Trunk Interface Cards
Trunk interface cards interface the system universal ports to the individual
outside trunks. Four types of cards are available to meet various outside
communication requirements.
IX-8UNTK-1 Universal Analog Trunk Card
The IX-8UNTK-1 card is an analog trunk card that was developed for
improving the speech quality of IP phones over analog trunks. This card
employs a linear CODEC and a DSP-based echo canceller. The IX-8UNTK-1
card is equipped with eight circuits for analog trunks and Caller ID. Each of
the eight trunks can be set as Loop Start or Ground Start as required. This card
is UL approved for the IX-CME, IX-EXPME1, and IX-EXPME2 ECS
expansion cabinets only.
