IDU-1D2V: A SIP Voice Gateway with battery backup that serves also as an
IDU for the PRO-S CPE, supporting 1 data port and 2 POTS ports. Available
with either RJ-11 or Terminal Board telephone connections.
These Gateways incorporate an advanced protocol (DRAP) for automatic
registration and allocation of wireless link resource.
In addition, the optional Service Residencial Unit (SRU) acts as a bridge between
the Si CPE and the subscriber’s LAN, with two POTS ports providing SIP based
VoIP services and a battery backup for both the SRU and the Si CPE.
Details on installing, managing and using the Voice Gateways, the Wireless
Networking Gateway and the SRU are provided separately in the relevant
manuals.
1.4.1 DRAP (Dynamic Resources Allocation
Protocol)
DRAP is a protocol based on IP/UDP between the Gateway (installed behind the
SU) and the BreezeMAX system. The protocol provides an auto-discovery
mechanism for the Gateway, so no specific configuration is required and the
Gateway can automatically locate and register with the BreezeMAX base station.
The protocol uses a few simple messages enabling a Voice Gateway to request
resources when calls are made, and the BreezeMAX to dynamically allocate them.
