Setting the Calling Party Identification Pad String

Setting the Calling Party Identification

Pad String

The Message Center Interface (MCI) protocol, used by the NEAX 2400 switch to communicate with the SID, provides calling and called party information consistent with the dial plan administered on the switch. The SID operates on Simplified Message Desk Interface (SMDI) protocol which uses a seven-digit field. To compensate for the difference between the MCI and SMDI protocols, the SID uses a seven-digit string, called the Calling Party Identification Pad (CPID) string, that the SID overwrites with caller identification information. The SID assigns the field a default value of 0000000. For an INTUITY System, use the default CPID string of 0000000. Line 3 of Worksheet A already contains the value 0000000 as the CPID pad string.

Example: If you set the CPID pad string to 0000000 and the SID receives a caller ID of 245, the SMDI caller ID information becomes 0000245.

Setting the Message Waiting Indicator

Pad String

The Message Waiting Indicator (MWI) Pad String operates on the same basis as the CPID Pad String. As with the CPID Pad String, the SID uses a seven-digit string, called the Message Waiting Indicator (MWI) pad string, that informs the SID about the format of MWI information generated by an INTUITY System. The SID uses the MWI pad string to strip off digits not required by MCI. The SID assigns a default MWI pad string of 0000000. For an INTUITY System, use the default MWI pad string of 0000000. Line 4 of Worksheet A already contains the value 0000000 as the MWI pad string.

Setting the Message Waiting Indicator

Feature

The MWI feature enables the INTUITY System to activate message waiting lamps. The SID sets the default value for this field to ENABLE, which activates the MWI feature. If you do not want the INTUITY System to activate the MWIs, change the field to DISABLE. Write the value on line 5 of Worksheet A.

Determining the Message Center

Interface Baud Rate

You must set the baud rate for the MCI link. The SID provides baud rate selections of 300, 1200, 2400, and 9600 baud and sets a default of 1200 baud. Make sure that the baud rate equals the dip switch settings on the MCI link switch I/O card. Write the MCI link baud rate on line 6 of Worksheet A. If you plan to use the default setting, write 1200 on the worksheet.
