Terms
MAID
Maintenance Association Identier. An identier for a Maintenance Association, unique over the OAM domain. The MAID has two parts: the MD
Name and the Short MA Name. A MAID is equivalent to the ITUs term MEG ID.
MD
Maintenance Domain. The part of a network for which faults in connectivity can be managed.
ME
Maintenance Entity. A point-to-point relationship between two MEPs within a single MEG.
MEG
Maintenance Entity Group. Equivalent to a Maintenance Association (MA). A set of MEs that exist in the same administrative boundary, with the
same MEG Level and MEG ID.
MEG-ID
Maintenance Entity Group Identier. Equivalent to the IEEE term Maintenance Association Identier (MAID). An identier for a MEG, unique over
the domain that SOAM is to protect against the accidental concatenation of service instances.
MEP
Maintenance association End Point [IEEE 802.1ag], or equivalently MEG End Point [ITU-T Y.1731]. An actively managed SOAM entity associated with
a specic service instance that can generate and receive SOAM PDUs and track any responses. It is an end point of a single MEG, and is an endpoint
of a separate Maintenance Entity for each of the other MEPs in the same MEG.

1. Summary
Initially based on the rec. ITU-T G.984.x (GPON), our active network equipment solution is nowadays evolving for next generation PON architec-
tures as dened by the recs. ITU-T G.987.x, ITU-T G.988.x and ITU-T G.698.x whether central oce and/or customer premises.
Reference Point-to-Multipoint (P2MP) FTTx topology scenarios cover Fiber-to-the-Home (FTTH), Fiber-to-the-Building (FTTB), Fiber-to-the-Curb
(FTTC), Fiber-to-the-cell (FTTc) and Fiber-to-the-business (FTTb) as depicted at Figure 1 -1.
Ethernet service customers are also addressed by P2P links and Ethernet interfaces with dedicated bitrate allocation as also depicted at Figure 1
-1.
The OLT is a high availability and high reliability high density scenario Optical Line Termination (OLT) equipment specially designed for ber
network infrastructures in Point-to-Multipoint (P2MP) FTTx Gigabit Passive Optical Network (GPON) architectures in urban deployment scenarios.
Supporting up to 48 PON ports OLT can be considered the best-of-breed market oer in terms of future proof central oce optical equipments.
This equipment is intended to solve all your ber access needs in terms of retail as well as wholesale clients. It complies with ITU-T G.984x and
is able to serve multiplay services, namely Voice (VoIP), Data (High Speed Internet - HSI), TV (IPTV and RF Overlay) of up to 3072 client premises
(assuming a 1:64 Splitting ratio) from a single chassis.
Wholesale and enterprise services are addressed through Business Ethernet VBES/TLS Services (Vlan Business Ethernet Services/Transparent
VLAN Services). Up to 144 client premises can be supported at the P2P topology from a single chassis.

2. Technical Description
The OLT system is a reliable modular Optical Line Termination (OLT) equipment specially devoted for ber network infrastructures either Point-to-
Point (P2P) Ethernet or Point-to-Multipoint (P2MP) FTTx Gigabit Passive Optical Network (GPON) architectures.
The OLT supports Voice, Data and Video services. In parallel the transport of analog video services (RF Overlay) can be supported. Carrier class TDM
services bridging is also available by means of using dedicated network termination equipments (NTA).
The OLT is a reliable high availability system that uses common element 1+1 protection (Power, Switch Fabric & Processing) and load balancing
LACP at the Uplink interfaces. To guarantee security the Advanced Encryption Standard (AES) is used in the system. Multicast and IGMPv2/v3
snooping with proxy reporting are both enablers for a exible IPTV service delivery.

Figure 2-2. OLT architecture
Figure 2 -2 shows the architecture of OLT 1T1 equipment. It consists of a closet for the placement of the two switching boards and linecards (a
maximum of three). In this equipment the interface to the core network is implemented in the switching boards.
The linecards may be any of the existing in the systems OLT 1T1, OLT 1T2 or OLT 1T3.
