4-J1-L, J1 TDM Interface - XTran Interface Module with 4x J1 LAN ports




The 4-J1-L interface module (=IFM) provides four J1 ports for connecting J1 TDM links to the XTran network. 4-J1-L refers to ‘4 ports – J1 – LAN’. J1 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 J1 framing from an J1 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-J1-L module.
