Upside beyond Bandwidth
Note that in establishing back-of-the-envelope business
case views of these three operator classes, the value of
more advanced services (such as E-LAN connectivity or
tiered performance and pricing based on SLA levels) has
not been incorporated. Whether included as part of the
baseline service in order to provide more tangible differ-
entiation of the offer in an effort to gain share, or offered
as incremental charges, the low cost of implementing
these additional features in EFM solutions will yield even
more upside to all three operator models.
Finally, the business case for cell site applications is
largely analogous to each of the three cases sketched out
above — whenever the cellular operator must buy back-
haul from the open marketplace, i.e. it is not the wireless
arm of an operator group that includes wireline services
that can be purchased at cost. For wireless operators
with wireline assets, the case for EFM can be based on
more bandwidth over limited copper resources, compara-
tively lower maintenance and operating costs than for
legacy interfaces, or avoiding the costs of more expensive
alternatives such as microwave or fiber build-out.
Zhone’s Extensive EFM Solution
Portfolio
Zhone continues to play a pioneering role in the Ethernet
over Copper and EFM marketplace. From embracing and
carrying forward the early work of Net to Net, to launch-
ing our first 802.3ah standard products in 2006, equipping
one of the largest EFM deployments to date (at over
60,000 lines) in 2007, and most recently adding SHDSL
EFM support to our benchmark-setting MXK™ intelli-
gent terabit access concentrator, we continue to set the
pace in truly scalable, carrier-class EFM solutions.
Our EFM portfolio includes a unique combination of:

Access
Architecture
•
Scalability
- From 2 to 480 ports per chassis available
on Zhone’s MSAP platforms
•
Multi-Service Access Platform integration
- Zhone’s
EFM solutions integrate with its MSAP platforms
allowing carriers to deploy multiple access services
from a single, high bandwidth Zhone platform
•
G.SHDSL or T1/E1 bonding
- Numerous bonding
performance advantages including: 1) Aggregate rate
of bond group delivered via copper pairs of unequal
rate performance, 2) Continuous operation of lose
pair and bond group even if one pair is lost, and 3)
hitless adds or drops of pairs completed with ease.
•
Carrier Class redundancy and platform design
-
Zhone’s SLMS based platforms meet all carrier
requirements enabling carriers to easily integrate
Zhone platforms into their network and launch EFM
services efficiently.
•
Extensive Pseudowire Support, with multiple timing
options
- Carriers can connect TDM networks with
IP networks and recover timing seamlessly, and
•
Full Management Automation
- Comprehensive path
measurements are generated for a complete view of
the EFM network and fast IP SLA resolution.
•
Touchless Provisioning
- Customers can simply
connect the Zhone EADs to the Zhone MSAP
platforms and have EFM services live in minutes.
