INTRODUCTION NetAct is not just an Alarm monitoring tool - instead, it provides us with an interface interact with the network in a very efficient manner. Though it does not involve any fancy GUI, but little effort put into understanding of the interface results in a very positive grip over ones abilities of troubleshooting and problem localization.

1 Checking the status of a site G THE STATUS OF A SITE: The command used to check the status of a particular site is: ZEEI SYNTAX: ZEEI: BCF=BCF#; (Ex. ZEEI:BCF=63; for BCF 63)
Where BCF means Base Control Function. Its main tasks are base station operation and maintenance functions, that is, software loading, unit configuration, and alarm handling. Consider the screen shot given below:
11
Legend:
1 – Site ID 2 - BTS Number (it’s unique within a BSC) 3 – Operational Status of a Site / BTS / TRX 4 – Frequency at which the particular TRX is working 5 – This is the ET/PCM number serving this particular site 6 – This highlights the particular TRX having the BCCH channels (as TRX-001 and TRX-004 in the case) 7 – Current number of half rate calls on a particular BTS 8 – Current number of full rate calls on a particular BTS 9 – Base Control Function number for the site 10 - Current Status of O&M link of the site 11 – Current number of data calls (GPRS) on a particular BTS

2 EXTRACTING THE CURRENT/OLDER ALARMS For current alarms we use the ZEOL command: Syntax: ZEOL;
(Gives current alarms of all the BTS/BCF of the BSC)
ZEOL: BCF#; (Ex: ZEOL:45; for BCF 45 gives current alarms of the particular BCF mentioned)
For alarms history we use the ZEOH command: ZEOH: YYYY-MM-DD, HH-MM-SS: BCF=BCF#;
YYYY-MM-DD stands for the date since which you want to extract the alarms. While HH-MM-SS stands for the time since which you want to extract the alarms.
ZEOH:: NR=ALARM#YYYY-MM-DD, HH-MM-SS;
This will extract the history of this particular alarm since the day and time given.
3 Locking/unlocking a site On NetAct MML there are commands that enable you to lock/unlock a TRX, a Sector (BTS) or the whole site (BCF).
ZEFS: This command is used to lock and unlock a site Syntax:
Locking a Site:
ZEFS: BCF#: L; (Ex: ZEFS:135:L; for BCF 135)
This will lock the whole site bringing it to BL-USR state. Unlocking a Site:
ZEFS: BCF#: U; (Ex: ZEFS:135:U; for BCF 135)
This will unlock the site bringing it to BL-RST state. The site can only be unlocked if it is in BL-USR state.
ZEQS: This command is used to lock and unlock a BTS (sector) Syntax:
Locking a Sector:
ZEQS: BTS=BTS#:L; (Ex: ZEQS:BTS=228:L; for BTS 228 )
This will lock the sector (BTS), bringing it to BL-USR state. Unlocking a Sector:
ZEQS: BTS=BTS#:U;
This will unlock the sector (BTS), bringing it to BL-RST state. The sector can only be unlocked if it is in BL-USR state. NETACT MML (Nokia 2G) basic training V 1.0a - Bruno Cardoso - Lockdown Team
ZERS: This command is used to lock and unlock the TRX. Syntax:
Locking a TRX:
ZERS:BTS=BTS#,TRX=TRX#:L; (Ex: ZERS:BTS=69,TRX=1:L for BTS 69, TRX 1)
This will lock a TRX, bringing it to BL-USR State. Unlocking a TRX:
ZERS:BTS=BTS#,TRX=TRX#:U;
This will unlock a TRX, bringing it to a BL-RST state. The TRX can only be unlocked if it is in a BL-USR state.
4 Resetting a site ZEFR: This command is used to reset a site or it’s OMU. Syntax:
Resetting a Site:
ZEFR:BCF#:SITE;
This command is used to reset a site automatically while avoiding the BL-USR state. This is a lengthy process and takes around 2-5 minutes. Resetting an OMU:
ZEFR:BCF#:OMU;
This is used to reset the O&M Link of a part icular BCF. Many a times we don’t need to give a reset to the whole site. Instead a reset to its OMU automatically helps recover dif ferent sectors which might be blocked.
5 NOTES There are different types of blocked states which are briefly defined below: BL-SYS: When the TRX is blocked but the Lap- D’s are in working state BL-RSL: When the TRX is blocked and the Lap- D’s are also blocked BL-BCF: When the whole BCF is blocked. BL-TRX: When the TRX is faulty. BL-USR: When the TRX is intentionally blocked by the User. All commands that we will be using start with an Z and always end with the ; (semi-colon) and you need to press the “ENTER” key after each command.
Ctrl + B repeats last and previous commands on the MML Ctrl + Y interrupts current command being typed or run NETACT MML (Nokia 2G) basic training V 1.0a - Bruno Cardoso - Lockdown Team
