Opportunity
Growing demand for Ethernet services and increased availability of cost-effective
Ethernet infrastructures in metro access networks are creating new exciting
revenue opportunities for service providers. By enabling both PBX T1/E1
backhaul and Internet access to small- and medium-sized businesses over
a single high-speed Ethernet link, providers leverage next-generation
metro technologies to expand service offerings, increase revenues, and
cut costs.
Solution
Axerra’s AXN1 and AXN10
pseudo-wire access devices backhaul PBX T1/E1 voice circuits to the
PSTN over metro Ethernet or IP access infrastructures
using the industry’s most robust TDM pseudo-wire encapsulation
known as Circuit Emulation Service over Packet (CESoP). A unique feature
within the AXN1/10 also enables Dynamic Bandwidth CES (DB-CESoP) capabilities
of CAS/CCS-aware voice circuits and thereby optimizes bandwidth consumption
on the network uplink. At the CO (Central Office) / PoP (Point-of-Presence),
Axerra’s carrier-class AXN1600 or AXN800 pseudo-wire gateways
aggregate, terminate, and groom multiple CES or DB-CES flows into channelized
T1/E1,
T3/E3, and OC-3/STM-1 interfaces for cost-effective integration with
class-5 switches.
Benefits for Service Providers
• Leverages next-generation metro technologies (e.g. Metro Ethernet,
RPR, IP Metro) for the backhaul of full-featured TDM voice and thereby
reduces Operational Expenses (OpEx) associated with TDM leased lines
• Protects “legacy” capital investment in PBX and class 4/5
switches while eliminating new investments in VoIP
• Enables efficient bandwidth utilization between residential and business
customers through dynamic bandwidth allocation between voice and data (DB-CESoP)
