Ethernet/VLAN Interface Function
The outdoor SPI-2210 provides the Ethernet interface and supports the static link grouping
function, Virtual Local Area Network (VLAN) function and Ethernet CoS function under
IEEE 802.3ad for the Ethernet interface. At this time, the MAC bridge function defined in
IEEE 802.1D is excluded.
The outdoor SPI-2210 enables several VLAN IDs to be set in one Ethernet interface and
maps the DSCP value of IP header with the CoS value of Ethernet header in Tx packet to
support Ethernet CoS.
2.2.4 Auxiliary Device Interface Function
The outdoor SPI-2210 can support better performance service and convenience by
supporting various auxiliary devices.
Wireless Backhaul Interface
Auxiliary device part of the outdoor SPI-2210 can mount a wireless backhaul device
provided by a service provider. The outdoor SPI-2210 supplies the power to the wireless
backhaul device.
When the server that manages the wireless backhaul device exist, the outdoor SPI-2210
supports the User Define Ethernet (UDE) port to provide path for maintenance traffic
between that server and wireless backhaul device.
UDA Support
The outdoor SPI-2210 receives or sends alarm history from/to outside through UDA.
The outdoor SPI-2210 provides a total of 24 UDA Rx ports and 10 UDA Tx ports.
The outdoor SPI-2210 provides UDA Tx 1 port to AICU for interoperation with TTLNA.
When subcell output of RAS is blocked by an operator command for the TTLNA receiver
test, the UDA informs the AICU that TTLNA becomes Rx only mode.
An operator uses UDA control commands to expand UDA ports, name UDA ports, and
transmit UDA Tx signals.
Auxiliary Device Interface
The outdoor SPI-2210 provides the Ethernet interface to connect auxiliary devices such as
TTLNA and allocates IP addresses by operating as a DHCP server for the auxiliary devices.
In addition, the outdoor SPI-2210 provides the traffic path to transmit/receive the
maintenance traffic between an auxiliary device and the remote auxiliary device
monitoring server.
If the auxiliary device uses a private IP address, the outdoor SPI-2210 carries out the NAT
function to change the address into a public IP address (i.e., the IP address of the outdoor
SPI-2210) for the communication with an external monitoring server.
