RF300E/RF310E144
Description: S54 allows the ability to force the TA to originate digital calls with a 56Kbps or
64Kbps B-channel data rate. In some situations it is necessary to force a 56Kbps
connection. Such a situation may occur when an originated call fails to connect
because the end-to-end connection is not 64Kbps and the originating TA or the
answering TA is not informed of this situation by the network. In some situations it is
necessary to force a 64Kbps connection when the originating TA is first informed that
the call changed 56Kbps but then later returned to the ISDN and switched back to
64Kbps. By default the TA will check for Progress Indicator Information Elments
indicating changes in the routing of digital calls to determine whether the call needs
to switch to 56Kbps or remain at 64Kbps.
S-Register: S55
Usage: S55=n; S55?
Function: Information Transfer Capability for Analog Port Calls
Unit: Decimal ASCII code
Range: n=1 (Speech, no progress indicator),
n=2 (3.1KHz Audio, no progress indicator),
n=17 (Speech, Origination address is Non-ISDN),
n=18 (3.1KHz Audio, Origination address is Non-ISDN)
Default: 1 (Speech, no progress indicator)
Description: S55 allows the ability to set the type of Information Transfer Capability for calls
placed from the analog port either by a telephone, modem, or fax. Some Central
Office switches keep track of the type of line each customer has and if that line is
labeled as a data line (modem or fax), then it won’t accept a speech call originated
on that line. The 3.1KHz Audio Information Transfer Capability, however, is allowed
on data lines (modem or fax) by most switches. S55 also allows the user to indicate
whether a progress indicator information element indicating that the origination
address of the analog call is non-ISDN is sent with the SETUP message for the
analog port call. This has been found to help analog port calls get through certain
switches.
S-Register: S56
Usage: S56=n; S56?
Function: Calling Party Number IE Settings
Unit: Decimal ASCII code
Range: n=128 (Disable),
n=129 (Send Calling Party Number IE using defaults) Otherwise, n=(Type of
Number) + (Numbering Plan)

Description: S56 modifies the value of Octet 3 of the Calling Party Number Information Element
that is sent within the SETUP message for digital and analog (voice/modem/fax)
calls. To set a specific number-type and numbering plan, select an option from the
Type of Number section above and add its respective value to the respective value of
