System Description
Chapter 3 System Function
3-21
I. Local cell configuration
This function is used to add or delete physical cell resources of the BTS. The unit of
physical cell configuration is sector-carrier.
The following configuration items are provided for this function:
Local cell ID, local sector ID, carrier ID, MTRB ID, maximum cell radius, maximum
user speed, maximum times of searching for reverse common channel, size of
service channel search window, search window offset, and power control mode.
II. Abis signaling link configuration
This function is used to configure the parameters for the Abis signaling link between
BSC and BTS. IPOA(Ip Over ATM) is adopted for Abis signaling link. Only one Abis
signaling link can be configured. If a configuration message is received when an Abis
signaling link already exists, it will be re-configured according to the new parameters.
The following configuration items are provided for this function:
Signaling IP address of BSC, signaling sub-net mask of BSC, VPI value of BSC
signaling link, VCI value of BSC signaling link, signaling IP address of BTS, signaling
sub-network mask of BTS, VPI value of BTS signaling link, and VCI value of BTS
signaling link.
III. Abis traffic link configuration
This function is used to configure the Abis traffic link between BSC and BTS. AAL2
adaptation is adopted for Abis traffic link. BTS3601C supports the configuration of
only one Abis traffic link. If a traffic link already exists upon the reception of a
configuration message, the traffic link will be re-configured according to the new
parameters.
The following configuration items are provided for this function:
VPI value of BSC traffic link, VCI value of BSC traffic link, VPI value of BTS traffic link,
VCI value of BTS traffic link, and PVC index of this traffic link.
IV. System clock source configuration
This function is used to configure the priority level of BTS3601C clock sources. The
three kinds of clock sources (in-borad clock source, internal clock source and external
clock source) can be configured with different priority levels, so that BTS can choose
the operation clock according to the priority level after startup.
The following configuration items are provided for this function:
