Clear-Com HX System Frames - Manual (Page 26)

4.4.1 DTMF generation and detection
DTMF generaton and detection is only supported on 16 ports (ports 17 – 32) on the
Eclipse HX-PiCo. When using a TEL-14 interface module with the Eclipse HX-PiCo, Clear-Com
recommends that the TEL-14 is connected to one of these matrix ports for full functionality.
Although ports 1 - 16 are not DTMF-enabled, a TEL-14 interface module connected to one of
these ports can receive incoming calls. However, it is not possible to then use inward DTMF on
ports 1 though 16. It is also not possible to dial out from the matrix on these ports.
A shielded cable should be used.
4.5 Wiring schemes
The Eclipse HX-PiCo uses:
• A 4-pair (analog) wiring scheme between the matrix and user panels (V-Series and
I-Series user panels).
• A 2-pair (analog) wiring scheme between the matrix and four-wire equipment / devices.
• Single-pair wiring for digital connections.
Eclipse HX user panels (V-Series and i-Series user panels) have built-in RJ-45 connectors.
4.5.1 4-Pair analog
4-pair analog connections are performed using shielded CAT-5 RJ-45 cable:
Pair Description
Pair 1 Transmits analog audio from the matrix to the panel.
Pair 2 Transmits digital data from the panel back to the matrix.
Pair 3 Transmits audio from the panel to the matrix.
Pair 4 Transmits digital data from the matrix back to the panel.
