Composite switching array and branching apparatus testing method therewith

Abstract

The method includes following steps: the complex switch array consists of several single pole single throw switch group comprising three single pole single throw switch, the reception end switch, the transmit end switch, the cascade switch; in the single pole single throw switch group, one end of each reception end switch in single pole single throw switch group is made short circuit together, the another end is connected with the transmit end of corresponding branch circuit; one end of each transmit end switch is made short circuit together, the another end is connected with the transmit end of corresponding branch circuit; each cascade switch is connected with the transmit end reception end of two neighbor branch circuit.

Description

technical field

[0001] The invention relates to digital communication equipment testing technology, in particular to a method for testing branch equipment using a composite switch array, and the composite switch array. Background technique

[0002] In the information society, people want to be able to obtain the required information at any time, any place, and in any convenient way. The continuous growth of this business demand directly leads to the unlimited demand for communication capacity and bandwidth. Large-capacity optical communication transmission systems The equipment has become the mainstream equipment in the construction of backbone networks, metropolitan area networks and access networks in various places.

[0003] With the maturity of digital synchronous transmission equipment product design technology, for a single independent branch device, its port capacity is getting larger and larger, from the early 4-way, 8-way to the current 32-way, 63-way, etc. For its...
