摘要： In an IP packet communication apparatus, an operation and maintenance function capable of monitoring a transmission path is provided to a layer used to process a packet, which corresponds to an upper layer of an optical network. As one method for applying the operation and maintenance function to the packet layer, in the case of IP over PPP over WDM, an operation/maintenance frame is defined to a PPP frame so as to realize the operation/maintenance function of a PPP connection. In the case that a plurality of connections are multiplexed on the same transmission path, a maintenance frame is conducted in order to operate/manage these connections by being grouped, so that a fault occurring in the optical network is monitored. As another method for applying the operation and maintenance function to the packet layer, an operation/maintenance frame is defined to an IP packet so as to realize an operation and maintenance function of an IP flow. Also, since a plurality of flows are multiplexed on the same transmission path, a management packet is defined to operate/manage these flows to be grouped, so that a fault occurring the in the optical network is monitored.

摘要： A terminal multiplexer is constructed in such a manner that it can be upgraded for adapting to a change in a transmission system. Line terminating equipment (LTE) having working high speed transmission lines and protection high speed transmission lines in 1:1, is constructed from such units as two sets of 10 G interfaces responsible for interface with the high speed transmission lines, and SELH which selects a high speed transmission line for which multiplex conversion is performed in relation to low speed transmission lines. When this LTE is to be upgraded to ADM adapted for 2-Fiber BLSR, the unit SELH is replaced with SWH which performs switching of signals in each time slot between a high speed transmission line and the low speed transmission lines. Upgrading during the system operation is possible by making signal interfaces with the outside common for SELH and SWH, and by making delay times between signal input and output coincide for various signals.
