Ethernet/VLAN Interface Function
The indoor 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 indoor 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 indoor SPI-2210 can support better performance service and convenience by supporting
various auxiliary devices.
Wireless Backhaul Interface
The indoor SPI-2210 can mount a wireless backhaul device provided by a service provider
by adding auxiliary shelf to mount additional auxiliary devices. An auxiliary shelf of the
indoor SPI-2210 is equipped with a Power Distribution Panel-Premium Auxiliary (PDP-PA) to
supply the power to the wireless backhaul device. When the server that manages the
wireless backhaul device exist, the indoor 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 indoor SPI-2210 receives or sends alarm history from/to outside through UDA.
The indoor SPI-2210 provides a total of 24 UDA Rx ports and 10 UDA Tx ports.
The indoor 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 indoor SPI-2210 provides the Ethernet interface to connect auxiliary devices and allocates
IP addresses by operating as a DHCP server for the auxiliary devices such as TTLNA.
In addition, the indoor 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 indoor SPI-2210 carries out the NAT
function to change the address into a public IP address (i.e., the IP address of the indoor
SPI-2210) for the communication with an external monitoring server.
