LPU

LPU: Line interface Processing Unit

LPU provides physical interfaces to

the external network (SGSN, PDN,

RADIUS, CG), including FE, GE, POS,

ATM etc.

LPU only response transmitting packet

between PDN and WCDMA/GPRS

network.

LPU receive the route table from SRU.

DMPU Subcard

The DMPU subcard implements enhanced

service features on the SPU. It functions as a

universal service processing card to perform new

service processing functions.

The DMPU subcard provides the hardware

accelerated DPI function.


14/35


DMPU Subcard

The DMPU subcard can be inserted

into the reserved subcard slot of the

SPU.

One SPU can be equipped with one or

two DMPU subcards. The subboardcommand is used to

enable the DMPU subcard to the SPU

in the specified slot. The undo

subboardcommand is used to disable

the DMPU subcard to the SPU in thespecified slot.

You must reset the SPU after changing

the configurations on the SPU.


15/35


Position of the DMPU Subcard on the SPU

One SPU can be equipped with one or

two DMPU subcards.

The red frame in the figure shows the

position of the DMPU subcard(s) on theSPU. If two heat dissipation panels are

removed, two DMPU subcards can be

inserted.


16/35


DMPU Subcard

If a DMPU subcard is installed but not enabled by using the

command, the DMPU subcard cannot provide correspondingfunctions.

If a DMPU subcard is not installed but is enabled by using the

command, the DMPU subcard cannot provide corresponding

functions and an alarm is generated.

The two DMPU subcards can work in load-sharing mode. If one

DMPU subcard fails, the other DMPU can take over all services

and a fault alarm is generated.

If the DMPU subcard is required but no DMPU subcard is available,

or if the DMPU subcard is overloaded, an alarm is generated.
