Technical Description

Q_PPS_DM_018_V1.3

For the IPTV service the XGS-PON Fiber Gateway also behaves like a Layer 2 bridging device. For this

service, the XGS-PON Fiber Gateway has a specific XGEM PORT for Multicast. This same XGEM

PORT is requested by the user in order to have access to the various IPTV channels. Every time a user

requests a new channel, the XGS-PON Fiber Gateway will send to OLT a IGMP packet requesting that

Channel. The XGS-PON Fiber Gateway is also responsible for implementing the snooping for the

channels that the user requests.

2.9.2 Voice interfaces

XGS-PON Fiber Gateway voice service provisioning could be made through OLT configurations over

OMCI messages or could be downloaded (FTP) from the OLT up to the XGS-PON Fiber Gateway after

its registration on the PON network. XGS-PON Fiber Gateway equipments have the ability to deliver the

Voice service over two types of interface:

2.9.2.1 Physical interface (FXS ports)

The XGS-PON Fiber Gateway has physical RJ11 FXS interfaces terminated in the equipment by means

of FXS (RJ11) connections. The RJ11 analog terminals adapter function is auto/self-configured,

integrated (analog/VoIP) and associated with a defined SIP or Megaco (H.248) user.

The XGS-PON Fiber Gateway will allow VoIP or NGN (Next Generation Network) traffic from devices

connected to the RJ11 or RJ45 interfaces, towards the same internal VLAN.

Apart of the SIP and Megaco (H.248) self-configuration, it is also possible to make modifications in the

voice service configurations by updating the XGS-PON Fiber Gateway SW through download from the

OLT via OMCI.
