The optical transmission device includes an N&#xd7;N optical switch, an optical packet receiver and an optical packet generation unit. The N&#xd7;N optical switch transmits data in which a plurality of optical signals each having a different wavelength is multiplexed.

An optical communication apparatus includes a variable resistor unit, a measurement unit, and a control unit. The variable resistor unit is arranged at a pre-stage of an electrical/optical conversion unit, which converts an electrical signal obtained by converting an input packet to an optical signal having a waveform corresponding to a potential difference between a positive phase component and a negative phase component of the electrical signal by using the potential difference. The variable resistor unit provides a resistor that varies a midpoint of potential of the positive phase component or the negative phase component. The measurement unit measures a ratio of a presence period, which is a period where the input packet is present, to a sum of the presence period and a non-presence period. The control unit controls a value of the resistor provided to the positive phase component or the negative phase component based on the ratio.

An optical packet switching device causes branching of an optical packet that is input to an optical switch and detects a synchronization pattern having a predetermined number of bits from the branched optical packet. Then, the optical packet switching device calculates a synchronization point indicating a location of the synchronization pattern with respect to a detection timing and controls, in accordance with the calculated synchronization point, a delay amount of a delay element that delays an optical packet ON signal that is output to the optical switch.

In the present invention, a portion of the outer surface of a wrapper of film unit with lens is previously constructed in a manner capable of being peeled therefrom. When the portion of the surface is removed, such as a photographic objective and a finder of the film unit with lens are exposed. Thus, photographing is possible in the state where the film unit with lens is covered with the wrapper, thereby the wrapping is efficiently used. In the present invention, peeling portion capable of being peeled may also be provided continuously through the front surface, the upper surface and the rear surface of the wrapper. When such peeling portion is peeled, the front surface of the peeling portion may be bent from the wrapper at a folding line, whereby a projecting piece may be inserted into between the peeling surface and a plane at the rear surface thereof. Thus, the peeling portion is not separated at the time of photographing and, after photographing, it may be easily pasted to its original state to be used as a protection cover thereof if an unexposed film still remains.

A digital subscriber line formed by terminal equipment, a network control device including a plurality of the terminal equipment, and an exchange terminal. In a waiting state of the digital subscriber line, the network control device is placed in a state which can only receive a signal. A sending portion of the network control device is driven when, at a call from the terminal equipment, the terminal control device receives a line activation signal from the exchange equipment and when, at an incoming state from the state from the exchange terminal, the terminal control device receives a line activation from the exchange equipment. The synchronization pattern signal is sent from the sending portion to the exchange terminal so that the synchronization of the exchange terminal is established.

System for controlling network activation sequence

A digital network system having an arrangement for testing a digital subscriber line includes a switching device, an exchange terminal device as a subscriber circuit connected with the switching device, a subscriber line connected with the exchange terminal device, a network terminal device at a subscriber's side connected between the subscriber line and terminal equipment devices. The network terminal device includes a turn-around portion for forming a turn-around loop through which the turning-around of a signal to the subscriber line connected with the network termination device is carried out, and a discrimination portion for detecting that data transmission can be carried out and cancelling the formation of the turn-around loop. The turn-around loop is formed when a frame synchronization bit signal from the exchange terminal device is received by the network terminal device and cancelled when the discrimination portion detects that data transmission can be carried out. Communication for either a monitoring of transmission or a bit error testing can be carried out between the network terminal device and the switching device while the turn-around loop is formed, and data transmission between the exchange terminal device and the terminal equipment devices can be carried out after the turn-around loop is cancelled.
