Synopsis:

CCenablein(port,channel[,cnf_parm1[,cnf_parm2...])

Arguments:

       port – The logical E1/T1 port number.

channel – The channel number.

[cnf_parm1,cnf_parm2]..   – optional additional CNF parameters..  

Description:   This function maps to the following Aculab function:

ACU_ERR call_openin(IN_XPARMS *indetailsp);

It opens the specified port/channel to allow incoming calls to be received on that channel.       

The optional cnf_parms allow for the IN_XPARMS.cnf field to be set.      If one or more of these optional cnf_parms are specified then they are each ORed in turn with IN_XPARMS.cnf field.        If no cnf_parms are specifed then by default the IN_XPARMS.cnf field is set to CNF_REM_DISC which stops the channel automatically returning to the idle state when a remote end disconnect occurs (instead the CCrelease() call must be used to return the channel to CS_IDLE state).    

See the Aculab documentation for the call_openin() function for a more detailed description of the cnf field values.

Returns: This function returns 0 upon success or a negative error code.
