LTP-8X optical line terminal

Chapter 2.

Application

LTP-8X optical line terminal is designed to establish connection with upstream equipment and provide

broadband access over passive optical networks. Ethernet connection is established through Gigabit

uplink and 10G Base-X interfaces; GPON interfaces are used to connect to optical networks. Each

interface can provide connection for 64 subscriber optical terminals through one fibre and supports

dynamic bandwidth allocation (DBA).

The following services are provided to end users:

— voice communications;

— HDTV;

— VoIP telephony (based on SIP/H.323/MGCP protocols);

— high-speed Internet access;

— IP TV;

— video-on-demand (VoD);

— video conferencing; and

— online educational and entertainment programs.

The device has the following functions:

— dynamic bandwidth allocation (DBA);

— support of quality assurance mechanisms (QoS), GPON ports prioritization for different types of

traffic according to 802.1p;

— security functions;

— ONT remote control, automatic detection of new ONT;

— FEC errors correction;

— power measurement support for signals received from each ONT (RSSI) 1

— VLAN organisation (VLAN ID range: 0-4094);

— MAC address filtering, 16,000 records in the MAC addresses table;

— support of IGMP snooping v1/2/3, IGMP proxy;

— support of DHCP snooping, DHCP relay agent; and

— support of PPPoE IA.
