During the last decade, pseudowire technology has

been established as the de-facto enabler for

migrating legacy communications services to

economical, higher bandwidth packet switched

networks (PSNs). Today, TDM pseudowires are

implemented in many mainstream services,

transparently carrying voice, video and data traffic

end-to-end over Ethernet, IP or MPLS backbones.

What are TDM pseudowires?

Pseudowire (PW) emulation is a method for transmitting

any Layer 2 protocol over packet switched networks. It

allows a seamless connection between two network

elements by creating logical links, or virtual tunnels,

across the packet network. In TDM pseudowires, the

transmitted E1, T1, E3, or T3 streams are encapsulated in

packets upon entering the network and then

reconstructed at the pseudowire egress, where clocking

information is also regenerated. As a result, real-time

traffic is delivered transparently without distortion,

avoiding the complexities of translating signaling data,

while ensuring that synchronization criteria are met.

The pioneering author of various pseudowire RFCs,

recommendations and implementation agreements, RAD

has been actively involved in the creation of the industry’s

major pseudowire standards by the IETF, ITU, MFA, and

MEF. Since first introducing TDMoIP pseudowire

encapsulation to the market in 1999, RAD has deployed

more than 60,000 pseudowire links worldwide. Our vast

expertise and industry-leading know-how create field-

proven solutions that ensure service continuity for TDM

applications, with full support for legacy equipment, such

as Class 4 and 5 switches, PBXs and TDM multiplexers.

RAD’s TDM pseudowire expert solutions

RAD offers a diverse mix of TDM pseudowire access

gateways – from small customer-located equipment, to

high-capacity aggregation units for central offices or

points-of-presence (POPs). The IPmux family of TDM

pseudowire gateways (see pages 172-179) handles full

E1/T1, fractional E1/T1 and E3/T3 streams right off the

user premises, while the Gmux-2000 (pages 180-181)

offers a modular chassis for aggregating and terminating

pseudowire traffic. Together, they provide circuit

extension over packet with VLAN-based service

differentiation, using any media, including fiber, copper,

HFC, microwave, and satellite access. In addition, the TDM

pseudowire access gateways incorporate dedicated ASICs

featuring all standard TDM pseudowire modes, with end-

to-end QoS and OAM attributes to meet service-specific

performance criteria.

RAD also offers innovative TDM pseudowire gateways in

an SFP (small form factor pluggable) format, maximizing

user flexibility with a simple and cost-effective alternative

to conversion cards. Designed for quick and simple

insertion into any Fast Ethernet device port with a

compatible SFP socket, the MiTOP-E1/T1 and MiTOP-E3/T3

simplify management and save on space, power

consumption and cabling (see page 182).

Compelling benefits

RAD’s TDM pseudowire access gateways offer a high

degree of flexibility in determining the migration path to

packet transport by allowing access agnostic delivery of

all services and transmission protocols. Other benefits

include:

• Enabling end-users to keep their existing equipment

• Eliminating the need to invest in separate, service-

dedicated networks

• Supporting quick and non-disruptive upgrade of legacy

services to future-ready networks

• Simplifying network management, maintenance and

operations

• Allowing more users to be served by the same

infrastructure

Who benefits from TDM pseudowires?

Incumbent carriers cut operating expenditures (OpEx)

and minimize customer churn by converging legacy traffic

with new revenue generators, such as E-Line and E-LAN

services, over cost-effective PSNs.

Alternative service providers and cable operators

with packet-based infrastructure grow their customer

base by adding traditional leased line and private line

services to their Layer 2 portfolio.

Enterprises

reduce their IT expenses on PSTN

connectivity and branch-to-branch communications by

consolidating PBX, ISDN BRI, video, and data traffic over a

single, economical Ethernet link.
