TCU Description

› The TCU (Transport Connectivity Unit) is a component in the RBS 6000 product family and has been designed primarily to support Multi Standard RBS with advanced transport functionality.


TCU Description

› TCU provides the converged cell site with advanced transport functions, aggregating traffic from multiple digital units into One Pipe - a single, resilient IP interface for GSM, WCDMA, and LTE traffic


TCU Description

› The TCU provide dynamic aggregation of RAN and cell site traffic streams: Ericsson GSM Abis over IP, WCDMA NodeB Iub over IP, LTE EnodeB (S1, X2), TDM from legacy RBSs through circuit emulation services (CES) and IP traffic from other equipment on the RBS site.


TCU Description

› The internal highly stable Oven Controlled Crystal Oscillator (OCXO) of the TCU maintains the frequency needed to provide the connected RBSs with accurate timing via the E1/T1 interface or Clock Output (1PPS) interface.

› During operation, the TCU automatically calibrates the OCXO using one of the following methods: - According to the E1/T1 signal at the E1/T1 interface.

- Network Time Protocol (NTP) or Precision Time Protocol (PTP over UDP and PTP over Ethernet; IEEE 1588) time server(s) accessed through the IP transport network. - According to a SynchE (Synchronous Ethernet) Master reference on an Ethernet interface.


TCU Description

› TCU provides the following to the RBS site: › 8 Gigabit Ethernet ports for aggregation of traffic from multiple digital units › 4 T1 ports on TCU which carries 2 T1s per port for connecting GSM RBS cards (DUG) › Advanced shaping functionality for up to eight queues, with large buffer depth, supporting

highest LTE capacity. › Can act as an IP router and/or as an Ethernet bridge suiting all backhaul deployment

scenarios. › Supports NTP, 1588v2 and synchronous Ethernet for RAN synchronization. › Has a local oscillator with 12 months holdover time supporting synchronization over

virtually any backhaul technology, including satellite. › Provides Ethernet LAN/WAN connectivity for local site equipment › IP over the TDM (for migration) › Supports native IP transmission (Abis IP) for Ericsson GSM RBSs making a true All IP

multi standard RBS. › OSS-RC Management System guarantees smooth operations management.


Connecting from the PC to the TCU

› Connect the RJ45 cable to the LMT port on the TCU› Connect the other end to your PC

› The TCU does fit in a 6601 cabinet


Tools and settings required

› Crossed or straight thought cable › Setting Computer› SFTP server› Software Package› Terminal Emulator i.e. putty or secure CRT


Connecting from the PC to the TCU

› Connect the RJ45 cable to the LMT port on the TCU› Connect the other end to your PC

› The TCU does fit in a 6601 cabinet


Modify LAN settings on your PC

› Start Menu>Control Panel\Network and Sharing Center› Click on Manage Network Connections, right click Local

Area Connection and select Properties


Disable Protection

› Disable all Symantec processes: Control Panel AdminTools Services (Stop all process for Symantec.)› Disable firewall: Open Symantec Endpoint Protection

Change settingsClient Management Current location Out of Ericsson

Premises.


Setting Terminal Emulator

› Open a terminal emulator i.e. Secure CRT› Click on File and Select Quick Connect › Under Protocol Select Telnet and under Hostname enter

192.168.1.1 and on Connect› To log the sessionClick on File and select Log Session and type A file name


Setting Terminal emulator

› Open a terminal emulator i.e. Putty› Click on Session Select Telnet under Connection Type › Under Hostname enter 192.168.1.1 and under Saved

Sessions Type a Name click Save› Click on Open › To log the sessionClick on Logging and select All Session output and Always Append to


Verify current configuration and reset the TCU› Log into the TCUlogin: adminPassword: STN CLI – readyOSmon> revOSmon> getcontainment STN=0OSmon> resettofactorysettingWarning: All user settings will be removed, continue(ok/cancel)? okOperationSucceeded

Note : The TCU will restart and connectivity will be lost.


Save Software in C drive

› Create a directory under C:\ i.e C:\tcu› Unzip the software


Setting SFTP Server

› Open mini-sftp-server and change settings as belowType user: tcuPassword : tcuPort: 22Root: c:\


Upgrading the TCU

› Type the following commands to upgrade the TCUOSmon> uselocalsftp onOperationSucceeded

OSmon> startswsession 1OperationSucceeded

OSmon> downloadsw 1 sftp://tcu:[email protected]/tcu/tcu02_sw.tarOperationSucceeded

OSmon> getswsessionstatus 1DownloadInProgressOperationSucceeded


Upgrading the TCU

› Wait approximately 5 minutes for the software download to complete.

OSmon> getswsessionstatus 1DownloadCompletedOperationSucceeded

› When the software download is complete, activate the software using the following command:

OSmon> activatesw 1OperationSucceeded

› The TCU will restart and connectivity will be lost.


Upgrading the TCU

› Confirm that upgrade is complete type the commands belowOSmon> getswsessionstatus 1ActivationCompletedOperationSucceeded

OSmon> endswsession 1OperationSucceeded

OSmon> revOSmon> getcontainment STN=0


Troubleshooting Upgrade Tips

Downloading the software package is taking too long Check the logs and search for the the message below:OSmon> syslog read -s eventOSmon> syslog read -s system [1970-01-01T00:17:43.521+0000 L]

sftpclient:sftp_parser.c:197:INFO:SSH output: Connecting to 192.168.1.3...

Solution:› Make sure local sftp is used type command OSmon> uselocalsftp on› Update SFTP Server ( File Attached) msftpsrvr.zip


Load TCU Configuration Script› Turn SFTP on and make sure that SFTP server is running › Type the commands below to load the .xml fileOSmon> uselocalsftp onOperationSucceeded

OSmon> startsession 1OperationSucceeded

OSmon> download 1 sftp://tcu:[email protected]/tcu/tcu.xmlOperationSucceeded

OSmon> getsessionstatus 1DownloadCompletedOperationSucceeded


Load TCU Configuration Script› Activate the configuration once the download is completedOSmon> activate 1 OperationSucceeded

› The TCU will restart and connectivity will be lost

login: adminPassword: STN CLI - readyOSmon> endsession 1OperationSucceeded


Troubleshooting Tip TCU Configuration Script› Activation failed. Check the logs using the commands belowOSmon> syslog read -s eventOSmon> syslog read -s system
