ESCRIPTION
The IAD(8)-U( ) ETU is an optional interface package for Electra Elite IPK KTS that
can combine trunk and tie line calls into SIP trunks. This ETU can be assigned as a
2-port TLI(2)-U10, 4-port DID (4)-U10, 4-port or 8-port DTI-U10 ETU, COI/
COID(4)-U10, 8-port COI/COID(8)-U10 or DTI(4)/DTI(8) ETU.
The onboard 10/100 base T-connector provides WAN/LAN connectivity. The NEC
IAD ETU contains a regular TCP/RTP/IP stack that can handle real time media,
supports industry standard SIP communication on the WAN side, and interfaces with
the Electra Elite IPK as a regular interface board. The IAD card, from the network
administration perspective, is an end-point on the IP network. For the Electra Elite
IPK system technician, it is just like any other trunk interface (depending on the
operating mode described in
Chapter 4 IPK IAD(8)-U( ) Configuration ).
