Parameter explana-tions
BTS identification BTS = decimal number
With this parameter you identify the BTS with its number. The value range depends on the BSC hardware configuration and the corresponding options.
You can enter several values at the same time by using the grouping characters & and
&& when attaching or detaching the same DFCA mobile allocation frequency list to several BTSs. The value ALL attaches or detaches the same DFCA mobile allocation frequency list to or from all DFCA BTSs.
If you give this parameter, you cannot give the parameter NAME.
BTS name
NAME = text string
With this parameter you identify the BTS with its name. The name can contain 1 to 15 characters.
You can enter several values at the same time by using the grouping character & when you attach or detach the same DFCA mobile allocation frequency list to several BTSs.
If you give this parameter, you cannot give the parameter BTS.
mobile allocation frequency list
EQ - Base Transceiver Station Handling in BSC EQA MODIFY MOBILE ALLOCATION FREQUENCY
LIST USAGE PARAMETERS
The values range from 0 to 4200. Use value 0 to detach the BTS from the mobile allo-cation frequency list.
You can modify this parameter only when the BTS is LOCKED or the overlay hopping mode is not RF hopping.
underlay mobile allocation frequency list <option>
UMAL = decimal number
With this parameter you define the mobile allocation frequency list to which the BTS's underlay layer will be attached.
The values range from 0 to 4200. Use value 0 to detach the BTS's underlay layer from a mobile allocation frequency list.
You can modify this parameter only when the BTS is LOCKED or the underlay hopping mode is not RF hopping.
MAIO offset
MO = decimal number
With this parameter you set the lowest MAIO (Mobile Allocation Index Offset) value per sector. The values range from 0 to 62.
You can modify this parameter only when the BTS is LOCKED, underlay TRXs are LOCKED, or the overlay hopping mode is not RF hopping.
underlay MAIO offset <option>
UMO = decimal number
With this parameter you set the lowest MAIO value of the underlay layer per sector.
The values range from 0 to 62.
You can modify this parameter only when the BTS is LOCKED, overlay TRXs are LOCKED, or the underlay hopping mode is not RF hopping.
MAIO step <option>
MS = decimal number
With this parameter you choose the MAIOs not to be allocated successively for the cell, but for instance every second or every third value. The values range from 1 to 62.
You can modify this parameter only when the BTS is LOCKED, underlay TRXs are LOCKED, or the overlay hopping mode is not RF hopping.
underlay MAIO step <option>
UMS = decimal number
With this parameter you choose the MAIOs of the underlay layer not to be allocated suc-cessively for the cell, but for instance every second or every third value.
The values range from 1 to 62.
You can modify this parameter only when the BTS is LOCKED, overlay TRXs are LOCKED, or the underlay hopping mode is not RF hopping.
DFCA mobile allocation frequency lists <option>
DMAL = decimal number
With this parameter you define the DFCA mobile allocation frequency lists that will be attached to the BTS.
EQ - Base Transceiver Station Handling in BSC EQA MODIFY MOBILE ALLOCATION FREQUENCY LIST USAGE PARAMETERS
The values range from 1 to 64.
You can enter several values at the same time by using the grouping characters & and
&&. If more than one BTS identification or name has been given, grouping characters cannot be used.
DFCA MA list operation <option>
With this parameter you add or remove valid DFCA mobile allocation frequency list(s) to/from the BTS.
If you give this parameter, you must also give the DMAL parameter.
DFCA unsynchronized mode MA frequency list <option>
DUMAL = decimal number
With this parameter you define the DFCA unsynchronised mode MA list. The MA list is to be used in the DFCA TRXs if a BTS in 'DFCA hopping' mode loses synchronisation or BSC-BSC connection. This is a reference to any existing normal (non-DFCA) MA list defined in the BSC.
The values range from 0 to 4200. Use value 0 to detach the BTS from the DFCA unsyn-chronised mode MA frequency list.
Examples 1. Attach BTS-8 to mobile allocation frequency list 3 and set MAIO offset to 2.
ZEQA:BTS=8:MAL=3,MO=2;
2. Detach BTS CENTRUM1 from the mobile allocation frequency list.
ZEQA:NAME=CENTRUM1:MAL=0;
Additional informa-tion
(trx-1) * ms + mo < fma where
TRX= the number of underlay/overlay unlocked hopping TRXs in the cell ms= underlay/overlay MAIO step
mo= underlay/overlay MAIO offset
fma= the number of frequencies in the associated underlay/overlay mobile allocation frequency list
