Function With this command you define the BCCH allocation usage of the BTS or SEG. The command is optional.
Parameters BTS identification, BTS name, SEG identification <option>, SEG name <option>: iden-tification of BCCH frequency list, BCCH allocation usage for active MS, measurement BCCH Allocation list;
Syntax EQB : ( BTS = <BTS identification> ... | NAME = <BTS name> ... |
SEG = <SEG identification> ... <option> | SEGNAME = <SEG name> ... <option> ) :
( IDLE = <identification of BCCH frequency list> | ACT = <BCCH allocation usage for active MS>
MEAS = <measurement BCCH Allocation list> ) ... ; <option>
Parameter explana-tions
BTS identification BTS = decimal number
With this parameter you identify the BTS by its number. The value range depends on the BSC hardware configuration and the corresponding options.
If you give this parameter, you cannot give the parameters NAME, SEG, or SEGNAME.
You can use the parameters BTS, NAME, SEG, and SEGNAME if the segment has only one BTS; otherwise you must use the parameters SEG or SEGNAME.
You can enter several values at the same time by using the grouping characters & and
&& when you attach the same BCCH frequency list identification to several BTSs.
BTS name
NAME = text string
With this parameter you identify the BTS by its name. The name can contain 1 to 15 characters.
If you give this parameter, you cannot give the parameters BTS, SEG, or SEGNAME.
You can use the parameters BTS, NAME, SEG, and SEGNAME if the segment has only one BTS; otherwise you must use the parameters SEG or SEGNAME.
You can enter several values at the same time by using the grouping character & when you attach the same BCCH frequency list identification to several BTSs.
SEG identification <option>
SEG = decimal number
With this parameter you identify the segment. The value range is the same as the BTS identification value range.
If you give this parameter, you cannot give the parameters BTS, NAME, or SEGNAME.

You must use the parameters SEG or SEGNAME if the segment contains more than one BTS.
You can enter several values at the same time by using the grouping characters & and
&& when you attach the same BCCH frequency list identification to several segments.
SEG name <option>
SEGNAME = text string
With this parameter you identify the segment by its name. The name can contain 1 to 15 characters.
If you give this parameter, you cannot give the parameters BTS, NAME, or SEG.
You must use the parameters SEG or SEGNAME if the segment contains more than one BTS.
You can enter several values at the same time by using the grouping character & when you attach the same BCCH frequency list identification to several segments.
identification of BCCH frequency list IDLE = decimal number
With this parameter you define the BCCH frequency list used by idle MSS. This list is used for cell reselection and is sent on the BCCH.
The values range from 0 to 4200.
If the value is 0, the BCCH frequency list used is that of the adjacent cells defined for the BTS.
Do not connect the BTS to a BCCH frequency list which has no frequencies defined, because then the MS is not able to make handovers to other cells.
BCCH allocation usage for active MS
With this parameter you define the BCCH frequency list used by active MSS. This list is used for handovers and is sent on the SACCH. The values are:
Parameter Value Explanation
ACT = ADJ If the value is ADJ, the
BCCH frequency list used is that of the adjacent cells defined for the BTS.
Normally, the BTS operates this way.
IDLE If the value is IDLE, the active MSS use the same BCCH frequency list as the idle MSS. The BCCH frequency list is defined by the BTS. If the value of the parameter IDLE is 0, the active MSS use the BCCH frequency list of the adjcent cells.

measurement BCCH Allocation list
With this parameter you define whether or not Measurement BCCH Allocation List is used during measurements when necessary. The values are:
Examples 1. Attach BCCH frequency list 5 to BTS-2. The BCCH allocation for idle MSS is formed according to frequency list 5. The BCCH allocation for active MSS is formed accord-ing to the frequencies of the adjacent cells defined for the BTS.
ZEQB:BTS=2:IDLE=5;
2. Set both BCCH allocations to be formed according to the frequencies of the adjacent cells defined for the BTS CENTRUM1.
ZEQB:NAME=CENTRUM1:IDLE=0;
3. Attach BCCH frequency list 6 to BTS-3. The BCCH allocation for idle MSS is formed according to frequency list 6. Also, tell the active MSS to measure the frequencies in that list. The BCCH allocation for active MSS is formed according to the same fre-quency list as for idle MSS. Now, the active MSS may acquire some extra BCCH frequencies into their measurement routine, but nevertheless no handovers can be made towards those extra cells.
