I just received a brand new 2811 with a NM-HDV2-1T1/E1 module to be connected to an E1 ISDN PRI interface.
However, the integrated E1 interface just can?t establish the ISDN framing with the PBX. I inserted a VWIC2-1MFT-T1/E1 into this module, configured the port and voila! the ISDN framing came up right away.
So... it seems the integrated port on the module is DOA, but since this is a new module to me I want to be sure I?m not missing something before requesting a RMA.
Am I missing something besides issuing the card type e1 command?
Thanks in advance
