S-134 Short Text Messaging Service (STM Service)

General Description

This feature enables a short text message (STM), once arrived at a mail box of the Short Text Message Server (external equipment), to be automatically distributed to the addressee PS via Open Application Interface (OAI).This feature also provides a Zip Tone and “TM WAITING” notification on the display (LCD) of the address PS that is busy, and if the PS is out of zone, the feature makes retransmission of the STM after the PS returns to the zone.

Note: This describes STM Facilities available for external STM OAI application. Actual functionality depends on the application.

Operating Procedure

1.By using PS function key, users can set a password (four digits or less) to the PS to enter STM (short text message system) mode.

2.The STM transmitted to the PS while PS’s buffer (maximum ten messages) is busy is temporarily kept in STM server. When requesting the STM, delete old STM data in the buffer using the function key. Then the PS automatically requests STM server to retransmit the STM.

Service Conditions

1.This feature is available only for My Line (L1) of a two-line Dterm PS (not provided for Sub Line (L2)).

2.This feature is provided in the same form as that for call termination.

3. STM message transmission route is only one way: STM server → PS

4.An STM can contain 128 byte data in the maximum.

5.The following are not available in this feature.

•Call Forwarding - All Calls

•Call Forwarding - Don’t Answer

•Call Forwarding - Busy Line

•Call Forwarding PS Incoming Call Incomplete

6.This feature is counted as ZT peg count.

7.If the following occur, STM is not distributed, but stays in the mail box of the STM server. The STM is safely transmitted later by this feature’s retransmission function.

•Addressee PS is out of zone.

•Addressee PS has a power down.

•The line of addressee PS is busy.

•PS is in a state of hand-over. Note

Note: When hand-over unexpectedly starts while the message transmission is partially in progress, this feature sees this as a squelch disconnection and performs message retransmission after the hand-over is completed.

8.Wireless Roaming is not available in this feature.

9.More than STM server cannot be transmitted to a single PS simultaneously. Only the earliest STM can be sent safely.
