2-C37.94, T1 TDM Interface (Forced Power mode) - XTran Interface Module with 2x C37.94 and 2x T1 RJ-45 ports with forced power mode

This IFM converts the C37.94/T1 framing from a C37.94/T1 link into MPLS-TP packets over the XTran network, and vice versa. packetized TDM service is called a Circuit Emulation Service (=CES). A maximum of 16 CESs can be configured per 2-C37.94 module. 2-C37.94 refers to ‘2 C37.94 ports and 2 T1 ports’. T1 links are used worldwide to implement synchronous TDM links between two end points. These links typically transport voice and/or data using TDM. C37.94 is a standard for transmitting N times 64 kbps on an optical fiber, where N=1,2,…12. It is a protocol used in the power industry between teleprotection and multiplexer equipment. This card operates by default in Forced Power Mode.
