Migration to IP/Ethernet
The prevalence of new Ethernet delivered
services requires increased investment in
new packet networks.
Customers demand the
continued support of non-Ethernet services
such as TDM voice and data which raises a
concern regarding the cost impact of
supporting two networks — one IP and one
TDM-based. With the ADTRAN
®
MX408e
Pseudowire Gateway, Ethernet service delivery
is consolidated onto a single multi-service
network supporting the delivery of cost-
effective broadband service and legacy service
revenue streams. ADTRAN’s pseudowire
solution reduces operational costs by retiring
expensive TDM leased lines.

Evolution to IP Backhaul
Service Providers are constantly looking for
ways to drive down the operating costs of
delivering both new broadband and legacy
voice services. As Triple Play, 1xEV-DO, PON,
HSPA, and IP Multimedia Subsystems (IMS),
drive the transformation of both the access
and core networks to IP, the backhaul network
that resides between must keep pace. Since it
is difficult to scale TDM backhaul as band-
width needs grow, long-term profitability is
not viable with TDM-based backhaul.
Pseudowire Extends the Value
of Ethernet Access
ADTRAN Pseudowire Ethernet solutions
enable the consolidation of service delivery
onto a single network. Operational costs can
be significantly reduced by retiring expensive
TDM leased lines and consolidating broad-
band and TDM voice services onto a single
Ethernet network. In many cases, ADTRAN
Pseudowire solutions can offer a six month
Return On Investment (ROI).
