Functional Description
The DMG1000 Gateways each contain eight digital
PBX emulation interfaces and a 10/100 BaseT Ethernet
connection for connecting to a LAN. An analog loop
start unit designed for voice mail and unified messaging
applications is also available to connect to PBXs that
do not have an appropriate digital interface. The analog
loop start unit supports integration via in-band signaling
(DTMF or FSK) or serial protocols (SMDI, MCI, and
MD-110).
The DMG1000 Gateways provide a simple, cost-
effective transition to voice and data convergence for
enterprises with PBXs. Connected externally, they offer
an IP solution that works with current legacy equipment.
They support SIP-based applications as well as T.38 for
fax transmissions over IP (FoIP).
Gateway unit features include:
•Voice over Internet Protocol (VoIP) – Supports SIP per
RFC 3261. Uses Real-time Transport Protocol/Real-
Time Control Protocol (RTP/RTCP) for delivery of
voice over the LAN or WAN
•IP security — Supports TLS for SIP messages, SRTP
for media stream, and HTTPS for web interface
•Enhanced voice processing – Supports a variety of
compression algorithms, including G.711 A-law and
µ-law, G.723.1, and G.729AB
•T.38 Fax over Internet Protocol (FoIP) – Emulation
units transcode fax from T.30 fax protocol, supporting
V.17, V.21, V.27, and V.29 modulation schemes, to
T.38 for transmission over a packet network
•Hot swap – Allows gateway units to be added or
removed without affecting other gateway units
•Web server interface – Each gateway unit is delivered
with a web server interface, allowing configuration and
software upgrades via a web browser
Congurations
The DMG1000 Gateways can be used to connect IP
telephones to a legacy PBX, integrate network-hosted
applications with the PBX, extend the PBX to branch
offices, and integrate various voice and call processing
capabilities in an enterprise LAN or WAN environment.
Using exclusive PBX network interfaces (emulating),
these media gateway appliances provide exceptional IP to
PBX integration capabilities to protect an investment in
legacy telecom equipment.
Figures 1 and 2 provide sample configurations.

Call Routing
The DMG1000 Gateways route calls from the switched network to a VoIP destination on the IP network. Conversely, it
routes calls from the IP network through a switch port to a destination telephone number on the switched network. The
DMG1000 Gateways support the following call routing options:
•User-configurable list of VoIP servers
•IP load balancing
•IP fault tolerance
•TDM-to-TDM
