ISDN Compatibility

Integrated Service Digital Network – Basic Rate Interface (ISDN-BRI) is a Public Switched Telephone

Network (PSTN) service that provides two B channels and a D channel (2B + D) for voice call trunking.

The B channels provide two voice path connections. Caller ID is usually a standard feature on ISDN-BRI

provided trunks. Caller ID indication displays the calling party telephone number on the LCD of the

multiline terminal for CO incoming calls. This interface provides voice communication path only.

With ISDN BRI the SV9100 only supports the following protocol:

National ISDN-1 (NI-1)

ISDN-PRI (Integrated Service Digital Network – Primary Rate Interface) is a Public Switched Telephone

Network (PSTN) service that provides 30 B channels for trunking.

Caller ID indication displays the calling party telephone number on the LCD of the multiline terminal for

CO incoming calls. This interface provides voice communication path only.

ISDN – BRI/PRI Features

DID Line Service

When configured for DID Line Service, the trunks emulate Loop Start or Ground Start trunks for

outgoing calls and DID trunks for incoming calls.

Calling Line Identification Presentation (CLIP)

Program 10-03-05: ETU Configuration – CLIP Information Announcement, allows the Calling Party

Number IE in the Setup Message for a call when placed out an ISDN Trunk.

Calling Party Number (CPN) Presentation from Station

Calling Party Number (CPN) Presentation from Station allows each unique station or virtual

extension 10-digit number (representing the DID number of the originating station) to be sent out

over the ISDN Network, if it is programmed. If no Extension Calling Number is assigned, the

system sends the calling number for the ISDN trunk. If both the extension and trunk information are

programmed, the extension information is sent as it takes priority.

Calling Party Name

If programmed, Calling Party Name allows the station name to be sent out over the ISDN network.

A system wide name can be programmed to be sent over the network or the name can be defined

on a per station basis. If both are programmed, the system wide name takes priority over the

station name.

SMDR Includes Dialed Number

The SMDR report can optionally print the trunk name (entered in system programming) or the

number the incoming caller dialed (i.e., the dialed ISDN digits). This allows you to analyze the

SMDR report based on the number your callers dial. (This option also applies to a DID trunk.)

Display Shows Why Caller ID is Not Available

With Caller ID enabled, the system provides information for ISDN calls that do not contain the
