Specify the SDLCLIN parameter for 3651 retail controllers

The following table describes how to coordinate values for parameters on the iSeries™ CRTLINSDLC and CRTCTLRTL commands with bits that are specified for the 3651 SDLCLIN parameter.

The SDLCLIN parameter is specified as a series of 8 bits, designated 0 through 7 (01234567). The default value for the SDLCLIN parameter when used with an SDLC line is 01100001, or hex 61.

The default value for each bit is underlined in the Bit Value column.

To configure the iSeries server to a 3651 controller, use the following table.

SDLCLIN Bit Bit Value iSeries Parameter and Value Notes
0 0 None

Data terminal ready. There is no equivalent parameter for the iSeries system. Specify 0 to indicate that the data terminal ready (DTR) signal is on when the controller is powered on, or 1 to indicate that the DTR is off when the controller is powered on.

This bit should be set to 1 only if the configuration being defined includes IBM® world trade data communications equipment (DCE) in a switched network.

1 None
1 0 NRZI(*NO) Specify 1 if the data communications equipment (DCE) provides the clocking or if NRZI data encoding is used.
1 NRZI(*YES)
2 and 3 00 SWITCHED(*YES) CNN(*SWTPP)

Bit 2: Specify 1 if using nonswitched communications, or 0 if using switched communications. If switched, the SENDID parameter must also be specified.

Bit 3: Specify 1 if using a multipoint communications protocol, or 0 if not. 01 is not a valid combination for these bits.

01 Not valid
10 SWITCHED(*NO) and CNN(*NONSWTPP)
11 SWITCHED(*NO) and CNN(*MP)
4 0 None (See Notes) Direct attachment. This bit must be set to 0 for communications with the iSeries system. There is no equivalent parameter for the iSeries system.
1 None
5 0 MODEMRATE(*FULL) Modem data rate.
1 MODEMRATE(*HALF)
6 0 DUPLEX(*HALF) Data carrier setting.
1 DUPLEX(*FULL)
7 0 None Answer tone generation. There is no equivalent parameter for the iSeries system. Specify 0 to indicate that the modem generates the answer tone, or 1 to indicate that the controller generates the answer tone.
1 None
