Gateway Description
The MP-40x (MediaPack) is an Integrated Services Digital Network (ISDN), Basic-Rate
Interface (BRI) VoIP media gateway. The MediaPack is best suited for small to medium
size enterprises, branch offices, or residential media gateway solutions implementing
ISDN. The MediaPack seamlessly migrates these environments to VoIP by connecting
legacy ISDN telephones, fax machines, and PBX systems (as well as for integration with
new IP-based PBX architecture) with BRI lines to the IP network. The MediaPack gateways
enable users to make free local or international telephone or fax calls between distributed
company offices, using their existing telephones or faxes. These calls are routed over the
existing network ensuring that voice traffic uses minimum bandwidth.
This stand-alone MediaPack BRI VoIP gateway offers superior voice technology as well as
state-of-the-art end-users features such as T.38 fax relay and G.168-2002 compliant Echo
Cancellation. In addition, low bit-rate (LBR) voice coders are supported, saving valuable
bandwidth.
The MediaPack complies with leading VoIP standards and is designed and tested to be
fully interoperable with leading softswitches and SIP servers. The MediaPack supports
Session Initiation Protocol (SIP) and H.323 protocols, enabling the deployment of VoIP
solutions in environments where each enterprise or residential location is provided with a
simple media gateway.
The MediaPack gateway spans a range of up to four BRI S/T interface ports (RJ-45) for
connection to an enterprise PBX (FXO), ISDN phones, fax machines, and computers. The
ports can be configured for network (NT) or terminal equipment (TE) side for interfacing
with ISDN (CO) or PBX.
Each BRI S/T port supports up to two voice/data channels (i.e., two B-channels) and one
signaling channel (i.e. D-channel). Thus, the MediaPack supports up to eight simultaneous
VoIP channels. In addition, the gateway can support up to 32 TE devices (e.g., ISDN
telephones) when implementing an S/T bus (8 devices per BRI S/T port).
In addition to the four BRI channels, the MediaPack provides a fifth BRI interface for
supporting lifeline telephony services in the event of a power outage. This lifeline BRI
interface supports an ISDN connection to the ISDN/PSTN network (instead of the IP
network), and can connect at least one ISDN phone to the ISDN network.
The MediaPack supports ISDN fallback in case of power failure or network deterioration. In
such a scenario, the ISDN port is switched to the redundant port, which is connected to the
ISDN network (i.e., PSTN).
The MediaPack provides two 10/100 Base-TX Ethernet ports for interfacing with the Local
Area Network (LAN) and Wide Area Network (WAN). In addition, the MediaPack provides
integrated router capabilities such as NAT, DHCP Server and Client and a PPPoE client for
the Ethernet interfaces.
The MediaPack gateway is a compact device that can be mounted on desktop, wall, or in a
standard 19-inch rack using shelf racks.
The MediaPack gateway offers remote management and configuration by providing an
Embedded Web Server. This user-friendly Web interface can be accessed by using
standard Web browsers (Microsoft™ Internet Explorer or Firefox).
