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.
If you give this parameter and the segment contains more than one BTS, you can modify only BTS-specific parameters. See table BTS-specific parameters in command X in section Additional information.
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.
If you give this parameter and the segment contains more than one BTS, you can modify only BTS-specific parameters. See table BTS-specific parameters in command X in section Additional information.
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.
If you give this parameter and the segment contains more than one BTS, you can modify only segment-specific parameters. See table SEG-specific parameters in command X in section Additional information.
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.
If you give this parameter and the segment contains more than one BTS, you can modify only segment-specific parameters. See table SEG-specific parameters in command X in section Additional information.
HSCSD TCH capacity minimum HTM = decimal number
With this parameter you determine the minimum TCH capacity in percent which is offered to HSCSD (High Speed Circuit Switched Data) calls in the cell. In low traffic load situation, the HSCSD calls can have more TCHs than indicated by the parameter. Also, the minimum HSCSD capacity may not always be reached due to single-slot traffic con-gestion.
The values range from 0 to 100%.
HSCSD cell load upper limit HCU = decimal number
With this parameter you determine the upper limit in percent for cell load when the multi-slot TCH allocation is stopped and the single-multi-slot allocation is started for the HSCSD (High Speed Circuit Switched Data) calls.
When the cell load is greater than the upper limit and the minimum HSCSD capacity is reached, only one channel is allocated for new non-transparent HSCSD calls, transpar-ent HSCSD calls are not started and one of the currtranspar-ent HSCSD calls is downgraded for every incoming call. Downgradings are stopped and transparent HSCSD calls are allowed when either the number of HSCSD TCHs drops below the minimum HSCSD capacity or the cell load decreases below the upper limit.
The values range from 0 to 100%.
HSCSD cell load lower limit HCL = decimal number
With this parameter you determine the lower limit in percent for cell load when the single-slot TCH allocation is stopped and the multi-single-slot allocation is started and resource upgrades are allowed for the HSCSD (High Speed Circuit Switched Data) calls.
The values range from 0 to 100%.
HSCSD regular cell load upper limit HRCU = decimal number
EQ - Base Transceiver Station Handling in BSC EQX MODIFY DATA SERVICE PARAMETERS
<op-tion>
allocation is started for the HSCSD calls. Resource upgrades are not done in the IUO regular frequency area.
The values range from 0 to 100%.
HSCSD upgrade guard time HUT = decimal number
With this parameter you determine the guard time before a resource upgrade for a HSCSD call is executed after call setup, handover, ALA, resource upgrade, or resource downgrade. If you set the parameter to value 0, resource upgrade is not done.
The values range from 0 to 65535 seconds.
HSCSD downgrade guard time HDT = decimal number
With this parameter you determine the guard time before a resource downgrade for a HSCSD call is executed after call setup, handover, ALA, resource upgrade, or resource downgrade. If you set the parameter to value 0, resource downgrade is not done.
The values range from 0 to 65535 seconds.
HSCSD upgrade gain HUG = decimal number
With this parameter you determine the data rate gain which must be achieved before the resource upgrade can be done even though the upgrade guard time is not over.
The values are:
HSCSD minimum exhaust HME = decimal number
With this parameter you determine how much the data rate should decrease at least during the downgrade of an HSCSD call. The values range from 1 - 4:
Parameter Value Explanation
HUG = 0 % No upgrade during guard
time.
33 % Upgrade during guard time
if gain is at least 33%.
50 % Upgrade during guard time
if gain is at least 50%.
100 % Upgrade during guard time if gain is 100%.
Parameter Value Explanation
HME = 1 One TCH is always
released in downgrade.
2 Downgrade is made from
four to two, three to two, two to one TCHs.

after downgrade.
