An add drop multiplexing (ADM) apparatus has a simple and compact structure. The ADM apparatus has high-order interfaces connected to a high-order network, path setting units each for setting a path for a signal according to path data and inserting or dropping the signal to or from the high-order network, a first path protection switch for selecting one of the signals dropped by the path setting units, low-order interfaces each for receiving the selected signal and transmitting the same to a low-order network, and a second path protection switch for receiving low-order signals from the low-order interfaces and transferring one of them to the path setting units so that the path setting units may insert the signal into the high-order network.
摘要:
An OEM processing device for supporting operations, administration, and maintenance (OAM) in an ATM network, whose control circuit has a simplified configuration that avoids duplexity of common functions, thus realizing reduced size and less power consumption. A VPI/VCI extractor extracts VPI/VCI from each incoming ATM cell, while an alarm detector detects a physical layer alarm. An entry data memory stores a plurality of VPIs/VCIs that have been previously registered. When the extracted VPI/VCI is found in the registered VPIs/VCIs in the entry data memory, a VPI/VCI coincidence signal will be generated. When a physical layer alarm is detected by the alarm detector, all the relevant VPIs related to the detected alarm will be generated by using the same entry data memory. A VP-AIS cell generator then produces VP-AIS cells corresponding to the generated VPIs and inserts them into the current ATM cell stream.

摘要:
In a jitter correction method and circuit, combination data combined by adding, to referenced data, an end bit of data 1 clock prior to and a head bit of data 1 clock subsequent to the referenced data is sequentially generated. Each bit of the combination data is sequentially referred. When a change between a referenced bit and a bit directly adjoining the referenced bit is detected, and when a number of references reaches a multiplication number of the oversampling and a change between at least three adjoining bits including the referenced bit is not detected, change position display data regarding the directly adjoining bit as a change bit of the referenced data is generated and the number of references is initialized. When the change is not detected and the number of references does not reach the multiplication number, the number of references is incremented. All the change bits are extracted from the referenced data and the change position display data, and a data reproduction is performed corresponding to the multiplication number.

Disclosed is a color image-formable material for forming and transferring a color image. The color image-formable material has a support, a cushion layer provided on the support and color light-sensitive layer containing a light-sensitive composition and a coloring agent provided on the cushion layer. It gives a transferred image by forming a color image portion by imagewise exposure and developing treatment and then transferring the color image portion alone to an image-receiving material. The cushion layer has a hardness of 40 to 85 and a thickness of 15 .mu.m to 100 .mu.m. A process for preparation of the color image-formable material is also disclosed.
摘要:
The setting and phase adjusting apparatus for synchronous multiplex communications is provided which adjusts phase differences of main signals caused between a plurality of synchronous multiplexing sections and a line setting section during line setting, in which to reduce the scale of circuitry of the line setting section in a transmission device for carrying out multiplexing and line setting on large-capacity signals, a plurality of pointer modifiers are arranged on a shelf on which the line setting section is arranged. The pointer modifiers connect the line setting section to the respective synchronous multiplexing sections. The pointer modifiers are supplied with multiplexed signals of respective signal series whose data head positions are shifted from one another. The head positions of these signals are synchronized with a timing signal from a timing generator by the pointer modifiers. Line switching is then effected by time switches and a space switch.

In a method and a circuit for timing pulse generation, a frame pulse of a corresponding system is masked when an alarm signal of either a working system or a protection system is received, a monitoring window which indicates an absorbable range of delay time difference between the frame pulses is generated upon an arrival of the frame pulse of the system selected by a switching signal, when the alarm signal of a system not selected is generated upon selection of the switching signal. Alternatively, a request signal for regenerating the monitoring window which indicates an absorbable range of delay time difference between the frame pulses is provided upon an arrival of the frame pulse of the system selected by the switching signal, when a slip signal is generated upon selection of the switching signal. The monitoring window is generated around the frame pulse selected by the switching signal when the monitoring window generation request signal is received, a read timing pulse common to memories of both systems is generated at a predetermined timing position, and the monitoring window is regenerated when the selected frame pulse deviates from the monitoring window. Alternatively, a correction signal including a number and a direction of bits when a reference timing pulse not selected deviates from the monitoring window is generated to be transmitted, the correction signal is extracted from a main signal received, and a position of the reference timing pulse of the protection system is corrected based on the correction signal, when the protection system is presently selected.

A transmitting apparatus for cross connecting and transmitting main signals which enter via ring-configured transmission lines to which working and protection channels have been assigned in first and second directions, and rescuing a main signal by looping back the main signal in the opposite direction using the protection channel when a transmission line fails. Storing non-rescue information which indicates whether each channel that is the object of rescue by loop-back is a non-rescue channel. Determining whether a failure for which rescue is impossible has occurred in each channel, which is the object of rescue, other than a non-rescue channel. On the basis of main-signal cross-connect information, interchanging a result of discrimination of each channel and inserting the interchanged result of discrimination in the main signal of the corresponding channel after cross connect.
