Overview of the MG 3200

The MG 3200 is the cost-effective, entry-level, market-ready, standards-compliant media
server systems. Intelligently packaged in a 1U chassis, especially designed for small-scale
deployments and smaller locations in the packet network, the MG 3200 is the correct
solution size for small-scale needs. Incorporating best-of-breed Voice over Packet
technology and based on field proven media technology, the MG 3200 enables Service
Providers (SPs) rapid time-to-market and reliable cost-effective deployments of enhanced
voice services in VoIP telephony networks. This compact device, is designed to be
installed either as a desktop unit or installed in a 19-inch rack.
The MG 3200 contains the TP-1610 cPCI VoIP communication board, an ideal building
block for deploying high-density, high availability Voice over IP (VoIP) enterprise systems.
The MG 3200 supports a broad selection of voice processing related algorithms, including
G.711, G.723.1, and G.729A Vocoders, G.168-2002 compliant echo cancelation, T.38 real-
time Fax over IP, a wide selection of In-band and Out-of-band tone detection and
generation, as well as signaling protocol support, including ISDN PRI, SigTran (M2UA,
IUA) and CAS.
The MG 3200 is suitable for VoIP gateways, IP-enabled call centers, large Telcos and next
generation DLCs. Offering integrated voice gateway functionality capable of delivering up
to 480 simultaneous calls, the MG 3200 supports all necessary functions for voice and fax
streaming over IP networks.
The MG 3200 incorporates up to 8 or 16 E1, T1 or J1 spans for connection, either directly
to PSTN telephony trunks, or to an enterprise PBX, and two 10/100 Base-TX Ethernet
ports for redundant connection to the LAN.
Two packet processors handle packet-streaming functions through two redundant integral
10/100 Base-TX interfaces. Each processor implements the industry-standard RTP/RTCP
packet-streaming protocol, advanced adaptive jitter buffer management, and T.38 fax relay
over IP. An E1/T1 trunk interface module is provided for 16-T1, or 16-E1, or 16-J1 trunks,
allowing for full gateway streaming functions in a single cPCI slot.
The TP-1610 board complies with industry-standard network control protocols including
H.248. These protocols allow for the implementation of a distributed Media Gateway and
media server architecture that separates call processing functions from media processing
functions, resulting in better redundancy, scalability and higher system availability.
Enabling accelerated design cycles with higher density and reduced costs, the MG 3200 is
an ideal building block for scalable, reliable VoIP solutions. With the MG 3200's
comprehensive feature set, customers can quickly design a wide range of solutions for
PSTN and VoIP networks.
