CTEL4 – Analog Telephony Card

The CTEL4 card is Type 2 hardware.

Type 2 hardware provides new cables and connectors between the I/O cards and main boards in Cores and I/O Frames. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label on the back of the Core and I/O Frame, and the bottom of the I/O cards.

Due to electrical current limitations imposed on telephony devices, there is a limit to the number of CTEL4 cards that can be installed in Q-SYS host hardware.

Host Hardware	Available I/O Slots	Max CTEL4 Cards Allowed
Q-SYS Core 510 Series	8	3
Q-SYS I/O Frame	4	3
Q-SYS Core 3100, Core 1100	1	1
Q-SYS Core 500i	8	1
Q-SYS Core 250i	8	1
Q-SYS I/O Frame 8s	8	1

Note: The CTEL4 card limits do not affect other Q-SYS I/O cards. All other Q-SYS I/O cards (in any combination) may be installed into a host product alongside the supported CTEL4 maximums.
