1.1 Hardware Overview

Cabinet

The SGSN9810 system consists of one or

more cabinets. Each cabinet can be configured

with a maximum of four subracks.

Subracks are numbered 0, 1, 2, and 3 frombottom to top. Generally, subrack 0 is the basic

subrack and other subracks are extended

subracks. Slots 0 and 2 in the basic subrack

are configured with OMUs.


7/59



Basic Subrack

The OMU subrack is configured as the

basic subrack for the UPBA 2. In the basic

subrack, the back board of the SWUA is

the SWIA 1.

The basic subrack is responsible for the

whole-system configuration, maintenance,

alarm and performance management, and

service exchange between boards. In

addition, it also provides interfaces for

external services.


8/59



Expansion Subrack

The subracks other than the basic subrack

are called expansion subracks.

The expansion subrack processes services.

In the expansion subrack, the back board of

the SWUA is the SWIA 0.

1.3 Interface Overview

PFI Interface

Each EEC provides four Ethernet electrical interfaces.

Each EFC provides four Ethernet optical interfaces.

Each AIC provides a combination of ATM interfaces at various

rates as listed below:

Two 622 Mbit/s optical modules and two 155 Mbit/s optical

modules

One 622 Mbit/s optical module and three 155 Mbit/s optical

modules

Four 155 Mbit/s optical modules

Operating mode: The ATM, FE, and GE interfaces support the 1+1 backup mode.

Duplex mode: Only Ethernet interfaces support the duplex mode.

Full duplex: Both sides of communications can transmit data at the same time regardless of

the communication media status or conflict detection. The principle of the full duplex mode is

transmission on demand.

Half duplex: Only one side of communications can transmit data at a time. Before

transmitting data, the interface constantly monitors the communication media. If the interface

detects signal collisions on the communication media, it delays the data transmission andthen retransmits the data.

Transmission rate: The rate of an Ethernet optical interface is 1000 Mbit/s. The rate of an

Ethernet electrical interface is 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s.

Negotiation mode: The combination of a transmission rate and a duplex mode forms the

operating mode of an interface. The self-negotiation technology is created to simplify the

networking configuration and solve interface interconnection problems. Based on this technology,

the devices shake hands through pulse negotiation signals so that both sides work in the highestoperating mode supported.

Maximum transmission unit (MTU): When an interface receives a message that is larger than

the defined MTU of the interface and is marked with "partition not allowed", the SGSN9810

discards this message and returns an ICMP error message to inform the sender of the reason

why the message is discarded. Then, the sender sends a smaller message.

Attributes of the PFI Interface


18/59



XGI interface

The XGI provides four GE interfaces and one

10GE interface.


19/59



Operation mode: GE interface or 10GE interface

Duplex mode:

Full duplex: Both sides of the communication can transmit data at the same time

regardless of the communication media status or conflict. The principle of the full

duplex mode is transmission on demand.

Rate Type: 1000 Mbit/s for the optical GE interface or 10000 Mbit/s for the

optical10GE interface.

Negotiation mode: It does not support auto-negotiation.

Maximum transmission unit (MTU): When an interface receives a message that is

larger than the specified value of the MTU and is marked with "partition not allowed",

the SGSN9810 discards this message and returns an ICMP error message to inform

the sender of the reason why the message is discarded. Then, the sender sends a

smaller message.

E1/T1 Interface

The ETI provides the E1/T1 interface.

The basic attributes of the E1/T1 interface include

the code type, frame format, and transmission mode.

Attributes of the E1/T1 Interface

Interface Type Frame Format Code Type Transmission Mode

E1 DF or CRC HDB3 or AMI ShortLine or LongLine

T1 D4, ESF, or F4 B8ZS or AMI ShortLine or LongLine


22/59



ETI interfaces and PFI interfaces use different numbering rules.

Each ETI provides 32 E1/T1 interfaces, which are numbered from 0

in ascending order from bottom to top.

Each PFI provides eight interfaces, which are numbered from 0 in

ascending order from top to bottom.

As the entity for hardware management, the rack must be added before other

hardware. Plan the rack number based on actual information about the

equipment room, that is, the room number and actual position of the rack.

The command interface is as follows:

28/59



When you add the first subrack, you must set Subrack numberto 0.

When you add a subsequent subrack, set Subrack numberto a number

that is not in use. In actual applications, Subrack numbermust be the

same as the number specified by the DIP switch on the subrack. Position

numberindicates the position number of a subrack in a rack. The

subracks in a rack are numbered 0 to 2 from bottom to top.

Slot number of SRMUindicates the numbers of the slots where the

SRMU 0 and the SRMU 1 reside. The SRMU is responsible for subrack

management on the ATCA platform. By default, the SRMUs are configuredin slots 0 and 1. According to the requirement of the SGSN9810, the

SRMU needs to be deployed on the ECU. Therefore, you must manually

change the slot numbers. For example, change the slot numbers to 1 and

3.

Adding a Subrack (ADD SUBRACK)


29/59






30/59



The added subracks are all ATCA subracks. The version of a subrack

is consistent with the actual physical model.

Configure the R3 subrack to support both broadband and narrowband.

The subrack version is T8280. The configuration script is as follows:

ADD SUBRACK: SRN=0, RN=0, PN=0, SBVER=T8280, SRMUSN1=1,

SRMUSN2=3, SWFBRDT=SWUA1, SWBBRDT=SWIA1;

The subracks delivered to customers are all R3 subracks. The

switching unit is the SWUA 1; the back board in the basic subrack is

the SWIA 1; the back board in an expansion subrack is the SWIA 0.
