TDM-over-IP Gateways, Multiplexers & Cross Connects
ForeFront FF-T3-SFP T3 TDMoIP Gateway SFP Module

This unique SFP Module is a miniature TDM over IP/Packet gateway. Now you can transport T3 over Ethernet/IP/Packet networks using Pseudowire technology with the convenience of a Small Form Pluggable Module.

• TDM-over-IP SFP - Transports T3 (DS3) over IP/Packet using SAToP (RFC4553) Pseudowire technology.
• T3 Support - T3 (44.736 Mbps) on a 75 Ohm mini coax 6.6 mm.
• Plug and Play - No providing or configuration required. Plugs into SFP slot in a Switch, Router or Media Converter (1000BASE-X).
• Circuit Emulation - Saves money. Eliminate TDM leased line costs. Suitable for Enterprise/Business access and enables the migration of T3 access links to packet.
• Interoperable - Interoperates with other SAToP T3 equipment
• Standards Based - Packetization done using SAToP (RFC4553) with less than 1ms of latency (several timing modes supported). MEF8 and MPLS frame header format optional VLAN tag. T3 Jitter and wander tolerance and acceptance according ITU-T G.824. Packet Delay Variation tolerance according test cases defined in ITU-T G.8261, Appendix VI, section 4. Differential clock recovery (DCR).
• MSA Compliant - Electrically MSA compatible and INF-8074 Compliant SFP. GbE in accordance with IEEE Std 802.3-2008. The MSA side works in SerDes mode.
• Diverse Applications - Supports migrations and back haul operations of 5G Mobile Operators, Telecom Service Providers, Utilities, Transportation, Oil & Gas, Government, and Energy customers.
• Optional API - Optional Software API for Remote Management.
• Industrial Design - Industrial temperature range -40�C to 85�C.

The ForeFront FF-T3-SFP is an innovative TDM-over-IP Gateway packaged in an SFP module. The device is a new, convenient and easy way to transport T3 (DS-3) across an Ethernet network.

The unit utilizes the SAToP (RFC4553) protocol to convert T3 data into a single stream of Ethernet packets (Pseudowire).  The units can be used in pairs or with other SAToP devices.

Small Form Factor Pluggable 20-pin Multi-Source Agreement (MSA) compliant, the unit can be installed in any Router, Switch our Media Converter with Ethernet SFP slots.

The internal circuit ground is connected to the SFP metal housing. The cable ground is connected, via the coax connector, to the SFP metal housing.

The unit integrates structure-agnostic TDM over packet technology (SAToP) into a miniature and cost-efficient module, reducing system and network complexity while delivering CAPEX and  OPEX savings.  It can aggregate T3 into channelized SAToP links enabling each T3 to be handled individually providing high-density TDM over IP/MPLS gateway functions.

These units are deployed in networks for major 5G mobile operators, and communications service providers, as well as mission-critical networks for Utility, Transport, Oil & Gas, Government, and Energy.

The devices are most typically installed in Ethernet/IP/MPLS Switches, Cell site Routers, Microwave Radio Systems or WDM systems.

The ForeFront FF-T3-SFP is a plug-and-play device which can be used without any provisioning and simplifies configuration and service turn-up of T3 connections across a packet network.  Optionally, an API is available to facilitate integration in existing equipment and management systems. This management interface allows configuration and helps to monitor relevant parameters.

The FF-T3-SFP is packaged in ruggedized SFP and supports operating temperatures from 40°C to 85°C.

The typical use-case is a point-to-point pseudo-wire emulation from SFP to SFP.   Individual tunnels are created to separate the pseudo-wire traffic.  The FF-T3-SFP uses a multi-cast destination MAC-address; Each pseudo-wire needs to be put into a separate Ethernet tunnel using VLAN, EVC, MPLS, VPLS or VPWS.  The units are ‘plug-and-play’ and no configuration is needed.
