7.2 Linking Eclipse HX-Pico matrix frames with the
PiCo-Link
You can create one non-blocking 64 port Eclipse HX system by connecting two Eclipse HX-
PiCo matrix frames together, using the PiCo-Link RJ-45 connectors on the matrices.
This type of connection gives each connected matrix access to all of the audio ports of both
matrices without using up ports for trunk lines (although logical routing such as IFBs,
Telephone handling and ISOs cannot be used across the frames).
To make this connection, use a specially constructed screened CAT5 cable of maximum
length 1 meter (3.28 feet). The cable is wired as shown in Table 21: HX-PiCo pinout for
base loop linking.

Note:
Hopping is not supported. DTMF generaton and detection is only supported on 16 ports
(ports 17 – 32) on each Eclipse HX-PiCo.The last four ports on an Eclipse HX-PiCo matrix
frame are four-wire ports, and not available for panel connections.
