4-T1-L, T1 TDM Interface - XTran Interface Module with 4x T1 LAN ports




The 4-T1-L interface module (=IFM) provides four T1 ports for connecting T1 TDM links to the XTran network. 4-T1-L refers to ‘4 ports – T1 – LAN’. T1 links are used to implement synchronous TDM links between two end points. These links typically transport voice and/or data using TDM. This IFM converts the T1 framing from an T1 link into MPLS-TP packets over the XTran network, and vice versa. A packetized TDM service is called a Circuit Emulation Service (=CES). A maximum of 16 CESes can be configured per 4-T1-L module.
