Security Features

Tellabs has implemented unique advanced security features to protect enterprise networks. The ONT203W supports security across the optical distribution network and end-to-end over the OLAN system; such as encryption of traffic on the PON using the Advanced Encryption Standard AES-128 and Access Control Lists (ACL) at Layer 2 through 4 levels.

The ONT provides for advanced dynamic assignment of services to a port via the use of Network Access Control (NAC) with fall back to a Guest VLAN. The ONT supports IEEE 802.1x port-based authentication and MAB. This prevents unauthorized access to ports, and offers RADIUS authentication for users and enforcement of policy to end users based on their login.

Components

The ONT203W is modular in design so that its Power Module, ONT Module and Faceplate can be purchased and installed separately.

Connectors

The FlexSym ONT203W module has 5 connectors:
 

• DC 54V - DC power input. This is a special power connector that mates with a Phoenix-type pluggable terminal connector (5.08 mm pitch 2P), allowing remote bulk DC power to be used. (Remote DC power is limited to 100 VA by code.)
• GE1 - GE2 - Two (2) high powered 10/100/1000 Gigabit Ethernet ports that provide up to 60W of PoE.
• MG3 - One (1) IEEE 802.3bz and 802.3an port that supports 10M/100M/1G/2.5G data rates with auto-negotiation. This port supports up to 60W of PoE.
• Fiber Optic Connector - This is the optical port for connecting the ONT to the upstream Optical Line Terminal (OLT) over a fiber-optic cable. It is a standard replaceable SC/APC-type connector for Single-Mode Fiber (SMF) cable. The connector is protected by a small, black plastic insert in shipping.

Note: GE1, GE2, and MG3 are high power ports that support up to 60 watts of PoE.

Indicators

The front of the ONT has the following LED indicators:

• PON - shows status of the Passive Optical Network (PON)
• GE1 - MG3 - shows status of the three service ports

LED Behavior

LED	Indications		Comments
PON		Red	The PON is currently down. ONT is not receiving a signal from the OLT

		Green Blink Slow	The board is performing a software download.
		Green	The PON is up and operating normally.
		Dark	The ONT is booting
GE1-GE2, MG3		Green	• Link (Up)  • PoE (No PD Detected)  • Data (No data detected)

Manual Controls and Switches

The ONT has only one user-operable control:

• Reset - This momentary pushbutton switch resets the ONT. The Reset switch pushbutton is accessible through a small hole on the front of the ONT.
