Clear-Com HX System Frames - Manual (Page 75)

Tip: The matrices are configured for linking using EHX. For more information, see your
EHX documentation (including EHX Help).
7.3 Tie-line (audio only) linking
You can directly connect two Eclipse HX matrix frames through tie-line linking. The tie lines
between the matrices are wired as in Figure 27: Dedicated serial port audio trunk wiring.
By configuring each of the linked ports in each system as a partyline, the two systems can
talk and listen to anyone on that partyline in either system. Call signals will also pass from
one system to the other.
However, since no control data passes between the matrices, assignments cannot be
dynamically allocated among the ports of a matrix. Only the one partyline on the first matrix
connects to the partyline of the second matrix.
7.4 E1 / T1 linking
The E-QUE interface card, which can be fitted to the Eclipse HX-Omega, Eclipse HX-Median
and Eclipse HX-Delta matrix frames, can be used to provide:
• Direct E1 to E1 port connections.
• Trunk linking, using a network between systems.
• T1 trunking between Eclipse HX systems, and between Eclipse HX systems and
compatible third-party equipment.
Tip: You can also use the E-QUE card for E & M signaling. For more information, see
6.8 E & M signalling with an E-QUE E1 / T1 interface card.
For more information about the E-QUE interface card, and other Clear-Com interface cards,
