SIU Site Integration Unit
What is the SIU •
The Site Integration Unit is a 1U-high, 19-inch mobile site router and aggregation 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
SIU Components -Power
• The SIU can be supplied with power from an RBS or another external 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.
SIU Components -Console Port
•
The CONSOLE (IP/Ethernet) interface is used for connection of a local maintenance terminal.
•
Accessed locally via telnet, remotely via SSH
•
Local SIU IP address: 192.168.0.1
•
Login: User : admin Password: hidden
SIU Components -Clock Port
•
The CLOCK interface includes both the clock input and the clock output interfaces.
•
Both interfaces use 1PPS signals with RS-422 electrical levels.
SIU Components -E1/T1 Ports
•
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 Packet Switched 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 -Ethernet Ports
•
Eight triple-speed Ethernet GE connectors (numbered 0 through 7)
•
The connectors marked 0a, 1a, 2a, and 3a are shared with the corresponding SFP connectors (marked 0b, 1b, 2b, and 3b).
•
The combo-interfaces allow for either Ethernet or SFP to be used at a time and which one used is determined by its configuration.
•
The Ethernet connectors have built-in LED indicators. The indicator to the left is lit when a link is established and flashes during activity.
SIU Components -SFP Ports
•
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, and 3a) it is shared to.

SIU Commands -Transactions StartTransaction: This command starts a basic CM transaction. Only one basic CM transaction can be active at the time. (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 -Configuring for Remote Operation •
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 IP address of the OSS master host) Example: setMOAttribute trans1 STN=0 wakeUpRegistration 10.10.42.254
•
Create an instance of MO IPInterface Example: createMO trans1 STN=0,IPInterface=0
SIU Commands -Configuring for Remote Operation •
Set the IP address, subnet mask, and default gateway for the primary IP interface Example: setMOAttribute trans1 STN=0,IPInterface=0 primaryIP_Address 10.10.10.254 setMOAttribute 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
SIU Commands -Configuring for Remote Operation •
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
SIU Commands -Configuring for Remote Operation •
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 depLinkLayer STN=0,EthernetInterface=WAN
SIU Commands -Configuring for Remote Operation •
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
SIU Commands -Backup •
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 -Restore •
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 to activate it is done
Example: -download bcm1 sftp://smith:
[email protected]/STNCFG/stn82_synch.xml -restore bcm1 admin
