9.8.12	Daylight saving time/DISA

Settings | System Parameters | Daylight saving time/DISA

The date and time for the switchover to Daylight saving time can be defined in this dialog. The day and month when daylight saving time begins and ends is defined for each year. The communication system switchover occurs between 02.00 am and 03.00 am in both cases.

External features for the communication system can be activated from an external telephone via DISA (Direct Inward System Access). This proves to be useful whenever external stations want to access features, such as call forwarding. Furthermore, with DISA, it is possible to make an outgoing external connection via the incoming external connection.

9.8.12.1

Area: Set daylight saving time dates

Starting Year

The communication system allows you to define the switchover date for a ten-year period. The starting year determines when this period begins.

If there is no daylight saving time in your country and the current year was set as the starting year, the communications system miscalculates the time. To solve this problem enter a starting year that does not match the current year and is in the distant future, e. g. 2050.

Start, End, Year columns

The table contains the corresponding start (last Sunday in March; in the US first Sunday in April) and end information (last Sunday in October) for the years 1990 through to 2079.

The start information usually entered to this table (last Sunday in March) does not apply to the US. The start date must be set to the first Sunday in April in this case. Otherwise the switchover to daylight saving time in the communication system will be implemented a week early.

9.8.12.2

Area: Remote use of services, DISA

In PRI and BRI, a station number is assigned to this feature via the DID Number field.

PRI environments work with a communication system with a primary rate connection via TMS2M/TS2. BRI environments work with a communication system with a basic rate connection realized via STMD/STLS.

In the USA, this is not relevant to BRI.

DISA, DID no.

DISA is dialed with a DID number (DID No.) or via call assignment (MSI).

In order to be able to use the DISA functions, the user must enter a password. With the Security mode options, one can establish whether the user must wait after entering the password or whether he/she must enter the hash symbol (#).

With Mobility Entry: The authentication via password is not required if a call recognized as a mobility number is made externally to a DISA DID number.In this case the internal dial tone is directly connected. The terminal of the external station must transmit it´s number.This number is then checked against the mobility entry list.

The feature DISA is not supported by HiPath 5000

CAID (only for USA)

Subscribers can receive multiple calls for the same call number via multiple ISDN lines by using the line identifier (CAID = Call Appearance Identifier) assigned to that call number. With this feature, the Central Office (CO) can offer a call at multiple interfaces, since the Call Appearances for call numbers can be shared. This enables HiPath 3000 to accept the call at an unused interface.

CAID values can be set for the CO type AT&T or EWSD. These values consist of one or two digits, which are assigned by the CO to the primary and secondary system numbers. A CAID value represents a connection path between a voice subscriber or a data terminal and a BRI channel. For each extension, at least one line ID (CAID) must be programmed so that external calls can be initiated or received there without any intervention from the Attendant.

Each station can be assigned a maximum of four CAID numbers.

In order to allow an extension to use external phone functions, e.g., to accept call waiting or conference calls, it must be assigned multiple line IDs. This CAID enables various answering machine functions to be simulated at a single extension. In other words, each of the CAID numbers simulates an additional extension (i.e., a line) without an actual external line being present for these additional extension numbers.

Some COs do not assign any CAID to the ISDN data terminals. If you do not know whether CAID numbers were assigned to the system, please contact your BRI provider.

Security mode

Log-on to the communications system occurs via a password. This password consists of the internal station number and the lock code password. The password entry is only acknowledged after a timeout or after the end-of-input symbol # is detected. The acknowledgement procedure After timeout or After input # can be selected here.

DISA internal

The DISA in a HiPath 5000 RSM/AllServe environment (Direct Inward System Access Internal) feature allows easy activation and implementation of specific features in another node. This DISA procedure can only be used within a networked system and serves to activate and execute some features in another node. Please note, however, that before the DISA procedure can be used, this must be activated by entering the service code DISA internal (*47). To activate this feature, each node has a unique DISA call number throughout the system. DISA internal does not support trunk seizure. Authorization levels are not checked when DISA internal is implemented.

DISA internal, DID no.

After entering the DISA internal procedure (*47), features are activated via a unique DISA call number (DID no.) + DISA station + password for the feature to be activated + optional suffix.

Example on how to activate the LM's DISA internal feature:

1.	Activate the DISA internal procedure via the service code *47

2.	Enter the DISA call numner (DID no.) of the appropriate node, e.g., 7777

3.	Enter the appropriate station at which the service/feature is to be executed, e.g., 100

4.	Enter the password for the service/feature to be activated, e.g., *1 (for call forwarding)

5.	Enter a suffix if required, e.g., 1 (for all calls)

Mobility Callback, DID no.(from HiPath 3000/5000 V8, HiPath OpenOffice EE V1 R2)

"Mobility Callback" is used together with the "Mobility Entry" feature, see Section 9.2.8 "Mobility Entry (not for USA)". The "Mobility Callback" feature can be used for home office jobs.

If a teleworker calls a special DID number from their private telephone, the call is then automatically terminated before the connection is established and a callback is immediately.

The requirements are:

•	The external number of the calling telephone is registered and configured on the communications system.

•	The DID number is configured.

•	Together with the call, the CLIP information, i. e. the external number is transmitted.

After the callback no further authorization is necessary. Via the communications system, the teleworker can make internal and external calls as well as use all mobility features.

If the number is not registered on the communications system, the call is terminated and no callback is made.
