T1 and E1 using RobbedBit/CAS/R2 Protocols

Installing and Starting the Dialogic T1/E1 cards

Please refer to installation instructions supplied with your card, and contact eh card supplier if you encounter any issues starting the Dialogic service.

It is recommended that at working T1/E1 trunk is attached to the card's RJ45 port before starting the Dialogic service. Otherwise the Dialogic service may not start. A 'loopback' connector may often be used instead of the working T1/E1 trunk.

 

JCT series Dialogic cards

To configure the Dialogic "JCT" series T1/E1 cards to work with a Robbed Bit or CAS or R2 type line the following steps must be taken:

  1. The Parameter File must be specified in the Dialogic Configuration Manager.
  2. Config.xml file must have the correct protocol specified in the <Protocol> field.
  3. Optionally Dialogic's spandti.prm and voice.prm configuration files may need to be edited

Screenshot below shows where in the DCM the Parameter File is set:

The example screenshot above shows the r2_300.prm file being used on the E1 line.

A common setting for the T1 Robbed Bit lines is us_240.prm

More information on the various configuration options which can be used to configure the "JCT" series cards can be found in this Dialogic help file: springware_config_win_v1.pdf

 

DMV series Dialogic cards

To configure the Dialogic "DMV" series T1/E1 cards to work with a Robbed Bit or CAS or R2 type line the protocol family is chosen in the "Trunk Configuration" tab in the Dialogic's Configuration Manager.

The specific protocol (eg:pdk_us_mf_io) is the specified in the VoiceGuide's Config.xml file, in the <Protocol> field.

More information on the various configuration options which can be used to configure the "DMV" series cards can be found in this Dialogic help file: dm3_pci_config_win_v1.pdf

Information on the various diagnostics programs which can be used to debug the DMV cards' operation can be found in this Dialogic help file: dm3_diagnostics_win_v7.pdf

Configuring VoiceGuide

The channels which VoiceGuide is to use are specified in Config.xml file (see VoiceGuide's \conf\ subdirectory).

Sample Config.xml files are provided, and cover the most common deployment scenarios.

In the Config.xml file the Protocol files needs also needs to be set to the Dialogic protocol file which has been designed to work with the type of protocol used on the line. Common setting is pdk_us_mf_io for T1 Robbed Bit lines. The protocol .cdp files can be edited to change the Dialogic card behavior. Refer to Dialogic documentation for information on .cdp file structure and their fields.
