TCO (Art.No.: VOXORXR0034/2U) is available as an optional factory installed add-on for Xorcom XR2000, XR3000 units with eight or more FXS ports.
Astribank with Telco Connector Option (rear panel)
To streamline installation of multi-port systems, the TCO unites all FXS ports on the Astribank unit into a single telecom connector on the real panel.
TCO cable with 32 color-coded twisted pairs
A special telecom cable with 32 color-coded twisted pairs (supplied as part of the option) routes the 32 ports to the building telephony wiring Crone. The Telco port is connected in parallel to the front panel FXS ports, and does not disable it - so the front panel RJ11 connectors can be use in parallel with the Telco port for maintenance or other purposes. In addition, the indication lights are active when the Telco port is in use.
