INCA-D
PSB 21473
Line Transceiver
Power-Up
The line interface is deactivated (info 0 on the line) and the clocks are running.
Pending Activation
Upon the command Activation Request (AR) the INCA-D transmits the 2-kHz info 1w
towards the network, waiting for info 2.
Level Detect (Resynchronisation)
During the first period of receiving info 2 or under severe disturbances on the line the
receiver recognizes the receipt of a signal but is not (yet) synchronized.
Synchronized
The receiver is synchronized and detects info 2. It continues the activation procedure by
transmission of info 1.
Activated
The receiver is synchronized and detects info 4. It concludes the activation procedure by
transmission of info 3. All user channels are now conveyed transparently.
Analog Loop 3 Pending
Upon the C/l-command Activation Request Loop (ARL) the INCA-D loops back the
transmitter to the receiver and activates by transmission of info 1. The receiver is not yet
synchronized.
Analog Loop 3 Synchronized
After synchronization the transmitter continues by transmitting info 3.
Analog Loop 3 Activated
After recognition of the looped back info 3 the channels are looped back transparently.
Test Mode i
Test mode initiated by SCP-, SSP-commands.
Reset state
A C/I command reset (RES) forces the INCA-D to an idle state where INFO 0 is
transmitted. Thus activation from the NT is not possible. Clocks are still supplied.
