Direct Inward System Access (DISA)

Description

DISA permits outside callers to directly dial system extensions, trunks and selected features. This could help an employee away from the office that wants to directly dial co-workers or use the company’s trunks for long distance calls. To use DISA, the employee:

•

Dials the telephone number that rings the DISA trunk

•

Waits for the DISA trunk to automatically answer with a unique dial tone

•

Dials the 6-digit DISA password (access code)

•

Waits for a second unique dial tone

•

Accesses a system trunk, uses a selected feature or dials a system extension

DISA calls ring system extensions like other outside calls. If an extension has a line key for the DISA trunk, the call rings that key. If the extension does not have a line key, the call rings a CALL key.

You can set DISA operation differently for each Night Service mode. For example, a trunk can be a normal trunk during the day and a DISA trunk at night. You can also set the routing for DISA trunks when the caller dials a busy or unanswered extension, dials incorrectly or forgets to dial.

DISA Class of Service

DISA Class of Service provides features and Dialling restrictions for DISA callers. This allows you to control the capabilities of the DISA callers Dialling into your system. When a DISA caller first accesses the system, they must enter a DISA password before proceeding. The system associates the password entered with a specific user number, which in turn has a Class of Service. If the Class of Service allows the action (such as making outgoing trunk calls), the call goes through. If the DISA Class of Service doesn’t allow the action, the system prevents the call. The DISA Class of Service options are:

•

Trunk Group Routing/ARS Access

When a DISA caller dials into the system, they may be able to dial 0 and place outside calls. Any toll charges are incurred by the system. The call follows the system’s Trunk Group Access or

Automatic Route Selection - whichever is enabled.

•

Trunk Group Access

DISA callers may be able to access a specific trunk group for outgoing calls through the system.

To access a Trunk Group, the user dials Service Code 804 followed by the Trunk Group number

(e.g., 01). This allows the DISA caller to place an outgoing call over the selected group. Trunk

Group Access bypasses the system’s Trunk Group Routing/ARS/Trunk Access Maps. As with dial 0 access, any toll charges are incurred by the system. Also see Direct Trunk Access below.

•

Common Abbreviated Dialling

The system’s Common Abbreviated Dialling bins may be available to DISA callers. This could save the DISA caller time when Dialling.

•

Operator Calling

A DISA caller may be able to dial 9 for the system’s operator.

•

Paging

Internal and External Paging may be available to DISA callers. This allows co-workers in adjacent facilities, for example, to broadcast announcements to each other.

•

Direct Trunk Access

DISA callers may be able to select a specific trunk for outgoing calls through the system. To directly access a trunk, the user dials Service Code 805 followed by the trunk’s number (e.g., 01).

This allows the DISA caller to place an outgoing call over the selected trunk. Direct Trunk

Access bypasses the system’s Trunk Group Routing/ARS/Trunk Access Maps. As with dial 0 access, any toll charges are incurred by the system. Also see Trunk Group Access above.

Features

•

DISA Trunk Barge In

The DISA Trunk Barge In option allows a caller to break into another extension’s established call. This sets up a three-way conversation between the intruding party and the two parties on the initial call.

DISA Toll Restriction

The digits a DISA caller dials for an outgoing call may be subject to the system’s Toll Restriction.

DISA Operating Modes

The DISA Operating Modes determine what happens when a DISA caller forgets to dial, calls a busy or unanswered extension or dials incorrectly. The system can either drop the call or send it to a preset Ring Group

(called a DISA Transfer Destination).

Department Calling with Overflow Message

If a DISA caller dials a busy Department Calling Group, the system can periodically play the voice prompt,

“Please hold on. All lines are busy. Your call will be answered when a line becomes free.” while the caller waits.

The interval between the voice prompts is the DISA Overflow Message Time. When an extension in the

Department Group becomes available, the call automatically goes through. If the Department Calling Group remains busy past the DISA No Answer Time, the DISA call routes to the overflow destination or disconnects.

(What happens to the unanswered call is set by the DISA Operating Mode). The Overflow Message requires a

VRS.

Warning Tone for Long DISA Calls

You can set up the system to provide a warning tone to DISA callers that have been on a call too long. The warning tone can be just a reminder (which the caller can ignore) or can be followed by a forced disconnect of the call. When the DISA caller hears the warning tone, they have the option of Dialling a code to continue the conversation or disconnect.

Conditions

A) The DISA caller must use a DTMF dial telephone. DISA is compatible with calling devices that meet the DTMF signalling requirements of EIA Specification RS-464. DISA trunks must be supervised loop start.

B) When accessing Topaz from a remote location via a DISA trunk, a specific DISA tone will first be heard when the system answers (a fast alternating tone). After the correct password is entered to allow system access, the tone changes to a mono tone. It is at this time that allowable system features can be accessed, e.g., access code for internal paging. If the caller enters the wrong password (a warning tone will be heard), they can repeat the password entry up to 3 times before being disconnected.

Default Setting

Disabled.

Features

25-07-01 : System Timers for DID/DISA - DISA Dial Tone Time

After answering the DISA trunk, the system waits this interval (0-64800 seconds) for the caller to dial the first digit of the password. If the caller fails to dial within this interval, the system drops the call.

25-07-02 : System Timers for DID/DISA - DID/DISA No Answer Time

A DISA caller can ring an extension for this interval (0-64800 seconds) before the system sets the call as a Ring No Answer. After this interval expires, the call follows the programmed

Ring No Answer routing (see Program 25-04 below).

25-07-07 : System Timers for DID/DISA -DISA Conversation Warning Tone Time

Determine the length of time a DISA caller can talk before the Long Conversation tone is heard (0-64800 seconds).

25-07-08 : System Timers for DID/DISA - DISA Long Conversation Disconnect

This timer determines how long the system will wait before disconnecting a call after the Long

Conversation tone is heard (0-64800 seconds).

25-07-09 : System Timers for DID/DISA - DISA Internal Paging Time

This is the maximum length of an Internal Page placed by a DISA caller. If the Page continues longer than this interval (0-64800 seconds), the system terminates the DISA call.

25-07-10 : System Timers for DID/DISA - DISA External Paging Time

This is the maximum length of an External Page placed by a DISA caller. If the Page continues longer than this interval (0-64800 seconds), the system terminates the DISA call.

25-07-13 : System Timers for DID/DISA - DID/DISA Busy Tone Interval

If a DISA caller dials a busy extension (and Program 25-04 = 0), the system plays busy tone for this interval before disconnecting.

25-08-01 : DISA User ID Setup

For each DISA user, set the 6-digit password.

25-09-01 : Class of Service for DISA Users

Assign a DISA Class of Service for each user. The DISA Class of Service cannot be 0. You cannot use the 20-xx-xx and 42-xx-xx programs to assign Class of Service to DISA trunks (15 users, with one password and DISA Class of Service (1-15) for each user).

25-10-01 : Trunk Group Routing for DISA

Use this program to assign the Trunk Group Route (1-25) chosen when a user places a DISA call into the system and dials 0. Set Trunk Group Routing in Program 14-06. If the system has

ARS, Dialling 0 accesses ARS. The route chosen is based on the DISA Class of Service, which is determined by the password the caller dials.

25-11-01 : DISA Toll Restriction Class

If the system uses Toll Restriction, enter a Toll Restriction Class (1-15) for each DISA user

(1-15). The system uses the Toll Restriction Class you enter in Program 21-05. The Toll

Restriction Class assigned to a DISA call is based on the DISA Class of Service, which is determined by the password the caller dials. You cannot use Program 21-04 to assign Toll

Restriction to DISA trunk.

25-12-01 : Alternate Trunk Group Routing for DISA

Assign the trunk route that DISA Caller’s access if they dial the Alternate Trunk Route Access

Code. Refer to “Central Office Calls, Placing” for more on setting up Alternate Trunk

80-03-01 : DTMF Tone Receiver Setup
