USED FOR PROGRAMMING THE DATA PORT Clause Samples

USED FOR PROGRAMMING THE DATA PORT. If the CV is assigned as data then it can be related to a number of parameters which can be downloaded to a SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇. The parameters are used for programming the data port of the SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇. The SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇ is connected to a DLC port via a 2B+D line. Each DLC port comprises 2 circuits which correspond to the user channels in the 2B+D line. - For a SOPHO-SET the second user channel (corresponding to an odd DLC-circuit) corresponds with the data port. - For a SOPHO-▇▇▇ either user channel (corresponding to the even and odd DLC-circuit) corresponds with the data port. - For a ▇▇▇ both user channels (corresponding to both the even and odd DLC-circuits) correspond with the data port. The DLC-circuit corresponding to a data port is assigned a DNR. A CV is assigned to the DNR as described above. This CV must be for data and subsequently have the additional interface parameters. The parameters are downloaded to the data port in the following circumstances: - Manual request with OM-command DOWNLD. - If the DLC-circuit is transferred to the service condition INS. - Whenever the SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇ is connected to the telephone line. - Upon manual request of the user. - If the OM-command CHAGCV is used. Downloading involves sending the parameters of the CV to the SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇ using the 2B+D protocol. The SOPHO-SET, SOPHO-▇▇▇ or ▇▇▇ interprets the values and programs the setting of the data port accordingly. The CV is created or changed using the OM-command CRCVAL or CHCVAL. It is assigned as either data (D) or voice (V). If the CV is assigned as data then the additional parameters can be defined. These additional parameters are separated into 4 groups: <V.24-circuits>, <speed+mode>, <miscellaneous>, <guard 1 + guard 2>. The parameters and their ranges for the SOPHO-SET 308, SOPHO-SET S375 D, SOPHO- SET P375 D, SOPHO-SET P370 D, SOPHO-▇▇▇ P375 and ▇▇▇ 308 are not all the same.
