MSAP multi-services access platform

Abstract

The patent relates to a MSAP multi-services access platform. The MSAP multi-services access platform comprises two master control disks, a webmaster disk, a backboard and multiple service disks, wherein each master control disk comprises more than one optical interfaces and multiple clock sources, each optical interface is used for providing an optical interface clock source for the master control disk, the optical interface clock source is accessed into another master control disk through the backboard; two master control disks are communicated with multiple service disks through the backboard; one of two master control disks is judged as the principle master control disk, and one clock source in the principle master control disk is selected according to the lock switching logic to output to two master control disks and multiple service disks. The selective output is performed among multiple clock sources through the clock switching logic, so that multiple clock sources on the principle master control disk are sufficiently utilized to facilitate the smooth access of the service and improve the platform reliability; furthermore, the services on two master control disks can be individually used or standby for each other, and the flexibility is good.

Description

technical field [0001] This patent relates to the field of data communication security, in particular to an MSAP multi-service access platform. Background technique [0002] Multi-Services Access Platform (Muti-Services Access Platform) adopts traditional SDH technology, based on SDH technology, adopts advanced GFP, VCAT and LCAS technology, integrates Ethernet switching technology and ATM switching technology, and realizes TDM business, Ethernet In addition, MSAP can also provide low-speed Nx64k dedicated line, Ethernet extension service (EoXDSL), etc. In MSAP equipment, in order to improve system reliability, the equipment regularly adopts the active and standby design of symmetrical structure. In general, the device timing can be provided by two uplink interface boards, each of which is active and standby. When there is a problem with the active clock, the system will switch to the standby clock in time to ensure normal business communication, but it can only realize the...

Problems solved by technology

In general, the device timing can be provided by two uplink interface boards, each of which is active and standby. When there is a problem with the active clock, the system will switch to the standby clock in time to ensure normal business communication, but it can only realize the communication between the two clocks. Switching is not conducive to accessing business information
