Inventor: ROSMOVITS BERNARD A
IPC: H04L12/56
Filed: 1990-11-20
Abstract: A circuit is provided for forming fixed length blocks of information units received from one network for transfer to another. The actual information from each serially received information unit is stored in a receive buffer. A block header register is provided to store the logical channel number, block byte count, and a bit map having locations corresponding with each of the actual information units stored in the receive buffer. Once all of the information units have been received, the header register provides its output to the receive buffer for storage in a header location. The receive buffer thus forms a fixed length block which can be transferred to another network for processing.

Abstract: It has been discovered that tilted optical fiber endfaces useful in low-reflection optical fiber joints can be produced by cleaving, provided the fiber is twisted through an appropriate twist angle. By way of example, for a particular, commercially available single mode fiber, the normalized twist angle typically is in the range of 5-15 degrees/cm, resulting in a nominal tilt angle of the fiber endface in the approximate range 5-20 degrees. 
     Exemplary apparatus for the practice of the invention, comprises conventional cleaving means (30) and means (36) for imparting a twist to an end portion of fiber (31). The fiber is clamped in first holding means (32), and the end of the fiber is held in collet (37), which in turn is rotatably held in support means (38). After rotating the collet through an angel ϑ about the fiber axis by means that are not shown, second holding means (34) are used to clamp the fiber in position and optionally to apply an appropriate tensile force (typically in the range 50-300 gm, resulting in a tensile stress in 125 µm fiber in the range 4200-25000 gm/mm²) to the portion of the fiber between (32) and (34). Optional backing means (35) may be used to substantially prevent lateral motion of the fiber when cleaving tool (33) is brought into contact with the fiber. Optionally, the cleaving tool is ultrasonically driven and/or heated in known fashion, and the backing means comprise a semi-rigid contact material, e.g., silicone rubber. Other contact materials, both less rigid ones and more rigid ones, may also be used. For the relatively small twist angles of interest herein the twist angle at the cleavage point is (x₂ϑ)/x₁, wherein x₁ and x₂ are the indicated distances between holding means (32) and collet (37) and cleaving tool (33), respectively.

Abstract: An electronic messaging system allows a system subscriber to record a plurality of "customized" personal greetings which are played in response to incoming calls to the messaging system. Each of these greetings is placed in a message "pool" and a message system subscriber can specify the greeting that is to be played for each of a variety of call types. Each call type serves to differentiate between incoming communications based on one or more predetermined characteristics. Such call types, for example, may differentiate between incoming communications which are answered due to the called party not answering, or the called party being busy, or the call is received after normal working hours, or the call is an internal call, i.e., one that has originated on a local PBX or network of interconnected PBXs as compared to an "external" call which is of different origin. In addition, in a communications environment where an identification of the calling party is available, e.g., the telephone number of the communications device used by the calling party, each of a predetermined number of call types may be associated with one or more calling party identifications.
