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

Status Description

F1 TE is turned off. F2 TE is turned on, but no signal is exchanged. F3 TE is stopped. No signal is exchanged between TE and NT. F4 TE is waiting for the response to the INFO1 signal from NT. F5 TE is checking if the signal from the NT is INFO2 or INFO4. F6 TE is waiting for signals from NT after receiving the INFO2 signal. F7 TE and NT are synchronized. F8 TE has failed to synchronize with NT, and is waiting for the stop request from NT

NT (Network Termination) Status

Status Description

G1 NT has stopped. G2 NT is sending INFO2. G3 TE and NT are synchronized. G4 NT is terminating itself.

INFO Signals

NT to TE Direction TE to NT Direction

INFO0 No signal INFO0 No signal INFO2 INFO4 Synchronized frame INFO3 Synchronized 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.

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.

*1 to *4 are employed from K200I. From K200I ♦1 is used as File ID, and ♦2 as General Net ID. 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).

♦

3: In case b, Net ID is stored at ♦3 ( ♦1 is unused).
