TDM over Packet: T1 / E1 / DS3 / E3 over Ethernet

LyraTelecom offers a wide range of TDM over IP / TDM over Packet / TDM over MPLS transmission equipment with support for 2 E1 / T1, 8 E1 / T1, 16 E1 / T1, 32 E1 / T1 and E3 / DS3 / T3 for TDM over IP, MEF or MPLS, TDM pseudowire network applications.

Our Circuit emulation platform migrates existing TDM based legacy services to a next-generation networks.
