Remote module control system for controlling module disposed at remote place which accommodates line/trunk circuit and control method thereof

A remote module control method of controlling, from a switching system, a remote module which is disposed at a place remote from said switching system and accommodates a plurality of line/trunk circuits, comprising the steps of:

• in said remote module,
• managing data information indicative of existence/non-existence of data to be transferred which is to be transferred to said switching system and notifying said switching system of the data information as required, and
• transmitting said data to be transferred indicated by said data information to said switching system, and
• in said switching system,
• storing said data information and said data to be transferred received from said remote module at predetermined storage means,
• setting reception information indicative of the reception of said data to be transferred based on said data information stored at said storage means, and
• obtaining said data to be transferred stored at said storage means according to said reception information by a central processor mounted on said switching system for controlling said line/trunk circuits, and
• wherein
• said data information management step of said remote module includes:
• setting first flag data indicative of existence/non-existence of said data to be transferred, and
• monitoring said first flag data to transmit said first flag data to said switching system according to the state of the first flag data.

A computer readable memory storing a remote module control program for controlling, from a switching system, a remote module which is disposed at a place remote from said switching system and accommodates a plurality of line/trunk circuits, said remote module control program comprising the steps of:

• in said remote module,
• managing data information indicative of existence/non-existence of data to be transferred which is to be transferred to said switching system and notifying said switching system of the data information as required, and
• transmitting said data to be transferred indicated by said data information to said switching system, and
• in said switching system,
• storing said data information and said data to be transferred received from said remote module at predetermined storage means,
• setting reception information indicative of the reception of said data to be transferred based on said data information stored at said storage means, and
• obtaining said data to be transferred stored at said storage means according to said reception information by a central processor mounted on said switching system for controlling said line/trunk circuits, and
• wherein said data information management step of said control program at said remote module includes:
• setting first flag data indicative of existence/non-existence of said data to be transferred, and
• monitoring said first flag data to transmit said first flag data to said switching system according to the state of the first flag data.
