LT-T Mode (Unconditional States)
The unconditional states should be left with the command TIM.
• Test mode 1
• Test mode 2
• Reset state
Restriction in LT-T Mode
The two first TRANSIU Channels out of 24, (i.e. Channel_0 and channel_1 in the IOM-
2000 frame, referring to VIP_0, ch_0 and ch_1) do not work in LT-T mode.
In order to have an optimized usage of the LT-channels it is recommended to
proceed as follows:
• If only one VIP is used, 8 channels can be applied in LT-T mode by using a DCL_2000
• If 2 VIPs are used, up to 16 channels can be applied in LT-T mode by using a
• If 3 VIPs are used up to 22 channels (channel 2..23) may be applied in LT-T mode by
Data Sheet
Single alternating pulses are sent on the T interface (2 kHz repetition rate).
Continuous alternating pulses are sent on the T interface (120 kHz).
A hardware or software reset (RES) forces the line interface to an idle state where the
analog components are disabled (transmission of INFO 0) and the T line awake
detector is inactive.
