Description

The Tellabs FlexSym ONT205 is part of the Tellabs 1600 series of ONTs for passive optical networks (PON). It is a compact desktop unit that can be mounted to almost any surface using an optional wall mounting bracket. It is plenum rated for above-ceiling applications.

The FlexSym ONT205 provides flexible and symmetrical extended Ethernet connectivity over a 10gigabit passive optical network at multi-rate Ethernet speeds of 1G, 2.5G, 5G and 10G.

The FlexSym 205 provides Power over Ethernet (PoE) for the IEEE 802.3af and PoE+ IEEE 802.3at (Class-4 negotiations) standards as well as support for Cisco UPoE. PoE of up to 60W is supported on 3 high power ports (GE1, GE2, and MG5). The maximum PoE power available is 140W when locally powered and 90W when remotely powered.

The FlexSym 205 can be deployed with the Tellabs OLT1150/OLT1150E, OLT1134/OLT6, FlexSym OLT1, FlexSym OLT2, FlexSym BOLT, and FlexSym OLT-mini Plus optical line terminals.

• QoS and security policies based on VLAN-ID, 802.1p, DSCP
• MAC address limiting to prevent flooding attacks and limiting the number of devices attached to a port
• IPv6 capable for enterprise services
• L2-L4 Access Control Lists (ACLs)
• Upstream ACL rate limiting
• Maximum Transmission Unit (MTU) 9216 bytes
• Supports Dante and CobraNet digital audio systems over IP
• IGMP v2/v3 snooping
• Link Layer Data Protocol (LLDP) for auto-provisioning, inventory and PoE power management.

Security Features

Tellabs has implemented unique advanced security features to protect enterprise networks. The ONT205 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 distribution of policy to end users based on their login.

Connectors and Indicators

Connectors

The back edge of the FlexSym ONT205 has 8 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.
• GE3 - GE4 - Two (2) 10/100/1000 Gigabit Ethernet ports that provide up to 30W of PoE.
• MG5 - One (1) IEEE 802.3bz and 802.3an port that supports 10M/100M/1G/2.5G/5G/10G data rates with auto-negotiation. This port supports up to 60W of PoE.
• Optical Connector (green). - 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: Revision E or above, GE1, GE2, and MG5 are high power ports that support up to 60 watts of PoE. Ports GE3 and GE4 are the only cables to provide up to 30 watts of PoE.

Indicators

The top of the ONT has the following LED indicators near the front edge:

• Power - shows status of the DC power input
• PON - shows status of the Passive Optical Network (PON)
• GE1 - MG5 - shows status of the five service ports

LED Behavior

LED	Indications		Comments
Power		Green	Input power is good for the ONT
		Dark	Power is off to the ONT or the power unit has failed.
PON		Red	The PON is currently down, ONT is not receiving a signal from the OLT.
		Green Blink Fast	The PON is up and ONT is attempting to register on the PON. If Auto Configuration is not enabled, use Unknown ONT option on the Panorama PON to register ONT.
		Green Blink Slow	The board is performing a software download.
		Green	The PON is up and operating normally.
		Dark	The ONT is booting
GE1-GE4, MG5		Green	• Link (Up) • PoE (No PD Detected)  Data (No data detected)
		Green Blink	• Link (Up) • PoE (No PD Detected) • Data (Data detected)
		Amber	• Link (Up) • PoE (Powering PD) • Data (No Data Detected)
		Amber Blink	• Link (Up) • PoE (Powering PD) • Data (Data Detected)
		Dark	The Ethernet Port is disabled, or the link is not 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 right-hand side of the unit (when viewed from the front).
