4.2.1.3.
Interrupt
Note:
• nHALT signal is consistent with the existing PBX and performs polling by I/O port.
However, when the CPU (IC1) goes to Sleep Mode at HALT, the CPU (IC1) is enabled for interruption on release nHALT and
return from Sleep Mode.
• The nIRQ[0] interrupt of ASIC (IC2) is set to output and the interrupt output is to the CPU (IC1) (Mainly, DPRAM communication
interrupts).
• The LOS signal of the T1-IC (IC302) is a level output which goes "H level" at the line reference lost. Thus, 
↓ edge interruption is
available at the line reference lost by inputting the inversion signal of the LOS to the CPU (IC1). The polling operation is also pos-
sible by setting the nIRQ4 terminal of the CPU (IC1) to i/o port. 
(The configuration with the interruption processing is to give a consistency with the existing PBX.)
• Since the nRxMF signal of the T1-IC (IC302) occurs in periodic frame timing, the polling by i/o port is impossible.

Line Interface Function
4.3.1.
Line Interface Outline
E1 card uses the E1-IC (IC302)(Mitel) as the IC for the line interface.
Also, see the E1-IC (IC302) Data Sheet for the detailed specifications.
4.3.2.
Line Interface Loopback
This card has a relay for loopback test on the primary side of the line to cut and divide into the line failure or the PBX's own fail-
ure, when there is a defect in operation.
