Feature Overview

The SBC 1000/2000 includes the Easy Configuration option to add a partially configured signaling group with a new single end-point scenario for ISDN PSTN.

Configure Single Leg Wizard for ISDN PSTN

The Configure Single Leg Wizard for ISDN PSTN option applies to SBC 1000/2000 only.

The SBC Easy Configuration interface includes a built-in, step-by-step setup configuration wizard to enable quick and easy deployment of a partially configured signaling group with a new single end-point scenario for ISDN PSTN.

For the single endpoint configuration, since the peer end if not known/configured, in the Easy Configuration Wizard, the Transformation and Routing entries for the endpoint being configured are created independent of the peer end. If you have two endpoints connected and use the Single Leg Wizard to add the third endpoint, you'll need to create/modify the Transformation and Routing entries to complete routing.

Easy Configuration Wizard - Single Leg Configuration Notes
  • A single leg wizard should be used to add a 3rd, 4th, 5th peer to device, when at least 2 legs have already been configuring via the standard Easy Configuration Wizard.
  • Emergency configuration is not supported for single end scenarios.

  2. Click Next.

The fields below are displayed if you select ISDN/PSTN from the Application drop down list in Step 1. 

Configure ISDN PSTN Parameters

FieldDescription
Port TypeSpecifies the physical T1/E1 port used for this Signaling Group. Valid option: T1 or E1.
DS1 Ports

The physical T1/E1 port number to which the PSTN line is physically connected. DS1 entries are configured with the following command buttons: Up (move a DS1 port up in the list), Down (move a DS1 port down in the list), Add (adds a DS1 port), and Remove (deletes a DS1 port).

For example, click Add. Select the desired PSTN port and OK.

Switch Variant

Specifies the ISDN variant for the port type in the ISDN Signaling Group.

For T1

  • ATT 4EES
  • ATT 5EES
  • DMS 100
  • N12
  • Euro ISDN
  • QSIG
  • Japanese ISDN

For E1:

  • Euro ISDN
  • QSIG
ISDN Number TranslationDetermines if the SBC should translate dialed PSTN digits as phone extensions. Valid options: Translation Extension (translates digits into phone extensions) or Passthrough Untranslated (does not translate digits).
PBX PrefixNumbers to prefix for the translated phone extension. This field is available only when ISDN Number Translation is set to Translation Extension.
Extension LengthThe number of digits used to account for the PSTN extension. Valid options: 2, 3, 4, or 5.This field is available only when ISDN Number Translation is set to Translation Extension.
Clock Source

Specifies the source of the systems transmit clock.

  • System: The built-in oscillator is used to transmit data over synchronous links.
  • Network: The clock is derived from the data received from the peer devices on the network.
Primary Clock PortSpecifies the primary port for the clock source. This field displays only when Network is selected as the Clock Source.
Secondary Clock PortSpecifies the secondary port for the clock source. This field displays only when Network is selected as the Clock Source.
ISDN SideSpecifies the ISDN user/network side for this signaling group to be created by this wizard. Valid entries: Network or User.
