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 E in section Additional information.
BTS name
NAME = text string
EQ - Base Transceiver Station Handling in BSC EQE MODIFY BTS IDENTIFICATION PARAMETERS
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 E 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 E 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 E in section Additional information.
new BTS name
NEWNAME = text string
With this parameter you define the new name of the BTS. The name can contain 1 to 15 characters and it must be unique in the BSC. The following ASCII characters are allowed: letters from A to Z and numerals from 0 to 9.
You can remove the name by giving the character '-'. See Example 4.
new SEG name <option>
NEWSEGNAME = text string
With this parameter you define the new name of the segment. The name can contain 1 to 15 characters and it must be unique in the BSC. The following ASCII characters are allowed: letters from A to Z and numerals from 0 to 9.
You can remove the name by giving the character '-'.
cell identity
CI = decimal number
With this parameter you identify the cell number. The values range from 0 to 65535.
You must also update the incoming adjacency definitions with the commands of the EA command group. For more information, see section 'Modifying the location area (LA) or the cell identity (CI) of a BTS' in Radio Network Administration.
EQ - Base Transceiver Station Handling in BSC EQE MODIFY BTS IDENTIFICATION PARAMETERS
With this parameter you define the number of the network colour code. The values range from 0 to 7.
When you modify this parameter, the corresponding parameter of the adjacent cells is automatically modified.
BTS colour code BCC = decimal number
With this parameter you define the number of the BTS colour code. The values range from 0 to 7.
When you modify this parameter, the corresponding parameter of the adjacent cells is automatically modified.
mobile country code MCC = decimal number
With this parameter you define the number of the mobile country code. The values range from 0 to 999.
☞
You can modify this parameter only when GPRS has been disabled in the BTS (the value of the parameter GPRS enabled is N).mobile network code MNC = decimal number
With this parameter you define the number of the mobile network code. The values range from 0 to 99.
Optional values range from 0 to 999.
☞
You can modify this parameter only when GPRS has been disabled in the BTS (the value of the parameter GPRS enabled is N).☞
Because the value of the mobile network code parameters (MNC, MNC1...MNC10, TMNC, and NEWMNC) in the entire GSM network is a binary-coded decimal number, the preceding zeros are significant. For example 1, 01, and 001 are different values.The use of a one-digit MNC is not allowed.
location area code LAC = decimal number
With this parameter you define the location area code. The values range from 1 to 65533.
☞
You can modify this parameter only when GPRS has been disabled in the BTS (the value of the parameter GPRS enabled is N).You must also update the incoming adjacency definitions with the commands of the EA command group. For more information, see section 'Modifying the location area (LA) or the cell identity (CI) of a BTS' in Radio Network Administration.
BTS hopping mode
With this parameter you define the frequency hopping mode of the BTS. When you modify the parameter, the BTS must be in a LOCKED state.
Radio frequency hopping is not possible in the 2nd generation base stations.
