Frame classification

� The main control frame: manages and controls the whole UMG8900

equipment and provides clock signals for other frames.

� The central switching frame: implements frame subtending function.

� The service frame : implements service processing and interfacing

functions.

� The extended control frame: It is configured when the networking with

large capacity is required. It is responsible for protocol processing and

connection management, and implements controlling and managing the

service frames.

TDM



� MTNU

� It provide switching and subtending function, it has the master

station compare with the TCLU, it can provide all of the TDM

service switching include the frame TDM service switching which

the MTNU in.

� TCLU

� It provide switching and subtending function, but it can only

provide the frame’s TDM service switching which the TCLU in.


TNU

�The TNU, together with TDM service interface boards,

composes the T-S-T switching network for the whole

TDM system.

�Implementing one-plus-one backup. The subtending

optical fiber provides one-plus-one protection.


TCLU

�The TCLU, together with interface boards,

composes the switching network for the same

subrack.

�Implementing one-plus-one backup. The subtending

optical fiber provides one-plus-one protection.


TCU

� The TransCode Unit (TCU) provides voice coding/decoding

resources and echo cancellation resources, implements voice

packetization at TDM side, processes voice datagram, and

implements tone playing function

� The Echo Cancellation Unit (ECU) in the UMG8900 is used to

implement echo cancellation function for the voice signals.


S2L

�Implementing clock and data recovery of two 155-M

optical interfaces.

�Processing overheads of regenerator section and

multiplex section of optical signals and checking

communication through optical channel.

�Implementing mapping, demapping of SDH and

processing overheads of high-order path and low-order

path.

�Processing E1*63*2 framing and implementing DS0

switching of level-one TDM service.

Clock subsystem


CLK

�CLK is the system clock board, responsible for receiving line clock

signals extracted by interface boards and external synchronous

clock signals provided by BITS.

�Each MGW frame is configured with two NET boards. In the main

control frame, the clock boards provide 16-kHz clock signals to the

NET boards of the frame through the backplane. In other MGW

frames, the clock boards provide 16-kHz clock signals to the NET

boards through the distributed cables.

�The CLK also outputs external synchronous clock signals.

BLU


FLU

� The Front Link Unit (FLU) is the front subtending board of

UMG8900 in the case of multiple frames subtended.

� A couple of FLUs can provide 8-k time-slot of TDM data

subtending channel and 2x1.25 G of GE data subtending

channel for the corresponding back subtending board BLU.

� FLU has no interface.
