Multistandard Mixed Mode UMTS 900

4th sector splitting way of working

•Let’s assume Existing 3G site name 1234 & new site will be M1234

•Actions & Requirements from RNC side : 

1.Delete 2 Sectors form the Existing 3G site 1234.

2.Vodafone to send new scripts to create new logical site on RNC and OSS Named M1234.

•Actions & Requirements from Transmission side on site level

1.TCU must be on New schema (bridging Mode) which is the latest Vodafone standard.

2.If TCU is up and running on old schema (OSPF routing) so transmission action to change schema to bridging mode will be required. 

Actions & requirements on Site:

  

        1.Each DUW will be configured as single site.

2.Each DUW will be configured with two sectors UMTS 2100 and Two sectors      UMTS900

3.Each DUW will take different IPs from TCU using TCU bridging.

4.New logical site “M1234” will need New separate license.

5.OAM script and TCU scripts need to be created

•Take backup of TCU as usual

•

1.Open SFTP

2.Telnet to TCU via Winfiol on IP: 192.168.1.1 (username : Admin , password: hidden)

3.Run below commands to take backup using site ID instead of site name

•

uselocalsftp on

startsession 1

backup 1 sftp://TCU:TCU@192.168.1.2/TCU/site_name.xml   -u

getsessionstatus 1                                       

endsession 1                                             

uselocalsftp off

•Open new port on TCU and create 2 VLANs as per site LLD and Run below TCU part of script after modifying VLAN ID as per site LLD
