the active port on the BSC/RNC initiates two BFD sessions to
detect interface IP addresses of the routers. If two BFD sessions
on the active port detect faults, the standby port initiates one
Address Resolution Protocol (ARP) detection session to detect the
virtual IP address of VRRP (see note 1).
(2) If the routers do not support BFD, ARP detections are initiated
on both the active and standby ports of the BSC/RNC. The ARPdetection duration on the active port must be longer than that on
the standby port. Otherwise, invalid switchovers may occur.

Clock Server Configuration
On the GSM/UMTS network, it is recommended that the NodeB
provides a port for transport network connection and that the
interface IP address be configured on a NodeB transmission board.
The BTS connects to the NodeB through the backplane tunnel.
(1) The interface IP address IP1 and the device IP address IP2 are
configured on the NodeB. All services on the NodeB use IP2.
(2) The device IP address IP3 is configured on the BTS. All
services on the BTS use IP3. Both the transmission on the GSMnetwork and the transmission on the UMTS network use the
interface IP address IP1.
IP Address Configuration for the Ethernet Interface on the
BTS/NodeB
It is rcommended that the interface IP address be different from the
device IP address for the GSM/UMTS dual-mode base station,

(1) The interface IP address IP1 is configured on the NodeB. All
services on the NodeB use IP1.
(2) The transmission on the GSM network is not separated from

configuration for the BTS/NodeB, and configure redundant routes.
The route configuration in the non-pooled networking scenario is as follows:
(1) The high-priority routes for the data with the destination IP address of
IP151 are configured on the active transmission interface board, and the next-
hop IP address of the route is IP10. The low-priority routes for the data with
the destination IP address of IP151 are configured on the standby
transmission interface board, and the next-hop IP address of the route is
IP20.(2) The high-priority routes for the data with the destination IP address of
IP111 are configured on the standby transmission interface board, and the
next-hop IP address of the route is IP20. The low-priority routes for the data
with the destination IP address of IP111 are configured on the active
transmission interface board, and next-hop IP address of the route is IP10.
In the pooled networking scenario, the primary and secondary routes are
configured on the basis of the source IP address.
The conditions for switchover between the active and standby boards on the
BSC/RNC are as follows:
(1) The Bidirectional Forwarding Detection (BFD) is enabled on the active and
standby transmission interface boards of the BSC/RNC and the routers
directly connect to the boards. If the BFD detects faults on a board, the
BSC/RNC deactivates all routes configured on the board and uses thesecondary route.
(2) If the routers do not support BFD, the primary/secondary route switchover
based on the physical port status is recommended to be configured for the
BSC/RNC.
(3) The Address Resolution Protocol (ARP) detection cannot be used by the
route switchover on the RT1/RT2 and cannot ensure reliability. Therefore, the
ARP detection is not recommended to be configured on the BSC/RNC.

Note 2: On the SRAN, the low-priority packet switched (PS) services on the GSM network are combined to hiaccess (HSPA) services on the UMTS network.

1The clock system is not required if the BSC/RNC provides only the
FE/GE Ethernet ports.
Pay attention to the following when configuring the line clock:
1. If TDM ports are configured on the Core Network (CN) side, clock
signals can be obtained from the CN. The following lists in
descending order the CN NEs from which clock signals can be
obtained: media gateway (MGW) > mobile switching center (MSC)
server > home location register (HLR) > serving GPRS support
node (SGSN).
2. If TDM ports are configured on the BTS/NodeB side but not onthe CN side and if the clock signals on the intermediate SDH
network meet the quality requirements, the BSC/RNC obtains clock
signals from the SDH network. If the SDH network uses E1/T1
electrical ports, the electrical ports must be set to retiming mode.
3. If the line clock is used, the clock board must be configured in the
MPS.
If the BSC/RNC uses time division multiplexing (TDM) ports, such
as E1, T1, STM-1, or STM-4, a clock system must be configured.
The external clock source can be the building integrated timing
supply (BITS), Global Positioning System (GPS), external 8 kHzclock, or line clock.
The clock server is recommended to be directly connected to
routers without using the BSC/RNC.
The transport network meets the QoS requirements of the clock
server. The 1588v2 unicast solution is recommended.1
If the clock server is not configured, any of the following
BTS/NodeB synchronization schemes can be used: GPS,
synchronous Ethernet, external BITS, and line clock. 3

If the line clock is used, the error rate of the line clock must be less than
50 ppm.
Direct routes must be configured from routers to the active and standby
clock servers.
The minimum bandwidth for each BTS/NodeB is 16.5 kbit/s, and the
maximum bandwidth for each BTS/NodeB is 66 kbit/s.
If the line clock is used, the error rate of the line clock must be less than
50 ppm.
Neighboring transmission devices of the BTS/NodeB must supportEthernet synchronization, ensuring that the clock error rate is less than 50
ppm.
