OMU Board

System management board of main control frame(SSM256). Provide BAM function. Inserted in slot 7, 8 and work in 1+1 backup. Providing FE switching for internal control and signaling traffic.

MOMB System management board of main control frame(SSM32). Provide BAM function. Inserted in slot 6/7, 8/9 and work in 1+1 backup. Providing GE switching for IP voice traffic.

MOMU

Configured in SSM32 Slot 6/7, 8/9. Providing GE switching for IP voice traffic. Work in1+1 backup.

System management function is implemented by MTNC. Only packet service is required, the MMPB is configured.

MMPB

MHRD is a back board, which equals the combination of HRU + G1O or HRU + E8T.D8FT subboard is inserted in the UG01MHRD1, which provides eight fast Ethernet (FE) interfaces.D1GO subboard is inserted in the UG01MHRD2, which provides one gigabit Ethernet (GE) interface.The ports on the UG02MHRD can work in load-sharing or master/slave mode.

MHRD

Provide GE switching function in SSM256 frame

UG02MNET provides 2*GE and 4*FE cascading interfaces

Receive clock signal from CLK and distribute the clock signal to TDM processing boards within the frame

Work in 1+1 backup mode

MNET

MTNB configured in SSM256 frameProviding 256k TDM switching functionProvide 4*8k TDM cascading connectingSupport 1+1 backup work modeMTNB is inserted in back plane slot 6 & 9

MTNB

Implementing the core function of the signaling gateway by supporting the M3UA//M2UA/V5UA/IUA adaptation on signaling, and forwarding adapted messages to the media gateway controller (MGC).

Receiving signaling from TDM switching units through theSubboard (SHPU), and processing the TDM signaling.

MSPF

The MVPD enables the following functions:

- Supporting functions such as announcement playing, digit collecting, audio mixing and MFC.

- Implementing IP packet adaptation of voice services based on UDP, RTP and IP.

MVPD

MTNC is configured in SSM32 frame

MTNC provides device management function (MPU function)

UG01MTNC can support 32k TDM switching functionUG02MTNC can support 96k TDM switching function

MTNC supports FE switching function for control plane and internal signaling traffic.

MTNC provides clock function through CKMB sub-board

MTNC can receive 16 KHz stratum-2 clock from CLK and deliver 8 KHz clock through the TDM cascading path between frames

MTNC

MCLKs are inserted in back slots 0 and 1 in the main control frame and work in 1+1 standby mode.

The MCLK can be inserted in both SSM-256 frames and SSM-32 frames.

MCLK can generate stratum two clock signal

MCLK

They can be inserted in both SSM-256 frames and SSM-32

The ME32 enables the following functions: - Providing 32 E1 interfaces.- Providing 32 E1 frames.- Providing the function of drawing the line signaling of the R2 signaling or inserting the signaling

ME32

ECUEcho canceller unit.

It is a front board used for ECHO canceling.
