7.3.1
IOM
Control Information for (De-)Activation Downstream
ARD
1 0 - -
Activation Request Downstream. The upstream unit of the IOM
interface is a layer 1 device which has just finished synchronizing. Or,
it is a layer 2 device (which doesn
’
t synchronize of course) initiating
activation. Receiving this, the NTC-T AM with IEC-T functionality
selected (LT mode in the exchange) starts by sending awake signal
INFO U2W. After a successful awake procedure, the NTC-T AM with
IEC-T functionality selected sends INFO U2. In the deactivated state,
the NTC-T AM with IEC-T functionality selected in LT-RP mode starts
the same procedure on this command. But, usually the LT-RP is
activated with RSYD and the awake procedure has already been
done when it gets an ARD command. Then, the NTC-T AM with IEC-
T functionality selected changes from sending INFO U2A to INFO U4
which means that the applied INFO U2 from the exchange is
transparently handed over.
ARD represents the following group of activation requests:
ARN 1000 Activation Request no loop.
ARL 1001 Activation Request local loop only in the exchange.
AR2 1010 Activation Request loop 2 in the exchange or local loop in
the repeater and the NT.
AR4 1011 Activation Request loop 4 only in the exchange.
For the description of the loops see
Chapter 6.7
.
Activation Indication Downstream. The upstream unit of the IOM
interface (usually a layer 1 device) has detected the line signal which
enables the transparent state of the transmission line (INFO U4H on
the Uk0 interface). If the layer 2 device in the exchange sends out this
code, it has no effect on the NTC-T AM with IEC-T functionality
selected.
AID
1 1 - 0
AID represents the following group of activation indications:
AlN 1100 Activation Indication with no loop.
AlL 1110 Activation Indication with local loop.
For the description of the loops see
Chapter 6.7
.
Deactivation Request. The upstream unit of the IOM
Interface
requests deactivation. This command must be applied at least 0.5 ms
to ensure that the downstream unit has reached the requested state,
after the information on the C/I channel has been evaluated.
