1.4.4 IDU-1D1V and IDU-1D2V Voice Gateways
The SIP Voice Gateways IDUs enable operators and service providers to offer end
users a combination of IP-telephony and broadband data services, enabling
uninterrupted operation od the CPE during power outages. The IDU-1D1V and
IDU-1D2V provide the same features and capabilities as the SIP versions of the
VG-1D1V and VG-1D2V described above, with the additional capability to serve as
IDUs of the PRO-S CPE, including a backup battery to ensure uninterrupted
services during power outages of up to two hours.
The Voice Gateway IDU are powered from the mains and connects to the ODU via
a Category 5E Ethernet cable. This cable carries the Ethernet data between the
two units as well as power (54 VDC) and control signals to the ODU. It also carries
status indications from the ODU. The Voice Gateway IDUs are available with
either RJ-11 or Terminal Board telephone connection(s).
1.4.5 SRU Service Residential Unit
The Service Residencial Unit (SRU) offers users of the Self Install Si CPE
uninterrupted voice connections, integrating voice and data services into a single
unit. The SRU acts as a bridge between the Si CPE and the subscriber’s LAN, and
has two POTS lines that support analog telephones, faxes and modems with a SIP
based VoIP service, operating with common available SIP servers, proxies and soft
switches.
The SRU is powered from the mains, providing power also to the Si CPE, and has
backup batteries that ensure uninterrupted service during power outages for at
least 2 hours with 10% voice calls.
