TDM-over-IP Gateways, Multiplexers & Cross Connects
ForeFront FF-T1E1-SFP T1/E1 TDMoIP Gateway SFP Module

This unique SFP Module is a miniature TDM over IP/Packet gateway. Now you can transport T1 or E1 over Ethernet/IP/Packet networks using Pseudowire technology with the convenience of an Small Form Pluggable Module.

• TDM-over-IP SFP - Transports T1 or E1 over IP/Packet using SAToP (RFC4553) Pseudowire technology.
• Plug and Play - No providing or configuration required. Plugs into SFP slot in a Switch, Router or Media Converter (1000BASE-X).
• T1 or E1 Support - E1 2.048 Mb/s 120 Ohm balanced and T1 1.544 Mb/s 100 Ohm balanced (RJ45 connector).
• Interoperable - Interoperates with other SAToP E1/T1 equipment.
• Standards Based - Packetization done using SAToP (RFC4553) with less than 1ms of latency (several timing modes supported). MEF8 and MPLS frame header format. Jitter and wander compliant to MEF18, ITU-T G.8261 and G.823/4. MSA compatible and INF-8074 Compliant SFP.
• 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 - Rugged packaging and industrial temperature ranges from -40�C to 85�C.

The ForeFront FF-T1E1-SFP is an innovative TDM-over-IP Gateway packaged in an SFP module.  The device is a new, convenient and easy way to transport T1/E1 (DS-1) across an Ethernet network.

The unit utilizes the SAToP (RFC4553) protocol to convert T1/E1 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 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 T1/E1 into channelized SAToP links enabling each T1/E1 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.

Network transformation, including all-IP migration is the goal of most network operators.  However, most maintain a TDM transport capability on their packet networks for the following reasons:

• Customers are using TDM circuits for leased lines and are unable to migrate quickly.
• Mobile Backhaul for GSM or LTE still depends on T1/E1/DS1.
• Legacy Enterprise Voice equipment relies on T1/E1/DS1 .
• Operators seek to preserve revenue streams from high-valued TDM services.
• Some customers require highest reliability and mission-critical SLAs for their TDM circuits, such as tele-protection
• Some Providers are obliged by contract or law to deliver TDM services.

 

The ForeFront FF-T1E1-SFP is a plug-and-play device which can be used without any provisioning and simplifies configuration and service turn-up of T1/E1 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-T1E1-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-T1E1-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.

Convert E1/T1 signals to packet with the FF-T1E1-SFP and aggregate using multiple SFPs or with other SAToP equipment.  Useful for mobile backhaul and legacy customers such military, railway, energy.
