| MetaSwitch's Class
5 Softswitch is an ideal solution for greenfield, replacement, or cap &
grow Class 5 deployments.
POTS
POTS lines can be delivered via either traditional TDM
(GR-303) digital loop carriers or next-generation IP or ATM-based broadband
loop carriers.
MetaSwitch supports traditional POTS lines via digital and broadband loop carriers
This enables service providers to
- replace or augment a traditional Class 5 switch that
is running out of capacity or reaching end of life
- deploy digital loop carriers while avoiding the cost
of upgrading an existing switch with GR-303 capability
- move away from a proprietary host-remote architecture
to one based on industry-standard protocols
- steadily migrate from a circuit to packet-based network.
PBX SERVICES
MetaSwitch enables the delivery of carrier-class service
to subscribers with PBXs.
MetaSwitch supports PBX lines over a variety of TDM and packet interfaces
MetaSwitch's native TDM interfaces can be used for the
delivery of traditional T1/PRI services direct to PBXs over circuit-switched
T1 access lines.
Alternatively, MetaSwitch's support for broadband voice
capabilities enables service providers to deliver traditional T1 interfaces
to the customer's network over an IP or ATM network, with increased (and
more flexible and profitable) voice and data capacity compared with TDM
T1s.
Increasingly, PBX vendors are adopting the SIP standard
for VoIP connectivity to the PSTN. The MetaSwitch's support for SIP enables
service providers to deliver VoIP directly to such PBXs, in parallel with
more traditional connectivity options or as part of an IP Centrex solution.
CAP & GROW DEPLOYMENT
While MetaSwitch's Class 5 Softswitch can be easily deployed as a standalone
Class 5 switch, or to entirely replace an existing switch, many service
providers prefer to adopt a "cap and grow" approach. This leaves the existing
Class 5 switch in place, with shared SS7 links and/or TDM trunks.
MetaSwitch is particularly suited to
such applications. In particular, its "SS7 point code proxy" capability
enables deployment without changing any external network interfaces - it
doesn't even require a new SS7 point code!
The MetaSwitch Class 5 Softswitch is easily deployed in a "cap and grow" model
alongside legacy switches
As the diagram above shows, in addition to providing a
smooth migration path, such a deployment also offers a solution for compliance
with regulatory requirements such LNP and CALEA.
CASE STUDIES
See the Jaguar Communications,
Western Iowa and Yukon
Telephone case studies for examples of telephone companies who have
deployed MetaSwitch to deliver Class 5 services while steadily
migrating their networks to VoIP.
