Services Enabled by EFM

As the rate and reach achievable with EFM suggest, the 
most attractive application for the technology is simply 
the delivery of much higher bandwidth services for SMOs 
and cell sites at more affordable rates.  As a rule of 
thumb, operators are able to offer profitable EFM band-
width today at about 1/6 the service charge per Mbps of 
T1/E1.  The flexible bond group design of EFM allows 
customers to easily migrate from one bandwidth level to 
the next by adding pairs one at a time.

Beyond just more bandwidth, the native Ethernet archi-
tecture of EFM also enables a number of other value-
added services, which create tiered pricing opportunities 
for operators.  These include:

E-Line Services

 — Also known as Ethernet Private Line 

(EPL), are point-to-point services over Ethernet in the 
access network, generally Internet or VoIP connections.  
These can also include VPN services. This is also an 
alternative to traditional Frame Relay, as well as fractional 
or full T1/E1 service and even dial-up service.

E-LAN Services

 — Also known as Transparent LAN 

Service (TLS), E-LAN involves using Ethernet access-
network connectivity to create a seamless Ethernet LAN 
extension from the subscriber/enterprise network to the 
WAN & across the WAN to other locations. It is consid-
ered a native Ethernet multi-point service using Layer 2 
functionality.  E-LAN services are an attractive alternative 
to Frame Relay and IP VPN services over T1/E1 infra-
structure.

SLA E-LAN

 Services — SMOs that are part of larger 

organizations often need guaranteed bandwidth for TLS 
services between their locations, to support mission-
critical applications.  Adding Service Level Management 
via IP SLA provides an added value service tier for these 
customers.

TDMoE Services

 — Some service providers merely use 

Ethernet as a simplified means of delivering T1/E1 TDM 
services due to the attractive operating economics.  
TDMoE is transparent to the end subscriber, who still 
sees a T1/E1 rate connection.  TDMoE with a carefully-
controlled clock reference for TDM timing-critical 
applications (such as cellular voice backhaul) is also 
known as pseudo-wire, or PWE.

Easy, Fast Implementation

Beyond the higher bandwidth and advanced services EFM 
supports, the technology also offers service providers 
substantial time to market advantage and operating 
savings, from its simplicity and flexibility in network 
design, installation, turn-up, and maintenance.  Especially 
when embodied in a well-integrated and scalable multi-
service access platform approach, as with Zhone’s EFM 
portfolio, the equipment is capable of supporting a wide 
range of configurations, from single point-to-point 
installations through very high density aggregation, all 
within the same interoperable hardware and software 
architecture.
