Network Management Overview

An internal data bus, also called a controller area netwo rk (C AN) bu s, co nnec ts a n N C B modu le to

different CLIP modules of the ONS 15252 MCU. You can extend this data bus over several co-located

network elements (ONS 15252 MCUs or ONS 15201 SCUs) to a larger logical unit. The ONS 15201

SCU uses the same data bus as the MCU. Normally one CAN bus c onn ect s al l ON S 15 200 e quip ment

located at one site.

An overhead channel exists and is implemented as a base b and m odu lat ion on the ind ivi dual DW DM

optical channels. Two end-points of a channel communicate using this low frequency sign al, called QPP

(Qeyton Proprietary Protocol). The QPP specification defines the physi cal an d lin k laye r pro toco ls f or

communication.

Any CLIP module controlled by an NCB must not be more than two QPP hops awa y f rom that NCB. If

the CLIP is further away from the NCB, you must install additional NCB modules.

Release 1.1 allows you to configure up to two active NCBs as managers of any CLIP in a network. To

manage the CLIP, it must be no further than two CAN and two QPP hops away from the NCB. Any NCB

in a network that is not provisioned as an active manager of a CLIP can still inventory the CLIP.
