VOIP service, OLT only configures L2/Multicast information for VEIP interface and
leaves routing service to ACS’s business.
3.1 VoIP
The same as pure ONT release. Please see section 2.1.
3.2 VEIP
The OLT must configure all the VLAN/p-bit used by different services: HSI, IPTV,
Management and VOIP. (The VOIP interface is reserved for future ACS-controlled
VOIP service. In currently release, it is not supported yet.). Also, the Multicast
channel VLAN used for IPTV service. It should treat the virtual Ethernet interface
just like an Ethernet Port to allow the traffic coming RGW could pass OLT correctly.
After OLT has well configured the L2 path for VEIP interface, the RG service could
be controlled by remote ACS via TR069 protocol.
Before ACS could reach I-241W-U, one WAN connection used to connect to ACS
server and ACS server information must be configured first in I-241W-U to make
sure I-241W-U could communicate with remote ACS and it could be configured by
local management interface: Web and TR-064.
3.3 RG interfaces
Basically, the embedded RG in I-241W-U provides up to two LAN interfaces and up
to 4 WAN connections in WAN side and it is shown in following figure.
