Using the overlap_rcv feature of L4L3mENABLE_PROTOCOL

BSMI Reference Notes

Support for Overlap Receive mode are enabled using the overlap_rcv flag in the BSMI_Q931_CNFG structure of L4L3mENABLE_ PROTOCOL messages.

If the Host application expects to support Overlap Receive calling models (more typical of E1 and EURO-based BRI installations than domestic T1 installations), it should set the overlap_rcv flag to “1” when enabling the Q.931 D-channel. Example:

L4_to_L3_struct l43msg;

memset (&l43msg, 0, sizeof(l43msg)); l43msg.lapdid = 0;

l43msg.msgtype = L4L3mENABLE_PROTOCOL;

l43msg.data.enable_protocol.level1.l1_mode = IISDNl1modHDLC; l43msg.data.enable_protocol.level2.l2_mode = IISDNl2modLAP_D; l43msg.data.enable_protocol.level2.dce_dte = IISDNdirUSER_SIDE; l43msg.data.enable_protocol.level3.l3_mode = IISDNl3modQ931; l43msg.data.enable_protocol.level3.cnfg.q931.switch_type =

IISDNstUNKNOWN; l43msg.data.enable_protocol.level3.cnfg.q931.variant = IISDNvarCCITT; l43msg.data.enable_protocol.level3.cnfg.q931.overlap_rcv = 1;

BSMIControlWrite (fd, l43msg);
