System Outline 1-21
■ ELCOT Card (KX-TD50180)
Functions
Enhanced Loop Start Central Office Trunk card (8 CO Lines/ card)
(1) Loop start CO interface.
CPC detection, 1 DTMF generator. Line Reversal detection.
With loop start, you seize a line by bridging through a
resistance the tip and ring (both wires) of your telephon
line.
(2) Caller ID/Pay Tone Capability
Two Caller ID Cards (KX-TD193) can be mounted on
ELCOT Card.
or
Two Pay Tone Cards (KX-TD50189) can be mounted on
ELCOT Card.
(3) Power failure transfer (PFT) by each port.
Tip/Ring of CO are connected to a CO interface circuit,
and directly to ELCOT PFT modular. When power failure
occurs, CO Tip/ring leads are directly connected to SLT
Tip/Ring leads, but ELCOT PFT modular and SLT PFT
modular should be connected to each other in advance.
(4) Diagnostic transfer (DT) by each port.
A diagnostic relay is placed in Tip/Ring of each port.
During diagnostic test, only one diagnostic relay in an
ELCOT of a system is activated.
Operation The LED indicator on the ELCOT card lights when the sys-
tem resets or ELCOT local reset occurs.
■ BRI Card (KX-TD50288)
Functions ISDN Basic Rate Access Interface. (8 circuits/card)
(1) 8 ISDN Basic Interface (2B+D)
(2) S0/EXT flexibility for each line
(3) Power Feeding of EXT mode
One card total : 18 W max.
One Line : 4.5 W max.
(4) Line cording : AMI
(5) Impedance : 100 ohms
Operation LED indicator on BRI card lights when the system reset, BRI
card local reset or BRI card fault occurs.
