Metaswitch IMS Access Gateway Control Function (AGCF)
The IP Multimedia Subsystem (IMS) is ready to deliver on its promise of all-IP telephony, transitioning operators from being facilities-based to being true software telcos, while protecting their investment in transmission equipment and maintaining service continuity. As part of an IMS solution, Metaswitch’s Access Gateway Control Function is a critical component in the evolution of the telco network and the march towards network functions virtualization (NFV).
An Access Gateway Control Function (AGCF) in a PSTN Emulation Subsystem (PES) enables an IMS network to communicate with legacy non-SIP access networks through an Access Media Gateway (A-MGW).
Metaswitch’s AGCF is the result of more than a decade’s experience helping service providers to build next-generation and IMS networks, enabling you to migrate your TDM network to VoIP and IMS in complete confidence.
With multiple deployment models and theoretically unlimited scalability, the Metaswitch AGCF is a powerful and flexible solution for A-MGW control in IMS architectures.
Unique software + standard hardware = flexibility
Architected as a pure software solution, Metaswitch’s advanced AGCF is not dependent on any proprietary equipment. Deployed as standard on high-performance commercial off-the-shelf ATCA hardware, or available to install on your choice of generic server, the AGCF is easy to install and maintain, and can scale for the future.
You can deploy the Metaswitch AGCF exclusively with the Metaswitch Universal Media Gateway (UMG) and MetaSphere Multiservice Telephony Application Server (MTAS); or in a multi-vendor environment; or with any other IMS-compliant A-MGW and TAS.
You can integrate the AGCF with the UMG for a compact and efficient solution. If the AGCF does not need to be in the media path, eg in pure MGCP or NCS access networks, you can deploy the AGCF without the UMG.
The AGCF is suitable for deployment in IMS or pre-IMS networks.
As big as you want, as reliable as you need
You can run multiple AGCF instances side-by-side to scale to millions of subscriber lines, with no theoretical limit to how big your network can grow.
A fully redundant system architecture allows the AGCF to retain full operational capability in the event of an individual component fault, and geo-redundancy protects against regional failures.
