tdmaBcModemOutbandFlowControl 1.3.6.1.4.1.562.2.4.1.136.3.10.1.8

This attribute indicates whether outband flow control conversions are being performed. If outband flow control is on, then when the Modem Application Layer (MAL) receives an xon or xoff from the PSTN, the MAL converts the instruction into a primitive and sends it to the Data Service Control (DSC). In the opposite direction with outband flow control on, when the MAL receives a primitive from the DSC, the MAL converts the primitive into an xon or xoff and forwards it to the PSTN. If outband flow control is off, then all flow control is handled inband. The modem performs either inband or outband flow control unless V.42 layer is active, it is a fax call, or no flow control was specified by the DMS-MTX. This attribute has one of the following values: on: Conversion to and from out-of-band signaling is enabled. off: Conversion to and from out-of-band signaling is disabled.
