Abstract

Synchronous equipment using the CCITT standard network node interface (NNI) is being developed. The equipment consists of three kinds of modules: a skip-level multiplexer which converts the existing switching and transmission system interfaces to the NNI, a TU-11 (24 CH) cross-connect device, and an STM-N skip-multiplexer with a line terminating function. These modules are implemented mainly with state-of-the-art CMOS VLSI and fiber-optic technologies. The equipment is expected to simplify the network, reduce its cost, and allow rapid provisioning. It is also expected to simplify and improve network maintenance and provide greater system versatility of services
