8-port analogue trunk daughter card with Caller ID. Caller ID signal type FSK/FSK (with Call Waiting Caller ID [Visual Caller
ID])/DTMF compatible. To be mounted on the CLCOT8 card.

Accessory (included): Screws x 3

An amphenol 57JE type connector is used on some of the optional service cards.
To connect an Amphenol connector, use the spring latch or screw to fix the upper part and use Velcro   tape to fix the lower part
of the connector.

When the power supply to the PBX fails, power failure transfer (PFT) will switch from the current connection to the Power Fail-
ure Connection. Refer to "Power Failure Transfer" in the Feature Guide for further information.
Note:

While DC power is provided by the backup batteries, the PBX will remain fully operational and the connection will not switch
to the Power Failure Connection.

Power Failure Connection connects a specific SLT and a trunk in the event of power failure. The following analogue trunk
and extension cards can be used for Power Failure Connections:

• Analog trunk cards: LCOT16 (4 PFT ports), LCOT8 (2 PFT ports), LCOT4 (2 PFT ports), and CLCOT8 (2 PFT ports)
• Extension cards: MCSLC24 (2 PFT ports) and MCSLC16 (2 PFT ports)

To 1 analogue trunk card, connect only 1 extension card.

By programming the PBX, a trunk conversation established during power failure can be maintained even when the power
returns and the connection is switched back to the normal configuration from the Power Failure Connection. However, if no
special programming is performed, the connection will be dropped when power returns.

Accessory (included): none
User-supplied (not included): RJ11 connectors
