The transition criteria used by the IPAC are described in the following sections. They are
grouped into:
– C/I commands
– Pin states
– Events related to the S/T-interface
C/I Commands
AR8
AR10
ARL
DI
RES
TIM
TM1
TM2
Semiconductor Group
Activation Request with priority 8 for D-channel transmission. This command
is used to start a TE initiated activation. D-channel priority 8 is the highest
priority. It should be used to request signaling information transfer.
Activation request with priority 10 for D-channel transmission. This command
is used to start a TE initiated activation. D-channel priority 10 is the lower
priority. It should be used to request packet data transfer.
Activation request loop. The IPAC is requested to operate an analog loop-
back close to the S/T-interface. ARL is an unconditional command.
Deactivation indication. This command transfers the IPAC into “F3 power
down” mode and disables the IOM-2 clocks.
Reset of state machine. Transmission of Info 0. No reaction to incoming infos.
RES is an unconditional command.
Timing Request. Requests the IPAC to change into power-up state and
provide timing signals on IOM-2.
Test Mode 1. Transmission of single pulses on the S/T-interface. The pulses
are transmitted with alternating polarity at a frequency of 2 kHz. TM1 is an
unconditional command.
Test Mode 2. Transmission of continuous pulses on the S/T-interface. The
pulses are sent with alternating polarity at a rate of 96 kHz. TM2 is an
unconditional command.
