1. Product Description

ISAP300 is a 3U photoelectric integrated service access SDH transmission equipment, with the company's own development of integrated circuit design, transmission multiplexing unit using SDH/MSTP technology, with two stm-1 / stm-4 line optical interfaces, fusion into the optical transmission network through the standard SDH interfaces, to realize the network architecture of access and transmission integration. The device can be used for simple point-to-point long distance connection of optical fiber, or to form self-healing ring network or chain network, or to realize complex cross-network interconnection with SDH transmission network. The ISAP300 provides 10 slots, including two power slots, two main control upper slots, one fan slot, and five service slots. All service slots, except for the Ethernet sink card, support the mixing of various service function cards for flexibility and convenience. Business categories include E1, Ethernet, FXS, FXO, audio 2/4 line, EM signaling, magnet telephone, hotline, synthetic 64K interface, RS232, RS485, etc.
