Layer 1 Status
The ITU-T I.430 recommendation (the basic user-network inter face - Layer 1 specification) specifies layer 1 activation/deactivation procedures.
Before understanding the procedures, the status and INFO signals should be noted.
TE (Terminal Equipment) Status
StatusDescription
F1TE is turned off.
F2TE is turned on, but no signal is exchanged.
F3TE is stopped. No signal is exchanged between TE and NT.
F4TE is waiting for the response to the INFO1 signal from NT.
F5TE is checking if the signal from the NT is INFO2 or INFO4.
F6TE is waiting for signals from NT after receiving the INFO2 signal.
F7TE and NT are synchronized.
F8TE has failed to synchronize with NT, and is waiting for the stop request from NT
NT (Network Termination) Status
StatusDescription
G1NT has stopped.
G2NT is sending INFO2.
G3TE and NT are synchronized.
G4NT is terminating itself.
INFO Signals
NT to TE DirectionTE to NT Direction
INFO0No signalINFO0No signal
INFO2
INFO4Synchronized frameINFO3Synchronized frame
Activation signal in
synchronized condition
INFO1
Activation signal in nonsynchronized condition
Activation Procedure from the TE
In idle “F3” status , the TE sends the INFO1
signal to the NT and changes to “F4” status.
The NT then changes to “G2” status and
sends the INFO2 signal to the TE.
The TE changes to “F5” status and stops
sending signals to synchronize itself to the
signal from the NT.
After the TE has synchronized to the signal,
it sends the INF O3 signal to the NT and
changes to the “F6” status.
The NT then changes to “G3” status and
sends the INFO4 si gnal back to the TE to inform that a physic al lin k ha s be en est ablished.
The timers T1, T2 and T3 are used to reset
the TE or NT if a correct response has not
been received before the timers expire.

Activation Procedure from the NT
The procedure starts from the NT by sending the INFO2 signal to the TE.
After the TE has synchronized to the signal,
it sends the INF O3 signal to the NT and
changes to the “F6” status.
The NT then changes to “G3” status and
sends the INFO4 si gnal back to the TE to inform that a physic al lin k ha s be en est ablished.
The timers T1 and T2 are used to reset the
NT if a correct response ha s no t be en received before the ti me rs ex pi re.
Termination Procedure from the NT
The terminatio n pro ce du r e st art s fro m sy nchronized status (“F7” status for the TE and
“G3” status for the NT).
To terminate the physical connection, the NT
just stops sending signals and ch an ge s to
“G1” status. (The INFO0 signal means no signal is sent from the NT.) Then, the TE also
stops sending signals and changes to “F3”
status.

TEI management procedure
•
The TEI management procedure includes the following procedures:
. TEI assignment procedure
. TEI check procedure
. TEI clear procedure
. TEI identifying procedure executed by the user as an option
Conceptually, these procedures belong to the layer management entity.
The network side layer management entity is referred to as Assignment Source Point
(ASP). The TEI management procedure is performed by using the data link layer of a
non-confirming type information transfer.
SAPI is set to 63, and TEI is set to 127.
The following shows the format of the me ss ag es tr an sf erre d between layer management entities:

Table 24. Fixed Shift Procedure (96) [Extension of Code Group]
The following two code group shift procedures are available:
•
1. Fixed shift procedure
2. Temporary shift procedure
1. Fixed shift procedure
The fixed shift procedure is us ed to indicate the code group newly selected. Once
specified, the code group is maintained until a fixed shift information element which
specifies the use of another code group appears.
For the charge information notification service, "charge notification" information is
sent by code group 6 using this procedure.

111: Code group 7: Information

2. Temporary shift procedure
The temporary shift procedure is used when temporarily shi fting to a certain code
group. In the temporary shift procedure, a single-fixed-length information element is
used to identify the code group of the information element which follows it. After analyzing the latter information element, the code group which was used before the temporary shift procedure was executed will again be used for analyzing the next
information element.

If two different codes are used for a PGI/PI, eg. document content attribute on page VIII-19,if the first code is used, this will be referred to as case a. Also, if the
second code is used, this will be referred to as case b.
1: In case a, Net ID is stored at ♦1 (that is, the same value as at ♦3 is stored).
♦
2: In case a, polling ID (Net ID or File ID) is stored at ♦2 (that is, the value at ♦4 determines the Net ID).
