摘要： An interface device is provided which may be used to perform rate adaptation and time slot assignment, in either the transmit or receive directions, in a multiplexing unit for interfacing a high rate optical carrier line to a plurality of lower rate information carrier lines. The high rate optical carrier line may be a SONET or SDH carrier line. The interface device according to the present invention may be operationally configured to provide data rate adaptation and time slot assignment between an optical carrier line operating at an OC-12 rate with lower rate lines operating according to OC-3, OC-1, DS-3, or DS-1 protocols, or even virtual channels. A plurality of identical interface devices may be cascaded together and used to perform interface support for various channels operating at various rates, merely by manipulating the operational configuration of the individual interface devices in the cascade.

摘要： A universal tributary interface group approach for SONET multiplex equipment in which the shelf is partitioned into regions and each region can be provisioned to support different service types. The universal tributary group system includes an equipment shelf having a backplane. The equipment shelf is partitioned into regions called tributary groups which are each capable of accepting tributary units having compatible bus widths and clock rates. Removable card guides may be inserted into the tributary group spaces so that tributary interface units of different heights and widths may be placed in the tributary group spaces. Additionally, a plurality of bus segments run along the backplane to electrically connect a time slot interchange unit to card slots in the tributary groups. Each of the bus segments is capable of being provisioned to use a bus rate compatible with the data requirements of the tributary group it services.

摘要： In a telephone system having multiple working metallic interface units, a method and a structure provide protection by assigning to each metallic interface unit a partner unit, which is another metallic interface unit. Under this arrangement, when a failure occurs in a working metallic interface unit, its partner unit switches the ring/tip input signals of the failed metallic interface unit to a protection bus. A standby or protective unit then takes over by receiving the rerouted tip/ring signals from the protection bus. The failed working unit can then be removed from the shelf without disrupting service.

摘要： A circuit having a completely synchronous and digital implementation for encoding a stream of digital data (NRZ form) into the coded marked inversion (CMI) format. The circuit includes a state machine having a predetermined number of defined legal and illegal states, an illegal state detection circuit, and an output circuit. When the state machine enters an illegal state because of, for example, the effects of noise or distortion on the digital data signal, the illegal state detection circuit forces the state machine back into a legal state.

摘要： A Violating All Zero Octet (VAZO) detector for a ZBTSI clear channel data transmission system is described, which is optimized for minimum logic gate count, minimum circuit complexity, minimum external control signals and minimum signal processing delay, in a VLSI hardware embodiment which is advantageously implemented in application specific integrated circuit (ASIC) technology. An array of logic NOR gates scans input data for zero strings of data that could combine with an all-zero octet to violate the zero string criterion enables a zero string search to be performed with a minimum of circuit complexity. The use of an input shift register to buffer input data for other portions of the associated ZBTSI encoder provides for a minimized number of gates in a VLSI implementation.

摘要： A mechanism for 1:1, 1+1, and UPSR path-switched protection switching, particularly for optical interface units in synchronous optical network (SONET) multiplexer equipment. A working unit and a standby unit pair protect each other in the event of a failure of the working unit or the failure of the span connected to the working unit if both the working and standby units are connected to different spans. Each unit is made responsible for detecting failures of the span that it receives and is primarily responsible for detecting a fault within the unit's own hardware or software. When a unit or span failure is detected, switch control is localized to the two units (i.e. the working and standby unit) which eliminates the need for a third control unit, which reduces processing time and reduces the system hardware. Moreover, this feature allows distributed control of the system protection so that protection switching on multiple unit pairs can be performed in parallel rather than in a serial manner by a common control unit. Both unit and span failures are handled through the same signal pair and simple hardware.

摘要： A Coded Marked Inversion (CMI) encoding circuit having a completely synchronous and digital implementation for encoding a stream of digital data in non-return-to-zero (NRZ) format into the CMI format. The encoding circuit includes a clock for providing a clock signal having a certain period, an input circuit for obtaining two samples of the NRZ data during each clock period, and a state machine which, in response to the two samples of the NRZ data, produces CMI encoded data. In a more advanced implementation, the encoding circuit includes error encoding circuitry for detecting errors in the incoming samples of NRZ data. The encoding circuit then outputs data indicative of the rate at which errors are received.
