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 siteG 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:

Legend:

1Site ID

2 - BTS Number (itsunique within a BSC)

3Operational Status of a Site / BTS / TRX

4Frequency at which the particular TRX is working

5This is the ET/PCM number serving this particular site

6This highlights the particular TRX having the BCCH channels (as TRX-001 and TRX-004 in the case)

7Current number of half rate calls on a particular BTS

8Current number of full rate calls on a particular BTS

9Base Control Function number for the site

10 - Current Status of O&M link of the site

11Current number of data calls (GPRS) on a particular BTS

2 EXTRACTING THE CURRENT/OLDER ALARMS

For current alarms we use the ZEOLcommand:

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.

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 its 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 particular BCF. Many a times we dont need to give a reset to

the whole site. Instead a reset to its OMU automatically helps recover different 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-Ds are in working state

BL-RSL: When the TRX is blocked and the Lap-Ds 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
