SIUSite Integration Unit


2/19

The Site Integration Unit is a 1U-high, 19-inch mobile site router andaggregation unit

The SIU aggregates the traffic from an RBS site (GSM, WCDMA, LTE,

CDMA) for a shared connection across the transport network

Supports Packet Abis traffic to GSM RBSs

Supports up to 16 E1 interfaces

Implements VLANs

What is the SIU


3/19

The SIU can be supplied with power from an RBS or anotherexternal power supply delivering -48 or +24 V DC.

It is possible to connect the SIU with DC power on.

Built in over protection but if a fuse is used, the recommended

fuse size is 6A.

4/19

The CONSOLE (IP/Ethernet) interface is used for connection of alocal maintenance terminal.

Accessed locally via telnet, remotely via SSH

Local SIU IP address: 192.168.0.1

Login:

User : admin

Password: hidden

SIU Components-Console Port


5/19

The CLOCK interface includes both the clock input and the clockoutput interfaces.

Both interfaces use 1PPS signals with RS-422 electrical levels.

SIU Components-Clock Port


6/19

Sixteen E1/T1 transmission connections can be used as: ML-PPP interfaces

Abis lower connections to GSM RBSs

General-purpose E1/T1 interfaces in Circuit Emulation Service over PacketSwitched Networks

E1/T1 interfaces in High-Level Data Link Control (HDLC) over IP

Connections are configured in software

The E1/T1 connectors have two built-in LED indicators, one for each interface.

(The indicator is lit when the transmission path is functioning)

SIU Components-E1/T1 Ports


7/19

Eight triple-speed Ethernet GE connectors (numbered 0 through 7)

The connectors marked 0a, 1a, 2a, and 3a are shared with the correspondingSFP connectors (marked 0b, 1b, 2b, and 3b).

The combo-interfaces allow for either Ethernet or SFP to be used at a timeand which one used is determined by its configuration.

The Ethernet connectors have built-in LED indicators. The indicator to the leftis

lit when a link is established and flashes during activity.

SIU Components-Ethernet Ports


8/19

Four SFP (Small Form-Factor Pluggable)connectors (numbered 0 through 3)

The markings 0b, 1b, 2b, and 3b indicates

which Ethernet connector (0a, 1a, 2a, and3a) it is shared to.

SIU Indicators

Indicator Colour Status Explanation

Fault Red On One or more major alarms are detected; the SIU must be

replaced.

Power Green On The SIU has power.

Oper Green Flashing at 10Hz An active SFTP(1) or SSH(2)

session

On The SIU is operational

Flashing at 0.5Hz The SIU has power but is not

operational

SIU Indicators

Indicator Colour Status Explanation

Sync Green On The SIU provides sufficient timing to RBSs

Off Timing provided by the SIU cannot be used by RBSs

Info Yellow On One or more minor alarms are detected; the SIU must be

replaced.

Off No faults were detected

SIU Commands-Generic


12/19

StartTransaction:

This command starts a basic CM transaction. Only one basic CM transaction can be active at thetime. (E.g. startTransaction trans1)

GetTransactionStatus:

Idle, CommitFailed, CommitCompleted(E.g. getTransactionStatus trans1)

Commit:

Commits all configuration requests in the transaction

EndTransaction:

If performed before commit, all changes in the transaction are lost.

(E.g. endTransaction trans1)

SIU Commands-Transactions


13/19

Start a basic CM transaction

Example: startTransaction trans1

Set the unique network name (maximum 18 characters) for the SIU

Example: setMOAttribute trans1 STN=0 STN_Name KISTA_39

Set the IP address to which the SIU must send a wake-up registration (the IPaddress of the OSS master host)

Example: setMOAttribute trans1 STN=0 wakeUpRegistration 10.10.42.254

Create an instance of MO IPInterfaceExample: createMO trans1 STN=0,IPInterface=0

SIU Commands-Configuring for Remote Operation


14/19

Set the IP address, subnet mask, and default gateway for the primary IP

interface

Example:

setMOAttribute trans1 STN=0,IPInterface=0 primaryIP_Address 10.10.10.254setMOAttribute trans1 STN=0,IPInterface=0 primarySubNetMask 255.255.255.0

setMOAttribute trans1 STN=0,IPInterface=0 defaultGateway 10.10.10.1

Set the references to the IP interface assigned for O&M traffic towards OSS,

in this example the primary IP interface

Example: setMOAttribute trans1 STN=0 depIP_Interface STN=0,IPInterfac e=0



15/19

Configure the desired type of WAN interface to be used

Example: createMO trans1 STN=0,EthernetInterface=WAN

Set the value of the physical port to either "Gigabit" for ports 0-7 (electrical

interface) or "SFP" for ports 0-3 (optical interface)

Example: setMOAttribute trans1 STN=0,EternetInterface=WAN port Gigabit



16/19

Set the physical port number (0-7) to be used

Example: setMOAttribute trans1 STN=0,EthernetInterface=WAN portNumber 3

If needed, set the attribute mode to be used. The value "AUTO" means that the

mode will be negotiated and the interface speed agreed will be utilized

Example: setMOAttribute trans1 STN=0,EthernetInterface=WAN mode AUTO

Set the dependency link layer between the IP interface and the Ethernet

interface

Example A: setMOAttribute trans1 STN=0,IPInterface=0 depLinkLayerSTN=0,EthernetInterface=WAN



17/19

Commit command required to activate the configuration

Example: commit trans1

If attributes that require a restart are changed, the commit command is

rejected and has to be reissued with the forcedCommit parameter

Example: commit trans1 forcedCommit

End the transaction

Example: endTransaction trans1



18/19

Backs up the SIU configuration file.

Example:

backup bcm1sftp://smith:[email protected]/STNCFG/stn82_CM.xml admin

SessionId: bcm

FileRef: sftp://username:password@host/filepath

Passwd: admin

The password to be used for encryption of the configuration file and is used when

performing a restore.

SIU Commands-Backup


19/19

A restore is executed in two steps; using the commands download and restore

During restore:

The backed up configuration is downloaded from the provided SFTP path

Decrypted (using the restore command) with the same password as entered when the file was backed up, finally an attempt toactivate it is done

Example:

-download bcm1 sftp://smith:[email protected]/STNCFG/stn82_synch.xml

-restore bcm1 admin
