Title:
NETWORK NODE INTERFACE OF DIGITAL COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JPH03173243
Kind Code:
A
Abstract:
PURPOSE: To switch a time slot in a time division multiplexed process for a terminal of an individual subscriber in an optionally desired arrangement and order between the terminal of the subscriber and a switching center by providing buffer memory having partial memory. CONSTITUTION: Digital switching centers VS1, VS2, etc., are connected to this network node interface 300, and each subscriber terminal 313 is connected to the interface 300 via a distributive connecting part 311, an optical waveguide body 319, a front end device 324 and an optical waveguide body 318. A time division multiplexed signal that is supplied to terminals 1 to 144 of a 1st interface A of the interface 300 and a time division multiplexed access signal supplied to terminals 1 to 24 of a 2nd interface B are separately switched and outputted to other terminals. That is, a time slot in a time division multiplexed process for an individual subscriber terminal is switched and outputted in an arbitrarily desired arrangement and order between the terminal 313 and VS1, VS2 via a memory 303, etc., which has partial memory.
