A system and method for integrating heterogeneous phone message mailboxes in a common interface. A message record is created in a data structure of a local telephone device when a phone message received over a first telephone line is stored in a local answering device is completed. A message alert is received when a remote phone message is stored in a remote mailbox associated with a second telephone line linked to the local telephone device. The remote phone message is sent to the local telephone device for silent playback. The remote message is marked as old at the remote mailbox. A message record is created in the data structure corresponding to the remote message. A program operates to produce an ordered message record list in the data structure that includes, for example, an interleaved chronological list of all phone messages stored in the local and remote mailboxes.

The invention discloses a multimedia rural scientific and technological information on-demand system, which includes a server, an on-demand device, a modulator, a cable TV network and a TV terminal, and is characterized in that: one or more servers are equipped with a broadband network interface or a telephone line The interface is connected with the telecommunication network or local area network respectively, and the computer with management and server functions is installed on the expansion slot of the computer. The on-demand card and the broadcast card are installed. The on-demand card is connected to the telephone line and one end of the demodulator respectively. The broadcast card is connected to one end of the modulator, and the other end of the demodulator and modulator is connected to the cable TV network cable. The TV at the user end is equipped with a receiving box connected to the cable TV network cable. The receiving box is equipped with a matching infrared remote control . The invention can not only realize telephone ordering, but also use infrared remote controller to perform ordering, and the ordering operation is simpler and more flexible; it is suitable for both analog TV and digital TV; the cost of management equipment is low; and remote maintenance and management of equipment can be realized.

The invention discloses a novel optical fiber composite low-voltage cable. The cable comprises a cable core, wherein the cable core is formed by concentrically twisting multiple low-voltage power cable insulated cores and an optical cable; a covering tape layer, an armor layer and an outer sheath sequentially and concentrically wind around the cable core. Power cables and the communication optical cable are integrated in one cable, the purpose that the entering problem of cables is solved once through one-time construction and one passage only is achieved technically, repeated construction of multiple lines such as electric wires, network cables, telephone wires, cable television cables and the like in the past can be replaced, and cable resources and pipeline resources are greatly saved. The cable integrates functions of optical fiber communication and power transmission, has the characteristics of high-reliability data transmission, low price, convenience in connection and the like, has the advantages of small outer diameter, low weight and small occupied space, and is important to future data transmission for home intelligentization, office automation, digital substations and industrial control networking.
