S3 to store, replicate, and persist an unlimited amount of objects in the cloud. However, you should not think of S3 as a local disk and attempt to run your database from S3. S3 simply stores "objects" or files, in "buckets" (folders). Since there are no directories in S3, each bucket is given a unique identifier. You can also have multiple buckets under one account. Many customers serve static files such as images or video directly from S3 instead of having them stored on a local disk. This gives them virtually infinite storage capacity for their files without purchasing any hardware. For more information visit: http://aws.amazon.com/s3.
